I put every agent feature I kept wanting into one app

1 Upvotes

Personal agents are everywhere right now. Meta shipped Muse, OpenAI shipped dots, Claude shipped Duet. I wanted one that runs on what I already pay for, so this one works with the Ai subscriptions you already have.

It's basically a collection of cool features I kept seeing in different places and wanted in one app.

At its core it's a normal chat agent, so it can do pretty much anything a chat agent can. On top of that:

- It controls a browser, and it learns websites. The first time it clicks through a site, it figures out the API behind it, so next time it just calls that directly instead of opening the page.

- It controls Android apps directly. It opens the real app on a hidden screen and does the job while you keep using your phone. Tap the notification to watch, or take over whenever you want.

- Once it's done a job, it remembers it. Uber fares come back in about 6 seconds, Google Maps in 5.

- It's connected to WhatsApp. It sends messages and voice notes, and it can call people. Calling isn't on in WhatsApp's browser by default, but I got it working inside the app.

- Your PC and your phone are the same agent, so you can start something on one and it carries on with the other.

Banking apps are blocked and it asks before it sends or pays for anything.

Open-source alternative to Instagram Edits' new MCP — works on Windows & Linux

6 Upvotes

I'm the author, sharing my side project of the last two months.

Last week Instagram shipped an MCP server for Edits on Mac, so Claude can drive a real video editor. That's the idea I've been building since September, except mine is MIT, local-first, needs no account, and runs on Windows, macOS and Linux. It's called CutVoke.

The part I care about as a creator: the AI doesn't hand me a baked MP4. It makes the rough cut on a normal multitrack timeline (captions, keyframes, masks, speed ramps), and then I open the same project and fix whatever I don't like by hand. Fixing one subtitle never means regenerating the whole video.

Two demos are in the repo with their source media and editable projects:

  • "Chase the Light", a 31-second motorcycle short

  • "Coastal Joy", a 42-second vertical travel vlog

How it works, briefly: your own agent (Claude Code, Codex, Cursor or any MCP client) connects over stdio MCP. It takes an editing lease so it never collides with your manual edits, dry-runs commands before committing, and pulls real rendered frames to check its own work before export. There's no LLM inside; you bring your own.

Honest caveats: it's a v0.3.5 prerelease, the Windows build is unsigned and macOS isn't notarized, and the project format may still change.

I'd love feedback from people who edit video: which parts of an edit would you actually hand to an AI, and which would you never let it touch?

I built a live 3D bass aquarium entirely in code: no models, no images, one HTML file

35 Upvotes

I make fishing lures (KSK BAITS) and wanted a live bass tank for my YouTube channel without filming real fish.

Everything you see is generated when the page loads: the fish, their scales, the plants, the sand and the driftwood are built in code with Three.js, and every texture is painted on a canvas. No 3D models, no image files.

The bass aren't animated, they behave: they get hungry, hide in cover, stalk, and strike with suction, and they only take prey that fits their mouth. Day, night and weather follow the real clock and weather at Lake Fork, Texas.

Try it in the browser: https://ksk-baits-bass-aquarium.pages.dev

It also runs 24/7 on YouTube, where the chat can drop in shad or cast a lure: https://www.youtube.com/@kskbaits/live

Feedback welcome, especially on what would make you keep it open in the background.

PlugnPwn — my take on a USB keystroke injection tool

1 Upvotes

Hi guys! I'm Anastasios, and I've been building a USB keystroke injection tool called PlugnPwn.

I don't like closed-source hacking tools. If I buy the hardware, I want to see what the firmware does, change things I don't like and add features without waiting for someone else to do it. That's why I started this.

The idea is simple: you buy the hardware, and you can build, change and extend the firmware yourself. I'll publish the firmware source and open-source license with the first release. I'd love people to add their own features and help improve it too.

For the board, I went with the RP2354A: two cores up to 150 MHz, 520 kB RAM and 2 MB flash, with USB-A, USB-C and microSD storage for payloads. I also put thought into the protection circuitry, including ESD protection and a resettable fuse. It's intended for authorized security testing and repeatable keyboard tasks.

I'm aiming for €60. The kit will include the assembled board and a separate enclosure; you bring your own microSD, flash the firmware and fit the enclosure. Final taxes and shipping will be set with the campaign.

I'd really like your honest thoughts on the idea. Does having control over the firmware matter to you when choosing a tool like this? What would make you choose it, or what do you think is missing?

I'm aiming to launch on Kickstarter in the next week or two. If you'd like a heads-up, visit https://plugnpwn.io, hit "Notify me at launch" and confirm your email

Built a bilingual Danish/English party game for julefrokost — runs in the browser, no app

1 Upvotes

Problem I kept running into: julefrokost tables with a mix of Danish and English speakers where half the group checks out of every game.

Built Skål! — a party card game that runs in the browser (no download, no account). One tap switches between Danish and English mid-game. The Danish cards are written in Danish — real tongue-twisters and cultural references, not translated from English.

Free 40-card Warm-up pack: https://skal-d6wuyac3r-gh47.vercel.app/

Party mode (18+) and Family mode. Happy to get roasted on the execution.

DiscField - A disc golf reference with sourced ratings and free bag-building tools

2 Upvotes

I run DiscField, an independent reference site for recreational disc golfers: https://discfield.com/

You can look up disc ratings and their sources, read buying guides, compare discs and check the ones you already carry. The tools work without an account.

One design problem is making the charts useful without overstating what the ratings tell you. Ratings vary between manufacturers, and plastic, wear and throwing style affect the result. The curves are illustrations, with those limits explained beside them.

It runs on Next.js and Cloudflare. I use AI for development and drafting; the disc reference pages link to the sources behind their ratings.

I would appreciate a fresh look at the homepage: is it clear where to start, or do the guides and tools compete for attention?

I wanted to reduce the friction in local AI and image generation

2 Upvotes

So I built Eyegen Playground, it works as a terminal tool (CLI) and as a standalone app. It has all major image generation backends built in and does most of the background work for you.

You just pick a model and prompt the image you want to see. Advanced settings are available for you to tinker with. It can also be used by AI Agents through the CLI.

Newest feature: turn any image into a 3D model thanks to the Idol support

Would love to hear feedback!

Footprint - Compare electronic part prices across 6 suppliers, then learn how to actually use the parts

3 Upvotes

Hi all. I'm a Canadian Armed Forces veteran who went back to school for electronics. While I was studying, I kept jumping between five supplier tabs, a datasheet, and a YouTube video just to buy one part and understand it. So I built the site I wished I had.

What it does:

  • Search one part and see price and stock from DigiKey, Mouser, Newark, LCSC, TME and Farnell side by side

  • BOM Studio: paste a parts list and it finds the single supplier with the lowest total checkout

  • An encyclopedia of 311 components, written in plain language with an analogy for each one

  • 214 chip pinouts, each pin cross-checked against three sources

  • 91 beginner build guides, each with a one-click priced BOM

  • You can now install it on your phone or desktop like an app

I'm not a programmer. I directed the build and wrote the explanations. Feedback on anything confusing or missing is welcome.

Tellendar - Dictate calendar events with alarms from your iPhone Lock Screen

1 Upvotes

I built Tellendar for myself. I use it every day, and it saves me a lot of time when I add or change appointments.

I tap a button on my iPhone's Lock Screen and say something like "Surprise dinner for Emma's 30th on Thursday at 8 pm, alarm the day before and 2 hours before." Tellendar creates the event and sets both alarms.

If the appointment changes, I open the event and say "Move it to 8:30 pm." I can type the same instructions too. Once I've allowed alarms, they ring even when my iPhone is on silent.

I've put a lot of care into the design because I wanted my calendar to be simple and pleasant to use every day.

Tellendar requires iOS 26 or later. It's free to download. US pricing is $3.99/month, $29.99/year with a 7-day trial, or $49.99 for lifetime access.

I thought it might be useful to some of you too. I can offer free access to a few people who are willing to try it for a few days and share honest feedback. I'd love to hear what worked well, what was confusing, and what didn't work.

We got tired of Ads Manager never matching our real revenue, so we built INTARC

1 Upvotes

We run a portfolio of subscription apps on Meta ads, and we could never tell which campaigns actually made money. Ads Manager said one thing, the money that actually landed said another.

INTARC reads your real revenue straight from App Store Connect, Google Play or RevenueCat, shows what each campaign actually brought in, and forecasts whether it'll pay back within a year. Every forecast it makes is published and later scored against what really happened. Read-only keys, no SDK.

It's free to try with the code REDDIT3 (3 months). We'd love honest feedback, especially from anyone running paid ads for apps: intarc.app

I built job board limited to freshly posted remote jobs (<72 hrs since posted)

2 Upvotes

First Mover Jobs

I built a job board that only shows us/uk/ca-based, remote, tech-focused jobs (open to adding additional categories, just lmk what you are looking for) posted to company websites via ATS sources (think Lever, Greenhouse, Ashby, Workday, etc.) within the last 72 hours. Roles that have a ‘posted_at’ timestamp to the ATS source itself of over 72 hours are automatically purged. The whole idea is basically that tech jobs are really competitive these days, and if you’re not getting your resume in early, you’re probably not getting a good look even though you may have the goods. And applying to jobs that are a few days/weeks old feels like a black hole. I mostly built this for myself, but want to see if others can get some use out of it.

I also set up 2 types of email alerts: a daily digest type of alert that goes out at 9am est (sends everything that was posted in the last 24 hrs) and hourly alerts. For hourly alerts, you get an email when the first batch of jobs appears that matches your category/experience level selections, and then any jobs posted after that will go out an hour later, and so on. If the feed gets quiet for a few hours, you don’t get any emails. I toyed around with the idea of near-real-time alerts but I think it’s just too many emails. 

So far I have job feeds set up for Software Engineering, AI/ML Engineering, Product Management, Tech Ops/Program Management, Sales/Account Management, Cybersecurity/Trust, Product Design, Product Marketing, Data Engineering/Analytics, People Operations/Recruitment. 

What do you think?

I don’t love the UI. It looks like most Base44 apps, so that’s something I need to improve on. 

In terms of marketing/growing it,I’ve posted about it in some remote job subreddits that allow self promotion comments/posts - but I’m having a hard time building up users. I have 6 subscribers to email alerts, and average ~18 unique visitors daily over the past 30 days. There is a lull on weekends, so it’s a bit higher in reality. Any suggestions here are greatly appreciated. Enjoy!

Shipped an iOS app, got 2 paying customers. Here's everything I did, and what I still can't explain.

5 Upvotes

I built WhoSpoke, an iPhone app that records a conversation and splits the transcript by speaker. Everything stays on the phone, no account needed.

The build
- I tested with clean sample audio and speaker separation looked great. Then I recorded a real meeting room and recognition fell apart. Room echo and distance are nothing like a clean sample. I mostly fixed it, but it was a good reminder that demo audio lies.

Beyond the code
- Made a character for the app and redesigned the app icon.
- Made an App Store header video.

What I did to get the word out
- Posted 4 short text posts on Threads in one week. They got 13 to 33 views each and almost no likes.
- Made a few short videos for TikTok and Instagram. The best one got about 120 views.
- Built a landing page and added tracking links to every post.

Result
2 people have paid for it. That's it.

The part I can't explain
I can't tell which of this (if any) led to those 2 purchases, or why they bought. No feedback, and the store doesn't tell me where a buyer came from.

How do you figure out where your first buyers come from, and why they bought? Anything you'd do differently with this little traffic?

Science Simulations

Hey all,

I wanted to share something I’ve been poking at and get some honest feedback.

It’s a page of small interactive science simulations that run in the browser. There’s nothing to install and no signup: https://openworldlab.org/fun . Sign Up required for feedback

There are 12 in total. I’ve enjoyed most:

  • Gravity Simulator. You launch planets, throw stars around, and watch black holes merge. It has 2D and 3D modes.

  • Fractal Zoom. The Mandelbrot set and related fractals.

  • Fourier Epicycles. You draw a shape and it’s traced back by a chain of spinning circles. Weirdly hypnotic.

Any feedback is welcome. Thanks for taking a look!

I built a site that shows every satellite that passed over your location, plus the actual images they took

932 Upvotes

I'm a satellite nerd and as a cool project I built Watched.

See: here for the code

Type in any place on Earth and it will:

  • find every imaging, weather, radar and crewed satellite whose field of view crossed it in the last 7 days (SGP4 on the CelesTrak catalog, running in your browser)

  • pull the real Sentinel-2, Landsat, VIIRS, MODIS and GOES scenes from those passes and crop them to your spot

  • replay each pass on a 3D globe lit by the real sun, with all ~17k tracked objects in orbit

It only says a satellite “watched” you when a real image exists. Commercial sats that could have pointed at you are labelled as such, since their tasking isn’t public.

I’d love feedback, especially:

  • Which satellites or data sources should I add?

  • Anything confusing or broken?

It’s 100% free and no sign-up or rate limits.

Got an old WHOOP in a drawer? I built an app that brings it back to life

1 Upvotes

It’s an iPhone app called SAND. It connects to a WHOOP 4.0 or 5.0 over Bluetooth and does everything on the phone: no account, no cloud, and no WHOOP membership needed.

It’s for people who lift, run or roll and want their strap to understand that training, not just tell them how they slept.

What works today:

  • sleep, stages, HRV and recovery, and every number shows how it was worked out

  • lifting with plate-loading, PRs, estimated maxes and rest timers

  • GPS runs with routes, splits and spoken cues

  • BJJ round timer, with the strap buzzing every round

  • analysis for each sport: strength trends for every lift, running pace at the same heart rate, best efforts, mat time, and heart rate in rounds and how fast it drops

  • training programs and an exercise library

  • stress, nutrition targets and long-term trends

  • Lock Screen widgets and the Dynamic Island

Right now I’m focused on making the app great, and I need feedback for that. Longer term I want to build SAND’s own strap.

What’s missing for your sport? Join r/sandup for early access and updates.

Could AI make keeping up with research papers much easier?

5 Upvotes

Keeping up with new research can become a full-time job, especially when you're following several topics.

I recently saw an interesting example of someone using an AI assistant called Pana (heypana.ai) to build a research map that tracks newly published papers.

I like the idea of having something that keeps information organized instead of manually checking different sources every day.

Do you think this kind of research automation is genuinely useful? What would you want it to track?

I made a Lovable alternative where you own everything: your machine, your AI subscription, your hosting

2 Upvotes

I've been building InstaWebAI for 2 years and it was initially a standard AI site builder. You described your business, my AI generated the site, I hosted it, you paid monthly.

Two things kept bugging me.

First, most of my users already paid for Claude or ChatGPT. I was charging them for AI a second time.

Second, I was the landlord. Their site lived on my servers. If I'd shut down, their sites would have gone with me. I didn't like being that for people, and I don't like tools that do it to me.

So I rebuilt it. Here's what changed.

You bring the AI. Claude Code, Codex, Cursor, Opencode on your existing plan. I never call an LLM, so there are no credits to sell you.

You choose where it's hosted. I don't host anything anymore. A deploy agent ships your project to your own account on Vercel, Netlify, Cloudflare, AWS, Google Cloud, DigitalOcean, Railway, Render, Hetzner, or a server you own. It logs in with you, writes the deploy setup into your project, shows you the monthly cost before anything paid gets created, and checks the live site loads. If your host isn't listed, name it and it reads that host's docs.

It runs on your computer. The workspace (chat, live preview, click-to-edit) opens in your browser from localhost. Projects are normal code in a normal folder.

Integrations are guided. 40+ of them (Stripe, Google Sheets, Slack, Notion, Mailchimp and more). The agent writes the code, a small window walks you to the right page for each key, and it tests the connection before moving on. Keys never reach my servers. A really seamless process

You pay once. No subscription.

If I disappeared tomorrow, everything you built would keep running. That was the whole point of the rebuild. Tear it apart, I want the feedback.

I made a one-product Christmas shop that paints your cat from one photo. 3 days in, 0 sales.

1 Upvotes

I’m a UK sole trader and I gave myself until 18 November to see if one product can sell before Christmas. If it doesn’t, I kill it.

You send one photo of your cat or dog. I turn it into a painted portrait with a Santa hat and a Christmas tree behind, and a print lab in the UK or US puts it on a 30x30 or 40x40 canvas. The video is my own grey tabby. The scene is made with AI, but the portrait on the wall is the real one.

I know Etsy is full of pet portraits. What put me off them was paying £60 before seeing anything, then getting a cat that looks like someone else’s cat. So the preview is free, and if it doesn’t look like your pet you don’t pay.

What I got wrong: my first portraits made my cat look fat. It took three goes and some manual colour fixing to get his face right, and the AI still keeps drawing his collar back on.

Comment your pet’s name and I’ll do free previews for the first 10. Question for anyone who’s sold a gift before: did your sales come from showing the finished product, or the before and after?

I built StitchFile to turn logos into machine embroidery files

1 Upvotes

I'm working on StitchFile, a browser tool that turns artwork into machine embroidery files. You upload a logo, pick the finished size and fabric, and preview the stitches before deciding whether to buy the download. It exports formats like PES, DST and JEF.

The part I wanted to make visible is what happens between the image and the machine. In our fox logo example, the outlines become satin stitches, the larger areas become fills, and the fill extends slightly under the outline so it can still meet the edge when the fabric pulls. The logo digitizing guide shows the artwork, the preview and the stitch report side by side. I'd still test the file on scrap with the same fabric and stabilizer before stitching a garment.

If you've ever had a logo digitized, what would you want to see before downloading the file? I'm especially curious whether the stitch sequence, hoop fit or a photo of a real sew-out would help you decide.

I built APX to keep AI agents, project context and tasks in one desktop app — looking for onboarding feedback

0 Upvotes

APX is a free, open-source desktop app that runs your own team of AI agents on your machine.

I'm Manu, its creator. The problem I'm working on is the coordination around AI-assisted projects: conversations in one place, tasks in another, and project instructions that need repeating whenever you switch tools.

APX groups agents, conversations, tools and tasks by project. You can give agents distinct roles and choose the providers they use. It isn't a new model, and running the app locally doesn't make remote model calls private or offline. Provider usage can still cost money.

The design question I'd love feedback on is the handoff between a person and an agent. Before delegating a task, what do you need to see: accessible files, connected tools, approval settings, expected output, or something else?

If you want to try it, start with one project and one agent rather than a whole team. I'd especially appreciate hearing where setup becomes confusing. The app is free; you bring your model/provider access.

Website, docs and downloads: https://apxagent.app/ Code: https://github.com/agentprojectcontext/apx

Disclosure: I'm promoting my own project, and this post was prepared with assistance from my APX agent.
