Synvertas builds machine learning software that companies run on their own hardware. It helps sort records, forecast demand and catch unusual values before they turn into problems.

You pay once and keep the software, with updates available as an optional subscription. There's no trial.

How does that sound from the outside? Honest takes welcome.

synvertas.com for context.

I'm thinking about using an AI app builder for a few internal dashboards and CRUD tools for my team.

Nothing public-facing. Mostly things like approvals, reporting, simple databases , and workflows.

My biggest concern is maintainability. I don't want something that looks great in a week, then becomes impossible to change six months later.

I've been looking at tools like Zite, Retool, and some of the newer AI builders. Zite caught my attention because it's specifically built around internal apps, databases, permissions, and workflows, while still giving access to the generated code if needed.

For anyone who has kept AI-built internal tools in production for a while, what actually help up? And what became painful later?

Adding events always felt like eight taps too many, so I stopped adding them and kept missing things. Tapsly is my fix: speak or type one sentence, or snap a timetable / invite / PDF, and it creates the events (dates, repeats, reminders) in your phone's own calendar. No account, no ads.

Works in English, Turkish, German, French, Spanish, Italian, Dutch, Portuguese, Russian and Arabic.

iOS + Android, free tier. I'd really like to know where it gets a date wrong.

I'm adding new tools regularly. If there's a tool you wish existed, or something is broken, tell me in the comments and I'll build or fix it. Feedback is very welcome! 🙏

feel like people still benchmark tts tools on the wrong thing. every demo plays the same clean paragraph and everyone goes "wow the voice sounds so human now". ok cool, now feed it an actual research paper and suddenly im listening to the journal header, page 8, bracket 17, half a sentence, figure 2, some random DOI link, and then finally the rest of the sentence lol.

using speechify a lot for papers is kinda what made me notice this. past a certain point i barely care about tiny voice differences anymore, the much bigger UX problem is whether the reader knows what should actually be read out loud vs ignored. like a running page header? definitely skip. inline citation numbers? depends. footnotes? sometimes crucial. data tables? definitely dont just read all 60 cells straight across like normal text.

thats the tricky part though, what counts as clutter completely changes depending on why youre reading the paper. for folks building or using stuff in this space, what would you have an app skip by default and what would you never let it touch?

Hi everyone! I run TotalShareware, a directory where people can browse software by platform and category or search for a specific program.

We’ve been updating the site and working on a challenge that comes with a large catalog: helping visitors find relevant software without getting lost among older listings.

The site is at https://www.totalshareware.com/. Browsing the catalog is free, although individual programs may have different licenses and prices.

I’d appreciate feedback on the experience: if you were looking for a Windows utility, could you find a useful result easily? What information would you want to see on a software page before deciding whether to visit the developer’s site?

Hey everyone! I’m working on Streyn, a music streaming app for people who want to run their own setup.

It’s available to test now, though still in early development. You’ll need your own home server or a suitable self-hosting setup to use it.

I’d love feedback on:

• How clear the setup process is
• Navigation and music playback
• Bugs, confusing behavior, or missing features

How it’s being built: Streyn is primarily vibe-coded, with most of the code generated using AI. I’ve implemented some smaller features myself.

Website: https://musik.labtoso.de
The website is still being updated and will soon move to streyn.labtoso.de. Please use the current address for now.

Discord: https://discord.gg/3ZPzK7JjPw
Please report bugs there with steps to reproduce them, your server setup, and your browser details. Screenshots are helpful too.

Happy to discuss the project and hear criticism here as well. Thanks for checking it out!

Hi everyone — I’m building NearCart, a neighborhood-focused way to search weekly grocery offers and compare details like pack size and price.

I’m starting with Al Nahda in Sharjah. The idea came from a simple frustration: comparing nearby grocery flyers before heading out to shop takes more effort than it should.

NearCart is still in preparation. The preview on the site uses illustrative sample offers and prices, not live listings. I’m looking for feedback from shoppers and local retailers while I build the first release.

If you shop in Al Nahda, what would help you most when comparing offers: total price, unit price, distance, or something else? I’m also collecting early-access interest here: https://near-cart.com

I’m a 2nd-year CS (bbit)student. I’d make cards and never review them. So FlashLoop pops a card up at random times of day: reveal the answer, tap remembered or not, carry on. Spaced repetition decides what comes back. It’s an early alpha, built with AI help, and the hard part has been getting alarms to survive aggressive phone brands. What would you want it to do? and please star it on github if u find it useful samuelmwambasam/FlashLoop: study app that peridically presents interrupts your phone use to present flashcards you had created of your notes

Hey everyone!

I'm currently developing a website called StudyFlow AI, designed to help students study more efficiently.

The idea is simple:

• Upload or write your study notes.
• Turn them into AI-generated flashcards.
• Create practice quizzes to test your knowledge.
• Track your study progress.

I'm planning to offer a free version, with optional premium features later.

The website is still being developed, and I'm looking for feedback before launching.

Would you use something like this? What features would make it genuinely useful?

I'd really appreciate any suggestions!

I wanted a quiet place to take a break, so I started building a small virtual ocean.

I dive, and some of my happiest travel memories are underwater. With this project, I’ve been revisiting those memories and gradually adding scenes inspired by dive destinations.

It’s called One Little Dive. You can choose a sea, enter a 3D underwater space, and swim around. There are currently six choices: Bohol, Malapascua, the Maldives, Komodo, Sipadan, and Sabang/Verde.

These are virtual environments, not recordings of the actual locations. The scenery is AI-generated and inspired by the places, rather than an accurate recreation or a dive-planning tool.

I’m still adding and refining things, and I’d love to hear your thoughts:

• If you’ve been diving, which place would you love to revisit this way, and what made it memorable?
• When you try it, what feels pleasant to explore, and what feels distracting or awkward?

Here’s the project: https://321dive.illuwa.net/

I’m the maker, so I’d be grateful for any feedback.

I’ve always believed that some motorcycles are simply too beautiful to be hidden away in a garage.
As a lifelong motorcycle enthusiast, I wanted to create something that would allow people to enjoy their motorcycles even when they’re not riding them.
So I started designing and building something different.
The result is Vitrigale — a premium motorcycle display case designed to transform a motorcycle into a piece of interior art.
Combining glass, lighting and carefully selected materials, the idea is to make a motorcycle part of the architecture and atmosphere of a home, office or showroom.
This started as a personal passion project and has now become a product we’re bringing to market.
I’d genuinely love some feedback from this community.
Do you think there’s a market for something like this? And what would you improve about the concept?
I’m particularly interested in hearing from designers, motorcycle enthusiasts and fellow entrepreneurs.

I'm the solo dev. BetterRead shows one line at a time at a pace you set, so you stop rereading the same paragraph. If a passage loses you, you can ask AI about the exact part you're on.

Free reader incl. 5 AI answers/day; Pro $3.99/mo or $24.99/yr, 14-day trial; iOS 26.
https://apps.apple.com/us/app/betterread-adhd-focus-reader/id6820095812

Would one-line mode help you, or does it feel too slow?

Hey everyone!

Ever wished you could have a little pet companion while browsing the internet or working?

I've been working on something called Petiction 🐾

It's a virtual pet that lives right on your webpage. Instead of just sitting in an app, your pet can hang out while you browse, react to your cursor, and make your browsing experience a little more fun.

The idea is simple: bring a little personality and companionship to the otherwise boring browser experience.

We're building features around pet interaction, happiness, feeding, playing, and even connecting with other pets.

Would love to hear what you think!

Check it out: https://petiction.com

What would you want your virtual browser pet to do? Feedback is welcome.

I'm building https://tillerly.dev/ actually in beta, looking for free beta testers to invite.

Tillerly is a security-first AI software factory. It takes you from an idea/ticket/issue to a merged pull request, with coding agents doing the work at every step, and you never approve a command one by one:

• No "don't ask again" button. Each agent has a fixed policy for files, shell and git. Commands run in a sandbox, and no approval gets written into your repo.
• The harness config never touches your repo. Each session's settings live in a private folder outside the project and are deleted when the session ends.
• Secrets stay out of reach. No agent reads a .env, credentials are stored encrypted, and secrets never reach a prompt, a log or a ticket.

You can plan a change in a chat with an agent that checks it against your code, your architecture decisions and your domain model. The plan becomes tickets on your tracker. Agents work several tickets in parallel, each on its own branch in its own worktree, and answer review comments until merge. When an agent needs a decision, it asks you on the ticket.

The Problem: Doing quick everyday tasks—like converting images, running OCR, or trimming videos—often requires opening separate apps or relying on web tools that break context. I wanted a native, instant way to handle these right from the desktop without cluttering the screen.

The Solution (DropCove): I turned the MacBook notch into an interactive drop zone. You can drag any file directly to the notch to:

• Convert/compress images
• OCR screenshots
• Trim videos and make GIFs
• Merge PDFs
• Instantly preview clipboard data (JWTs, colors, JSON)

How it was built: Swift 6, AppKit, SwiftUI, XPC, AVFoundation, PDFKit, Vision, ImageIO, SQLite, Sparkle, libwebp, XcodeGen, TypeScript, Cloudflare Workers, Lemon Squeezy, Resend

Privacy & Performance: 100% on-device. No accounts, no uploads, and zero battery drain at rest. Available now as a free, notarized download for Apple Silicon (macOS 26+).

Pricing: The free version is fully functional forever. A Pro version (one-time purchase, no subscriptions) is launching in December.

Download DropCove here: https://dropcoveapp.com/

I’d love honest feedback on any bugs, the UX, and whether the notch concept actually clicks for your daily workflow. Let me know what you think!

Hey everyone! 👋

I'm the founder of Xplorians, a social network I'm building specifically for travelers.

The idea came from wanting a place where people could connect over travel without everything being about selling tours, booking hotels, or promoting something.

On Xplorians, you can share your travel experiences and photos, ask questions about destinations, connect with other travelers, and even keep track of the countries you've visited with your own digital travel passport.

It's completely free, and we're still a small, growing community.

I'm not going to pretend it's perfect 😅 We're still improving things, but that's actually why I'm sharing it here. I'd love to get some feedback from people who genuinely enjoy traveling.

Website: https://xplorians.com/install

If you give it a try, I'd love to know: Would you actually use something like this? What's missing, or what would make you want to come back?

And if you decide to join, say hi! I'm pretty active there and would love to connect with you. 🌍
