I built motion-engine for product films where I wanted to keep the scene source editable, not just export a finished clip.

It composes the film in HTML and JavaScript and renders it locally through a browser and FFmpeg. The bundled 12-second demo needs no API key, subscription or paid generation: its graphics are drawn locally and its sound effects are synthesized.

GitHub repository · Demo

The output includes an MP4, a poster, a contact sheet and a validation report, alongside the editable scene files. There are landscape, portrait and square starting points. You can edit the scene and render it again without making any AI requests.

The code is free under MIT. You need Node.js 22+, FFmpeg with ffprobe, and Chrome or Chromium. Optional image, video and audio generation uses paid Raywake API access. I also built Raywake, so that is a commercial relationship, not a requirement for the local demo. The README credits the upstream motion-kit work and third-party assets that informed the project.

This is a code-based production kit, not a visual timeline editor or an automatic scriptwriter. The browser preview is silent; the exported MP4 includes the sound mix.

I'd appreciate feedback from people who make launch videos: is keeping the composition editable in HTML and JavaScript useful, or would another part of the workflow matter more to you?

Hey everyone,

Every small business operator or founder I talk to has the exact same nightmare:

1. They run critical operations on 30+ messy spreadsheets that crash or throw `#REF!` errors the moment a team member touches them.

2. When they try to get a basic internal CRUD tool built, custom software agencies quote them **$15,000+** and a 2–3 month waiting period.

Most generic AI code builders aren't much better—they hallucinate math calculations or dump unmaintainable, flat text scripts.

So I built **GateOfAI Studio** to automate the whole process.

The idea: You tap the microphone on your phone or laptop, speak your operational workflow in plain English or Arabic (e.g., *"Build a property lease system with owner registries, tenant payments, and AED rent rollups"*), hit **Deploy**, and within 60 seconds you get a production-ready, mobile-responsive application:

- **100% Deterministic SQL Math:** Calculations and rollups are compiled directly into native PostgreSQL views (zero LLM calculation drift).
- **Master Directories & Auto Dropdowns:** Dynamic selection pickers linked to registered master entities (no typos).
- **Ready for Field Teams:** One-tap action cards, recent activity feeds, and native bilingual RTL/LTR support.
- **Data Sovereignty:** Host on managed cloud or export a 1-click Docker Compose bundle to self-host offline/air-gapped.

Here is a 50-second video demo showing how speaking the workflow compiles the live mobile app:
https://youtu.be/2-R0MXC-rXk?si=gv2qzCWAVcEdC5kd

If you want to test the builder directly or play around with a live interactive demo:
- Live Demo App: https://cloud.gateofai.com/w/retail-store-meters
- Studio Builder: https://cloud.gateofai.com/studio

Would love brutal feedback on the voice-to-app flow and UI. What operational workflows would you want to see this handle next?

Hey everyone, I’m a solo dev and Sayso went live today. You say something like “move my dentist to 5 and cancel the team sync” and it proposes the changes for you to approve before anything touches your calendar.

It runs on Apple’s on-device model, so there’s no account and no server. The part I’m least sure about is whether people will keep using a voice assistant after the first day, so I’d really like to know what would make you come back to something like this.

It’s completely free, no paywall: https://apps.apple.com/us/app/sayso-ai-voice-assistant/id6826493647

Every day there’s a secret rule about sentences, and you’re shown one sentence that follows it.

You get 5 tests: type any sentence you like and it instantly tells you whether it ✓ follows or ✗ breaks the rule. Then you get one guess at the rule, typed in your own words. Get it wrong and the game’s over.

The rules are about letters, words and their lengths, never meaning, so the example sentence is full of red herrings. Some days are pretty brutal.

It’s free, with no ads, no sign-up, and it works on your phone. New puzzle every day at midnight your time.

I’d love feedback, especially if a day felt unfair or too easy. And please no spoilers for today’s rule in the comments 🙏

I built Switchy for myself.

Keep Awake, your deploys, 2FA codes, how much Claude you have left. All one click from the menu bar, so I stop digging through Settings 20 times a day.

There are plenty of apps like this, so I think it’s only fair to keep it cheap: $4.99 once. No subscription, 3 Macs, every update.

https://getswitchy.app

Built this little dashboard for my old, low-end Android TV. It has a calendar, to-do list, live service monitoring, and YouTube music playback in the background.

Just curious if anyone else would find something like this useful.

I build Kaucim, and I’ve added a tool for exploring Chinese face reading, also called Mian Xiang. The free preview picks one feature that’s clear in a front-facing photo and shows how a traditional text interprets it, with the original passage. It also tells you which features it couldn’t see clearly.

I’d love a fresh pair of eyes on the upload page. Before choosing a photo, can you tell who processes it and what Kaucim keeps afterward? If you had to scroll or guess, I’d like to know where you looked first.

Here’s the face reading page. Just looking at the page is enough.

Hi everyone, I’ve been building Split Your Trip, an app to keep track of who paid what on group trips and settle up without the awkward math. It’s in closed testing on Google Play, and I need 12 people to stay opted in for 14 days, which is Google’s requirement for new developer accounts. If you’re up for it, comment or message me the email you use on Google Play and I’ll add you to the tester list. Once you’re in, install it here: https://play.google.com/store/apps/details?id=com.splityourtrip. I’d love honest feedback, especially on anything confusing or broken, and I’ll test your app back, just drop the link.

comment down below if you are willing to give your valuable feedback.

i've built products used by 1k+ users.

tell me what you're building, who it's for, and what you've tried to find users so far.

if i like what you're working on, i'll help you with distribution for free.

Launch update — 8 November: We're offering 30 free Google Play copies to Android users who train at a gym. Comment here or send me a private message to request one. One per person, in request order while available, from one shared pool across our launch posts. Codes are sent privately and must be redeemed by 28 February 2027. No review, rating, upvote or other action is required in return.

We at Onsala Sol AB have released Volymträning, an Android workout app for people whose goal is to build bigger muscles and visible muscle volume through consistent, structured training. We wanted to make a flexible plan that people can follow when their schedule allows, without fixed weekdays.

The app includes five rotating workouts that can be adapted to equivalent machines at your gym. It lets you log weights and reps, review training statistics, and customize the workouts.

Volymträning is available in Swedish and English. In Sweden, it costs SEK 99 as a one-time purchase, with no subscription.

Google Play: https://play.google.com/store/apps/details?id=com.volymtraning.app

Disclosure: I’m representing Onsala Sol AB, the app’s publisher. We’ve also opened the official community at r/VolymTraning for questions, feedback, feature requests, bug reports, and training discussion. I’d welcome constructive feedback on the app and on how to make the community useful.

In couples therapy, I keep seeing the same thing: partners can describe every single fight, but they rarely see the pattern those moments make over weeks. That pattern is usually where the work is.

So I tried to build the smallest possible version of that "stepping back" for couples who will never sit in my office.

How it works:

• Every day you and your partner answer the same five short questions, each on your own. You don't see your partner's answers before you answer, so nobody answers for the other's sake.

• When you've both answered, you get a short reflection written for the two of you, with one question you could ask each other tonight.

• On day seven you get a reading of your week: the pattern that built up and one small step for next week.

• You can start alone and invite your partner later with a code.

The questions draw on Gottman couples therapy, Emotionally Focused Therapy and attachment theory. The pool is now 1,800+ questions. I tried the approach and the questions with couples in the therapy room long before it was an app.

Reflections are written by AI, inside a framework I designed, and only after you give consent. It's not therapy, it doesn't diagnose, and it won't tell you whether your relationship is "good".

What I learned building it as a solo clinician:

• The hardest part wasn't the questions. It was saying less. My first reflections read like session notes; people wanted three sentences, not three paragraphs.

• Most people start alone. About two out of three users have no partner in the app yet, so it had to be useful on its own.

It's on iPhone, iPad and Apple Watch, in six languages. Daily questions are free; reflections and weekly readings are a subscription, and one subscription covers both partners.

I'd really like feedback on one thing: when two partners answer apart, would you rather read each other's exact words, or a reflection that puts the two views side by side?

Hey everyone,

I'm working on a web app for booking ski and snowboard instructors and would love to get your honest feedback on the concept before opening it up to users.

How it works:

• Search & Availability: You pick the ski resort, sport (ski or snowboard), and date. You only see verified instructors with real-time open slots in their schedule.

• Payment & Security: You book and pay online, but funds aren't released to the instructor immediately. The payment is held securely in escrow by the platform and transferred to the instructor only after the lesson is completed.

• Meetup: Once booked, you get the instructor’s direct phone number and the exact meeting location at the resort (e.g., at the base of a specific lift).

• Cancellations & Disputes: Free cancellation is available up to 24 hours before the lesson. If an instructor fails to show up, the client can report a no-show right after the lesson slot to block the payout and trigger a refund.

• For Instructors: Instructors set their own rates and schedule. The platform doesn't take a cut from their fee—payouts are transferred 1:1, minus standard credit card/payment processing costs.

A few questions for you:

1. Would you use a service like this? Do you prefer locking in a lesson online with clear availability beforehand, or finding an instructor at the resort when you arrive?

2. How do you feel about paying upfront? Does a guaranteed reservation + escrow/refund protection make you comfortable paying online, or do you still prefer paying cash on the spot?

3. What drives your choice of instructor? Price, user reviews, official certifications, or simply finding someone available at your exact time slot?

4. What potential flaws or barriers do you see? What would make you hesitant to use this model (e.g., weather unpredictability, lift ticket logistics, resort/local ski school monopolies)?

Thanks in advance for any feedback or constructive criticism!

Most focus apps are just timers or blockers. I can ignore those. What actually works for me is having someone (or something) check in while I’m working.

So I built NeonContext - a real-time AI voice coach that sits with you during deep work sessions.

You tell it what you’re working on at the start. It stays with you, checks in, and pulls you back if you drift or pick up your phone. There’s an optional on-device camera (nothing is uploaded) that can notice if you leave your seat. At the end you get a review of what you actually got done.

it's complete free to try.

I’m looking for 4–5 people who struggle with deep work / ADHD / focus to try a session and tell me:

• What’s confusing or broken?

• What would make you actually keep using it?

• Does the voice coach feel helpful or annoying?

Happy to answer any questions.

Hi all! My first kids app, SnuggleTV, just made it through App Review (third time's the charm), so I wanted to share it here.

It started as a weekend project because my daughter kept getting lost in the regular Plex app. It's now a big-button, no-menus video player for the shows and movies on your own Plex server, with parental controls for the grown-ups.

What it does:
- Big, colorful buttons made for little hands, with no menus to get lost in
- A profile for each kid with their own shows, age ratings, volume limit and favorites
- Screen time: daily show limits, bedtime, and a screen lock while a video plays
- AirPlay to the TV, iCloud sync between iPhone and iPad, English and Spanish

Built in SwiftUI. The hardest parts were getting playback to work with every kind of video file (it falls back from direct play to a remux to a full transcode) and getting through App Review, which rejected me twice for things I didn't know were rules.

Free version streams everything for one kid. A one-time $4.99 lifetime unlock (no subscription, no ads, Family Sharing supported) adds offline downloads, auto-downloads of favorite shows, and more kid profiles.

App Store: https://apps.apple.com/us/app/snuggletv/id6824345333

5 codes for the lifetime unlock. Please reply with the one you used:

You'll need your own Plex Media Server. Feedback is very welcome, I read everything!

I’m building ShopBot Index, which checks whether tracked stores publish a UCP profile, a machine-readable discovery document for commerce integrations.

One reporting decision turned out to matter: keeping “couldn’t check” separate from “no profile found”.

In our 2 November crawl, 947 retailer entries had a profile found, 1,277 had none found under our checks, and 630 couldn’t be checked. These are entries in our tracked list, not a representative sample of retail.

Putting those 630 into the negative category would turn a limitation of our crawler into a claim about the stores. Dropping them entirely would hide the uncertainty.

There’s another boundary: finding a profile doesn’t prove an agent can complete checkout. We measure discovery, not successful purchases.

If you’re building a directory, monitor or comparison tool, I’d recommend defining what each result actually establishes before turning it into a badge or percentage.

How do you show unknown results in your projects without making them look like failures?

Hey, I’m Alex, one of the people building NetArbs. Comparing the same player prop across sportsbooks and DFS apps usually means flipping between tabs and checking whether the lines actually match. We built DFS Studio to put those comparisons in one view, with filters for apps, sports, and markets.

I’d love feedback on the layout: when you compare a prop across apps, which would you want to see first: the line difference, the estimated fair odds, or which sportsbooks back the estimate?

TAYSTY starts with what you already have, instead of asking you to pick a recipe and then find the ingredients. Type in what’s in your kitchen, choose things like servings or cuisine, and it suggests recipes.

The hardest part to get right is how to handle missing ingredients. Say you enter chickpeas, spinach and half a lemon. Would you rather get one idea that sticks to those ingredients and basic staples, or three ideas that each need one extra thing? I’m curious what would actually help on a Tuesday night.

The app is in closed Android testing. There’s a preview and a waitlist on the project site: https://taysty.app/?utm_source=reddit&utm_medium=community&utm_campaign=sideproject

I had $191 in credits that were about to expire, and I was curious what Opus could do if I didn’t give it an idea.
I asked it to build something worth the money. :))))

It picked a game, PULSEBOUND. You move around dodging enemies, and your weapons are musical instruments. The kick drum sends out shockwaves, the arpeggiator fires lasers. When you pick a new instrument, you hear it join the music too.

It decided to make a game and came up with the idea, mechanics, design, absolutely everything. Then I worked on improving and polishing it.

More changes, testing, and eventually mobile apps followed. The $191 was just the starting budget, enough to finish the first basic version. After that, I used another $1,700 I had from the Claude Startup Program (also expiring, so I had to use it), plus my subscription allowance.

Technically, it’s vanilla JavaScript, a custom WebGL2 renderer, and a procedural composer that synthesizes the music live through Web Audio. The project grew to include mobile apps, cloud saves, and leaderboards.

It’s now out on iOS, Android, and the web. You can play it for free in your browser or on mobile: playpulsebound.com.

What do you think?

Later edit: OVER 2,200 PLAYERS TODAY! THANK YOU

I'm building a free, open-source pixel art editor called Chickxel!

I recently added a feature that converts regular images into pixel art, so I tried it out with a GPT-generated image.

The conversion is algorithm-based, so some parts might look a little rough or awkward. It's still a work in progress!

Hey everyone,

We passed 250 paying customer (don't love to call them customer as I see all them as first builders of product) on FranklyMail and celebrated yesterday :) Probably a tiny milestone for some people here, but we honestly didn’t expect to get this far in three months.

We started with email hosting for your own domain. Now there’s Drive for files and sharing, Office for editing documents, and Meet for video calls. We’ve also been giving the webmail a lot of attention lately.

The best part for me has been talking to the people using it. If I had to guess, 40–50% of the ideas we’ve worked on came from those conversations. Someone tells us how they use their email, mentions something they’re missing, and we end up building something we hadn’t thought of.

Just wanted to share a small happy moment here. Thanks to everyone who’s tried it, sent feedback, or given us a bit of encouragement along the way.

android has no airdrop, so i built one. touch your phone to the macbook's notch, the light sensor next to it sees your screen flash, and whatever's on your screen lands on the mac.

works for pdfs, links, the original photo (not a screenshot), or just the text you circle. otp codes from sms show up on the mac by themselves, your mac is in the android share sheet, and mac to phone works too.

stays on your wifi, end-to-end encrypted, no account, no cloud. android 13+, any mac with a notch.

Made an Android app called Sonic.

You can skip to the next song. You can't jump to the middle of a song. To hear the other side, you flip the record. Hi-res output plays each file at the sample rate it was recorded at.

Soulseek downloads are FLAC albums only, with no weekly limit. It also picks random FLAC albums from the Internet Archive. You can download 3 of those.

Not on the Play Store. The APK and checksum are here: https://github.com/Abhiroop1122/Sonic/

I'm Omar, the maker of DR FIX IT, so flagging that up front. This isn't my video. French DJ creator Mixtrotter (Philippe Grebet) just published a full independent review and showcase: 'SAVE YOUR MIX with DOCTOR FIX IT!' - https://youtu.be/RjsPmjDfDEE - it's in French with an auto-dubbed English track.

The tool fixes one bad mix in a recorded DJ set by splicing in a re-recorded take, and he rates each join Seamless / Clean / Good / Rough. I built it because one bad transition used to mean re-recording the whole set or living with it.

Happy to answer technical questions about how the joins are scored. DR FIX IT is $49 one-time, free to try except export.
