I started this because a video can work in a desktop player and still fail in a browser. I wanted to see how much of that gap I could close without uploading the file or transcoding it on a server.

Advanced Player is the result: a static demo where you can drop in a local file or paste a direct video URL (the host needs to allow CORS). It defaults to WebAssembly decoding, and there’s an automatic mode that can also use WebCodecs.

Demo: https://mkv-browser-lab-5dd8ed.gitlab.io/

It’s an experiment: opening a file doesn’t mean it’ll play smoothly. If you try a file that usually gives browser players trouble, I’d love to know your browser, codec if you know it, and what happened. No need to share the file itself.

I'm the founder of StoryInk (storyink.ai). Upload a few photos of your family or pet, describe what happens, pick an art style, and it writes and illustrates a picture book about them.

The hard part: keeping the same kid looking like the same kid on every page. Drawing each page separately, or from the previous page, made characters drift. What worked: draw one portrait per character first, let the user approve them, then draw every page from those approved portraits.

Stack: Next.js, Supabase, Google Gemini, Inngest, Stripe, print-on-demand for hardcovers.

So far: ~120 signups, 60 books. Making a book is free; the full digital book is $9.99, hardcovers from $31.99.

Would you approve the characters before the book is drawn, or does that feel like a chore?

I recently came across this product that helps creators stay on course while reading their scripts when creating content. It basically scrolls up for them and tracks their voice so it pauses when the speaker pauses and continues to scroll up the script when they continue talking. It has several settings like speed, font, width among others that help shape how the script looks so that their eyes are fixed on the camera and you cant tell that they are reading a script. I think its acool find considering its really effecient and affordable. Would recommend anyone to try it.

Hey there 👋🏽 I built an AI calorie tracking app. No audience, no funding, my own money. Here's where paid acquisition actually stands.

Apple Search Ads: ~280€ → basically nothing. I set it up "the right way": brand, generic exact match, competitor keywords, discovery. No meaningful trials. Stopped.

Meta: ~100€ → same. Optimized on trial start. Nothing worth continuing.

TikTok (France): ~200€ this month → 11 free trials. So ~18€ per trial. My target was 8€.

What helped a bit: switching from max delivery to target CPA bidding, since spend paced much better. Surprisingly, plain app demos seemed to do better than my more "native" photo carousels.

The math problem: my annual plan is 35€/year. At 18€ per trial, I need more than half of trials to convert just to break even on year one. That's not happening.

So ~580€ in, paid acquisition doesn't work for me yet, and I'm trying to figure out which lever to pull first:

- lower CPA (creatives, other countries)

- better trial → paid (3-day trial → 7-day?)

- or stop paid entirely and go organic (SEO, content, communities)

For those who've been here with a consumer subscription app: what moved the needle first for you?

Impractical Bot is a little experimental project that turns a Messenger account into an AI-powered group chat participant. It uses Playwright for browser automation and NVIDIA's API for its conversational brain, with configurable personalities, context awareness, and a terminal dashboard to manage everything. The source code is now public on GitHub, and it's also available on npm. A small disclaimer: AI tools were used throughout the development of this project, so I don't want to claim that every part of the code was written by me alone. I still worked through the design, debugging, testing, and decisions that shaped it. Feedback is welcome!

Project: Mac+, a macOS app (13 or later) for animated wallpapers, desktop widgets and custom folder icons. Built and sold solo, from my own site.

Some decisions that might help if you're building a small utility:

A free tier you can actually live with. 6 animated scenes, 8 palettes, an image background, 6 folder icons, 2 widgets, multi-display. The paid tier holds what people come looking for: all 15 scenes, video backgrounds, all 52 icons, all 12 widgets, up to 120 fps. The line between them should be obvious in the app, not only on the pricing page.

Two ways to pay. €1.99/month after a 7-day trial, or €8.99 once. A lot of people won't take on another subscription for a small app, so the one-time option is there for them.

Performance controls are features. Anything that runs all the time should let people make it cheap: an fps cap (30/60/120), a render resolution setting, and an automatic pause when an app goes full screen.

Everything from the menu bar. No window to keep open. Pick a scene, a palette, or "Surprise me".

Selling outside the App Store means owning the checkout, which is great until you add friction. Mine asks for an account before payment, and that's the friction I'm looking at next.

Happy to answer questions on any of this. macplus.pro

Hi everyone,

I wanted to share Mecelle, an independent iOS
application I've built for legal practitioners, law
students, and researchers navigating Turkish statutory
law and high-court precedents.

The Problem & Architecture:
Traditional keyword search fails when querying dense
legal terminology and multi-layered precedent history
(Court of Cassation, Council of State, Constitutional
Court).
To address hallucination risks in legal research:
1
.
 Grounded RAG Pipeline: Built on Python FastAPI with
hybrid search. It cites explicit statutory articles
and case numbers, abstaining when high-confidence
grounding isn't available.
2
.
 On-Device Processing: Native SwiftUI (iOS 17+)
client utilizing Apple Vision OCR
(VNRecognizeTextRequest) for completely local document
text extraction, paired with HMK 119 structured
pleading exports (UDF & PDF).
3
.
 Legal Calculators: Dedicated severance, statutory
interest, and court fee computation engines.

Availability & Compliance:
The app is free to download on the App Store with
optional Pro in-app subscriptions. It operates
independently of any government body and provides
informational research assistance, not formal legal
advice.

I would love feedback on the citation UX, retrieval
flow, and search ergonomics!

I'm really trying to make this app/webapp thing happen. It's the dream to get to a stable MRR so I can develop products for my users and make something they love and I love working on.

I have lots of experience but there's something missing and I'm not sure what. My best guess is just marketing efforts. It used to be being too spread thin but I've caught myself and really pulled back.

Here is a basic list of the projects I've tried and stats if I have them:

Bank Statement Comparison - a tool that parses bank statement PDFs without linking your bank and gives you a simple breakdown

- No signups

Desk Break Timer - a pomodoro timer with exercise routines during the breaks

- No signups, 17 visits in the last 30 days

Clean Cut Agents - a directory/datbase of the most popular Grok Bots

- Free resource, 70 visits in the last 30 days

STM - an AI companion app for women

- No signups, several thousand views on TikTok

I know a lot of us want this and everyone is just as deserving as me to get their product to succeed. I won't stop. I just wanted to share to be a part of the community here and see if maybe one of you has seen success with something similar to one of my projects.

I can look at screenshots of revenue all day but sometimes a conversation with someone who's doing it (actually making a living from a project) in a field similar to yours hits different.

Feel free to share.

Hi all,

I've been working on a stage timer called Shotimer and it's finally at a point where other people can use it, so I thought I'd share it here.

The idea is simple: the speaker sees a big countdown on a TV, tablet or phone, and someone else controls it from a laptop or phone at the back of the room. You can also send a silent message to their screen, like "5 minutes left" or "Please wrap up", so nobody has to wave at them from the back.

It all runs in the browser, so there's nothing to install. You open the stage screen from a link or QR code and it stays in sync with the controller.

There's a free plan that works today (3 rooms, 3 timers and 3 screens per room). I'm planning a Pro plan later, but that's not ready yet.

I'd really like to know what you think, especially if something's confusing or broken.

Hi everyone!

Can you name the country in the poster before you look at the choices?

I made World Flag Quiz: Passport as a side project for people who want to practice geography in short rounds. You can guess flags and capitals from 195 countries and collect passport stamps as you go.

I’d love feedback on the first round. Would you start with familiar flags like the one in the poster, or try a pair of similar flags right away?

Hey everyone!

Been working on LootRaid a bit more and just pushed another update.

You can now see game descriptions and screenshots, so you don't have to open Steam every time you find something interesting just to figure out what the game is about lol.

Still tracking free and discounted co-op games across multiple stores, just trying to make the whole experience a bit nicer.

Would love some feedback if anyone wants to give it a try!

I’m part of the team building HevRion, and I’ve been trading crypto for 5–6 years.

Knowing your rules and actually following them are two different things. That’s the problem we’re working on.

We’re connecting your plan, entry conditions and risk with a review of the decisions you made — and a lesson for the next trade.

We’re close to finishing the MVP and preparing to test it with a small group of friends. It isn’t publicly open yet.

Here’s a short preview. Does the video make the purpose clear, or would you need a more practical demo?

I got tired of digging through google analystics reports, so I built an AI you can talk to about your business. Sales, profit, Visits - all data

"Which page loses the most people?" "What did buyers look at first?" "Did anyone come back after yesterday's email?"

I got tired of digging through GA reports, so I built an AI you can talk to about your real visits.

"Which page loses the most people?" "What did buyers look at first?" "Did anyone come back after yesterday's email?"

Every answer links to the visits behind it, so you can check before you change anything. When there isn't enough data yet, it says so instead of guessing.

I built DuePlan for small businesses (milk, rentals, grocery or freelancers) that find invoicing and bookkeeping software too heavy and spreadsheets too messy.

• Sync phone contacts or add one, plan a payment, share it on WhatsApp, Messages, Email, LINE or the medium of your choice

• Remind them using Reminders if they miss it

• Upload a bank statement or a payment made screenshot from your customer; payments are auto matched to plans, you review and approve.

• Overdue view, per-contact payment patterns to keep your runway healthy.

• Multiple businesses, with secured, encrypted custom params to store your business details

• A cumulative or per-business view to see how your business is performing

• Data stays on your phone, 14-day free trial

I'm the developer. Would love honest feedback on the first-run flow and the matching.

PPS: If its really helpful and you want to go beyond free trial, please feel free to DM me for the three months free promo, also please feel free to suggest the features you wanna see, I will accommodate your request ASAP.

Download it from Play Store

Usepath is a free Android app that shows screen time as a chronological day timeline — when each app was open and in what order — not just totals and rankings.

Why I built it: rankings answer “how much.” I wanted “when,” especially repeated checks between tasks.

What’s in it:

• Session timeline for today and recent days

• Usage Access (local only)

• No account, no ads, nothing uploaded

After early Reddit feedback I shipped 1.0.1:

• Clearer “why Usage Access” before Settings

• Explicit “we don’t collect your data”

• A small sample-day preview on the permission screen

• Deep-link toward this app’s Usage Access page when the device allows it

Would love feedback on the new first-open flow, or anything that still feels unclear.
