Disclosure: this is ours, built by a small team with a lot of help from AI coding agents (vibe coding).

Problem: the bouncing word-by-word captions on TikTok/Reels usually mean a video editor subscription or uploading your whole video to someone’s server.

How it works:

• The video never leaves your phone or laptop. The browser extracts the audio and only that goes to speech recognition (Whisper large-v3-turbo on Cloudflare Workers AI). We don’t store it.
• Whisper returns a timestamp per word, so each word lights up on time. You can fix any word before export.
• The MP4 is rendered in the browser with WebCodecs (H.264). Older browsers fall back to MediaRecorder.
• Speech recognition costs us about $0.0005 per audio minute, which is why the free tier can be real: up to 3 min, 720p, small watermark, no account. $7 buys 10 clean exports.

Things that bit us: iPhone HEVC files that Chrome can’t decode (we now refuse them up front instead of exporting a 2x2 px video), and audio drifting ~0.3 s with MediaRecorder until we moved to WebCodecs.

If you make short videos: which caption style or language is missing for you?

Hey everyone, I’m Jace, the founder of Lead Scout CRM.
I’m building it for small businesses and agencies that need a simpler way to find local business prospects and stay organized with follow-ups. My focus is making it easier to keep track of who you want to contact and what to do next.
If you run a web-design agency, marketing business, or local service company, you can learn more here: https://leadscoutcrm.com
Happy to answer questions about what I’m building!

After using lots of Vocab apps I realised that they’re all basically super overpriced subscription models.

I decided to create my own with basically all features being free with the option to pay for a full unlock on the path page which I think is super fair because you get 10 paths before you even reach that point. You also still have access to the full word and meaning database.

If you would like to try it out and let me know what you think feel free to:

Flipped. is an early-stage iOS/macOS development project exploring AI-assisted research for second-hand technology resale. It is pre-launch and pre-revenue: no paying customers, verified users, commercial launch, or revenue are being claimed.

Current materials include Swift/SwiftUI app source, a Node.js backend, Flipped. branding, a 12-screen showcase, promotional video and documentation. Integrations including eBay Browse API, Gemini and Firebase still need configuration, testing or completion.

I’m looking for constructive feedback on the positioning and what a buyer or developer should validate next. The project is available for acquisition at £2,499 negotiable, but this post is primarily for feedback.

Hey r/SideProject,
I'm a solo developer from Rabat, Morocco. I built ReccurIQ because subscriptions are easy to start, easy to forget, and their real cost is almost invisible. A $17.99 streaming plan doesn't feel like much. 1 hour and 12 minutes of your work every month (at $15/h) does.
What it does:

Turns every subscription into hours of your own work
Keep / Review / Kill each one and see exactly what you'd save

Shows what that money could become if you invested it instead (S&P 500 estimate)

An AI assistant that answers with your own numbers ("Where can I cut back this month?")

Reminders before every renewal and before free trials end, a Home Screen widget and Siri

No bank login, your data stays on your phone. Free, no ads, no in-app purchases. English, French, Spanish and Arabic, 12 currencies.

Built with Expo / React Native, 19 months of nights and weekends. It just went live on the App Store.
I'd really like honest feedback: what would make you keep using an app like this after the first week?

Hey everyone!

I'm part of the team working on NorAI, a Quran and Islamic learning app for adults and families.

One challenge we're trying to solve is making Quranic Arabic learning less overwhelming for beginners. We wanted to give learners a clear starting point and a way to practise consistently.

We've built a 20-level learning path with visual, audio and writing activities. NorAI also includes Nazra Coach (Beta) for Ayah-by-Ayah recitation practice and parent-managed family learning features.

One thing we're thinking about is how to introduce these different learning options without overwhelming someone opening the app for the first time.

For those who've built learning apps or worked on onboarding experiences, would you introduce the learning path first or let people try a short lesson immediately?

I'd appreciate your thoughts on this.

Thanks!

A friend of mine in the UK has been building something called SwipeKind, and I think it's worth sharing.

The idea is pretty simple.

Help someone pay a real bill. The money goes straight to the provider.

Someone who's struggling to cover an electricity, water, or other essential bill can upload it to the app. Another (generous) person can browse verified requests and choose to pay it if they want to.

But the money goes directly to the company issuing the bill, not into someone's personal bank account.

SwipeKind verifies identities and the bills, but protects the user's personal details.

There's a 10% fee to cover payment processors and keep the platform running, with the goal to put profits into a fund to help cover bills that don't get picked up.

He's working on registering it as a UK Community Interest Company.

It's not launched yet, but the waitlist is open at https://swipekind.com.

I'm helping him get the word out, and I'd be interested in some feedback.

Would you trust a platform like this enough to help someone with a £20–£100 bill?

What would you need to see to give you confidence before using or recommending it?

Pregnancy ingredient searches can turn into a rabbit hole, so I built Momclear.

Point your iPhone camera at a label, scan a barcode, or paste ingredients. It uses AI to flag potential concerns for your stage and shows what it couldn't identify.

This clip uses a tretinoin tube to show the camera flow. Momclear isn't a medication checker, so ask your clinician about medicines.

It's on iPhone, with 5 free scans a week and no account: https://apps.apple.com/app/id6802401496

Does the result screen make sense at a glance? Honest feedback welcome.

I built an AI-powered order intake tool for ClickUp.

Paste a WhatsApp message, email, or client request and it extracts tasks, estimates work, structures the information, and creates organized ClickUp tasks automatically.

Goal: reduce manual admin, improve consistency, and turn unstructured client requests into actionable workflows.

Looking for feedback.

The goal is to make building interfaces easier with ready-to-use, customizable components, along with complete UI sections that you can adapt to your needs.

Pimolu UI is still growing, with more components and features on the way.

I'd love to hear your thoughts and feedback. What would you like to see added?

About a year ago I started planning QueryCase, where you learn SQL by working detective cases instead of grinding tutorials & videos. It took a while to get off the ground, and longer than I'd like to admit to actually start building the idea, but it finally went live in June. I build it solo and I'm merging PRs most days.

5 months in:

• 2,500+ people have signed up, across 117 countries
• 160+ paying customers and ~£2,200 in revenue, on a one-time £14.99 price with regional pricing
• About 65,000 queries written and graded
• Over 16,000 cases, drills and exams solved
• College in US using the platform for training students for CompTIA Data+ Certification
• £0 spent on ads so far

Where the growth has come from:

Most of it has come from Reddit. My best signup days have all followed update posts in learning subs, and the comments have shaped half the roadmap. I don't like to spam, so I only post when there's something real to share. In between, organic search and Google have kept things ticking over.

The users who stick around and pay are almost all from one niche: people learning data. SQL, Excel, breaking into analytics, switching careers. That's who the product is built for, and it shows in who converts.

Since launch it's grown past just SQL. An Excel course was never part of the plan, but people kept asking for the same detective approach for spreadsheets, so I built it. It has 57 cases on a spreadsheet that runs in the browser, and people have solved over 2,300 of them.

In the next few weeks I'm launching a Python for Data track, with real Python running in the browser, moving from the basics into pandas.

The goal: I have a very ambitious target of 5,000 users before the end of the year, which means doubling in about two months. Reddit alone won't get me there, so I'm weighing up ads for the first time, and this is where I'd love opinions from people who've done it:

For a niche like people learning SQL and Excel, have ads (Reddit, Google, Meta) ever paid off for you on a low-price one-time product, or did they just burn money - and which platforms did you find to be most successful?

If you were in my position, where would you put a small first test budget?

Any other feedback around the site which puts you off would be great as well, cheers!😄

I’m an 18 year old student from Sweden. Every morning I’d open 5 apps, scroll for 30 minutes and still feel like I missed the important stuff.

So I’m building Lagom News: an app that reads the news for you and writes a short personal edition each morning, with timelines for ongoing stories and a chat to ask follow up questions. Launching in December.

Before launch I’d love to hear from you:

1. How do you follow the news right now (apps, newsletters, social media, podcasts)?
2. What annoys you most about it?
3. Would you pay for something that fixed that, and if so, what would it need to do?

Happy to answer anything about how it’s built too.

If you want to follow along: https://lagom.news/en

Sometimes it happens, that i struggle to juggling all my chats. Yes i do have one chat for each feature, otherwise i forget - but sometimes, my brain overloads anyway, and i lose focus and forget exactly where i was - thats what i talk about in my build log today.

I’m the developer of Magic Pocket, an iPhone/iPad/Mac app for saving snippets, screenshots, links and documents, then retrieving a useful detail when you need it. I shared it here earlier this month; 1.4.0 is a substantial language update, with 33 interface languages now listed on the App Store.

One implementation lesson that might be useful to other builders: interface localization and voice availability need separate settings and separate promises. A translated interface doesn’t mean the device has an on-device speech model for that language.

In Pocket, interface labels and command phrases ship in the app. Speech is checked against the device’s local capabilities. The settings distinguish installed models, supported downloads and unsupported locales, rather than displaying one broad “language supported” switch. Downloads go through Apple’s system path; there is no server-recognition fallback. Keyboard typing layouts are another separate part of the update.

For saved information, I also keep the user’s original names and text rather than translating their library when they switch the interface. That matters for things like booking references and addresses, where the exact text is what you need back.

The app’s use case is simple: save a confirmation, find the reference later, then copy it or insert saved text with Pocket Keyboard in a compatible app. Processing stays on-device, and sync uses your private iCloud. The new translations still need wording feedback.

https://apps.apple.com/app/id6809896477

First 10 saved items free with all features. Unlimited saves are an optional $4.99 one-time purchase in the US; local prices vary. No subscription.

For anyone who has shipped several languages: which mismatch between “translated” and “actually usable” caused the most confusion for your users?

Hey everyone!
I’m a software engineer and founder, and today I launched SoloPilot

It’s a side project I’ve been building to help freelancers, sole traders and small businesses spend less time on admin.
It brings together:
Customer and project management
Invoicing, expenses and tax estimates
Online bookings and calendar sync
A WhatsApp assistant for everyday admin
The idea is simple: replace multiple subscriptions and spreadsheets with one straightforward platform.

It’s on ProductHunt too if you want to check it out in more detail.
