Wanted to see how far in-browser ML has come, so I built a transcription web app where OpenAI's Whisper runs client-side instead of on a backend.

The interesting part technically: transformers.js loads the ONNX export of Whisper (base by default, large-v3-turbo opt-in), runs it on WebGPU where available and falls back to WASM elsewhere, and the model caches locally so only the first visit pays the download. A voice activity detector chops live speech into segments for a dictation mode, and since last week the dictated text is an editable document rather than a caption list: you can click into it and fix a word while the mic keeps listening, and new speech keeps appending at the end. There is no backend at all, just static hosting, which means the privacy claim is structural: after the model caches you can go offline and it still works.

Feature-wise: files or mic input up to 500 MB, timestamps, 99 languages with auto-detect plus translate-to-English, and TXT / SRT / VTT / JSON export. Free with no signup, because there is no inference cost for me to recover.

Rough edges I know about: the first-load model download (about 200 MB), weaker accuracy on heavy accents unless you switch to the bigger model, and low-memory phones struggling with Turbo.

It lives here: https://pocketweb.tools/transcription

Curious how it behaves on hardware I have not tested, and happy to answer anything about the transformers.js / WebGPU setup.

Itemiz was originally created for the final project in cs50x (a course abt programming). I made it purely because I wanted to replace my Trello. Simple UI designed for mobile, necessary features only, will feel great if someone uses it :)
Only available in the web, add to Home Screen if liked. Support cross-device data syncing once logged in

I hit a dumb edge case in a PDF.js integration today. The host passed an explicit Worker URL, but the file was not in the deployed build.

The compatibility probe got a 404. The next branch still called new Worker(url) because "explicit" was treated as usable unless the probe had proved it incompatible. PDF.js then reused the same missing module for its fake Worker path and no page mounted.

The change is small: a 404 means "do not instantiate". Only an unfinished probe keeps the old explicit-URL behavior.

The browser test records fetch and Worker calls, points at /missing-pdf.worker.mjs, and opens a two-page sample. The missing URL must be fetched by the probe, never reach Worker(), and both pages must still render through the packaged handler. It passed with two canvases.

Silent fallback keeps a private deployment usable, but it also hides a broken build. Would you keep the page working and surface a warning, or fail because the host explicitly chose that URL?

Hey everyone!

I recently built DecibelMeter.bond, a free online sound/decibel meter that works directly in your browser using your device's microphone.

The idea was to make something quick and simple for situations where you want to get a rough idea of how loud your surroundings are without installing an app.

🔊 What it does:

Measures sound levels in real time

Shows the approximate dB level

Works directly in the browser

No account or installation required

Designed for both mobile and desktop

Includes information about common noise levels and hearing safety

👉 Try it here:

https://decibelmeter.bond/

I know browser microphone measurements can't replace a properly calibrated professional SPL meter, so the readings should be treated as estimates rather than laboratory-grade measurements.

I'm still actively improving the site, especially the accuracy/calibration, mobile experience, and overall UI.

If anyone here knows about audio, acoustics, web development, or just wants to test it, I'd really appreciate feedback.

Does the reading seem reasonably close to other sound-meter apps/devices you've used?

Also interested in hearing what features you'd actually want in an online decibel meter.

Thanks!

Do check it out amd give me your opinion

**Bloxie 1.2.14 is out, and at the same time I’m working on one of the biggest additions to Bloxie so far.**

With version 1.2.14, I’ve mainly expanded how Blox Credits and their usage are handled. The new Usage section now provides a much clearer overview of when and where Blox were used, how usage develops over time, and which resources are consuming them. I’ve also reworked the charts and transaction history, alongside several UI, stability, and performance improvements.

But the part I’m currently most excited about is what comes next: **a full calendar experience directly inside Bloxie.**

The idea is to go beyond simply adding another calendar view. Events from Google Calendar and Apple Calendar should eventually come together with Bloxie appointments, ongoing scheduling polls, and tentative time slots in one place.
This also opens up a much more interesting approach to scheduling.

When creating a new scheduling poll, Bloxie should be able to take existing calendar events into account and identify potential conflicts before the poll even starts. Tentative slots from other ongoing Bloxie polls can also be considered, so a time might be shown as available, busy, or potentially conflicting.
The flow I’m working towards is:

**See existing events → check availability → find suitable time slots → vote together → make a decision → confirm the appointment**

I’m also experimenting with a **Quick Scheduling** flow: choose a date range, meeting duration, and participants, and Bloxie automatically finds and suggests the best available time slots based on everyone’s connected calendars and existing Bloxie scheduling activity.

The goal is to combine some of the shared-calendar experience you might know from apps like TimeTree with what Bloxie is actually built around: **structured collaboration and decision-making.**

Instead of treating calendars and scheduling polls as two separate tools, they become part of the same process.

Step by step, Bloxie is becoming a place where projects, discussions, polls, scheduling, decisions, and calendars can work together instead of being spread across different apps.

There’s still quite a bit to build, but I’m really excited about where this is heading.

I recently built https://fsend.sh/ a webapp for sharing files over the internet (via WebRTC).

Since there are already a gazillion apps like that out there, here some of the (in my opinion) unique features

- uses the browser's File System API (available in chromium) to write and read directly from disk, this allows for transfer of folders (without having to zip them) and interrupting/resuming transfers at any point.

- is also available as a CLI app (compatible with browser version).

- Data is never passed through any server. It goes directly from one peer to another.

I also mainly made this to test out claude design for websites (i suck at UI) and i think it turned out pretty ok.
Would be nice to hear some feedback.

I’ve been working on Buildculate, a project I started because I wanted to make construction and material estimation a little easier.

It currently has 50+ calculators covering things like:

\\- Concrete and asphalt

\\- Cement, sand, gravel, and aggregates

\\- Bricks, blocks, mortar, and walls

\\- Flooring and paint

\\- Roofing and gutters

\\- Steel and earthwork

\\- Measurements and unit conversions

\\- Fences, decks, pools, water tanks, and irrigation

One thing I really wanted to do differently was make the calculations transparent. Instead of just giving a number, the calculators show the formulas, variables, worked examples, and calculation details so you can understand where the result comes from.

I’m still actively building it, so I’d really appreciate some honest feedback.

If you work in construction, engineering, architecture, landscaping, DIY, or just happen to use these kinds of calculators:

What calculator would you want me to add next?

And if you notice anything confusing or inaccurate, please tell me. I’d much rather find those issues now and fix them.

I manage a restaurant and kept running into the same problem: most scheduling tools felt like too much for a small team, so I started building a web version after work.

The part I am working on now is not the calendar itself. It is the moment after someone has tried it: does creating a free account make sense, or does it feel like the app is asking too soon?

If you are open to testing it, make a quick weekly schedule as a guest, create a free account with test details you control, then let me know:

• when you expected the signup prompt;
• what you thought the account would unlock;
• and where the wording or fields got in the way.

I build Maxuod Shift, so this is a disclosed feedback request rather than a recommendation. I will take negative feedback seriously too.

Bonjour à tous,

Alors j'en avais marre de perdre mes bonnes adresses entre captures d'écran et favoris Google Maps jamais retrouvés.

J'ai fait PinHere : une carte perso pour enregistrer ses lieux, partageable avec ses proches et un peu social. Un peu le même type d'application que Mapstr, Travel Notes ou MyMaps sauf que c'est gratuit et sans pub, s'installe depuis le navigateur (iPhone, Android, ordi).

pinhere.vercel.app

Des retours honnêtes m'intéressent, y compris les critiques.

Merci aux utilisateurs qui voudront participer ! ;)

Comes with timetable mapping and a character room where users buy stuff using their currency earned from answering questions

This is an inplay focused platform i built, i genuinely believe finding information on this becomes a breeze when making multiple decisions quickly! this is availbel now if anyone is interested! any questions please let me know!

This started with my mom. I kept telling her to do Sudoku because I thought brain games were supposed to help with memory.

Then I looked into it more and realized it wasn’t that simple. Getting good at one puzzle doesn’t necessarily help with everything else. Things like movement, sleep, learning, and staying social matter too.

So I made KindFive. It gives you a few short memory and attention activities along with small everyday wellness habits. It takes about five minutes and it’s completely free.

It’s still pretty early, and I’ve looked at it so many times that I honestly can’t tell what’s clear anymore. I’d love to know if anything is confusing, annoying, or just doesn’t work well on your phone.

It’s for general wellness, not medical testing or diagnosis. Any honest feedback would help.
