DataHunter

Data tools that run in your browser

Free browser tools: JSON and Markdown editors, QR codes, PDF and video editing, timer, proxy list, encrypted notes and file transfer. No sign-up.

What works right now

Tools that are open to everyone. More are on the way.

Open a PDF, fix a page, trim a video, write a text. Files are processed on your device and never uploaded.

Merge, split, rotate pages and add text — in your browser

Write Markdown and see the result next to it as you type.

Photos, clips and sound into one video — in your browser

Formats, codes and network: format JSON, make a QR code, pick a live proxy for your scraper.

Format, check and fix JSON. Errors are shown with the exact line.

Create custom QR codes for URLs, contacts, WiFi and more.

Live public HTTP and SOCKS5 proxies with country, speed and filters.

Not about files but about you: hold your focus, take a breath, keep a note only you can read, pass a file straight to another browser.

Pomodoro and time tracking: focus, tasks, reports

Box breathing and 4-7-8 with a calm visual rhythm to follow.

Send secret messages that self-destruct. Encrypted end-to-end, nothing is stored on a server.

Send a file straight to another device, with no upload to a server.

An infinite canvas where you explain an idea, with every step recorded and replayed.

Files are neither uploaded nor stored on our servers. Editing happens entirely on your device.

Recent documents are kept in the browser, so you can return to what you were doing.

Open the page and start working. No account, no email, no limits.

DataHunter is growing into a platform for collecting and processing data: webhook capture, social media parsers, storage and a data marketplace.
