Chrome extension
Prathom Workbench
The Prathom tools, one keystroke away. Workbench works out what you are trying to do and puts the right tool in front of you — and runs the text ones in a side panel, without uploading anything.
What it does
Finds the tool, so you stop searching
Type a keyword in the address bar, or right-click a page, and Workbench works out what you are trying to do and puts the right Prathom tool in front of you.
41 tools run in the side panel
Format JSON, decode a JWT or Base64, hash with SHA-256, read a cron expression, work out a tip or a loan payment — in a panel beside the page, without opening a tab or uploading anything.
Nothing is uploaded
The panel tools run inside your browser. There is no account, and a sensitive-site denylist keeps the extension out of the way where it does not belong.
It remembers what you just ran
Re-open a previous run and its text and mode come back. History lives in session memory and is gone when the browser closes — a decoder should not become an on-disk record of what you decoded.
What it does not do
It does not ask for an account, because there is not one. It does not read pages you have not asked it to act on — it requests access to the tab only when you invoke it, and it keeps out of sensitive sites entirely. The tools that run in the panel run in your browser, so the text you paste into a Base64 decoder is not sent anywhere, including to us. What you ran is remembered until the browser closes, and then it is gone.
Everything on prathom.ai stays free and works without it.
