Free Text Tools
Count, convert, format and compare text in your browser. Nothing is uploaded, so confidential drafts and source code stay private.
1 tool ready to use, 7 more planned.
Text tools are the clearest case for doing the work in the browser. Counting words or reformatting JSON needs no server at all — the browser can do it in a fraction of a millisecond. Sites that upload your text anyway are taking a copy of it for no technical reason.
Everything here runs locally, which makes these tools usable for the material you would not normally paste into a random website: unpublished writing, client copy, internal documents, API responses with real keys in them.

What these tools cover
Counting and measuring text, changing its case, formatting and validating JSON, generating placeholder copy, comparing two versions line by line, converting Markdown to HTML, and cleaning up lists by removing duplicate or reversing lines.
Why browser-side text processing is instant
An upload-based tool has to send your text over the network, queue it, process it, and send the result back — typically a second or more, most of it network latency. A browser doing the same string operation locally finishes before the next screen repaint, which is why the counters here update as you type rather than after you press a button.
