Work with text, privately.
Paste it in, get the answer — none of it leaves your machine.
Text Diff
Compare two texts — line or word level, side-by-side or unified
Markdown Previewer
Live GitHub-flavored Markdown — tables, code, task lists, footnotes
HTML Entities
Encode / decode HTML entities — named, numeric, hex, emoji
Lorem Ipsum & Fake Data
Placeholder text + fake names, emails, addresses as CSV/JSON
Text in, answer out — no upload
Comparing two config files, checking what changed in a JSON payload, or cleaning up some copy shouldn't mean pasting sensitive text into a server you don't control. These tools run entirely in your browser — the text you paste is processed locally and never sent anywhere. Diff today; markdown preview, HTML-entity encoding, and sample-data generation are landing here next.
