Generate random strings, numbers, UUIDs, and words for test data.
Generate random strings (with your choice of character sets), integers in a range, RFC-4122 v4 UUIDs, and random words — ideal for test data, mock APIs, and placeholder content. Strings use your browser’s secure random source. Runs entirely in your browser.

It uses the browser’s cryptographic random source rather than Math.random, so the values are genuinely unpredictable. That said, anything that will actually protect something — session tokens, API keys, password resets — should be generated server-side where it never crosses a network.
Test data. Filling a database with realistic-looking records, generating sample IDs, stress-testing a form with awkward input lengths, or producing dummy values for a demo. Generating hundreds at once beats inventing them by hand and accidentally creating patterns.
Because target systems have rules. Some fields reject symbols, some accept only alphanumerics, and some are read aloud or typed by hand, where excluding lookalike characters such as l, 1, O and 0 prevents real errors. Matching the constraint upfront avoids generating data your own system rejects.
Yes, Random Text Generator is completely free. No signup, no account, and no watermark on outputs. A Pro tier is available for 100 AI ops/day and larger file sizes.
Random Text Generator runs entirely in your browser. Your file is never uploaded — it is read, processed and saved locally, so it never reaches our servers or anyone else's. You can disconnect from the internet after the page loads and it still works.

Four kinds of data: Random strings (with your choice of character sets), integers in a range, RFC-4122 version-4 UUIDs, and random words — perfect for seeding test databases, mock APIs, and placeholder content.
Randomness: Strings use your browser’s cryptographically secure random source (crypto.getRandomValues) when available. For high-stakes passwords, use a dedicated password manager.
Look-alike exclusion: Optionally drop easily confused characters (O/0, I/l/1) so generated codes are easier to read and type by hand.
Privacy: Everything is generated locally in your browser. Nothing is sent to a server, so it works offline.
