Without signing in
Every tool works. Results stay available for an hour, then they are deleted.
Signed in
Results keep for 24 hours, your recent tools follow you across devices, and your theme and notifications come along from the rest of OpenVibe.
For developers
Run any tool from code: see the Tools API (OpenAPI). The catalog is public JSON at /api/catalog.json, with a plain-text map at /llms.txt.
Are the tools free?
Yes. Every tool on OpenVibe.Tools is free to use, with fair-use limits per address so the shared servers stay fast for everyone.
Do I need an account?
No. Every tool works without signing in, and anonymous results stay available for an hour. Signed in, results keep for 24 hours and your recent tools follow you across devices.
What happens to the files I upload?
Many tools run in your browser, so the file never leaves your device. The rest process files on OpenVibe's own servers and delete them with their results when they expire: after an hour without an account, after 24 hours with one.
Can I use the tools from my own code?
Yes. Most tools have an API: one POST request per tool, jobs for long work, an OpenAPI document and the openvibe-sdk client for JavaScript.
Is OpenVibe.Tools open source?
Yes. The code is on GitHub under OpenVibers and the site is community-run.
One account works on every site. Open source and community-run.
