TinyDetect - AI text & image detection that runs in your browser
by•
Paste some text or upload an image, and TinyDetect estimates whether it was made by AI. The models run in your browser, so nothing you check is sent to a server. It's free and you don't need an account. Detectors can get things wrong, so treat a high score as a reason to take a closer look.

Hi everyone, I'm Ritabrata and I made TinyDetect.
Most AI detectors ask you to upload whatever you're checking. That's a problem when it's a student essay, a job application or a personal photo, so I wanted to see if the whole check could run on your own computer instead.
I didn't train the detectors myself. TinyDetect uses two existing open models: Fakespot's RoBERTa model for text and the Community Forensics model for images. My work was making them small enough to load in a browser. The text model went from about 500 MB to 97 MB, and the image model is about 26 MB. Both run with ONNX Runtime Web, which uses your GPU if your browser supports it.
Nothing you paste or upload leaves your browser. The page still has to download the models, the runtime and a few fonts, so the first visit takes a while. After that everything is cached, and a text check takes about 60 milliseconds on my laptop.
A few things to keep in mind:
- Detectors make mistakes, so please don't use a score to fail a student or turn down a job candidate.
- Short text, heavily edited writing, screenshots and cropped images are harder to judge.
- Phones may have trouble loading the models.
- Right now the web checker is the only part that's live. The browser extension, Gmail and Docs add-ons and SDK on the site are still in the works.
I'd really like to hear where it gets things wrong, and whether checking things locally would help in your work.
