Free AI checker with probability scores and sentence-level signals
A 0–100 AI probability score reads the text statistically instead of issuing a blunt verdict.
Individual sentences with strong AI signals are highlighted so you can see exactly what triggered them.
Check up to 10,000 words per run, repeatedly, at no cost and with no paywall on the detailed result.
Paste text or upload a file and get a result in seconds — no account required to run a check.
Read and chat with PDFs right beside ChatGPT, Claude and DeepSeek.
PDFs render directly in the sidebar next to the chat, so your document and the AI conversation are visible at the same time.
Summarize a whole document, translate it, or have passages explained in simpler terms using the AI you are already signed into.
Built-in buttons cover the common actions, and you can edit their prompts to make the AI respond in the format and tone you need.
Ask about charts, scans or regions that cannot be selected by taking a screenshot question instead.
