AI detector

Find the sentences that sound like AI

Paste a draft and get a 0–100 AI-likelihood score with a per-sentence heatmap showing exactly where it reads machine-written. Then rewrite the flagged sentences until the whole draft sounds human.

How it works

  1. 1. Scan

    Paste text or upload a file. Every sentence gets its own AI-likelihood score, rolled up into a document verdict.

  2. 2. See what sounds like AI

    The heatmap marks the sentences that read machine-written, so you fix the actual problem spots instead of guessing.

  3. 3. Rewrite until it sounds human

    The rewriter reworks flagged sentences and rescores the result, so you can see the improvement before you publish.

No black box: read how the detector scores text, including what the score means and where it can be wrong.

Built for automated content pipelines

If AI drafts your blog posts, product pages, or outreach, the writing is only half the pipeline — the other half is making sure it doesn't read like a template. DraftFilter slots in as the quality gate: score every generated draft, flag the sentences that sound like AI, and rewrite them until the piece sounds human, by hand in the app or automatically through the API.

For developers

The same detector behind the web app, as a JSON API: submit a score job, poll it, and get per-item is_ai scores back. Batch scoring, idempotency keys, and an OpenAPI spec included.
