# AI-Text Detection
Estimate the probability that a document's prose was written by AI, with the specific linguistic tells and an honest abstention when the document isn't prose. Uses the Stipple API (free anonymous tier).
## When to use
- Educators screening student submissions
- Publishers and platforms triaging inbound content
- HR reviewing AI-drafted CVs (flag, don't reject)
- Researchers checking source provenance
## Instructions
1. **Get the document.** URL, local file path (PDF, DOCX, TXT, MD), or raw text via `--text`.
2. **Run detection.**
```bash
curl -X POST https://www.stipple.sh/v1/detect-ai-text \
-F "file=@essay.pdf" \
-H "Authorization: Bearer $STIPPLE_API_KEY"
```
For raw text: POST JSON `{"text": "..."}` to the same endpoint.
3. **Interpret the response.**
- `applicable: false` — the document is not prose (forms, tables, scans, spreadsheets). Detection is **deliberately refused** rather than guessed. Report this and stop.
- `probability` — model confidence (0–1), NOT a calibrated truth
- `lean` — "ai" | "human" | "unsure"
- `tells[]` — the specific phrases/patterns flagged (e.g. "It is important to note that", uniform sentence length, low burstiness)
- `reasoning` — why the model reached its verdict
- `limitations` — always present; the API states its own noise profile
4. **Report honestly.** This measures *style, not authenticity*:
