Evaluate your speech AI

Private human evaluations of your speech models. Studies are created through the API; this is where you get a key, watch what it costs, and read the results.

Signing in creates your account if you do not have one. New accounts start with $25.00 of credit.

What you get

An API key, and a balance that drains as real people answer. Create a study from your terminal:

curl -sX POST https://api.woodstitch.com/v1/evals \
  -H "Authorization: Bearer $WOODSTITCH_KEY" \
  -H "Content-Type: application/json" \
  -d '{"clips": [...], "template": "tts_detect.v1"}'
