Sage2 by Levanto Labs

Verdict: A developer API that turns text, including a live call transcript as it grows, into typed fields and yes/no, choice or score decisions with a confidence number, so your app can act on what a customer just said.

Fit Developer

Levels show who gets value from it — many tools work for both beginners and experts.

🚀 Getting started: Try the Sage2 playground at playground.levanto.ai, then get an API key at levanto.ai and start with one extract call before trying the WebSocket stream.

✅ Good fit if you build voice or chat agents and need reliable structured answers (agreed or not, amount, date) mid-conversation.

⛔ Not for you if you want a finished no-code app rather than an API to wire into your own software.

The score rates quality; this box tells you whether it suits you. How to read it

API billed by tokens used; free playground to try it · Official site: https://levanto.ai/ · source checked 2026-11-09 (HTTP 200)
