One POST, one piece of evidence

Get an API key

One POST to /search. Every hit carries evidence your agent can verify and cite: what was found, where, and at which second.

One line of work, three steps

Search & Cite works today. Visual memory and whole-video analysis are on the roadmap, delivered in the same clip structure.

01Available now

Search & Cite

Ask in plain words and get the moment it happened — with the quote, the source, and a timestamp you or your agent can verify.

02On the roadmap

Scene Understanding

Visual memory reads what is on screen — places, objects, and actions — so a query can land on a scene even when nobody said the words.

03On the roadmap

Analyze

Ask about a whole video and get an answer, chapters, and an overview — every sentence pointing back to the second it came from.
