OmniSeek
Give your AI agent the parts of the internet web search doesn't reach.
OmniSeek is an add-on for AI assistants and agents like Claude Code, Cursor, and Codex that lets them search where web search stops.
A real run on 2026-10-11. Asked for Mu Li's words on the Transformer paper's writing, and the minute: web search pointed at the start of his 87-minute video; OmniSeek transcribed all of it and found the line at 1:21:51.
- Web search finds pages about a podcast. Your agent finds the quote, and the minute it was said.
- Web search finds English pages. Your agent also reads the Chinese threads, and answers in English.
- Web search finds a list of papers. Your agent finds the map: what is foundational, what is new.
Quoting podcasts needs one optional add-on.
