Build, deploy, and govern production-ready agentic AI workflows
A visual canvas where retrieval, branching, tool calls, human review, and model steps form a visible, testable execution path you can debug and hand off.
Create agents through chat or manual configuration, give them skills, tools, and knowledge, then ship them as apps, embeds, or reusable nodes inside workflows.
Build repeatable ingestion pipelines for documents, sites, and drives, with extraction, cleaning, chunking, indexing, and retrieval testing before you go live.
Install model providers, tools, data sources, and MCP integrations once and reuse approved plugins across every app in the workspace.

Jump to the exact moment in any video with AI-generated timestamps
Highlight a question or keyword and FasTube returns the moments inside a video where that topic is covered, so you can skip straight to the answer.
Launches from the toolbar or with the Ctrl/Cmd + M keyboard shortcut, appearing as a Chrome side panel that never covers the content you are watching.
Handles videos on other platforms as well as articles and PDFs, so the same timestamp workflow applies almost anywhere you read or watch.
Connect chatbot replies to the underlying source material so an answer written by ChatGPT can be located and verified visually in the original video or page.
