Gist AI

Gist AI is a free Chrome extension that pipes whatever you're reading or watching through ChatGPT and returns a structured summary. It handles long-form web articles, YouTube videos (with clickable timestamps that jump to the source moment), and PDFs - both online and locally stored - without imposing a length cap. The output is broken into discrete blocks and linked back to the underlying passages so you can verify a claim or dig deeper without re-skimming the original.

The pitch is aimed at students, researchers, and analysts who need to triage a lot of input quickly. There's no paid tier, no signup wall, and the developers claim they don't collect user data - content is sent to OpenAI for summarization and nothing else. That makes Gist AI one of the lighter-weight alternatives to bulkier reading assistants like Glasp or Wiseone, though the trade-off is that there's no team workspace, no API, and no real product surface beyond the extension itself.

It sits firmly in the consumer browser-extension tier rather than the enterprise knowledge-management tier. If you want highlights synced to Notion, citation export, or multi-model fallback, you'll outgrow it quickly.
