Glasp
A social web highlighter with AI summaries of articles and YouTube videos that feeds your highlights into a personal knowledge base.
+ One-click YouTube transcript and summary plus highlight export to Notion, Obsidian and Readwise.
− The social feed and public highlights by default are not what everyone wants, and the AI features feel bolted on.

+ Strong accuracy plus built-in audio intelligence (speaker labels, chapters, PII redaction) and LeMUR for asking questions of a transcript.
− No consumer app, and per-hour pricing adds up on high volumes compared with self-hosted Whisper.
+ Answers are grounded strictly in your uploaded PDFs, Docs, URLs and YouTube videos with citations, and Audio Overviews turn them into a two-host podcast.
− Sources are capped per notebook and the free tier limits daily queries and audio generations.
+ Q&A searches your whole Notion workspace plus Slack and Google Drive, and AI autofill keeps database summaries current.
− Since 2025 the full AI is bundled only into the Business tier, which is a steep jump for small teams.
+ Shows several rewrite options per sentence so you keep authorship instead of accepting one AI version.
− Free plan allows only a handful of rewrites per day.
+ Summaries appear next to the video with timestamped sections, so you can jump straight to the part you care about.
− Free summaries are capped per week and the extension is YouTube-only.
