Instead of trapping highlights inside one app, Glasp makes them social. Install the extension, highlight a paragraph on any site or a line in a YouTube transcript, and it lands in your Glasp profile where you can add notes and tags. Because highlights are public by default unless you make them private, a feed of what like-minded people are reading and marking emerges — you can follow other users, see what resonates, and discover sources you would not have found on your own. Your library becomes the raw material for AI features. Glasp can summarize a long article, a PDF or a YouTube video so you can decide whether it deserves reading, and it can organize what you have already saved into themes. The standout feature is the AI clone: by training on your own accumulated highlights and notes, it produces something that answers in the shape of your interests and reading history. There is also a digital-legacy angle, letting you hand your accumulated knowledge to someone else. Glasp is free to start, with paid tiers for heavier use and greater AI capacity. Its real niche is learners, researchers, students and content curators who treat annotation as a public, collaborative practice rather than a private bookmark folder — and who want their saved material to do work for them later instead of gathering dust. **Pricing & Plans:** Freemium. A free tier covers the core highlighting, saving and sharing features with limited AI usage; paid plans add higher AI limits and additional capacity.

It ships as a Chrome extension that sits alongside the YouTube player and as a companion web app where you manage prompts and history. Feed it a video and it returns an overview in seconds, using a model you can select. The standout features go past a single summary. You can summarize specific timestamps to zero in on the moments that matter, save custom prompt templates for recurring research tasks, and fire off inline questions without saving anything. A summary coverage tracker shows how much of the video the model was actually able to process, which adds a useful layer of transparency. The product is popular with students, developers, researchers, content creators and busy professionals who need the gist of a long talk fast. Access is free for basic usage, and users can also unlock pro features with a one-time lifetime membership rather than an ongoing subscription. **Pricing & Plans:** Freemium. Free access covers core features plus a small allotment of diamonds for pro features; a one-time lifetime membership gives unlimited diamonds forever with no monthly fee. - **Instant video summaries:** Get an overview of any YouTube video in about three seconds without watching the whole thing. - **Timestamp-based summarization:** Pull insights from only the sections you care about and skip the rest of a long video. - **Reusable custom prompts:** Create and save knowledge-extraction templates, then reuse them on any video to pull the details you need every time. - **Inline question answering:** Type a one-off question about a video and get an immediate answer drawn from its transcript. - **Transcript search and navigation:** Search the full transcript and click a timestamp to jump to the exact moment, useful for long interviews and lectures. **Strengths:** Very fast summaries, typically a few seconds per video; Free to install and use for basic needs; One-time lifetime option instead of a recurring subscription; Custom and inline prompts turn videos into a research tool **Limitations:** Focused on YouTube only, so other video platforms are not covered; Free tier is limited to a small number of 'diamonds' for pro features; Summary quality depends on transcript availability for the target video [Profile (Markdown)](https://openaitools.app/tool/summifyai.md) ## Frequently Asked Questions ### How do Glasp and SummifyAI compare in monthly traffic?
