Glasp

Glasp is the ultimate FREE highlighter that turns every web page, PDF, or YouTube video into searchable, shareable knowledge in one click. Highlight, add AI summaries, and build your own AI clone that remembers everything for you—no credit card required. Export to Obsidian, Notion, or Markdown, and join a million-user community learning in public. Glasp’s magic is not a single algorithm—it is an orchestration layer that calls the best model for each task:

• ChatGPT (OpenAI) crafts human-like article and video summaries.
• Claude (Anthropic) excels at long-context PDF reasoning—ideal for academic papers.
• Mistral AI supplies lightning-fast abstractive summarization for multilingual content.
• Gemini (Google) enriches YouTube transcripts with timestamped key moments.

When you click “View AI Summary,” Glasp sends the highlighted text plus surrounding context to the optimal model, then surfaces the result in a side-panel that stays in sync across Chrome, Safari, iOS, and Android. Your data is encrypted in transit and stored on GCP with SOC-2-grade security, so even the freemium tier remains enterprise-safe.
