GlenSum - Web Summary Assistant

One-click AI summaries for pages, articles and YouTube. Mind maps, bilingual reading, Markdown and PDF export. Privacy-first BYOK.

GlenSum turns any long webpage, YouTube video or PDF into a clean, structured summary — in one click. ■ HOW IT WORKS 1. Open the article, documentation page or YouTube video you are reading. 2. Press Alt+S (or click the GlenSum icon) to open the side panel. 3. GlenSum extracts the main content and asks your AI model to summarize it. 4. Read the key points, ask follow-up questions, export the result. ■ KEY FEATURES • One-click summaries — web pages, YouTube videos (title, description, captions) and local PDF files • Three length presets — Brief, Standard or Detailed • Follow-up chat — ask questions about the page without leaving it • Mind map export — turn any summary into a PNG mind map • Export anywhere — Markdown, plain text, high-quality PDF, rich text (paste into Notion / Word), Obsidian-ready • Bilingual reading — summarise in your language while quoting the original text • Custom command templates — save your frequent prompts and run them on any page • Batch tab refining — summarise several open tabs and merge them into one report • Reading history — a local dashboard of everything you have summarised • Dark mode and keyboard shortcuts (Alt+S panel, Alt+R regenerate, Alt+D dark mode) ■ BRING YOUR OWN KEY (BYOK) GlenSum works free with your own API key from any OpenAI-compatible provider (ChatAnyWhere, DeepSeek, OpenAI and others). Your key is stored locally in your browser only — it is never sent to us. Pro models (GPT-4o, Claude 3.5 Sonnet, DeepSeek R1) are unlocked with a one-time Pro upgrade. ■ PRIVACY FIRST • No account required, no tracking, no analytics • Page content goes directly from your browser to the AI provider you configured • Payment is handled by Creem (Merchant of Record) — we never see your card details • Privacy policy: https://glenkit.com/privacy.html ■ WHY GLENSUM Most summarisers lock you into a subscription and their own servers.
