GlenSum turns any web page, article or PDF into a clean summary in seconds. Bring your own AI key for unlimited use — or start free with built-in models. Pay once, use forever.
Free plan available. No account required to start. Works on Chrome & Edge.
A focused toolkit for people who read a lot on the web.
One click on any article, documentation page or blog post — get the key points without the noise.
Select text on any page and refine, condense or restructure it — great for papers, reports and long reads.
Parse and summarise PDF documents directly, including local files — no upload to third-party services.
Queue multiple pages or documents and let GlenSum work through them while you do something else.
Read the summary in two languages at once — ideal for non-native articles and research.
Send results to Markdown for Obsidian, or as mind maps. Your notes stay in your tools, not in ours.
Three steps. No account, no credit card for the free plan.
Install GlenSum from the Chrome Web Store or the Edge Add-ons Store.
Start instantly with the built-in free model, or paste your own API key (OpenAI, DeepSeek or any OpenAI-compatible endpoint) for unlimited use. The first-run guide walks you through it.
Click the GlenSum icon, open the side panel, and hit Summarize. Every page, article or YouTube video you visit can become a clean summary in seconds.
GlenSum does not run AI on our servers. You connect your own AI provider (OpenAI-compatible API key) or use the free built-in model options, so there are no usage quotas from us and no per-summary charges. Ever.
Popular AI assistants rent you their summary. GlenSum sells you the tool — once.

Pay once. Yours forever, including updates.
Prices in USD. One-time payment — nothing renews, nothing to cancel. Payments are processed by Creem.io as our Merchant of Record. See our Terms of Service for licence and refund details.
Short answers. If yours is not here, just email us.
No. Pro is a one-time purchase. You pay once and keep access to the full version, including future updates. There is nothing to cancel and nothing renews.
GlenSum does not include a paid AI service. You either enter an API key from an AI provider you already use, or use the free built-in model options. This is why we can offer unlimited use without a subscription — the AI usage is between you and your provider.
No. Page content is sent directly from your browser to the AI provider you configured. Our server never receives the pages you read or the text you refine — it only handles licence activation. See our Privacy Policy.
Your activation code is emailed to you right after purchase. Open the extension settings, paste the code, and Pro unlocks. There is no account to create.
Email us and tell us what went wrong. If Pro did not do what you expected, or you were charged in error, we will make it right — including a refund where that is the right outcome. Refunds are issued through Creem to your original payment method. See our Terms of Service.
