Glasp is a highlighter that turns research into a drafting surface. Every passage you keep is stored with its source, author, URL and date, so a later draft starts from material you already saved. You can draft on top of it with ChatGPT or Claude, export to Notion or Obsidian, and publish with the highlights attached. The free plan is not a trial.

Glasp fits writing that has to point back at something you read. Collect, filter, then write with ChatGPT or Claude on your own passages, with each source one click away. Highlighting stays free, with no card and no trial clock, but highlights are public by default. Pro, at $12.50 per month billed yearly or $15 monthly, is what lets you keep a highlight private. Markdown, HTML, CSV, JSON, and the daily Notion sync stay on the free plan.
Collection happens while you read. The writing page says to highlight passages you might use — articles, PDFs, YouTube videos, Kindle books — and tag them as you go. Web and PDF highlights can carry a note. YouTube highlights keep timestamps. Kindle is a first-class source, and notes attach to the exact sentence. Tags and full-text search cover the library. The next step is to search or filter your library by tag, source, or author until the material for one piece sits together. Imports on that page are Kindle, Pocket, Medium, Instapaper, and Readwise. The extension installs on Chrome, Safari, Edge, or Firefox and requires a desktop browser. The docs index also lists iOS and Android apps.
Official documentationDrafting uses your passages as the input, not the open web. The page says to write with ChatGPT or Claude on top of your own passages, and keep the link back to each source so a citation is one click away. The model line on that page is OpenAI GPT plus Anthropic Claude. Before drafting, you can ask a question across everything you have ever saved and get an answer with its sources, so you can see what you already have. Hatch draws passages at random and lets AI find a connection. Quoteshots turn one passage into a shareable image with the source credited. A post can carry the highlights it grew from. The MCP connector lets Claude draft from your own highlights, and the docs index also names ChatGPT for that connector. The writing page does not describe a model picker in the draft box.
Official documentationThe pricing page says highlighting the web, PDFs, YouTube, and Kindle is free and stays free. The free plan has unlimited public highlights, no credit card, and no trial clock. It also includes basic YouTube summaries, PDF uploads and chat, AI chat credits, and 30 minutes of audio transcription a month. Every account on the writing page includes a free monthly AI quota. Paid plans are for two stated reasons: keeping highlights private, and using AI past those monthly limits. Pro adds more chat credits, more PDF chat, longer audio, and the Balanced and Deep models rather than Fast only. Basic YouTube summaries send the transcript and your prompt to ChatGPT, Claude, or Gemini in a new tab: 3 a day on the free extension, with no daily cap on paid plans. Advanced summaries are written beside the video and saved to the account: 3 every 7 days free, 1,000 every 30 days on Pro, and 5,000 on Unlimited, shared with article and PDF summaries.
Official documentationMarkdown, HTML, CSV, and JSON exports, and the daily Notion sync, are on every plan, including the free one. The writing page also names Obsidian. The docs index lists more connectors, including Pocket, Raindrop, Readwise, Hypothesis, and Diigo, without describing their fields. The API reference says developers can programmatically export and create your highlights, bookmarks, and AI summaries, plus export Kindle highlights. Auth is an access token. Highlight Export is listed at 100 requests per minute. Create, update, delete, bookmarks, and summaries are named too.
Official documentationA suggested article session starts in the library. Filter by tag or author, then draft with ChatGPT or Claude on those passages and keep each citation attached. If a section has no saved passage, highlight the source instead of asking the model to supply one. Publishing with the highlights attached is the suggested way for a reader to see the evidence. It is not an article this profile produced.
A suggested video pass chooses the summary type first. Basic summaries open ChatGPT, Claude, or Gemini in a new tab, at 3 a day on the free extension. Advanced summaries stay beside the video and save to the account, at 3 every 7 days on the free plan. Use basic when you want another assistant's tab, and advanced when the note should remain on the account. The pages do not say the two quotas pool.
A suggested handoff uses the free exports: Markdown, HTML, CSV, or JSON, or the daily Notion sync. Obsidian is another named destination. The files themselves do not require Pro. Pro is the suggested upgrade when the set must stay private or the free AI quota is the limit. The 40% student offer is yearly Pro after a short verification, and the discounted amount is not shown.

NavHunt did not run Glasp. No highlight, draft, or checkout was performed. The free-plan rules, the $12.50 and $15 Pro lines, and the YouTube quotas come from the public pricing and writing pages. The API sentence comes from the public reference. Figures that appeared only in a later live render of the pricing grid are not used here. This description is based on Glasp's official materials reviewed on 2026-10-06, including AI Writing from Your Own Research | Glasp, Pricing — Free to Highlight, Pro for More AI | Glasp, Glasp API Document.
The free plan keeps highlights public. Pro is the public switch for privacy and higher AI limits.
