Move your team from Glasp to Readwise.
Each person gets a short interview, then a personalized step-by-step guide showing exactly where their saved work, prompts, and projects land in Readwise — and the few things that need a manual step, walked through. You send one invite; nobody becomes the help desk, and nothing in Glasp is changed or cancelled. Want to see where you’re paying for both first? Run the free audit.
Both tools offer an AI layer on top of saved content, but they differ in approach. Glasp's AI Summary button sits in the browser extension and summarizes the current open page or YouTube video on demand; the Chat with Highlights feature lets you query across your entire Glasp library conversationally. Readwise's Ghostreader is embedded inside the Reader app and activates on selected text or whole documents — it answers contextual questions, summarizes sections, and defines vocabulary inline. To move from Glasp AI to Readwise: save content into Reader first via the browser extension, then select text or open Ghostreader from the document toolbar for the same on-demand AI interactions. To move from Readwise to Glasp: install the Glasp extension, open the AI Summary panel on any page, and use Chat with Highlights for cross-library queries. Glasp supports ChatGPT, Claude, Mistral, and Gemini as selectable backends; Readwise Ghostreader uses its own hosted model.
- Warning: Glasp's Chat with Highlights queries across the user's entire saved library; Readwise Ghostreader is document-scoped (one article or document at a time) and does not offer a cross-library AI chat equivalent as of docs reviewed.
- Warning: Readwise Ghostreader requires the Full plan ($9.99/month billed annually); Glasp's AI summary and chat is available on the free tier per docs reviewed.
- Warning: Glasp lets the user choose which AI model powers summaries (ChatGPT, Claude, Mistral, Gemini); Readwise does not expose model selection to end users.
Both tools can pull in highlights from third-party reading apps (Kindle, Pocket, Instapaper, Medium) into a central library. Readwise is the more mature aggregator: connect sources via Settings > Sources (web), and highlights sync automatically on a schedule. Glasp supports imports from the same platforms but the workflow is manual — open the Glasp web app, go to Import, choose the source, and run the import. To migrate from Glasp to Readwise as your aggregation hub: first export all Glasp highlights (Settings > Export > JSON) to archive them, then connect your upstream sources (Kindle, Pocket, Instapaper) directly in Readwise — Readwise will re-pull those highlights natively. To move from Readwise to Glasp: run the Glasp import from the Readwise source to carry your Readwise library into Glasp (Glasp lists Readwise as a supported import source), then connect remaining sources in Glasp.
- Warning: Readwise's automatic sync from Kindle and other sources runs continuously without user action; Glasp imports are triggered manually each time, so high-volume readers will find Readwise less friction for ongoing aggregation.
- Warning: Glasp's Readwise import migrates highlights into Glasp but does not replicate Readwise's spaced-repetition metadata (review counts, scheduling) — those are Readwise-internal and are lost on export.
- Warning: Readwise supports iBooks and Apple Books natively; this source is not listed in Glasp's import docs.
Both Glasp and Readwise export highlights and notes to Obsidian, Notion, and Roam Research. To migrate the integration from Glasp to Readwise: in Readwise go to Settings > Integrations, connect Notion or enable the Obsidian plugin (readwise-obsidian), then set your export folder; once connected, Readwise pushes highlights continuously and automatically rather than requiring a manual trigger. To move from Readwise to Glasp: go to the Glasp web app sidebar, open Integrations, and connect Obsidian or Notion — export is triggered manually or on demand from the extension. When switching, do one bulk export first (Glasp: export JSON/Markdown; Readwise: export via API or the Notion integration) before disabling the old integration so no highlights are lost in the transition.
- Warning: Readwise's note-taking export (Notion, Obsidian, Evernote) is restricted to the Full plan ($9.99/month billed annually); Glasp's integrations with Obsidian, Notion, and Roam are available on its free tier per docs reviewed.
- Warning: Readwise exports are continuous and automatic once configured; Glasp's export is on-demand, so a team relying on automatic daily sync in Obsidian should expect a workflow change when moving to Glasp.
- Warning: Readwise also offers a public API for custom integrations, which Glasp does not mention in its docs — power users building automation (Zapier, Make) should factor this in.
Both products include a mechanism to resurface saved highlights for periodic review. Glasp's Kindle Daily Review imports Kindle highlights and surfaces them in a review session inside the Glasp app; it also treats all imported highlights (from any source) as reviewable. Readwise's Daily Review is the more full-featured implementation: it applies spaced repetition scheduling across all highlights in the library (Kindle, web, Reader, and others), delivers a daily digest by email and in the app, and allows tagging or noting during the review session. To migrate the review habit from Glasp to Readwise: connect your Kindle account in Readwise (Settings > Sources > Kindle), let Readwise pull the same highlights, then enable the Daily Review email. To use Glasp instead: import Readwise highlights into Glasp via the Glasp import flow, then use Glasp's Kindle Daily Review mode for daily sessions.
- Warning: Readwise's spaced repetition scheduling is algorithmic and automatic, adjusting intervals based on recall feedback; Glasp's daily review is a simpler resurfacing queue without evidence of SR algorithm in docs reviewed.
- Warning: Readwise Daily Review is available on both Lite ($5.59/month billed annually) and Full plans; Glasp's review mode is part of the free tier, making Glasp the no-cost option for basic daily highlight resurfacing.
- Warning: Spaced repetition metadata (review counts, intervals) from Readwise is not exportable in a format Glasp can consume — switching away from Readwise resets review history.
Both tools let users capture and annotate YouTube video content via transcripts. Glasp's YouTube Summary Chrome extension shows a transcript panel alongside any YouTube video; users highlight timestamped segments and generate AI summaries on demand. Readwise Reader also pulls in YouTube videos (paste the URL into Reader or use the extension) and displays the transcript for highlighting and annotation in Reader's standard interface. To move from Glasp to Readwise for YouTube: disable or ignore the Glasp YouTube extension panel and paste YouTube URLs into Readwise Reader instead; highlights made in Reader sync back into the Readwise review system like any other content. To move from Readwise to Glasp: install the Glasp extension and use the transcript panel that appears natively on youtube.com. Glasp highlights from YouTube export to Obsidian, Notion, and Roam in Markdown.
- Warning: Readwise Reader requires the Full plan ($9.99/month billed annually) to access YouTube transcript highlighting; Glasp's YouTube extension is free with no sign-in required for basic summaries.
- Warning: Glasp's YouTube Summary extension has 2M+ users and is a standalone Chrome extension; users who only want YouTube summaries without a broader read-it-later workflow would be over-served by switching to Reader.
- Warning: Glasp allows selection of AI model (ChatGPT, Claude, Mistral, Gemini) for video summaries; Readwise Ghostreader does not expose model selection.
Both tools support highlighting text on web pages and PDFs, but through different surfaces. Glasp uses a browser extension that lets you highlight directly on any live webpage; Readwise Reader saves articles first into a read-it-later queue and highlights happen inside the Reader app. To move from Glasp to Readwise: install the Readwise Reader browser extension, then save pages via the extension instead of highlighting in place. To move from Readwise Reader to Glasp: install the Glasp Chrome/Safari extension and highlight pages on the live web. Existing Glasp web highlights can be exported as JSON or CSV from the Glasp web app (Settings > Export) and kept as an archive; Readwise has no direct bulk import for those files, so keep the Glasp export as a historical record.
- Warning: Glasp highlights live on the open web (inline on the original page); Readwise Reader saves a parsed snapshot, so highlights are tied to Reader's cached copy, not the original URL. Pages that are paywalled or JavaScript-heavy may render differently in Reader.
- Warning: Readwise Reader is only available on the Full plan ($9.99/month billed annually); Glasp's web highlighting is free, so switching to Readwise adds a subscription cost.
- Warning: Glasp highlights PDFs opened in the browser natively; Readwise Reader can import PDF files directly but requires uploading the file to Reader rather than annotating a browser-loaded PDF in place.
