Glasp alternatives, split by who does the reading.

The direct swap, and after the May 2026 rise it is also the cheaper one. Full Readwise is $9.99/mo billed annually against Glasp Pro's $15/mo, with Lite at $5.59/mo if you only want the daily review and the library.

It is the more mature product on the core loop: spaced-repetition review of your highlights, sync from Kindle, articles, podcasts and PDFs, and exports into Notion and Obsidian that actually hold up. Reader, its read-later app, comes with the full tier.

What you lose is the part of Glasp that is genuinely unlike anything else: seeing what other people highlighted on the same page. Readwise is a private tool. If the social layer is why you used Glasp, nothing here replaces it.

A different answer to the same underlying question: how do I get back to what mattered in something I read? Glasp says highlight it; NotebookLM says drop the whole source in and ask.

For a set of sources you can enumerate (six papers, a few videos, some notes) this is strictly less work than highlighting and it is free. Grounding is tight and citations point back into your source.

The ceiling is the per-notebook source cap and the manual, one-at-a-time ingestion. It also has no persistent library across notebooks in the way Glasp accumulates highlights over years, and it never reads comments.

The closest thing to Glasp's philosophy without the manual highlighting. You save a source, it summarizes it, and it links the result into a growing graph of everything else you saved.

That automatic linking is the feature Glasp users tend to miss once they try it: connections you did not make yourself, surfaced later. The tradeoff is that summaries are the tool's words, not yours, and some people highlight precisely because they want their own phrasing back.

Pricing is corroborated from third-party trackers, not read at source, so treat the $10 figure as approximate.

For video specifically, this inverts Glasp: instead of you highlighting a video, it summarizes the video and hands you notes, flashcards and a quiz. Pro is $9/mo, below Glasp Pro's $15.

It also handles PDFs, DOCX, PowerPoints and audio through the same pipeline, which is more input breadth than Glasp offers at any tier. Channel summarization exists but caps at 2 channels on Pro, 10 on Unlimited, 20 on Max.

The metering is the thing to check before switching. Basic Quotas and Premium Credits cover different work, and Pro's 100 Premium Credits per month go faster than you would expect on transcription-heavy tasks.

Only relevant if your Glasp usage was mostly YouTube. It sits in a browser extension next to the video, gives you key ideas and timestamped navigation, and is one of two tools here that reads comments. Its "Top Comment Overview" shows viewer reaction to the video in front of you.

eightify.app/pricing returned 404 on 21 August 2026, so you cannot compare cost against Glasp without installing first. Third-party figures exist and disagree with each other.

The build-it-yourself answer, and the only one on this list where your highlights are plain files on your own disk. The official Web Clipper captures pages and selections into your vault.

Free for personal use, no per-seat subscription, and nothing to lose access to if a vendor pauses its deployment or raises prices, a real consideration given that this list started because of a price rise.

The cost is time. There is no daily review out of the box, no automatic sync from Kindle or podcasts, and the good setups people show off represent hours of configuration. Choose this if that sounds fun and not tedious.
