Eightify alternatives, ranked by what they can read.

The free swap for the core job. Paste a YouTube URL, get a summary, ask follow-up questions in plain language. No install, no extension permissions, and no unpublished price to discover later.

It handles long videos comfortably and its follow-up conversation is far better than Eightify's fixed key-ideas format when you want to interrogate an argument instead of skimming it.

What you lose is the in-page workflow. Eightify appears beside the video; Gemini means copying a URL into another tab. And it does not read comments at all.

The upgrade path if key ideas were never quite enough. Same starting point, a YouTube video, but the output is notes, flashcards and quizzes, and the same pipeline takes PDFs, DOCX, PowerPoints and audio.

Pro is $9/mo and publishes its limits openly, which is a contrast worth naming on this page: 1,000 Basic Quotas and 100 Premium Credits monthly, 5 videos processed at once, 2 channels, 120-minute ceiling on videos without subtitles.

No comment data, and the credit system takes a week to develop intuition for. Channel summarization exists but caps low.

A heavier tool for a different moment. Eightify is for deciding whether to watch; NotebookLM is for after you have gathered several sources and want to reason across them.

Free, tightly grounded, and its citations point back into the source you supplied. The audio overview is a real feature, not a gimmick.

Sources go in one at a time against a per-notebook cap, which makes it the opposite of an impulse tool. It does not read comments.

Also an extension, also on the video page, but inverted: Glasp expects you to pick the passages worth keeping instead of handing you a summary.

It works across the whole web, not just YouTube, and the social layer showing what others highlighted on the same source has no equivalent in Eightify. Prices rose on 1 May 2026 to $15/mo Pro and $36/mo Unlimited, with the free tier unchanged.

If Eightify's appeal was that it did the work for you, this will feel like a downgrade. If Eightify's summaries always felt slightly generic, your own highlights will not.

Already open in a tab for most people, and better than Eightify at answering a specific question about a video instead of summarizing all of it.

One failure mode to know. When it cannot retrieve a transcript it will sometimes produce a confident summary built from the title, description and what it already knows about the creator. It reads exactly like a real summary. Eightify either has the transcript or tells you it does not.

Check one specific claim against the video before relying on anything it gives you.

Solves the thing Eightify never tried to: keeping the summaries. Each saved video is summarized and linked into a growing graph of everything else you have saved.

If you have ever summarized a video with Eightify, closed the tab, and then wanted that summary back three weeks later, this is the fix.

Slower to pay off. The library is worth something in month three, not on day one. Pricing is corroborated rather than read at source.
