Why people look beyond Eightify
Eightify is a well-designed tool for one job — compressing YouTube videos into 8 key ideas you can scan in a minute. That job isn't every job.
- No Udemy support. Eightify is YouTube-only. If you take Udemy courses, it simply isn't in the conversation.
- The 8-ideas format is too thin for studying. Great for content triage. Not great when you actually need structured notes to review.
- No retention system. You get summaries, not a way to remember them.
- Subscription-only pricing. No lifetime option, no BYOK.
- No course-aware organization. Each video is a standalone summary.
The seven alternatives
#1 Ravenote Our pick
Why pick it: Only tool in this list that covers both Udemy + YouTube. Full structured notes (not 8 ideas). Spaced-repetition Mastery system. Course-aware organization. Bring your own OpenRouter key for cheap AI inference. $9 once instead of $60/yr.
Watch out for: Longer-form output — not built for 30-second triage. Newer tool than Eightify, smaller installed base. Requires two-minute BYOK setup for the Lifetime plan.
#2 NoteGPT
Why pick it: Widest feature surface — notes, mind maps, flashcards, slide exports. Dedicated Udemy Summary extension. 12M users across their products.
Watch out for: Subscription-only, ~$108/yr. More expensive than Eightify. Feature volume can feel overwhelming if you just want focused study.
#3 Glasp
Why pick it: Broader scope — YouTube summaries + article highlights + social knowledge sharing. 1-2M+ installs. Multi-model AI selection built in.
Watch out for: Knowledge-library shape, not retention shape. No Udemy. Pro pricing going up.
#4 SmarterHumans.ai
Why pick it: Spaced-repetition flashcards linked to video timestamps. Barbara Oakley (Learning How to Learn) is a co-founder — genuine pedagogy credentials. If you want SRS specifically, this is SRS-first.
Watch out for: Flashcard-first, not note-first. Smaller installed base, pricing not publicly detailed.
#5 Slid
Why pick it: Different mental model — screenshot-based note-taking with AI summaries beside the video. Great for visual content (math, whiteboard courses, design tutorials). ~200K installs.
Watch out for: Note + screenshot format is love-it-or-hate-it. Less effective for pure text-based content.
#6 HoverNotes
Why pick it: Saves notes directly to your disk as Markdown, including straight into an Obsidian vault. Perfect if you live in a PKM system.
Watch out for: PKM-first audience. Overkill if you don't already use Obsidian/Logseq/similar.
#7 Video Highlight / Summarize.tech / other single-page summarizers
Why pick it: Dead-simple. Paste a YouTube URL, get a summary. No browser extension needed. Free for casual use.
Watch out for: Manual step every time. No library, no review, no retention. Fine for one-off triage, painful at scale.

Why look for an Eightify alternative?
Common reasons: Eightify is YouTube-only (doesn't work on Udemy), its 8-key-ideas output is too thin if you're actively studying rather than triaging content, it lacks spaced-repetition quizzes, and pricing is subscription-only with no lifetime option.
What's the best Eightify alternative for Udemy users?
Ravenote. It's the only tool here that natively supports both Udemy and YouTube with the same Mastery system and course-aware note organization. Eightify has no Udemy support at all.
Is there an Eightify alternative with spaced repetition?
Yes — Ravenote's Mastery system and SmarterHumans.ai's flashcards both do spaced repetition. Eightify itself doesn't — its 8-ideas format is designed for fast consumption, not retention.
What's the cheapest Eightify alternative?
Ravenote's $9 Lifetime (BYOK) is the cheapest. You pay once, plug in an OpenRouter API key, and pay cents per lecture in inference. Total yearly cost typically stays under $15.
Do any alternatives support full-transcript notes instead of short summaries?
Ravenote, NoteGPT, and HoverNotes all generate notes from the full transcript rather than a distilled 8-idea format. Eightify is specifically tuned for compression, which is exactly what makes it feel too thin when you're actually trying to study.
