The short version
Eightify is built for fast consumption. Drop a YouTube link, get an 8-idea summary in seconds, move on. It's the browser-tab triage tool. ~$60 a year, YouTube only.
Ravenote is built for retention. It captures the full transcript, generates structured notes, and then quizzes you on what you watched so you actually remember it a week later. Works on YouTube and Udemy. $9 Lifetime, or $5/mo.
If you watch lots of YouTube and want a quick "what did they say" digest, Eightify is great at that one job. If you're learning something and you want to remember it, Ravenote is the tool for that different job.

The different jobs they do
This is the thing most comparison posts miss. Eightify and Ravenote look similar on the surface — both turn YouTube videos into text output using AI. But they're solving different problems.
Eightify's job is compression. You open a 45-minute podcast episode, realize you don't actually have 45 minutes, and want to know if it's worth your time. Eight bullet points, read in 30 seconds, decide: worth the full watch, worth skipping, worth skimming. It's an aggressive content filter. Brilliantly suited to that use case.
Ravenote's job is retention. You're learning Python, or marketing, or piano, or whatever. You already committed to watching the tutorial. You don't want it distilled — you want notes you can review and a system that tells you what to re-learn before you forget it. Eight bullet points won't help you six weeks later when you need to actually use the knowledge.
These aren't the same problem. Trying to use Eightify for deep learning, or Ravenote for content triage, will feel like the wrong shape for what you need.
Where Eightify is genuinely better
Speed of consumption. Eightify's 8-ideas format is specifically tuned for "tell me if this is worth watching." Ravenote's structured notes are longer and built for later review — not ideal for skim-triage.
Built-in multi-language. Eightify officially supports 40+ languages for both input transcripts and output summaries. Ravenote's multi-language handling depends on the AI model you pick via OpenRouter (most modern models handle 30+ languages, but it's on you to configure).
Brand maturity. Eightify has been around longer and has ~200K installs on the Chrome Web Store. Ravenote is new (launched April 2026). If "number of users" is how you pick software, Eightify has the clear edge today.
Where Ravenote is genuinely better
Works on Udemy. Eightify doesn't touch Udemy. If more than a small fraction of your learning happens there, Eightify simply isn't in the conversation. Ravenote uses the same interface and Mastery system across both platforms.
Retention system, not just summaries. Eightify ends at the summary. Ravenote uses that summary as the starting point for spaced-repetition quizzes. Each concept gets tracked through four mastery levels (New → Learning → Known → Mastered). If your goal is to remember, not just read, this is the entire point.
Pay-once pricing. Eightify subscribers keep paying forever. Ravenote Lifetime at $9 is a one-time payment. Over three years that's $9 for Ravenote vs roughly $180 for Eightify. Three years is a reasonable horizon for software you actually use.
BYOK and model choice. With Ravenote, you pick which AI generates your notes. Want Claude Sonnet for premium quality? Configure it in OpenRouter. Want free open-source models? Also configurable. Eightify picks one model and charges you to use it.
Local-first notes. Ravenote stores notes in your browser, exports to Markdown. Eightify keeps them on their servers. If that matters to you (and for power users it usually does), it matters.
Which user should pick which
Pick Eightify if:
- You watch a lot of YouTube and mostly want to decide what's worth watching
- You need specific support for non-English languages and don't want to configure it yourself
- Deep retention isn't the goal — you just want quick summaries
- You never use Udemy
Pick Ravenote if:
- You're learning from YouTube (or Udemy), not just triaging it
- You want notes plus a retention system, not just summaries
- You'd rather pay $9 once than forever
- You like controlling which AI model generates your content
- You want your notes on your machine, not a company's server
Ravenote is $9 once, then yours forever
Works on Udemy and YouTube. Structured notes + spaced-repetition quizzes. Bring your own AI key, or let us handle it for $5/mo.

Does Eightify work on Udemy?
No. Eightify is YouTube-only. If you're learning from Udemy courses, you'll need a different tool. Ravenote works on both Udemy and YouTube in the same extension.
How much does Eightify cost?
Eightify is roughly $4.99/month after a 7-day free trial, which works out to about $60 per year. There is no lifetime option.
What does Eightify actually produce?
Eightify summarizes a YouTube video into 8 key ideas — a distilled, highlight-reel view of the content. It's designed for fast consumption, not deep study.
Can I replace Eightify with Ravenote?
For most learners on YouTube, yes. Ravenote generates structured notes from the full transcript plus spaced-repetition quizzes. The output is longer-form than Eightify's 8 ideas, but designed for retention rather than skim-reading.
Which is better if I just want quick video summaries?
If speed of summary is the only goal — a 3-minute read of a 60-minute video — Eightify's 8-ideas format is tighter. Ravenote's notes are more comprehensive, which is what you want for courses you're actively learning from, not what you want when triaging content.
