YouTube, but you
actuallyown
what you watch.
Take timestamped notes, save vocabulary, and organize videos into your own learning system — free.
Heartbeat timers trigger automatic candidate election across quorum.
Raft guarantees committed entries are durable across majority nodes.
Epoch term fencing prevents stale leaders from writing dirty state.
You watch hours of YouTube.
You remember almost nothing.
Passive watching = no retention
Watching feels productive. But without engagement, your brain files it under "background noise." 48 hours later it's gone. You're rewatching the same thing again.
Notes live everywhere except here
Notion. Apple Notes. Screenshots. Sticky notes. None of them connected to the video, the timestamp, or each other. Your knowledge is scattered and useless.
YouTube's algorithm owns your feed
Your Watch Later has 600 videos. Your saved playlists have no context. YouTube decides what you see next — not you. It's their ecosystem, not yours.
Not a note-taking app.
A learning operating system.
Every feature builds on the others. Notes feed Lexicon. Tags generate Smart Playlists. Spaces organize Channels. Mastery Review turns notes into long-term memory.
Everything you need to
actually learn from YouTube
Not just notes. A full learning system — built around how you actually watch and think.
Timestamped Notes
Every note you type is pinned to the exact second in the video. Come back a month later, click the note — you're right back at that moment. No rewinding. No searching. Just instant context.
Save Words + Meanings
Hear a word you don't know? Save it with its meaning, right inside the video. Build a personal vocabulary list as you watch.
One-Click Curate
See a great video anywhere on YouTube? Add it to your Ubify universe in one click. No copying links. No manual playlists. It's just in — tagged, organized, yours.
Your Own Video Description
Write your own description for any video — what it covers, why you saved it, what to look out for. Future-you will thank you.
Tag Notes → Smart Playlists
Tag any note with topics like #algorithms or #vocabulary. Ubify automatically builds playlists from your tags. Your content, organized the way your brain actually works.
Spaces
Group videos into Spaces — a course, a language, a skill. Keep your learning separated and focused. Like folders, but smarter.
Your Own YouTube Ecosystem
Log into ubify.app and see only the videos you've curated. No algorithm. No recommendations you didn't ask for. No noise. Just your videos, your notes, your knowledge — in a clean personal feed that's actually yours.
A-B Loop
Set a start and end point, loop any segment endlessly. Perfect for tutorials, music practice, language learning — anything where repetition builds skill.
The ultimate YouTube companion
Capture, curate, and dictate directly from YouTube with the Ubify Nexus extension.
Capture & OCR
One-click full screen or selective area snaps. Smart Text Extractor uses local OCR to grab text directly from videos.
Instant Curation
One-click "Curate" button injected into YouTube. Omni-importer detects watch pages. Right-click any link to send to a Space.
Word Capture & Voice Memos
Select 1-3 words on YouTube to save to your Lexicon instantly. Full voice HUD with waveform to dictate notes in 8 languages.
