Accounts — optional, and what they change
Free, optional, and created in the extension or on the website. What an account unlocks, what it doesn't move, and how to leave.
An account is optional and free. It exists for two things: the study tools that run on our AI keys, and daily limits that follow you instead of your network. Everything CoursifyYT did before accounts existed still works without one.
What signing in changes
| Signed out | Signed in | |
|---|---|---|
| Who the counters belong to | Your IP address — shared with everyone on that connection | You |
| Courses built per week | 2 per IP address | 3 per account |
| AI Overviews per day | 6 per IP address | 8 per account |
| Quizzes, mind maps & flashcards | Own AI key only | Included, up to the per-course allowance |
| Per-course allowances | Counted in this browser, so a new browser starts fresh | Counted on the account, wherever you sign in |
| Where your courses, notes, flashcards & scores live | This browser only — clearing it loses them | This browser, backed up to your account |
| Courses, overviews, transcripts, notes, progress, export | All free | All free |
The quota badge always names which budget it's showing — “on this account” or “on this network” — because the same number means two different things. Every limit, in one table →
What it does not change
Nothing is taken away from this browser. Signing in copies your courses and notes to your account; it never moves or deletes the originals. Signing out leaves everything here exactly as it was.
Nothing that is free today becomes paid. Courses, Overviews, transcripts, notes, clips, screenshots and export stay free with no card, signed out included. There is now a paid plan — CoursifyYT Pro — but it raises limits rather than moving anything behind them, and your own free API key still lifts almost all of them for nothing.
Your own API key still beats it. A key lifts every limit outright and sends your requests straight to your provider. An account and a key are independent — having both is fine.
Creating one
In the extension, open Settings in the panel — or press a study tool that needs an account, which opens the same sheet in place.
Enter an email and a password of at least 10 characters. A passphrase is fine; there are no character-class rules.
We email a 6-digit code, good for 10 minutes. Type it in to finish. If it doesn't arrive, resend after the cooldown, or check spam.
Your courses and notes on every browser
Signing in backs up your courses, watch progress, notes, Actions, saved Ask answers, flashcard schedule and quiz scores to your account and keeps them the same everywhere you sign in. The first sync happens when you sign in; after that, sync runs when you press Sync now — the first thing in Settings, which also says when it last succeeded.
What does not travel: transcripts, Overviews, quiz questions and mind maps — those are generated from the video's captions and cached by video for everyone, not stored against you — and your screenshots, whose images stay on the browser that took them. A screenshot's note still syncs and still says which second it came from, so another browser knows the frame existed and can grab it again.
It merges; it never replaces. Signing in on a second browser
adds
what is there to what the account already has. Whichever version of a note you edited most recently is the one you keep.
Deleting travels. Delete a note or a course on one browser and it goes on the others too — and stays gone.
Your flashcard schedule and your quiz results travel too. When each card is next due, how many times you've forgotten it, and every paper you've been graded on — they're about you rather than about the video, so they follow the account.
Un-ticking a video now travels as well. Progress used to only ever be added together, so un-ticking on one browser came back from another. Whichever browser changed it most recently now wins.
Quizzes, mind maps and transcripts themselves don't sync, and don't need to. They're rebuilt from the video rather than written by you, and we already cache them for everyone, so they come back instantly on a new browser at no cost. Your
scores
are the part that's yours, and those do sync.
What you already used today carries over
Signing in doesn't hand you a fresh day. Whatever you spent anonymously today is counted against the account's allowance, so an account is a higher ceiling, never a second helping. This happens once, on your first sign-in from a given install, and only for the current day.
Your dashboard
coursifyyt.com/dashboard is the other half: /account is what you have right now, /dashboard is how you're doing over time. Everything on it is read back from what the extension synced — it is not a second count, and it collects nothing itself.
To get there: sign in at coursifyyt.com/account. A Your study dashboard card appears at the top of that page, just under your email, and a Dashboard button appears in its header. The dashboard's own header links back to your account.
What you've been doing — videos watched, notes written and quizzes taken, per day for the last 90 days, with your current and best streak.
Quiz accuracy over time, pooled by day across every paper you've been graded on.
What's coming due — the next fortnight of flashcards, with anything overdue counted under today.
Your courses, with how many videos you've watched and how many notes you've taken in each.
What the account page shows
coursifyyt.com/account is the one place your account's numbers are visible:
Today's budget — course builds left, with the count reset time and a badge saying whether it's counting against your account or your network.
Every per-course allowance, read live from the server, so what you see is what's actually being enforced rather than a number baked into the page.
What you've generated — one row per AI study tool you have, and how many courses you've used each on.
Your devices, your data download and account deletion (below).
Your devices
coursifyyt.com/account lists one row per browser you've signed in from — what it is, and when it was last used — with a Revoke button on each. Revoking ends that browser's session immediately; it has to sign in again.
One row per device, not per session. Staying signed in refreshes the same row rather than adding new ones.
Sign out ends only the browser you're using. Revoke is what reaches the others.
Changing your password revokes everything, including sessions already in flight.
Downloading your data
Your account → Download my data gives you a JSON file with everything the account holds: your email, whether it's verified, when it was created, your device list, and your per-course allowance counters. That is the whole of it — the file names what it doesn't contain, and why.
| Not in that file | Why | Where it is |
|---|---|---|
| Notes, transcripts, quiz results, courses | They never leave your browser | Extension Settings → Data → Download all my study data |
| The security log | It's the one place an IP is tied to an account, kept 90 days for exactly that reason and never exported | Nowhere — it expires on its own |
| Your password | We don't have it — only a one-way argon2id hash | Only you |
Forgetting your password
Go to coursifyyt.com/reset — the link is in the extension's sign-in screen and in every code email. Enter your address, we email a code, you choose a new password. Every session everywhere is signed out at that moment, which is the point: if someone else had one, it stops working.
Deleting your account
Your account → Delete account, confirmed by typing your email.
Every session ends immediately and deletion is scheduled, not instant — the page tells you the exact date. Signing in again before then cancels it, with nothing lost.
After that date the account row, its sessions, its security-log entries and its allowance counters are permanently removed.
