Using Thoth.

No. Recording, editing and exporting all work without one, offline. An account is only for the online extras: help centers, Pro, cloud backup and sync, and teams.

Two ways, and either is fine. Sign in to Thoth with the account that has Pro (Settings → Plan & license → Sign in with Thoth), and Pro turns on with nothing to copy. Or paste a license key into the same page and choose Activate. A key from a purchase is on your account page and in your email.

Three at a time. A license counts the computers it’s active on, so a key (or an account’s license) can be on up to three. On a team, each person who is given a license gets three of their own.

Open your account page at my.usethoth.app and look under Your computers. Remove a computer you no longer use, then try again in Thoth. A computer you haven’t used for 30 days stops counting by itself. If you can’t reach your old computers, contact support and we can free the places.

Yes. A key is checked on your computer, so Pro keeps working without a connection until the key ends. When Thoth is online it checks in about once a day: it picks up a renewed key, and counts the computer. A key from a subscription lasts until your paid period ends plus two weeks. The key an account gives the app lasts about a week and is renewed daily.

A team’s admin gives each person a license on the website (the Team page). Each person signs in to Thoth with their own account and Pro turns on. If the admin takes a license back, or the person leaves the team, Pro ends on their computers within a week.

Install Thoth on the new one and sign in, or paste your key. Then remove the old computer under Your computers on your account page. Your guides don’t travel by themselves: restore a backup, or use cloud backup or sync on Pro.

Pro features turn off once the key runs out (your paid period plus two weeks). Your guides stay on your PC and everything on the Free plan keeps working. Cloud copies and help centers follow the Free plan’s limits.

It’s on your account page at my.usethoth.app. If you were given a key by someone else, ask them for it again, or contact support.

That’s Windows SmartScreen, which warns about installers it hasn’t seen many times and that aren’t signed with a publisher certificate. Thoth isn’t signed yet. Choose More info, then Run anyway. Only do that for a copy downloaded from usethoth.app: its checksum (SHA-512, in base64) is published at downloads.usethoth.app/latest.yml so you can compare.

Thoth watches your clicks in every program, so it knows which control you clicked, and takes screenshots. Some security tools treat that as suspicious, most often for new programs that aren’t signed. It never logs keystrokes or reads password fields. Allow the Thoth program folder and its data folder (%APPDATA%\Thoth) in your security tool. IT teams that need a hash or a vendor submission can ask support.

Windows doesn’t let a normal program see clicks in a program running as administrator. Run Thoth as administrator for those (right-click Thoth, then Run as administrator). Windows’ own secure screens (the sign-in screen and permission prompts) can’t be captured at all.

Some windows block screenshots, such as protected video and a few programs that draw with the graphics card directly. Capture the full screen or draw a region instead of capturing the window.

Another program is probably using the same keys. Change them under Settings → Hotkeys. Ctrl+Alt+R starts and stops by default.

Copy the whole key (it starts with CT1-). If it says it expired or isn’t valid, the key is old or incomplete. If it says the license is already in use on three computers, see the licenses section above. If you were given the key by someone, ask them to check that it hasn’t been revoked.

Thoth tells you why, on Settings → Plan & license. The usual reasons are that the license is already on three computers, or that it was taken back by your team’s admin or revoked. The message names what to do.

It opens your default browser. Check that one is set, and that you choose Connect on the page that opens. If your computer’s security software blocks the short-lived local connection the sign-in comes back to, use Settings → Integrations → Use a token instead: create a token under Help centers on your account page and paste it.

On your PC, in %APPDATA%\Thoth. Uninstalling Thoth leaves them there, so reinstalling finds them. Settings → Backups makes backups of the whole library, and on Pro it can also keep encrypted copies in the cloud.

It checks for updates by itself and installs them when you restart. Settings → Data & about has a Check for updates button. Organizations that push updates themselves can turn this off for every computer (see Deploy to many computers).
