Who can try it?
Any IB student aged 13 or over: download it and sign in with your Apple ID or a personal Google account.
Can I use my school Google account?
Maybe not: schools on Google Workspace often block students under 18 from apps the school hasn't approved. Sign in with Apple or a personal Google account instead, or ask your school's IT to allow Lesson Leech (the details are under For schools).
How fast are the answers?
About a second from the teacher's question to the answer on your screen: the median in our tests was 0.8 seconds. Rhetorical questions ("…, right?") are skipped. When the answer is a fact that changes, like a company's latest figures, a web search checks it a few seconds later.
Can I ask it my own questions?
Yes. During a lesson, click Leechy and type into Ask Leechy: "what did she mean by elasticity?", "who was that economist?". It answers from what your teacher has been saying.
Does it know the grade I'm aiming for?
If you tell it. Add your predicted and target grades in Account & privacy and your notes, summaries and flashcards are pitched at the jump you want to make. It's optional, and you can remove them any time.
Do I need my teacher's permission?
Yes. Classmates can be heard in a recording too, so always ask the teacher before you start listening.
Does it record the lesson?
It listens and turns speech into text on your Mac. The audio is deleted when the lesson ends; only the words are used for your notes.
Why does the installer ask for my password?
It puts Lesson Leech in your Applications folder, and your Mac asks for its password before any installer does that. Lesson Leech is signed and checked by Apple, so it opens straight away. Rather drag it in yourself? Get the disk image and drag Lesson Leech onto Applications.
Does it work on Windows?
Yes, on Windows 10 or 11. Download for Windows opens Lesson Leech in the Microsoft Store: click Get, then Open, with no warnings to click through. It does everything the Mac app does, and Leechy sits at the top of your screen.
My school Google account won't sign in
Schools usually block students under 18 from apps they haven't approved, so Google stops the sign-in before it reaches us. Sign in with Apple or a personal Google account instead, or ask your school's IT to allow Lesson Leech.
Windows, iPad or phone?
Not yet. Lesson Leech sits under the MacBook's notch and uses the Mac's chip for speech-to-text. Other devices may come later.
How do I delete my data?
In the app: click the worm › Account & privacy › Delete account. That removes everything the server has about you; your lessons on your Mac stay unless you delete them too.
