What is Knowable?
Knowable is an AI coach called Milo designed specifically for high school students that coaches through math and physics problems in real time. The tool uses macOS Desk View to see your actual textbook or notebook through your Mac's camera and guides you through every subject without giving the answer away. It provides Socratic hints instead of answers, helping students build real understanding by discovering solutions themselves.
Key features include live coaching where Milo sees your textbook through your Mac's camera, push-to-talk voice questions via opt+M keyboard shortcut, typed chat questions, continuous camera feed via webcam or iPhone via Continuity Camera, LaTeX-rendered math replies through SwiftMath, and spoken responses via text-to-speech. The tool covers every subject in high school textbooks including math, science, English, history, and languages.
Knowable is built for high school students who want to learn any subject, parents paying for tutors who want available-at-midnight support before exams, and teachers looking for a tool that builds real understanding. It's a macOS-only application requiring macOS 14 (Sonoma) or later, made in Canada by its founders.

Frequently asked questions about Knowable
Is my child's data safe?
Camera frames, voice transcripts, and chat messages stream to AWS Bedrock (us-east-1) over TLS so Milo can run on open source foundation models. Sessions save locally on your Mac and sync across your devices, and we never share data with advertisers. See their Privacy Policy for the full breakdown.
What do I need to use Knowable?
Just a Mac running macOS Ventura or later. Knowable uses your Mac's built-in camera in Desk View mode to see your notebook — no extra hardware required. Place your notebook on your desk, open the app, and you're ready to go.
What subjects does it cover?
Every subject in your high school textbook. Milo coaches across math, science, English, history, languages, and more — anything you can put in front of the camera. Milo runs on frontier foundation models with vision capabilities, so it reads diagrams, equations, prose, and handwriting in any subject.
How much does it cost?
Knowable is free to start — every account gets 1,000 credits each month, forever. Knowable Plus is $24.99/month or $249.99/year (save 17%) and includes 7,000 credits per month, with a 7-day free trial for new subscribers. One-time credit packs are available: $4.99 for 500 credits or $24.99 for 3,000 credits. Credit packs never expire. Subscriptions auto-renew through your Apple ID.
Does it just give answers?
No — and this is the core of what Milo does. Every hint is a Socratic question designed to guide you toward the answer, not to give it to you. Milo is built on the research principle that students learn best when they discover the answer themselves, with just enough nudging to get unstuck.
What if my child doesn't want help?
Milo only responds when you ask. Press and hold opt+M to ask a question by voice (push-to-talk — release when you're done), or type in chat. Milo doesn't volunteer interruptions; if you want to work independently, just don't ask.
How does the camera feature work?
Open Knowable on your Mac and point your built-in webcam (or your iPhone via Continuity Camera) at your textbook or notebook. Press opt+M and ask Milo — the camera grabs the current frame alongside your prompt so Milo answers about exactly what you're looking at. No extra hardware needed.
Can I cancel my subscription?
Yes, you can cancel any time in App Store → Settings → Subscriptions. Subscriptions auto-renew through your Apple ID, but cancellation stops future renewals while keeping your access until the end of your current billing period.
Does Milo work with handwritten notes?
Yes, Milo runs on frontier foundation models with vision capabilities that read diagrams, equations, prose, and handwriting in any subject. Anything you can put in front of the camera works, including handwritten notebook pages.
