But nobody else offers you the ability to *just write* without needing to constantly remind the chatbot about what you’re working on. ## Up and running in minutes All you need is your MacBook, your notebook and your pencil. That’s it. # The world's first *visually grounded* AI tutor. **Milo** gives feedback in real-time using your on-paper problem-solving progress. Join For Free, Premium Upgrades Available The problem ## Homework help shouldn't mean *handing over the answer* A human tutor runs about $40 an hour — and isn't there at 11pm the night before a test. Answer apps just spit out the solution, so nothing sticks. Our AI tutor follows along on paper and guides your student to figure it out themselves. Simple setup ## Up and running in *three minutes* No special equipment. No complicated setup. Just your Mac and your notebook. ### Aim your camera at your textbook Open Knowable on your Mac and point your built-in webcam (or your iPhone via Continuity Camera) at your textbook or notebook. No extra hardware needed. ### Hit opt+M and ask Milo Press and hold `opt` + `M` to speak your question, or type it in chat. Milo sees the camera frame at that exact moment. Think about what "net force" means. What forces are acting on the object? ### Milo reads & replies Milo writes a guiding hint in chat — with LaTeX math rendered via SwiftMath — and speaks it aloud through TTS. You find the answer yourself. See it in action ## Watch Milo coach a session A real Knowable session: notebook on the desk, Milo following along, hints flowing as the student works. What makes it different ## Designed for how *high school students actually learn* ### Milo sees your textbook, not just your screen Traditional AI tutors only see what you type. Milo sees your actual textbook page through your Mac's camera. Press opt+M to ask a question by voice (or type it), and Milo answers about exactly what you're looking at. - opt+M push-to-talk voice + typed questions - Continuous camera feed via webcam or Continuity Camera - LaTeX-rendered math replies + spoken aloud via TTS - Never gives the answer — always a guiding question ### Any subject, any textbook Not just a math app. Milo runs on frontier vision models, so it reads diagrams, equations, handwriting, and prose across math, science, English, history, and languages — whatever your student puts in front of the camera. - Reads diagrams, graphs, and equations - Understands messy handwriting and printed prose - Coaches every core high-school subject - One app for the whole course load ### Hints, not answers — so it actually sticks The AI isn't doing your kid's homework. Milo never writes the answer. It nudges with a guiding question so the student reaches it themselves — which is exactly why they still remember it on test day. - Guiding questions instead of solutions - Builds understanding your child keeps - Only responds when your student asks - No copy-paste answers to hand in For everyone involved ## Knowable works for *you* Whether you're the one studying, the one paying for tutors, or the one teaching — Milo has something to offer. ### Like having your smartest friend *in the room with you* Studying alone is tough. With Milo, you'll get quality feedback anytime you want, just a few clicks away. Simple pricing ## Start free.

Camera frames, voice transcripts, and chat messages stream over TLS to AWS Bedrock (us-east-1), where Milo runs on foundation models. AWS contractually guarantees that your inputs and outputs are never used to train these models and are never shared with the model providers — the providers don't have access to the AWS accounts that run inference. Camera frames live only in memory during a session; they are not written to disk or to our database. Chat messages and session metadata (timestamps, event log, hint counts) are stored in our database on AWS (Amazon DynamoDB, us-east-1) — encrypted in transit and at rest — so sessions can continue across your Macs. We never share data with advertisers. See our 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 USD ($34.99 CAD) or $249.99/year USD ($349.99 CAD, save 17%) and includes 10,000 credits per month, with a 7-day free trial for new subscribers. Prices shown at checkout are set by your App Store region. If you ever run low, one-time credit packs are available as in-app purchases. Credit packs never expire. Subscriptions auto-renew through your Apple ID; you can cancel any time in App Store → Settings → Subscriptions. ## Does it just give answers? No — and this is the core of what Milo does. Every hint is a guiding question designed to nudge 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. Still have questions?
