Memory Lens — the app that remembers what it sees, so you don't have to. Memory Lens watches the world through your phone camera or Ray-Ban Meta smart glasses and quietly writes down what it sees. Ask "Where are my keys?" and it answers with a real place and time, because it was actually looking: "I saw your keys on the desk today at 5:14 PM." Four simple modes, all big buttons and plain words: Memory — Watches and remembers. It logs what it sees, tracks your things, checks lists like "Don't let me leave without keys, phone, meds" against what it has genuinely seen, and keeps a searchable diary of your day. Voice notes stay as audio; everyday moments become text memories. Project — A patient building coach. Photograph an instruction sheet or scan its QR code and it breaks the page into steps, then watches your hands and coaches out loud: "Step done. Next: fold the corner" — or "Careful, that fold looks wrong." Show it two photos of an object and it learns to watch for that too. Fast Capture — One tap saves a moment you'd otherwise lose: a parking spot, a whiteboard, a label. Settings — Your AI key, free model choices, light/dark themes, and privacy controls. Built first for people with memory disabilities. Memory problems, brain injury, ADHD, early dementia, medication fog — the common thread is "it was right here a minute ago." Memory Lens carries the remembering for you: spoken guidance instead of reading, large text and touch targets, and answers you can simply ask for. That independence — not having to call someone to ask "did I take my pills?" — is the real product. Trust is the design. If the AI can't actually see your photo, the app says so and stops; it never invents a sighting, because a false "it's on the table" is worse than no answer. If the camera sees a private scene, watching stops and the photo is deleted. Keys and memories stay on your phone; kept photos are capped and auto-deleted after 30 days. Everyone else forgets too. The wallet in yesterday's jacket, the passport before the airport, "did I already add salt?" mid-recipe, furniture assembly at midnight with the app reading the step and checking your work, travel checklists verified against what was truly packed. For parents, it is a second pair of patient eyes for homework builds. Honest limits: real seeing needs an AI connection — a free cloud key works (with rate limits), a paid key removes them, or a small home server keeps it private. Glasses features need Ray-Ban Meta glasses. An on-device model can be downloaded, but it doesn't think yet — the app says so plainly rather than pretend.
