Overlay One
Read full descriptionHide full description
Overlay is an AI assistant with a memory. Capture anything — a note, a task, a link, a half-formed idea — and Overlay's brain organizes it, connects it, and remembers it. Then you can chat with everything you know. Most apps make you file things away and dig them back out. Overlay does the filing for you and brings the right context back the moment you need it. WHAT YOU CAN DO • Capture in one tap — Jot a quick note from anywhere. Overlay's brain decides whether it's a note, a task, or something worth remembering, so you never stop to choose. • Chat that actually knows you — Ask questions and get answers grounded in your own notes, tasks, and saved pages — not a blank-slate chatbot. • Tasks, automatically — Action items are pulled out of what you capture. No separate to-do ritual. • A brain that grows — Overlay builds a living memory from what you save: the people, projects, and topics you care about, and how they connect. • Your best prompts, saved — Keep the prompts you rely on a tap away. ONE BRAIN, EVERYWHERE Overlay works on iPhone, in your browser, and on the web — all synced. Save a page from your laptop and it's waiting in your pocket. Every capture is tagged with where it came from, so nothing gets lost. BUILT ON THE BEST MODELS Overlay runs on leading AI models, including Anthropic's Claude and Google Gemini, choosing the right one for the job. PRIVATE BY DESIGN Your knowledge is yours. Everything is secured per-account, and you stay in control of what Overlay remembers. Stop losing your best thinking. Scale your brain.

You read a hundred things a month and remember almost none of them. Not because you weren't paying attention, but because nothing was keeping the thread. Mneme remembers it. Send it a link, a video, a PDF, or a half-formed thought. It reads it, sets it beside everything you already think, and tells you when the two argue. A MAP THAT DRAWS ITSELF Everything you save lands on a map, near the ideas it already belongs with. You don't file anything, tag anything, or maintain anything. Topics form on their own and drift as you change. Zoom into one and it opens as a smaller map of its own. IT NOTICES WHEN YOU CONTRADICT YOURSELF Most apps store what you save. Mneme reads it. When something you saved this week disagrees with something you believed last month, it tells you — and shows you exactly where the two split. It also tells you when a thread is picking up speed, when different roads arrive at the same place, and when something you cared about has gone quiet. FIVE WAYS IN Atlas: the map. Every capture, placed by meaning. Mind: what's moving. Threads, tensions, convergences, dormant ground. Archive: the plain list, for when you just want to find the thing. Pulse: a check-in on what the people you follow have been engaging with. You: the long view. Your streaks, your busiest hours, and dozens of other insights. CAPTURE FROM ANYWHERE Share sheet, camera roll, or your own voice. Articles, YouTube, TikTok, Instagram, PDFs, screenshots, book pages, quotes, and thoughts you haven't finished having yet. Most captures land in a few seconds. Bring your history with you: import your existing links, or connect Letterboxd and Goodreads so what you watch and read shows up on its own. IT COMES BACK TO YOU Mneme surfaces one thing a day worth thinking about again — a contradiction that formed while you weren't looking, a thread gathering pace, something you saved a month ago and forgot. No unread counts. No pile. Nothing to clear. Mneme is free with ads and monthly capture limits. Mneme Plus ($2.99/month) removes ads and raises the limits. Subscriptions renew monthly and can be canceled anytime. 'Mneme' was one of the three original muses, before there were nine. Melete for practice, Aoide for song, and Mneme for memory. This one is for Mneme. Terms of Use: https://mneme-app.com/terms.html

Verdict
The clearest difference is in-app purchases: Overlay One at none against Mneme's 3. Overlay One also leads on ads (none vs shown). Mneme's advantage is update cadence (every 10 days vs every 3 weeks) and iOS requirement (16.4 vs 18.0). On price and device support there is nothing between them.
