MemNote: Take notes, improve recall Stop losing fleeting ideas to the void. MemNote is the first context-aware note-taking application designed to work the way your brain does: by association. Most note apps are just static text editors. You write something down, but weeks later, you can't remember why you wrote it or where you were. MemNote solves this by automatically anchoring every thought to the time, place, and device where it was created—giving you total recall without the effort. Fast and mobile-first MemNote is fast and lightweight, available on all platforms, and designed from the ground up to be mobile-first. Automatic context logging You focus on the content; we handle the context. MemNote passively records: * Location: Automatically geotags notes so you can find them on a map later. * Time: precise timestamps to visualize your thoughts on a timeline. * Device: Know exactly which device you used -- did I take this note on my laptop, or on my phone while watching TV? Recall via association Map and timeline views allow you to browse notes by their meta-data -- if you took a note at that restaurant you were at last Tuesday, the note will show up at the restaurant location on the map, and at the time you took the note on the timeline. Local-first, private, and available everywhere Your thoughts are private and available everywhere, any time. For performance and reliability, we store and search notes locally. For backup and availability across devices, we sync notes to the cloud. Data is encrypted both at rest and in transit. Markdown native, no lock-in Write in pure Markdown. Your data is portable, readable, and never locked into a proprietary format. You can export your notes as a well organized zip file that contains any relative links and attachments. Meta-data is retained in YAML front-matter. AI compatible MemNote uses Markdown with LaTeX extensions to allow you to copy-paste responses from your favorite AI assistant into your notes without any formatting issues. Key features: * Fast startup * Offline-first reliability * Automatic geolocation & timestamping * Cross-platform synchronization (with native apps on Windows, MacOS, Android, and iPhone) * Beautiful, distraction-free interface * Powerful timeline & map views Don't just take notes. Improve recall. Download MemNote today and upgrade your second brain.
Overlay One

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.
