Most of your best ideas happen when you're not at your desk. Syno is built for that. Tap the mic, say what's on your mind, and Syno figures out the rest. It sorts your words into tasks, reminders, notes, memories, and calendar events without you having to think about where anything goes. WHAT'S INSIDE Thoughts. Voice recordings that get transcribed and saved. Search them later, replay them, favorite the ones that matter. Memory. A place for the stuff you want to remember but always forget. Restaurant recommendations, important info, random facts, categorized automatically. Tasks. Organized by context, not just a flat list. Work, Home, Health, Finance, Shopping, whatever fits your life. Reminders. Set them by voice. See them on a calendar. Actually get reminded. Lifestyle. Habit tracking that doesn't feel like a chore. Toggle what you did, skip what you didn't, move on. Projects. For the things that take longer than a day. Track progress, set goals, watch it move forward. Mindspace. Typed notes when you want to write instead of speak. Tags, sorting, search, it's all there. Calendar. Connects to Google, Outlook, and iCloud so your schedule lives in one place. HONEST PITCH Syno won't change your life if you don't use it. But if you're the kind of person who loses thoughts, forgets follow-ups, or just wants less mental clutter, it's worth trying. It's fast, it stays out of your way, and it actually works.

You think out loud. ThinkAloud writes it down. Hit record and just talk: a passing idea, a meeting, a whole lecture. When you stop, you can play the recording back and decide whether it's worth keeping before anything happens to it. Only then does the on-device AI turn it into a real note, with a title, some structure, tags, and links to the related notes you already have. Here's the part that matters. All of this happens on your phone. ThinkAloud runs Google's Gemma model locally, so your voice and your notes never get uploaded anywhere. There's no account to create, no server in the middle, and nothing to pay every month. You download the model once, and after that it works offline. Your notes are just Markdown files in an ordinary folder, the same format Obsidian uses. Point ThinkAloud at a vault you already have, or let it keep one for you. Either way you can open, edit, or back them up with any app you like. Nothing is trapped inside. What it's good at: - Voice, photos, or quick text go in; clean, tagged notes come out - Ask your notes a question in plain language and get an answer with its sources listed, so you can tap straight through to where each fact came from - A knowledge graph that builds itself as your notes start linking up - Full-text search, tags, folders, and checklists - Optional sync to your own Google Drive or iCloud. Your account, a private folder, no servers of mine in between. No ads, no analytics, no tracking, no accounts. I made ThinkAloud because I wanted a notebook that was actually mine. That's the whole idea. The on-device model needs around 3 GB of free space and a fairly recent device.
