Synap is your memory, externalized. Everything you know, carried outside your head, connected, and yours. Your mind was never meant to hold all of this. Keep a thought in Synap and it stays exactly as you wrote it, on the day you wrote it. Synap connects it to what you already kept, on its own. Nothing to file, nothing to tag. Ask for it back in your own words and the answer comes from your own entries, each one cited. Synap works with or without AI. Keeping, search and the record all run on your iPhone. Bring an assistant when you want one, or do not. Either way the record is yours, on your own device. KEEP ANYTHING, IN SECONDS Type it, say it, share it from any app, or speak it into your Apple Watch. Workouts you record with Apple Watch or any app that saves to Health land in your memory on their own, route included. FIND IT BY MEANING Search understands what you meant, not just the words you used. It runs on your phone, so it works with no signal. ASK YOUR OWN MEMORY Ask a question and get an answer drawn from your own entries, with the exact entries it came from. Use Apple Intelligence on a supported iPhone, sign in with your Claude account, or connect ChatGPT or Gemini. Your entries stay on your phone until you ask. SEE WHAT YOU MISSED Insights reads across everything you kept and shows the patterns, the contradictions and the blind spots. Reflect shows the shape of a season of your thinking. Open the whole record as a map you can move through. BRING WHAT YOU ALREADY HAVE Import your ChatGPT and Claude history and it becomes part of the record the moment it lands. ON YOUR HOME SCREEN AND YOUR WRIST Widgets for today, the record, recent entries and your body. Live Activities while something is being kept. A watch app that leads with one Speak button. PRIVATE BY DESIGN Synap is local first. Your entries, your search and your voice transcription run on your device. Cloud sync is optional and off until you turn it on. Names can be hidden before anything is sent to an AI you connect. FREE Keeping, search and the record on your phone, import of your ChatGPT, Claude and Obsidian history, new entries connected to what you already kept, and a cloud account with sync for up to 1,500 entries. PRO Chat that draws on your whole memory. Patterns, contradictions and blind spots, read for you. An evening digest of what was kept and what connected. Sync in the background, even with the app closed. No cap on what you keep. Know more. Carry less. Terms of Use: https://synap.ing/terms Privacy Policy: https://synap.ing/privacy

Card Game Prototyping & Playtesting Tool DeckForge is the fastest way to design, build, and playtest custom card games on your phone. Stop printing paper prototypes — create your entire tabletop deck digitally and start shuffling in minutes. Whether you're a board game designer iterating on a new card game or a group of friends playtesting a homebrew, DeckForge gives you everything you need to go from idea to play session without cutting a single card. **BUILD YOUR DECK** Create cards individually or generate entire decks at once with the bulk card wizard. Set names, colors, tags, types (cards, tokens, tiles), quantities, and custom characteristics. Duplicate decks to branch your design without losing previous versions. Import and export decks as JSON to share with collaborators. **DESIGN CUSTOM CARD LAYOUTS** Use the drag-and-drop card designer to build visual templates for your cards. Place text, icons, and images anywhere on the canvas. Bind fields to card data so every card renders with its own stats. Design a custom card back for your deck. Apply templates to individual cards or entire sets in one tap. **PLAY LIKE IT'S ON THE TABLE** Shuffle, draw, discard, and flip cards with smooth animations and haptic feedback that feels like a real tabletop experience. Tap any card to inspect it, move it between piles, or trigger game actions. Pinch to zoom on card details. Create custom piles — draw decks, hands, discard piles, fields — to match any game's layout. **THREE REALISTIC SHUFFLE ALGORITHMS** Choose how your deck shuffles: Fisher-Yates for perfect randomization, Overhand for a casual table shuffle feel, or Riffle for authentic card-game shuffling. Configure pass and cut counts for the simulation style you want. **LOCAL MULTIPLAYER — 2 TO 6 PLAYERS** Pass the device and play with friends. DeckForge supports 2–6 players with custom names, color-coded turns, a privacy screen between handoffs, and an optional turn timer. A full action log tracks every draw, discard, and move so no one loses track of the game. **ADD GAME LOGIC WITHOUT CODE** Attach scripts to any card using a visual builder — no programming required. Set triggers (on draw, on play, on discard, on tap, on flip), add conditions, and define actions like drawing extra cards, moving cards between piles, shuffling, flipping, adjusting counters, or displaying messages. Your game rules run automatically during play. **TRACK YOUR STATS** The statistics dashboard shows draw probabilities for every card, tag, and color in your deck. After playtesting, review balance scores, most-drawn cards, total playtime, and auto-generated insights to refine your game design. **SESSION TEMPLATES** Save starting layouts so you can replay the same setup instantly. Define which piles exist, how many cards each starts with, face-up or face-down orientation, and which piles are player-specific. Start a four-player game with a single tap. **EXPORT FOR PRINT** When your game is ready, export a print-ready PDF with crop marks, bleed, and CMYK color support. Home print and print-shop presets are built in. Printer Friendly option black/white grayscale.
