Work with your AI in maps, not text. Until now, working with an AI meant trading lines of text back and forth. The longer the chat, the further your decisions and open tasks scroll out of sight. Matryoshka Mind Map turns that conversation into nested to-do lists and Mermaid diagrams, so you and the AI you already use work from the same picture. Paste one connector URL into your AI (such as Claude). Your AI writes into your map, draws diagrams, and reads the checks you make. You see it at a glance in the app, fix things, and check them off. There is no AI inside the app. It connects to the AI service you already use. Link a Google, Apple, or email account to start. Items nest inside their parent; swipe left to drill down, or switch to a classic mind map view. On phone, tablet, and web. ■ Maps, not text ・Your AI writes — Ask "turn today's meeting into to-dos" or "draw this process as a diagram," and nested to-dos or a Mermaid diagram land in your map ・You see and fix — No need to scroll back through the chat. Open the map and see everything at once. Reorder and check off with your finger ・Your AI reads back — Your AI sees the checks and edits you made in the app. Ask "what's left?" and it answers from your map ・Connect via URL — Paste the connector URL into your AI. No extra installs ・No AI inside the app — The app generates nothing on its own; it works with the AI you already use ■ Two ways to see your map ・Matryoshka view — Child items sit inside their parent card. Swipe left to drill down; go back and it shrinks into place ・Mind map view — See the whole map with branches spreading from the center. Add, edit, and delete items here too ■ Reshape the hierarchy with your finger ・Tap — edit text ・Swipe left (or click ">") — go inside that item ・Press and hold to grab — reorder, nest into another item, or move up a level ・Swipe right anywhere — go back one level (at the top level, back to map list) ■ A nested to-do list, too ・Choose "TODO" when creating a map and every item gets a checkbox ・Checking a parent marks everything inside it as done ・Add due dates and start dates. Color highlights show overdue and due-today tasks ・Get reminders before due dates. Tap to open that item's map ■ Related maps ・Relate an item to other maps. Tap a related map on the card to open it ・The relation graph shows how all your maps connect, at a glance ■ Documents and diagrams ・Add Markdown documents as items: write one in the app or import a .md file ・Shown formatted with Mermaid diagrams drawn in place ・Share or save them as .md files. AI agents can also read and create documents ■ On your phone and on the web Sign in with the same account to use the same maps on your phone, tablet, and the web (matryoshkamap.web.app). Start with no sign-up, and link an email, Google, or Apple account later. ■ Share & export ・Collaborate on maps by entering another user's email address ・Publish a read-only view to anyone with the link ・Copy or share as indented text, or Markdown with checkboxes and due dates ■ Free and Premium The free plan includes up to 20 maps with 300 items and 3 documents each (with banner ads).
