New mind map view: see your nested ideas spread out from the center. Due dates and reminders, too. Use the same maps on your phone and the web.
A mind map designed for digging deep into ideas rather than spreading them out.
Standard mind maps get cluttered as they grow. Matryoshka Mind Map nests child items inside their parents and lets you drill down one level at a time with a swipe. When you want the big picture, switch to a classic mind map with branches spreading from the center. Use it for brainstorming, nested notes and breaking down to-dos — on your phone, tablet and the web.
■ Two ways to see your map
・Matryoshka view — child items are drawn inside their parent card. Swipe left and the item under your finger grows into the next level; go back and it shrinks back into place. Nested screens show a level number next to the title.
・Mind map view — see the whole map with branches spreading left and right from the center. You can add, edit and delete items here too
■ Reshape the hierarchy with your finger
・Tap — edit the text
・Swipe left (or click ">" at the right end of a row with a mouse) — go inside that item
・Press and hold to grab — reorder within a level, drop into another item, or move up to the parent level
・Swipe right anywhere on the screen — go back one level (at the top level, back to your map list)
■ Spin off or merge branches
Grab a top-level item and drop it on the header at the top to turn it, with everything inside it, into a new standalone map. You can also merge maps back together into one. Reorganize the structure any time.
■ Related maps
・Relate an item to other maps. Tap a related map on the card to open it
・On a related map, see which items it is related to
・The relation graph shows how all your maps connect, at a glance
■ 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. Overdue and due-today items are highlighted, and items not yet started are dimmed
・Get a reminder before a due date. Tap it to open that item's map
■ On your phone and on the web
Sign in with the same account to read and edit the same maps on your phone, tablet and the web (matryoshkamap.web.app). Use your phone on the go and your computer at your desk. Start anonymously with no sign-up, and link an email address, Google or Apple account later.
■ Connect directly with AI agents
We've released a free companion tool that lets MCP-compatible AI agents like Claude Desktop and Claude Code read and write your maps directly. Just say "organize what we talked about into a map" or "I finished that task," and it's reflected in your map.
■ Share & export
・Edit the same map together with other users just by entering their email address
・Publish a read-only view to anyone with the link
・Copy or share as indented text, or as Markdown with checkboxes and due dates
・Paste a Markdown list to import it as a new map
・URLs in items automatically become tappable links
