Quick answer
MindMap AI imports Coggle mind maps natively. In Coggle, open the download menu and choose the .mm option. In MindMap AI, open Canvas, go to All Projects, click Import Project, and select the file. Your hierarchy, node text, links, and collapsed branches all come across, and importing is free on every plan.
Coggle is a clean, fast way to get ideas out of your head. Unlimited public diagrams, real-time collaboration, and unlimited image uploads on the free plan make it a reasonable place to start. What it does not do is help you develop an idea once the structure exists. Every node, every branch, and every reorganization is yours to type.
If you want to keep the structures you have already built and put an AI copilot behind them, you do not need to rebuild anything. MindMap AI has imported Coggle mind maps since v2.0.22, released on 16 May 2026, alongside FreeMind and Mapify. This guide covers the export, the import, exactly what survives the trip, and what to do about the two things that do not.
What you need before you start
- A Coggle diagram you can download. If you do not see the download icon on a diagram, either you are not signed in or the person who shared it has not granted download permission.
- A MindMap AI account. The free plan is enough. There is no import limit and no credit cost.
- A .mm file under 20 MB. There is no node limit as such. The parser caps at 100,000 XML elements and 50 levels of nesting, which works out to roughly 100,000 nodes and about 48 levels deep. Heavily formatted maps reach the element cap sooner, because markup inside nodes counts toward it. No real Coggle diagram comes close to any of this.
- Two minutes. Most maps import in seconds.
Step 1: Export your Coggle diagram as a .mm file
Open the diagram in Coggle and click the download icon in the top right of the canvas. Coggle offers several formats, including PDF, PNG, a plain-text outline, Microsoft Visio (.vsdx), and .mm.
Choose .mm. This is the FreeMind mind map format, and it is the only Coggle export that preserves your hierarchy as structured data rather than as a flat picture or a flat list. Coggle generates version 0.9.0 of the format, and the file contents are XML, as set out in Coggle's own export documentation.
Save the file somewhere you can find it. If you are moving several diagrams, download them one at a time. Coggle only offers bulk export on its Organisation plan.
Step 2: Import the .mm file into MindMap AI
Sign in at MindMap AI. If you are new, you can sign up with Google, Apple, or email in under a minute.
Open the Canvas page, click All Projects, then click Import Project. Select the .mm file you downloaded from Coggle and confirm.
Your diagram opens as a fully editable MindMap AI project. Your Coggle central topic becomes both the root node and the project title, so the map is already named when it lands. Branches keep the left and right placement they had around the centre, collapsed branches arrive collapsed, and every node is immediately editable by hand or by AI. Nothing is read-only and nothing sits behind a paid tier.
Step 3: What carries over from Coggle, and what does not
The .mm format is a structural interchange format, not a screenshot. It carries your thinking and your links, but not Coggle's visual treatment. Coggle's own documentation is explicit that the .mm export cannot represent everything in a Coggle diagram.
| Coggle element | Comes across | Notes |
|---|---|---|
| Central topic | Yes | Becomes your root node and the project title |
| Branches and sub-branches | Yes | Full parent and child hierarchy |
| Left and right branch placement | Yes | Side placement around the centre is preserved |
| Node text | Yes | UTF-8 throughout, so accented and non-Latin characters are safe |
| Hyperlinks on nodes | Yes | Both node link attributes and inline links, with anchor text kept as the label |
| Collapsed branches | Yes | A folded branch imports folded, with its children hidden |
| Markdown in node text | Cleaned up | Heading hashes and bold asterisks are stripped so topics read naturally. Emoji shortcodes are kept as they are |
| Node notes | No | Rich-content note panels are ignored during import |
| Branch colors and line styles | No | Style attributes are dropped and a MindMap AI theme is applied instead |
| Images inside nodes | No | Image elements are not parsed. Re-add them in MindMap AI, where images are unlimited on every plan |
| Additional start points | First one only | See below |
| Comments and chat | No | Coggle conversation history stays in Coggle |
| Change history | No | Your MindMap AI version history starts fresh at import |
If your diagram has more than one start point
Coggle lets a single diagram have several independent start points. MindMap AI imports the first one and drops the rest. Nodes floating loose on the canvas, attached to nothing, are skipped as well.
Fix this before you export rather than after you import. In Coggle, drag your other start points so they hang off the main one, then download the .mm file. Everything arrives in one map with nothing missing.
Looped branches
MindMap AI reads loop connections out of a .mm file and turns them into labelled arrows on the canvas, so a connection that jumps between branches survives the import. The one exception is a self-loop, where a connection starts and ends on the same node. Those are skipped.
The catch is upstream: Coggle's documentation names looped branches as an example of what its own .mm export cannot represent, so in most cases the loop is lost on the way out of Coggle rather than on the way into MindMap AI. If a connection matters, note it before you export and redraw it as an arrow in MindMap AI, which takes seconds.
Step 4: Put the AI copilot to work on it
This is the part Coggle cannot do at all. Once your map is inside MindMap AI, it stops being a static diagram and becomes something you can keep developing through conversation.
- AI copilot. Chat your way from a rough imported structure to a finished chart. The copilot works incrementally, so your existing nodes and manual edits are preserved rather than overwritten.
- AI expand. Pick any node from your old Coggle map and grow it in one click. Useful when a branch was a placeholder you never got back to.
- AI summaries. Turn a long, wordy branch into a one-line summary without deleting what sits underneath it.
- AI relationships. Have the AI find and link related ideas across different branches, which is the connection type a strict tree structure hides. This is also the fastest way to restore any loops Coggle dropped on export.
- AI focus topic. Rebuild the chart around a single branch when that branch has outgrown the map it lives in.
- AI themes and AI styling. Ask for a visual style in plain language instead of recoloring branches one at a time. This is how you replace the Coggle styling that did not survive the export, in one prompt rather than node by node.
- AI retry prompt. If a result is not what you wanted, retry it. Retries do not use credits.
You can also switch the same content between a mind map, a logic chart, and an organization chart, or drop into outline view to think in text while the map updates alongside you.
Importing more than one Coggle diagram
There is no cap. MindMap AI's free plan includes unlimited imports, unlimited projects, and unlimited storage, so a full migration costs nothing.
The bottleneck is on the Coggle side. Bulk export is an Organisation-plan feature, so on the free or Awesome plan you download each diagram individually before importing. If you have a large library, work through it in batches and import as you go rather than downloading everything first.
Troubleshooting
The import failed or the file was rejected
Confirm the file extension is .mm and not .txt, .pdf, or .vsdx. Coggle's download menu offers all of these and it is easy to grab the wrong one. Also check the file is under 20 MB.
The map came in flat, with everything on one level
This usually means a plain-text outline was exported instead of the .mm file. The outline uses indentation to represent structure and does not always reconstruct as a hierarchy. Go back and choose .mm.
A whole section of the diagram is missing
It was almost certainly a second start point, or a group of nodes not connected to anything. Only the first start point imports. Reattach them under your main topic in Coggle and export again.
My node notes did not appear
Rich-content note panels are ignored on import. If the note text matters, move it into the node title in Coggle before exporting, or add it back in MindMap AI.
Accented or non-Latin characters look wrong
Both Coggle's export and MindMap AI's importer are UTF-8 throughout, so this should not happen. If it does, send us the file through Help and Support so we can look at it.

Coggle is genuinely good at what it is for. If your work is simple diagrams built collaboratively in a browser, it holds up. The gap opens when you want the tool to help you think rather than just record what you already thought.

FAQ
Yes. MindMap AI has imported Coggle mind maps natively since version 2.0.22, released on 16 May 2026. Export the diagram from Coggle as a .mm file, then use Import Project on the Canvas page to bring it in. The result is a fully editable project, not a read-only copy, so you can edit nodes by hand or ask the AI copilot to expand and reorganize them straight away. Importing is free on every plan, consumes no AI credits, and has no file limit.
Use the .mm option in Coggle's download menu. It is the FreeMind mind map format, and Coggle generates version 0.9.0 of it as XML. It is the only Coggle export that preserves your hierarchy as structured data. PDF and PNG exports are flat images, and the plain-text outline relies on indentation that does not always reconstruct cleanly. Picking the wrong format is the most common mistake, because Coggle offers all of them in the same menu.
Most of your work does carry over: the full hierarchy, node text, hyperlinks with their anchor text, collapsed branches, and left and right branch placement. What does not survive is Coggle's visual layer and its conversation layer. Branch colors, line styles, images inside nodes, node notes, comments, chat, and change history all stay behind. One structural limit matters most: if your diagram has several start points, only the first imports.
Yes, though you are unlikely to meet it. A .mm file must be under 20 MB, and MindMap AI's parser accepts up to 100,000 XML elements and 50 levels of nesting, which works out to roughly 100,000 nodes and around 48 levels deep. Maps with heavy formatting inside node text reach the element ceiling sooner, because that markup counts toward the same limit. A large Coggle diagram is typically a few hundred kilobytes, so any real map will import.
MindMap AI places no limit on imports. Its free plan includes unlimited imports, unlimited projects, and unlimited storage, so migrating a full Coggle library costs nothing and consumes no AI credits. The constraint sits on the Coggle side: bulk export is only available on Coggle's Organisation plan at $8.00 per member per month, so on the Free or Awesome plan you download each diagram separately. For a large library, work in batches.
Yes. The free plan includes unlimited projects, nodes, edits, images, storage, and imports, plus AI credits with no trial period and no paywall in front of the AI features. Paid plans start at $9.99 per month for Basic and add more AI credits and team features when you need them. You do not need a credit card to sign up, or a paid plan to import a Coggle diagram or run AI actions on it.
Yes, and this is the main reason people move. Once your Coggle structure is imported, AI expand grows any node into deeper subtopics, AI summaries condense a long branch into one line, AI relationships links ideas across branches, and AI styling restyles the map from a plain-language prompt. The copilot works incrementally: it builds around the nodes you already have rather than regenerating from scratch. Retries cost no credits.
It depends on what is slowing you down. Coggle suits simple, collaborative diagrams built by hand in a browser, and its free plan is generous on public diagrams and image uploads. MindMap AI suits people who want the tool to participate in the thinking: generating maps from documents, audio, and video, expanding branches on request, and restyling on command. If your Coggle work is mostly manual typing, MindMap AI is the stronger fit.
