mindmap.io vs Thinkvas: which should you use? (2026)

Thinkvas gets the hard part right. It rejects the single linear chat box and lets you branch off at any turn with full context inheritance on an infinite canvas, with a notepad for your own notes and a knowledge graph that connects ideas across documents. That is the same conviction mindmap.io is built on, so this is not a comparison between a thinking canvas and a diagram tool. It is two tools in the same category. The question this page answers is which one carries you further once the branching is no longer the novelty: when you need to pick a model per node, hand a branch to the AI to explore, collapse a hundred nodes to read them, and hand someone a map they can clone and keep building.

TL;DR verdict

Pick Thinkvas if you want a focused, document-grounded research canvas with long-term per-canvas memory, you like its knowledge-graph view, and an early academic beta is exactly the bar you need. Pick mindmap.io if you want to choose Claude, GPT, Gemini, or Grok per node and compare them in the same map, let auto-expand build a branch on its own, zoom an entire map down to keywords, ask your whole map and get citations back, and publish a link other people can clone. mindmap.io is free for up to 5 maps with limited AI built in, so you match Thinkvas on free mapping and get AI in every node too. A paid plan unlocks unlimited maps, every frontier model, higher limits, and Milo, the AI agent.

The comparison

Both tools believe the same thing about how thinking should work, and Thinkvas executes the core honestly. Its branching is real, its context inheritance is real, and its long-term canvas memory and knowledge-graph view are genuine ideas mindmap.io frames differently. mindmap.io leads on breadth: the model choice, the automation, the retrieval, the export, and the clonable link are the rows that turn a branching canvas into a daily working tool.

Mindmap: the same branching, with more ways to move once you are in it

Thinkvas and mindmap.io start from the same node. You fork at any turn, and the new branch inherits the full context above it. The difference is what you can do once you have fifty of those branches. In mindmap.io every node is a live thread you can also open as a normal linear chat when you want to read a path straight through, and per-map custom instructions let you set the voice and constraints once so every node in that map follows them. Navigation is keyboard-first, so forking, toggling a node between note and AI prompt, and jumping between branches are keystrokes rather than menu trips. On a public beta canvas the branching itself is solid in both tools. The gap shows up in the hundred small moves you make after the first ten branches.

AI capabilities: per-node models, auto-expand, and a map you can zoom to keywords

This is where the two tools separate most. Thinkvas does not publicly name the models behind it and offers no per-node model picker, so you cannot put Claude in one branch and Gemini in the next, and you cannot compare two models on the same question inside the map. mindmap.io gives you Claude, GPT, Gemini, and Grok switchable per node on one subscription with no API keys, so model comparison is a normal part of working a map. Auto-expand lets you set a direction and the AI asks its own follow-up questions and builds whole branches for you instead of you expanding one node at a time. AI zoom summaries condense every node across four levels, from Full to Tweet to Phrase to Keyword, so a hundred-branch map stays readable at a glance. You can search across the whole map and ask your whole map as a knowledge base, with answers that cite the nodes they came from. You can also point your own AI agent at mindmap.io over MCP or an installable skill to create and grow maps programmatically, while Thinkvas (thinkvasai.com) is a user-facing visual AI chat canvas (multi-threaded branching chats, infinite canvas, knowledge graph) founded 2025, and adversarial searches for an official API, MCP server, developer docs, docs subdomain, or 2026 changelog surfaced no programmatic surface for an external agent to create or build maps/nodes inside it. Thinkvas leans on its knowledge-graph view to connect ideas instead, which is a different and legitimate take, but the search, the citations, the auto-expand, and the four-level zoom are not in its public materials.

Sharing: a link people can clone, not just view

Thinkvas shipped view-only sharing in v0.7.0, so you can show someone your canvas. mindmap.io takes the next step. Export any map to Markdown, PNG, JSON, or a clean chat transcript, or publish a public, interactive share link that other people can explore node by node and clone to make their own copy. The honest credit to Thinkvas here is its long-term per-canvas memory: the canvas remembers across sessions, which is a real persistent-context feature mindmap.io approaches through branch context rather than stored memory. But a reader of your Thinkvas canvas sees your thinking. A reader of a mindmap.io map can walk it, branch it, and take it with them.

Choose mindmap.io if

• You want to choose Claude, GPT, Gemini, or Grok per node and compare two models on the same question in one map.
• You want auto-expand to explore a direction for you and AI zoom summaries to step back from a hundred branches at a glance.
• You need to search the whole map and ask it as a knowledge base, with answers that cite the exact nodes.
• You want to export to Markdown, PNG, JSON, or transcript and share a link readers can clone, all free to start.

Choose Thinkvas if

• Your work is document-grounded research and reading, and a connected knowledge-graph view is how you want to see it.
• Long-term per-canvas memory that carries across sessions matters more to you than per-node model choice.
• You are fine on a single hosted model and do not need to compare Claude against Gemini in the same map.
• An early academic beta from a non-profit, built around reading and research synthesis, is exactly the bar you need right now.

What Thinkvas does well

Thinkvas earns its place in this category instead of faking it. The branching is true forking at any turn, the context inheritance runs down each branch, and the infinite canvas keeps your own notepad next to the AI threads, so the fundamentals are well executed rather than bolted on. Its knowledge-graph layer visually connects ideas across documents and conversations, its long-term per-canvas memory is a real differentiator, and its academic positioning around reading, writing, and research synthesis lands with the students and researchers who use it, some of whom prefer it over linear tools like Gemini and NotebookLM. The trade-off, visible in its public footprint, is that it is an early v0.7.0 beta from a small non-profit with no pricing page, no docs, and no model disclosure, so the surrounding feature set, models, search, export, and summarization is thin next to a more mature tool.

FAQ

Is mindmap.io a good Thinkvas alternative?

Yes, and it is a close-category one. Both tools branch at any turn with full context inheritance, so if Thinkvas matched how you think but you wanted per-node model choice, auto-expand, whole-map search, and a clonable share link, mindmap.io covers the same core with a broader, more mature feature set around it.

Does mindmap.io generate a mind map from an article like Thinkvas does?

Yes. Paste text or an article and mindmap.io builds an interactive map of real note nodes you can keep working. Thinkvas is built around document-grounded canvases too, but mindmap.io’s generated nodes stay live: you can question them, switch their model, auto-expand them, and zoom them down to keywords.

Can I use Claude, GPT, and Gemini in mindmap.io?

Yes. You get Claude, ChatGPT, Gemini, Grok, and more on one subscription with no API keys, and you can switch the model per node and compare answers side by side in the same map. Thinkvas does not publicly name its models or offer a per-node picker, so this is one of the clearest differences.

Does mindmap.io have long-term canvas memory like Thinkvas?

Not in the same form, and that is an honest point for Thinkvas. Thinkvas keeps long-term memory within a canvas across sessions. mindmap.io carries context through the branch above each node rather than storing persistent memory, which keeps the reasoning explicit and visible on the map. If a remembering canvas is your priority, Thinkvas does that today.

Does mindmap.io have a mobile app?

No, and that is deliberate. mindmap.io is built for the big screen where real thinking happens, with keyboard-first navigation and room to see a whole map. It is a focused desktop tool by design rather than a phone-first one.

Is mindmap.io free?

Yes. mindmap.io is free for up to 5 maps with limited AI. A paid plan unlocks unlimited maps, every frontier model, higher limits, and Milo. You never need to bring your own API keys. Thinkvas is also free during its beta, so the real comparison is feature depth, not price.

Try the branching canvas that does more once you are in it

Thinkvas and mindmap.io agree that one linear chat is the wrong shape for real thinking. mindmap.io goes further inside the map: choose a model per node, hand a branch to auto-expand, zoom every node to keywords, ask the whole map and get citations back, and publish a link people can clone.
