[Compare](https://mindmax.me/vs/) · Facts checked 2026-11 ## Using MindMax with ChatGPT, Claude or Gemini You already hand PDFs to one of these assistants, and MindMax does not ask you to stop. All three connect to MindMax over a local MCP link: the assistant calls MindMax’s tools, reads the folder you have open, returns quotes that open on the page, and proposes edits you review — while keeping its own model and its own chat. On Gemini the connection goes through its CLI, which is the side of Gemini that can run a local MCP server. You get the document depth without leaving the app you already use. ChatGPT · Claude · Gemini The assistant you already use for PDFs — its model, its chat, its ecosystem. All three connect; Gemini through its CLI. MindMax A local MCP server on your folder: the documents, the reading map, the canvas and the review gate.

Each row says how. | Topic | With the MCP link | How to check for yourself | | --- | --- | --- | | Carries over | | | | Your model | Stays the one your assistant runs. MindMax runs none of its own models on this path, so no second bill for the thinking. Bring your own key → | Ask which model answered; it is the assistant’s own, not a MindMax model. | | Your files | MindMax opens the folder you already have — nothing imported, nothing copied, nothing locked in. Your folder, opened in place → | Open the folder in MindMax; the files in your file manager are unchanged. | | Adds | | | | The whole folder, not one upload | The assistant’s Projects raise the upload ceiling but still cap files per project. The link reads the whole folder MindMax has open — your fortieth paper is as reachable as the first. | Add a paper you added months ago and ask about it; the link reaches it without re-uploading. | | Reading maps for long documents | A long book comes back as a map — two levels of structure, a note per chapter — so the assistant reads the chapter it picks, whole, not as one upload. | Ask about a 400-page book and watch it read by section. | | Quotes that open on the page | Each claim in the answer quotes the sentence it came from, one click from the page — checked before you see it. How quotes are checked → | Ask the same question in each; try to land on the exact page in the assistant alone versus via the link. | | Edits you review, in the margin | Changes arrive as tracked changes you accept or reject; comments land on the sentence they are about. Edits wait for you → | Comment on a sentence; the proposal comes back on that sentence, with a reason. | | No credit cost for the link | The connection spends no MindMax credits — the assistant’s model does the work and bills as usual. | Run a full job through the link and check your MindMax credit balance is untouched. | | Does not carry over | | | | Phone or server-side reach | The server is local (127.0.0.1) and needs the desktop app running; a phone app or a server-side agent cannot reach your folder. | — | | A smarter model | The link lends tools and material, not intelligence. A weak model with a good map is still a weak model. | — | MCP facts last checked 2026-11 against the shipped desktop app and the /mcp/ guide.

A PDF in the chat assistant - Upload the papers into a chat or a project, a few at a time. - Ask the question and get a fluent paragraph. It is often right. - Before it goes into a draft, go back to the papers to find which parts are cited. You end withAn answer in the chat — but only the files you uploaded this turn, and the quotes are yours to verify. The same PDF, via the MCP link - Open the folder the twelve papers are already in, and connect the assistant. - Ask the same question; the assistant searches the whole folder, not just this turn’s files. - Each claim in the answer quotes the sentence it came from, one click from the page. You end withAn answer from the folder, each claim a click from its page, kept as a note beside the papers. ## Where the chat assistants is genuinely better - Anything that is not documents. They are general assistants. MindMax is not, and does not try to be. - Apps on your phone. All three have phone apps. The MCP link is to a desktop app, so for a one-off question on a phone, the assistant’s own app is the shorter path. - You already pay for one. A second tool has to earn its place for document work; the link lets you keep the assistant for everything else. - Files in their ecosystem. Gemini sits next to Google Drive, ChatGPT and Claude next to their own connectors. For files that live there, that is less friction than downloading them into a folder. ## Questions people ask ### Do I have to stop using ChatGPT, Claude or Gemini? No. The link adds a tool set the assistant can call; it keeps doing everything it did. For a one-off question, the upload flow still works exactly as before. ### Is this the same as the assistant’s own PDF reading? No, and it is meant to sit beside it. The assistant still reads what you upload; the link lets it read your whole folder, cite the page, and propose edits you review — without re-uploading anything. ### Does this use MindMax credits? No. Nothing on this path calls a MindMax model, so no credits are spent. The reading and reasoning are done by the model your assistant is signed in to, and billed there. ### Does it matter whether I use ChatGPT, Claude or Gemini? Not for what you get. The link is the same shape in all three: the assistant keeps the model you already chose, and MindMax adds the folder, the reading map and the review step. On Gemini the connection is made through its CLI, which is the part of Gemini that can load a local MCP server. ### Where do I start? Open the folder in MindMax, go to Settings → External AI, and press Connect. The app writes each host’s configuration and offers to restart it. See the connect guide for the two access levels. ## Starting without giving anything up Keep the assistant for everything it is good at. Connect it to the folder you already have, and let it call MindMax’s tools when a document question comes up. One click from Settings → External AI; disconnect the same way. Nothing is imported, nothing is locked in.
