A desktop workspace for reading, thinking and writing, with AI built in
It reads the whole document, and every answer quotes the page it came from — one click opens the source with that sentence highlighted.
- Open a folder you already have — PDFs, EPUBs, Word files and notes, nothing imported or copied
- Nothing to learn first: say what you want — “translate this PDF”, “write a report from these papers”
- Even without AI, it’s an editor you’ll enjoy writing in, whether it’s quick notes or full documents — and your files stay plain Markdown
Free app · pay only for the AI you use, or bring your own key
This is all you need to start. The rest can wait until you need it.
Open a folder you already have
Papers, notes, an Obsidian vault. Nothing is imported, copied or converted.
Ask it the way you’d ask a person
No commands to learn, no indexing to wait for.
Click a quote in the answer
It opens the source and highlights the sentence. That is when you know whether to trust it.

Your folder
Put AI to work in a folder you already have.
Nothing to move, nothing to set up. Point it at any folder on your disk — this year's project, a decade of papers, an Obsidian vault — and those files become something you can ask, argue with and add to.

Read
Finish the four-hundred-page book, with notes down the margin and a write-up at the end.
PDFs, books and slides open as themselves, and the AI works on the page you are reading.
Have it read along
Tell it why you are reading — to get your bearings, to review it, to find the weak spots, or to learn it — and it works through every chapter, leaving notes in the margin and, at the end, a summary of what is worth taking away, the strongest open question and what to pursue next.
Ask a region, or the whole thing
Box a chart, a table or an equation and ask about just that. Or ask about all of it — a short paper goes to the model whole; a long book is navigated chapter by chapter.
Every quote is checkable
Every conclusion carries verbatim quotes, and one click takes you back to the page it came from. You do not have to trust it — you can check it.
From your folderAsk across the whole folder at once — notes, papers and books together, not one upload at a time.
Think
A mind map you don't have to fill in yourself.
Angles side by side, five levels down and the way back still in view — a map was always the right shape for thinking. But a blank one only holds what you already thought of.
Now the agent grows it for you.Branches you hadn't thought of, laid out first. Dig into the ones worth it.
How it works
Pick a thinking model instead of typing a branch. The branch comes back with that method carried out on your own documents.
- SCAMPER
- Six Thinking Hats
- First Principles
- Trade-off Matrix
- Red Team
- Diverge
- Dig deeper
- Critique
- Structure
- Converge
- Learn
Knowing the list was never the hard part; remembering the right one at the right moment, and then actually grinding through it, is.
From what you are readingOpen a canvas beside the paper, the chapter or the figure you have open, and start from the passage you selected rather than a blank centre. Reading as a mind map →
Write
From scattered notes to a report, a thesis or a book that argues one thing.
You bring the half-formed ideas, the reading pile and the branch you liked on the canvas. It comes back with an outline — and once you have approved that, it writes the whole thing, section by section, or part by part for a book.
Nothing is drafted before you approve the outline
Send it back with comments on particular sections. An outline you already arranged on the canvas can go straight in.
In a long draft, chapter nine still remembers chapter two
It keeps a record of what the draft has already argued, so later chapters never contradict earlier ones.
It revises from your comments
Leave comments on the draft and it revises from them — every edit marked against what you had, for you to accept or reject.
From your folderThe finished piece is saved back into the folder as a file — material for the next thing you ask.
Revise
Hand it the draft you wrote. Review its edits like a colleague’s.
The report you finished last night, the chapter going to your supervisor, the email that runs too long. Say what you want, or leave comments in the margin — every change comes back marked on your own text, and nothing is saved until you accept it.
Three ways to ask
01Select a passage, say what to change
Tighten it, make it clearer, change the tone. The suggestion appears in place, as one change to accept or reject.
02Ask for a pass over the whole document
“Make it more concise and keep my voice.” Edits come back across every section, in groups you take one at a time.
03Leave comments, then revise from all of them
Comment the way you would for a colleague. Each group of edits says which comment it answers.
Your draft
- .md
- .docx
Accepted edits land in the same file — in a .docx, as Word tracked changes.
Markdown notes are edited in place, whoever wrote them; a PDF gets an editable .md copy beside it.

- AI drafts comments
- You keep the good ones
- Word comments in a copy of their file
They get their file back with your notes on the exact passages; the original stays untouched.
AI document review →Marked on your own text
Not a new copy to reread. Deletions struck through, additions highlighted; anything unmarked is exactly what you wrote.
Grouped, with a reason
Longer revisions arrive in groups, each saying why. Accept or reject a group at a time; a suggestion at the cursor is one decision.
Nothing lands until you say so
The file is untouched until you accept. What you accept goes into the document’s history, so you can still step back.
The same review covers every AI edit in the app — including drafts it wrote for you.
The editor
The notes app you were going to install anyway.
Your .md files stay plain text, linked the way you already link them — and the AI turns up where your cursor is, not in a sidebar you have to copy things out of.
Written the way you would write it anyway
[[Links]]with backlinks, an outline and daily notes — on files that stay plain text.- Press
/for headings, tables, callouts, code, math or a diagram; drag any block by its handle. - Open the same folder in any other Markdown editor and it reads the same.
AI at the cursor, without leaving the page
- Select any text and tell MindMax what to do with it — tighten it, expand it, change the tone, translate it, turn it into a list or a table, or clean up a messy paste.
- Ask it to keep drafting the next section, or to sketch an outline from where you left off.
- Request a flowchart, quadrant chart or infographic, and it's drawn right inside the note — as editable Mermaid or SVG.
No copying into a chat window and back.
Opens on the notes folder you already have — nothing to import, nothing converted.
There is more
And the parts you haven't seen yet.
The words under the box travel with it, so numbers come from the text, not the picture. The same box works in PDFs, books, slides and images.
Each page explained as the speaker would have; box the part you missed and ask until it makes sense, every answer pointing back to its slide.
Screenshots, photographed pages and diagrams: view them, box part of one, ask — or turn it into a Markdown table, outline or LaTeX.
Recognition you start on purpose and audit page by page, so a bad scan shows up now, not inside a quotation later.
A skill is a page of plain text saying how a recurring job is done. The same one runs in chat, on the canvas, or on a selection.
Start it once and it works through all 300 pages holding one set of terms — checkpointed, and read against the original.
Your thought written down correctly and filed under the right heading — nothing added, nothing dropped — and the note tidied when you ask.
AI writes in Markdown; your readers open Word. Answers from here or from ChatGPT and Claude leave as Word, PDF or image cards — real tables, editable equations.

Where to start
Pick a first job — a few seconds or an afternoon.
Say each decision as it happens; the AI spells it right and files it under its heading. On Friday, the update drafts itself.
Open it, get oriented, and come out able to say what it actually claims.
An outline you approved, edits you accepted, and a Word file whose citations still quote the page.
The real options on one ruler, what each one gives up, and a memo with a first action.
Start with a folder you already have.
