Quick overview

What is MindMax Online Editor?

The comprehensive upgrade of the FunBlocks Markdown editor — built to turn AI answers and Markdown into documents you can actually hand in.

✨

What makes it different?

Paste an AI answer, refine it like a document, export a Word file that holds up — formulas editable, tables real.

🎯

Who is it for?

Students, researchers, writers, PMs — anyone who pastes ChatGPT or Claude answers and needs a clean .docx or PDF out the other end.

💰

Is it free?

Yes. Write, edit, and export without an account or watermark. AI extras need a free login.

🧩

What can it do?

WYSIWYG Markdown, slash blocks, math, tables, Mermaid — then export Word, PDF, images, or open and save your own .md files.

Looks familiar

Like Word or Notion — nothing to learn

Type / for blocks and AI. Tables behave like tables. Formulas and Mermaid preview while you type. Paste from the web and get clean Markdown.

  • Slash menu & block handles
    Insert headings, todos, tables, callouts, code, formulas, or charts — drag any block to reorder.
  • Tables you can actually edit
    Resize columns, reorder rows, sort by a column, paste from Excel — still plain Markdown underneath.
  • Live preview as you type
    LaTeX formulas and Mermaid diagrams render beside the source, so you see the result immediately.
Free account unlocks

Go further with AI

Editing and export work without login. These need a free MindMax account.

Diagrams from text

Select or paste a passage, pick a diagram type, and AI draws it — every node links back to the sentence it came from.

  • Mind maps, flowcharts, timelines, and infographics from plain text
  • Each node links back to the sentence it came from
  • Regenerate or edit the diagram without losing the source text

AI rewrites you approve

Ask AI to tighten, expand, rephrase, or translate. Every change arrives as a revision you accept or reject.

  • Polish, expand, shorten, translate, or fix grammar on any selection
  • Changes show up as tracked revisions — nothing is silently overwritten
  • Accept, reject, or restore a previous version in one click

Share for comments

Send the draft as a link. Reviewers comment on paragraphs without an account; comments land back in your document.

  • Share a review link — no account needed on their side
  • Comment on any paragraph, right where the wording matters
  • Comments return to your document so you can revise in place
Editor

What the editor does

One document, from the first paste to the file you send out.

AI answers paste cleanly

Formulas written with \( \) and \[ \] convert on paste. Content copied from the web arrives as clean Markdown — no stray asterisks or hashes.

Write like a document

Headings, lists, tables, callouts, code, formulas, highlights, emoji — formatted as you type. Press / to insert any block.

Word export that holds up

Formulas become native, editable Word equations. Tables are real cells. Mermaid diagrams go in as images.

PDF, Markdown, images, rich text

Print to PDF, download .md, export image cards, or copy formatted content into email and Feishu.

Your own .md files

Open Markdown files from your computer and save them back. Pasted or dragged images travel with the document.

Stays in your browser

Documents live in this browser’s own storage, listed in the sidebar. Editing and exporting upload nothing.

Honest boundaries

Where it falls short

Better to know now than after you rely on it.

  • Docs live in this browser

    Clearing site data or switching devices loses them. Export what you want to keep — you can export everything at once.

  • One document at a time

    No backlinks or folder vaults here. To work across a whole folder of PDFs and notes, use the desktop app.

  • Export is one-way

    Changes made later in .docx do not flow back. Finish editing first, then export.

  • AI needs an account and network

    Editing and export do not depend on the server. Diagrams, AI rewrites, and review links need login.

Prefer the original?

Looking for the classic FunBlocks Markdown editor?

MindMax Editor is a ground-up redesign of the FunBlocks Markdown editor — clearer writing experience, stronger export, and AI you can approve. If you still need the original editor, it remains available here.
