Tools
Markdown tools that open already working
Every page below puts the tool at the top, with a sample document already loaded, and the explanation underneath. Nothing to install, nothing to sign up for, and the text never leaves your device.
Markdown Reader Long documents, with an outline and progress For manuals, specifications and course notes: a table of contents built from the headings, reading progress, and four ways to read the same file.
Open tool
AI Markdown Viewer The ChatGPT or Claude answer, formatted Paste the answer full of asterisks and hash marks and read it with headings, tables and code in place. Opens the downloaded .md file too.
Open tool
Markdown + Mermaid Diagrams drawn inside the document Flowcharts and sequence diagrams rendered where they sit in the text — the diagram stays versionable code, not an exported image.
Open tool
Markdown from URL A README straight from the repository address Paste the URL of a public .md file, the GitHub file page included, and read it formatted before cloning or committing.

What all four share
- They open ready. The editor arrives with a sample document loaded; edit over it, or clear it and paste your own.
- No account. No sign-up, no email, no usage limit.
- No upload. Reading and rendering happen in the browser; nothing is transmitted to a server of ours.
- They hand off to the full reader. One button passes the document to the reader, with the outline, progress, study cards and presentation mode.
Only the tools are available in English so far. The guides, the Markdown reference and the blog are still in Portuguese — the links in the header point at them, and they are marked as Portuguese so it is clear before you click.
