TO READ AND EDIT

The structure stays readable.

Tables, task lists, code blocks, diagrams and formulas show up in the document. Switch to source whenever you need it.

TO STAY FOCUSED

Adjust the display to the document.

Pick a light or dark theme, your font and the text width. Reading mode keeps the document front and center.

Before you download

Questions before you install.

Can we work together in Marko?

Yes, with the Teams plan. Your organization gets its space, your shared documents show up in Marko next to your local files, with teams, roles and co-editing. Everyone signs in with their Marko account. On Solo, you work alone and pass your files around with the tools you already use.

Can I reuse documents my AI created?

Yes, as long as you have the text as Markdown. Save it in a .md file, then open it in Marko. You can also create a document and paste your text in Source mode.

Do I have to pay to try Marko?

No. The trial is complete for 14 days, with no account and no credit card. After that, Solo costs €5 excl. tax per month or €48 excl. tax per year. The Teams plan costs €9 excl. tax per seat per month, 3 seats minimum. If you connect an AI provider with your own key, that provider's billing, if any, is separate from Marko.

Are my documents sent to an AI automatically?

No. Files are read and saved on your Mac. For each request to the assistant, you pick the passage and the model, then check the preview before anything is sent. You can also work entirely without AI.

Which computers are supported?

The current download is for Apple Silicon Macs running macOS 12 or later. Windows and Linux versions are not available yet.

How do I install Marko?

Open the downloaded .dmg file, then drag Marko into Applications. The app is signed and notarized by Apple: the first time, macOS reminds you it came from the internet and you click “Open”. With Homebrew, one command is enough: brew install --cask merwanguerrib/marko/marko.
