Makker

Version 0.9.0 · built to be used

Someone to think out loud with.

Makker is a chat on top of language models that stay in the EU or on your own server. Write, attach a document, pick a role, and get the answer as text, Word or PowerPoint. Open source, with a filter that stops personal data before it leaves the browser.

AGPL-3.0 · Passkeys and two-factor login · Export your data with one click

What you get

  • Write, and read the answer as it is written
  • Roles: sparring, pushback, plain language, teacher
  • Attach PDF, Word and text
  • The answer as Word or PowerPoint
  • Mistral in the EU or Ollama on your own machine
  • Conversations only you can see

Try it without creating anything

You get your own workspace with roles and tasks ready to use. It is deleted after 24 hours. No email, no sign-up.

Do not put real personal data in the demo. It passes through a database and possibly a language model on the way.

Open a demo

Think out loud with a model

Write the way you talk. Attach minutes or a draft, pick a role — sparring partner, devil's advocate, plain-language editor — and get an answer that stays. The model runs at Mistral in the EU or locally with Ollama.

Your data, always

Your conversations are yours: only you can see them, and you can take them out as a spreadsheet and JSON with one click. The workspace can be deleted completely again.

Secure from day one

Workspaces are separated in the database, not just in the code. Passkeys, two-factor login and a log that cannot be edited.
