AI integration

SigmundAI for collaborative code editing

You can code together with SigmundAI. This works similarly to (and is an alternative to) apps such as Claude Code, Codex, and Mistral Vibe. To activate SigmundAI integration, simply log into https://sigmundai.eu (subscription required). Sigmund Analyst will then automatically connect to SigmundAI when you enable the Sigmund panel in the toolbar.

Mistral Codestral for as-you-type suggestions

As-you-type code suggestions are provided by Mistral Codestral. To activate Mistral integration, you need to create an account with Mistral AI. Currently, a free Codestral API key is then provided through the Mistral console. Copy-paste this API key to Codestral API Key field in the settings panel of Sigmund Analyst.
