Cognira is an AI chat assistant that learns by itself. It runs independently on a single iMac using MLX inference. Users can teach Cognira preferences or facts during a conversation, and these are saved in private memory. They will be applied from the next reply. The hosted model, Cognira Retrain 12B, is based on Gemma 4 and does not use any external API. A local version called Cognira Entity runs the same models entirely on the user's hardware. Optional weight-level retraining is available. Developers can also access an OpenAI-compatible API endpoint for a token-based price.
