Ask any question about Blender, Python, Blenders Python module bpy or really anything else and receive context-aware responses. Whether you're a beginner or an expert, Chat Companion is your personal assistant for Blender. The AI usually gives you a detailed answer including python code and step by step instructions, depending on the context and task you give it.




The addon will automatically format the answer if there is any code or step-by-step instructions in it.



Each prompt and answer are stored in a history (the history will stay in a blend-file when you save and reopen it). You can mark each history entry as a favorite, rename them, delete them and clear the whole history while preserving favorites. You can also reorder history entries and specify if you would like a history item to be included as context in your next prompt or not!



Add attachments from disk or Blenders internal text files and append them to your prompts. This enables you to ask questions about attachments, append csv-data to build your script on, save your prompts as text files, and much more!




Execute directly from the answer, no copy-pasting necessary. And since the AI is not always perfect, you can also directly ask for a fix if there is an error in the script.




You can copy the code to your clipboard, a new text file or your current cursor location in a text file in Blender.




In the Blender Text Editor, right-click on one or multiple comment lines and ask for a code completion. The generated code will automatically be inserted into the text editor.



You can right-click on a lot of settings in the Blender User Interface to ask the AI about it. This will give you more information and also a python code example.




If you encounter any problems or errors, please contact me!

The addon uses the OpenAI API, so please go to https://platform.openai.com/account/api-keys to sign up and get your API key.


In order to use GPT-4, you need to have granted access to it by OpenAI, read here for more information: https://help.openai.com/en/articles/7102672-how-can-i-access-gpt-4


When you use the addon, you pay OpenAI (not me) for the tokens you use (https://openai.com/pricing)For all my testing during development so far I payed $1 in total, so it is very affordable. The Addon shows you the tokens for each prompt and for the current session. At the moment the prices for ChatGPT are $0.002 / 1000 tokens and GPT-4 costs $0.03 for prompt and $0.06 for completion / 1000 tokens.
