Personalization
Tell Asyncat about yourself and how you like answers, once, in Settings → Personalization.
Your preferences
Two short fields, up to 1,500 characters each:
| Field | What to put in it |
|---|---|
| What should Asyncat know about you? | Your work, what you're learning, the tools you use. For example: “I'm a nurse learning Python. I use Linux at home and Windows at work.” |
| How should Asyncat answer? | Length, tone, format, and the language and spelling you want. For example: “Keep answers short and plain. Use British spelling. Show one example.” |
Press Save, and your next message uses them. Discard drops changes you haven't saved.
Where they apply
Asyncat reads your preferences in every chat, Cat and Quick ask, including temporary chats, which only read them.
Claude Code, Codex and ACP agents don't get them: they are separate programs with their own settings. See Coding agents.
The instructions file
Under Advanced, the Instructions file sets who Asyncat's agent is, how it works and the rules it keeps. Most people never change it. In older versions it was called the soul.
- Edit… opens the file. Your edits are saved as your own copy, up to 20,000 characters; the file Asyncat came with stays as it is.
- The row says whether the file in use is the default or edited.
- Reset to default deletes your edits, and Asyncat goes back to the instructions it came with.
Your edited instructions file is included when you export everything, and removed when you delete everything. See Privacy & safety.
Other ways to shape answers
- A project's instructions apply to every chat in that project, such as “answer in British English, use metric units”. See Projects.
- An agent's instructions give it a role for one kind of job, such as a writing coach or a code reviewer. See Agents.
- Memories keep what Asyncat learned about you from your chats. See Memory.
