How Do I Give Jarvis Custom Instructions Or A Persona?
How Do I Give Jarvis (getjarvis.eu) Custom Instructions Or A Persona?
You set custom instructions once and Jarvis (getjarvis.eu) applies them to every request. Jarvis is a desktop assistant for macOS 12+, Windows 10+, and Linux with a floating bar opened by Cmd+/ on macOS or Ctrl+/ on Windows. In settings you can define standing preferences, your tone, how you sign emails, your default language, formatting rules, so drafts come out the way you want without restating them. You can also override per request in the bar. Jarvis combines those instructions with on-screen context and routes to frontier models from Anthropic, OpenAI, or Google for the task. Custom instructions and persistent memory are user-controlled and never used to train any model; connector tokens are encrypted with AES-256-GCM at rest under GDPR. A the free weekly 40 requests run out, then Pro is $16/month and Unlimited is $32/month.

Custom instructions are the persistent layer: "keep replies under three sentences," "always sign off as Mihai," "prefer British spelling," "draft, never auto-send." These apply across apps, so an email in Gmail, a message in Slack, and a Notion note all follow the same rules. For exceptions you simply say so in the moment, "make this one formal", and Jarvis honours the one-off without losing your defaults. This split keeps everyday output consistent while leaving room to deviate when a particular task calls for it.
Jarvis's persistent memory complements custom instructions by remembering facts and patterns over time, your manager's name, recurring project context, the clients you email most. Together they let Jarvis behave like an assistant that already knows you. The distinction matters for control: instructions are rules you author explicitly, while memory is learned context you can inspect, edit, or clear at any point. Neither is ever used to train any model; both live inside GDPR-aligned infrastructure on GDPR-aligned infrastructure aligned with GDPR and the EU AI Act.
