Personalization
Demi adapts to your communication style, work habits, and preferences. The more it knows about you, the less you have to explain every time you ask for help.

How Demi Learns Your Style
Most AI assistants give you generic, one-size-fits-all responses. Demi is different. During onboarding, you tell Demi about yourself — your role, how you like to communicate, and how much independence you want it to have. From that point forward, every email it drafts, every report it builds, and every response it gives reflects your personal style.
You can adjust your personalization settings anytime by going to Settings → Personalization on your iPhone app. Changes take effect immediately, so feel free to fine-tune things as you and Demi get to know each other.
What You Can Customize
Communication Style
Choose between concise and detailed responses, formal and casual tone, or technical and simple language. Demi matches whichever style feels right for you.
Autonomy Level
Decide how proactive Demi should be. Want it to handle things on its own? Or would you rather it ask before acting? You set the boundaries.
Work Context
Tell Demi about your role, your industry, and your key responsibilities. This helps it prioritize the right information and draft messages that fit your professional world.
Writing Voice
Share sample writing, preferred greetings and sign-offs, emoji preferences, and any custom phrases you use regularly. Demi mirrors your voice so emails sound like you wrote them.
Custom Instructions
Beyond the built-in preferences, you can write specific rules that Demi should always follow. These custom instructions act as standing orders — things like "always CC my manager on client emails," "keep reports under two pages," or "never schedule meetings before 10 AM."
Custom instructions are powerful because they encode your workflow knowledge into Demi permanently. You set them once and Demi remembers, so you never have to repeat yourself.
How Personalization Affects Demi
Your preferences shape every interaction. Here is how each setting translates into real behavior:
- Email tone — Demi drafts emails that match your communication style. A concise, casual setting produces short and friendly messages. A detailed, formal setting produces thorough and professional correspondence.
- Report formatting — Spreadsheets and summaries follow the level of detail you prefer. Ask for technical output and Demi includes data points and sources. Ask for simple output and it gives you the highlights.
- Response length — Chat responses, research summaries, and briefings adjust to your preferred depth. No more wading through paragraphs when a sentence will do.
- Proactivity — If you set a high autonomy level, Demi handles routine tasks without asking. If you prefer to stay hands-on, it checks in before every action.
Best Results
Provide sample writing for the best personalization results. Paste a few emails you have sent in the Writing Voice section and Demi will analyze your tone, vocabulary, and structure. The more examples you give it, the more naturally it writes on your behalf.
