# Writing Style

Filo supports setting a **Writing Style** for AI email writing. Define it once, and Filo will follow your preferences for both new emails and replies—syncing across your account.

* * *

### Where to find it

- •**Mac & Windows:** Settings → Writing Style; you can also pick a style from the bottom of the composer.
- •**iOS & Android:** Settings → Writing Style; when composing/replying, pick a style from the toolbar above the keyboard.

* * *

### Built-in presets

Besides **Default**, Filo includes three built-in presets so you can quickly switch tones for different situations:

- •**Concise:** Shorter and more direct, with fewer pleasantries and less repetition. Prioritizes key points.
- •**Professional:** Polished business writing with clear structure and careful wording.
- •**Friendly:** Warm and natural, slightly more conversational while staying professional.

* * *

### Create your own style

You can also create custom writing styles, for example:

- •**Control tone & length:** “Polite but concise, ~120 words, end with ‘Best regards,’”
- •**Control structure & format:** “Start with the conclusion, then list action items as 3 bullet points; use bullets when needed.”
- •**Standardize wording:** “Avoid exaggerated adjectives; prefer active voice; keep key facts and numbers.”

* * *

### Style prompt tips

- •**Be specific, short, and actionable:** the more concrete, the more consistent the outputs.
- •**Give formatting cues:** e.g. “use bullets/numbering” or “first line is the conclusion.”
- •**Combine multiple rules:** one prompt can constrain tone, length, structure, and wording at once.

* * *

### Example

**Name:** Business-friendly · Action items first

**Style Prompt:**

```
New email: business-friendly tone, ≤120 words. Start with the conclusion, then list 2–3 action items (action items first).
Rewrite/polish: do not change facts, numbers, dates, or amounts; be clearer and shorter; avoid exclamation marks and hype.
Output format: prefer bullet points; use short headings when helpful; keep proper nouns and email addresses unchanged.
```

* * *

### Updating & resetting

- •**Applies immediately:** your next AI draft/rewrite will use the latest style.
- •**Back to default:** in the composer, choose **Default** (or unselect your current style) to return to Filo’s default writing.
- •**Manage multiple styles:** create/edit/delete styles and switch any time when writing.
