Customize AI

Filo lets you define the exact instructions its AI follows when it writes Summaries, Drafts, Quick Replies and Smart Filter. One saved prompt = one consistent style across every message.


What you can tell it to do

  • •Shape summaries – "Summarize in 1–2 sentences" or "Return 3 bullet points with action items first."
  • •Tweak drafting tone – "Write polite but concise replies, ~120 words, end with 'Best regards,'."
  • •Force classification – "Always mark emails from boss@filomail.com as Important" or "Move messages containing 'invoice paid' to Updates."

Prompt-writing tips

  • •Be explicit and concise. Short, direct instructions work best.
  • •Include formatting cues. Markdown like bold, bullet lists, or numbered steps is respected.
  • •Combine rules freely. One prompt can cover summaries, drafts, and categorization in any order.

Example all-in-one prompt

• Summarise threads in 2 bullets; list action items first.
• Draft replies: friendly business tone, ≤120 words, end with "Best regards,".
• Auto-categorise any email from boss@example.com as Important.

Updating or resetting

  • •Edits apply instantly across every AI interaction.
  • •Delete your input to restore Filo's built-in prompt at any time.

Define it once—Filo handles the rest.
