The message rewriter is the “polish my draft” button inside customer conversations. You type a rough draft, tap the rewrite action, and the AI returns a cleaner version tuned to the channel.

​
When to use it

Use it when you have a draft already typed and you want the AI to fix tone, grammar, or length without inventing new content. The rewriter never adds new information that wasn’t already in your draft.

​
How it adapts to channel

The rewriter checks whether the conversation is SMS or email and applies different rules: SMS:
  • Tight, ideally under 320 characters
  • One or two short paragraphs at most
  • No formal greeting or sign-off
  • Conversational, first-name basis
Email:
  • Paragraphs allowed for readability
  • Natural greeting and sign-off only if your original had one
  • No subject line (your subject is handled separately)
  • No signature block (the app appends one)

​
What gets preserved

The rewriter is instructed to preserve facts exactly, including:
  • Prices, dates, addresses, names
  • Links (review request links, payment links, etc.)
  • The original intent and meaning of the message
It only fixes tone, grammar, awkward phrasing, and typos.

​
Extra instructions

You can pass an optional instruction along with the rewrite (e.g. “make it warmer,” “shorter,” “more apologetic”). The AI tries to honor it without altering facts.

​
What it does not do

  • Add information that wasn’t in your draft
  • Add a subject line for emails
  • Add a signature block
  • Wrap the output in quotes or commentary (it returns the rewritten body only)
  • Translate to another language (unless you ask in your extra instruction)

​
Cost

The rewriter uses a fast, low-cost model by default. Per-call cost is typically under a fraction of a cent.
