Most writing problems are tone problems. The information is right; the delivery is off. An AI keyboard rewrites the delivery in 3 taps.

Tone is what makes the same message land or bounce. A "send me the file" reads differently from a "would you mind sending the file when you get a chance?" Same information, different reception. Tone presets give you 8 different deliveries on demand.

How to do it with KeyAI

  1. 1

    Write the draft in your real voice

    Don't worry about polish — write what you actually mean.

  2. 2

    Select the text

    Tap and hold to select.

  3. 3

    Tap Tone, choose a preset

    Friendly / Professional / Confident / Apologetic / Concise / Detailed / Persuasive / Casual. The selected text is replaced in place.

  4. 4

    Layer a second preset if needed

    For nuanced shifts: Professional + Apologetic for customer support; Confident + Concise for proposals.

  5. 5

    Read before sending

    AI tone rewrites occasionally over-soften or add politeness you didn't intend. Always do a quick read pass.

Example

Before
"This is the third time I've explained this. Please read the doc."
After (with KeyAI)
"All of this is in the doc — let me know if a specific section is unclear and I can dig in there."
Tone → Friendly preserves the firmness but removes the frustration tone. Reply rate roughly doubles in tests like this.

Tips

  • • Tone → Concise on any draft over 100 words.
  • • Tone → Apologetic for support replies, even when you weren't at fault — softens the receive.
  • • Tone → Confident removes hedging ("I think", "maybe") for sales/leadership comms.
  • • Avoid Tone → Vulnerable for transactional messages — it lands awkward.
