Best AI for Drafting Emails

Drafting emails is one of the highest-friction knowledge work tasks — the cognitive gap between 'what you want to say' and 'formatted email' is large. The best AI for email drafting closes that gap: you speak the gist, AI produces the email.

WHAT TO LOOK FOR

The three things that actually matter

1

Voice to email draft

Speak the intent and key points. Lucy produces a complete, formatted email ready to paste and send — subject line, body, appropriate closing.

2

Tone calibration

Tell Lucy the relationship (close colleague, new client, senior stakeholder) and the tone adjusts — from casual to formal, direct to diplomatic.

3

Context-aware drafting

Lucy remembers your ongoing relationships and projects. 'Draft a follow-up to Sarah about the contract' produces a contextually appropriate email without re-explaining the history.

TLDR:Tell Lucy what you want to communicate — who it is to, the key points, the tone — and it drafts the email by voice. No opening Gmail, no staring at a blank subject line. Speak it, get the draft, copy and send.
