The writing assistant
It writes your emails, not your HTML
You describe your email in plain words. It returns a subject, a heading, paragraphs, and a button — blocks you edit one at a time.
- Editable blocks, not code
- Your voice, set once
- Web research, no extra charge
01
What it returns
Fix one block without touching the rest
Your email arrives split into blocks in the editor: the heading, each paragraph, the image, the button. Open the one that needs work; the others stay put.
- Outlook, Gmail, Apple Mail: the email arrives intact
- TitleLet's end the year together
- ParagraphFriday December 31, at 9 pm, we meet online for the last session of the year.
- Imagephoto of the last session
- ButtonReserve my spot
- Divider
- Space
Twenty at most.
02
Your voice
Set once, kept for all
Tone, length, register, and emojis: four settings you configure once for your whole workspace. A phrase in your request always overrides a setting.
Tone
Calm and clear, without stiffness. Facts, clean sentences, no familiarity.
Length
Register and emojis
The mindset
- 01
It writes. It does not send.
- 02
It never refuses. It leaves a bracket.
- 03
It searches. It does not guess.
- 04
It cannot see your subscribers.
- 05
It hands back control. Always.
03
Coming back to it
You revise, it rewrites the whole thing
'Shorten the second paragraph and use first names' is enough: it sends back the whole email corrected, not just the changed part.
- you
A letter to announce our summer hours, warm tone, short.
- l'assistant
Subject, preheader, and four blocks. The hours are in [brackets] — it doesn't know them.
- you
Shorten the second paragraph.
- assistant
Same text, that paragraph in two sentences. The rest stays.
- Never a required step: the editor stays yours
04
