AI writing tools for professionals
Memos, marketing copy and emails that read sharp and human — not like an AI first draft — with an honest before/after score on every rewrite.
- 01
The right register
Presets for business memos, marketing copy and email each carry their own rhythm and vocabulary, so a brief doesn't read like a landing page.
- 02
Fast, then refined
Humanize in one click, read the before/after AI score, and Push Further to refine only what's still flagged — no extra credit.
- 03
Free tools, paid core
The detector, grammar checker and summarizer are free and need no account. The humanizer runs on one-time credits — no subscription.
The tools you’ll reach for.
What people ask.
Which preset should I use for work writing?+
Business Memo for internal briefs and summaries, Marketing Copy for landing pages and ads, and Email for outreach and replies. Each is calibrated for that register.
Is there a subscription?+
No. snizzly uses one-time credit packs for the humanizer — no auto-renew. The detector, grammar checker and summarizer are free.
Will it keep names and figures correct?+
Yes. The humanizer preserves names, numbers and structure, and you can freeze specific terms so they're reproduced verbatim.
