Best Writing AI Agents

Writing agents at a glance
The 6 writing agents we track, listed alphabetically. 1 of the 6 publish a free tier. Prices are the vendor’s own published starting figure and change without notice — check the vendor’s pricing page before committing.
The bar under a price compares that plan with the dearest monthly plan in this table (3 of the 6 rows are flat monthly prices). Custom, per-seat, per-usage and annual prices are not on the same scale, so they carry no bar — a missing bar does not mean cheaper.

Copy.ai
$29/mo
The first thing to understand about Copy.ai is the gap in its price list. The self-serve Chat plan is $29 a month, or $24 a month billed annually, for up to five seats with unlimited chat words and a choice of OpenAI, Anthropic and Gemini models; the next step, Growth, is $1,000 a month billed as $12,000 a year, with 75 seats and 20,000 workflow credits (copy.ai/prices, read 16 October 2026). That gap tells you what the company is now: a go-to-market automation platform for sales and marketing teams, with the chat tier as the entry door. Where it earns the money is workflows — research an account, draft the sequence, update the CRM — not single pieces of copy, and the credits that meter those workflows are the number to watch. No free plan is listed, though the site offers a trial. If you want a writing assistant for articles, Writesonic or Notion AI on this site are closer fits; if you want prospect-level personalisation, Clay overlaps. Verdict: good for a revenue team that will build and run workflows every week; expensive for everyone else once you leave the Chat tier.
Declared features

Best for
Sales and marketing teams that want repeatable go-to-market workflows — account research, outbound sequences, CRM updates. Not for solo writers or small content teams, who will stay on the Chat tier and could get similar drafting elsewhere.

- OpenAI, Anthropic and Gemini models in one chat
- GTM workflows metered in credits
- Growth $1,000/mo billed annually, 75 seats
- Brand voice and sequence drafting
Writesonic
writing
Brands, agencies and in-house SEO teams that need to see and fix how AI assistants describe them. Not for freelancers who want a cheap article writer, or for sites too new to have any AI-answer footprint to track.
Notion AI
writing
Teams that already live in Notion and will pay for the Business plan to get meeting notes, database autofill and workspace search in one place. Not for individuals on the Free or Plus plan, who only get a trial of the AI, or for teams whose documents live elsewhere.
Sudowrite
writing
Novelists, screenwriters and serial-fiction writers who draft every week and want suggestions that stay in their voice. Not for business, academic or SEO writing, and not for someone who writes rarely, since you pay monthly for credits whether you use them or not.
Writer
writing
Marketing, content and communications teams in large or regulated companies that need output grounded in approved material and a consistent voice. Not for freelancers or small teams, or for anyone who wants a published price before a sales conversation.
Wordtune
writing
Students, professionals and non-native English writers who want quick alternatives for clumsy sentences in email, documents and the browser. Not for long-form drafting from scratch, for teams needing SSO, or for passing off AI-generated text as your own.
