Best AI Writing Tools in 2026

ChatGPT is OpenAI's conversational assistant and the most general tool in this list: it drafts, edits, summarises and translates text in response to plain-language instructions. Its pricing page lists four consumer tiers. The Free tier includes unlimited text chats subject to abuse guardrails; Go adds more messages, uploads and longer memory and may include advertising; Plus adds advanced reasoning models, projects, custom GPTs and scheduled tasks; and Pro adds Pro reasoning, maximum deep research and monthly API credits. The page did not display dollar amounts when accessed for this review, so prices are omitted here. For writers, the relevant features are projects, which keep related documents and instructions together, memory, and deep research for source-gathering before drafting.

Claude is the AI assistant developed by Anthropic, which describes itself as a public benefit corporation. Writers use it for drafting, editing and working with long documents, and its Artifacts and Projects features keep drafts and reference material together. The pricing page lists a Free plan with limited usage every five hours; Pro at US$20 a month (US$17 billed annually) adding more models, Projects and Research; Max at US$100 a month with five times Pro usage; and Ultra at US$200 a month. Team seats cost US$25 a month billed monthly (US$20 annually) for teams of 2 to 150, and Enterprise is US$20 per seat billed annually with a 20-seat minimum plus usage at API rates.

Gemini is Google's AI assistant, available as a standalone app and inside Google Workspace applications. Its main distinction for writers is integration: Google's subscription page lists "Gemini in Gmail, Docs and more" on the Google AI Pro plan at US$19.99 a month, which helps with writing and organising directly in those apps, while the US$4.99 Google AI Plus plan lists Gemini in Gmail and Vids. The free plan offers the Gemini app without the Workspace integrations. Because drafts are produced where documents and emails are already stored, the assistant avoids the copy-and-paste step required by standalone tools.

Grammarly checks spelling, grammar, tone and clarity as users type and offers full-sentence rewrites. On 29 October 2025 the company renamed itself Superhuman, after acquiring the Superhuman email client in July 2025; the Grammarly product kept its name and now sits alongside Coda and Superhuman Mail, with a new assistant called Superhuman Go. The plans page lists a Free tier with 100 AI prompts a month; Pro at US$12 with rewrites, tone adjustment, plagiarism and AI-text detection and 2,000 AI prompts per member a month; and a custom-priced Enterprise tier, sold through Superhuman Go, adding unlimited prompts, SSO and data loss prevention.

Jasper is designed for marketing teams that need content to follow a consistent brand voice. The Pro plan costs US$69 per seat a month billed monthly or US$59 billed yearly, with a 7-day free trial, and includes Jasper's Canvas workspace, agents for core marketing workflows, two Brand Voices, five Knowledge assets and three Audiences. The Business plan is custom-priced with a 12-month minimum and adds agents for generative-engine optimisation, translation and deep research, a no-code custom agent builder, the Jasper Grid, unlimited brand assets, API access and admin controls.

Copy.ai combines a chat interface for copywriting with workflow automation aimed at sales and marketing operations. Its Chat plan costs US$29 a month (US$24 billed annually) for five seats with unlimited words and access to models from OpenAI, Anthropic and Google. Above that, pricing jumps to workflow plans billed annually: Growth at US$1,000 a month for 75 seats and 20,000 workflow credits, Expansion at US$2,000 for 150 seats and Scale at US$3,000 for 200 seats, with Enterprise priced on request. The site's support links point to the fullcast.com domain, while the copyright line reads CopyAI, Inc.

Notion AI adds drafting, summarising and question-answering to Notion's documents and databases, so text can be generated next to the notes and project pages it draws on. Notion's pricing page lists Notion AI only as a trial on the Free (US$0) and Plus (US$10 per member a month) plans; it is included on Business at US$20 per member a month together with Notion Agent, AI Meeting Notes and Enterprise Search, and on custom-priced Enterprise plans. Custom Agents are billed separately at US$10 per 1,000 monthly Notion credits after a free trial.

Sudowrite is built for novelists and other fiction writers rather than business users. Its features include style matching, series continuity, AI chat and its own Muse and Ballad models alongside more than 30 other models. The Hobby & Student plan costs US$10 a month with 225,000 credits; Professional costs US$22 and adds developmental edits, line edits and beta reads; and Max costs US$44 with 2,000,000 credits that roll over for 12 months.

ProWritingAid analyses drafts through more than 25 writing reports covering style, pacing, repetition and readability, and has added AI features such as Rephrase, Chapter Critique and Story Canvas. The Free plan offers limited daily use. Premium costs US$30 a month or US$120 a year, and Premium Pro US$36 a month or US$144 a year; both are also sold as one-time lifetime licences at US$399 and US$699. Premium Pro adds daily chapter critiques plus live workshops, group critique sessions and cowriting sprints.

Wordtune, operated by AI21 Labs, focuses on rewriting sentences, suggesting alternatives and summarising documents rather than generating full drafts. The free Basic plan allows 10 rewrites a day and three summaries a month. Advanced costs US$6.99 a month (US$4.89 billed annually) with 30 rewrites a day, and Unlimited costs US$9.99 a month (US$6.99 annually) with no rewrite or summary caps. Paid plans carry a three-day trial and a 30% discount for students, educators and nonprofit staff, and Wordtune states that it does not offer refunds.
