Anyword vs Grammarly

Anyword is an AI copywriting platform for marketing teams, built around predicting which copy will perform before it is published. The company began in 2013 as Keywee, a New York and Tel Aviv startup that optimised social ad campaigns for publishers, and relaunched in March 2021 as Anyword after years of collecting ad performance data. Its core job is generating ads, emails, landing pages and social posts and scoring each variation for likely engagement or conversion.

Every piece of copy gets a Predictive Performance Score from 0 to 100 based on audience, channel and goal, and the editor updates predictions as you edit. Brand Voice stores tone, audiences and guidelines; Blog Wizard drafts long-form posts with a plagiarism check. Business and Enterprise tiers add custom models trained on your past copy, content intelligence against Anyword's A/B test dataset, automated website messaging tests and a Performance API that feeds predictions into your own AI agents. Self-serve plans start at $49 a month with a 7-day trial.

Anyword fits performance marketers and agencies that test lots of ad and email variants and care about conversion more than prose. It is pricier than general AI writers, prediction quotas are tight on lower plans, and the best features sit in custom-priced tiers. Jasper is stronger for brand-wide content operations, Copy.ai for GTM workflows, and ChatGPT alone is cheaper for occasional copy.

Anyword now positions itself as LLM-agnostic: its API and Chrome extension add performance scoring on top of ChatGPT, Gemini and Notion.

Grammarly is an AI writing assistant founded in 2009 in Kyiv, Ukraine, by Max Lytvyn, Alex Shevchenko and Dmytro Lider, now headquartered in San Francisco. It works wherever people write, through browser extensions, desktop apps for Windows and Mac, mobile keyboards and integrations with tools such as Google Docs, Microsoft Word and Outlook, checking text in real time as you type.

Beyond spelling and grammar, Grammarly flags clarity, conciseness, tone and engagement issues, rewrites whole sentences, adjusts formality, checks plagiarism and citations, and generates or edits text with AI prompts and agents. Business plans add company style guides, brand tones, snippets for reusable text, analytics and SSO. The free plan covers core corrections and a limited number of AI prompts; Pro adds full rewrites and more AI usage; Enterprise adds admin controls and security reviews.

After acquiring Coda in late 2024 and the email client Superhuman in 2025, the company began building a broader AI productivity suite, and in late 2025 it adopted the Superhuman name for the company while keeping Grammarly as a product brand. Grammarly remains strongest in English; in September 2025 it added beta support for Spanish, French, German, Italian and Portuguese, but Turkish is not among the supported writing languages. AI features built into Google Docs and Microsoft 365 cover basics for many users, and QuillBot is a popular, cheaper option for paraphrasing.
