Anyword vs Lex

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.

Lex is a minimalist word processor with AI built into the writing experience. It was created by Nathan Baschez at Every, the media and software company, and later spun out as an independent company. Instead of a chatbot in a sidebar, Lex puts AI inside a calm, distraction-free editor where writers ask for feedback, rewrites, research or continuation directly on their draft.

Writers can highlight a passage and request alternatives, ask the AI to check an argument or suggest titles, and save custom prompts for repeated tasks. Drafts can be shared for comments, and version history tracks changes over time. Lex works with large language models from several providers, and users can choose which model handles their requests. Lex is no longer accepting new customers, and its pricing page shows plan details only to existing users.

Lex suits essayists, newsletter writers, founders writing memos and anyone who wants an editor that helps them think rather than write for them. Formatting options are limited, integrations are few and it is not built for long structured documents or team workflows. Google Docs with Gemini and Notion AI are better for collaborative documents, while iA Writer is a focused editor for writers who do not want AI in the loop.
