Through its Chrome extension, it offers TypeAhead suggestions that complete sentences as you type inside Gmail, Google Docs, and other web editors, alongside AutoWrite for generating paragraphs from a short instruction. An email responder drafts full replies from a few keywords, which is a common productivity win for people who live in their inbox. Beyond the assistant itself, the product ships a large library of pre-built tools covering rewriting, summarization, explaining complex topics in plain language, speeches, and more. Users can also assemble custom AI tools that chain steps together for repeated workflows. HyperWrite Scholar adds a research layer by searching scholarly articles and papers, so generated text can be grounded in current, citation-backed information rather than the assistant's memory alone. Pricing is subscription-based with a free entry point alongside paid tiers. Paid plans increase the monthly AI message allowance, unlock custom personas that mimic your writing style, and give unlimited TypeAhead suggestions. Higher tiers remove the message cap entirely and provide early access to experimental writing and agent features. **Pricing & Plans:** Freemium. A free tier introduces the assistant and a limited message allowance; Premium is listed around $19.99/month with 250 AI messages, citations, real-time info, and 3 custom personas; Ultra around $44.99/month adds unlimited AI messages, 10 personas, and early access to experimental features.
