HyperWrite

HyperWrite is an AI writing assistant from OthersideAI that offers in-line suggestions, automated replies, and research-backed content generation through a web app and Chrome extension. TypeAhead completes sentences as users type, and AutoWrite drafts full paragraphs from a short prompt. Email Response generates replies from minimal input, while HyperChat gives users a conversational interface for brainstorming and revising text. Scholar AI searches peer-reviewed academic articles so students and researchers can pull citations directly into a draft, and the Magic Editor rewrites or tightens existing writing. Users can also build custom AI tools or personas for recurring writing tasks, and the platform bundles hundreds of prebuilt tools such as summarizers and rewriters. The service targets students, professionals, and anyone handling a heavy volume of writing or email, from marketing copy to essays and reports. A limited free tier is available, alongside paid Premium ($19.99/month) and Ultra ($44.99/month) plans that raise or remove monthly AI-message limits and unlock more custom personas. Because HyperWrite works by integrating into Gmail and Google Docs rather than as a standalone editor, it depends on users already working within those tools, and like any generative writing tool its drafts still need human review before use.
