What is HyperWrite?

What it is

HyperWrite is an AI writing assistant from OthersideAI. It offers TypeAhead, an autocomplete that suggests the next words as you type in the browser, a chat assistant with web research and citations, custom personas, and a large catalogue of single-purpose AI tools for things like emails, essays, social posts and summaries.

Key features

TypeAhead autocomplete in the browser
AI chat with citations and real-time information
Custom personas to write in different voices (3 on Premium, 10 on Ultra)
Hundreds of task-specific AI writing tools
Early access to experimental features on Ultra

Models inside

HyperWrite's own pages say its main tools use OpenAI's GPT-4 and ChatGPT models, and that personas run on a custom Llama 3 70B model. It does not publish a current model list.

Pricing and rights

As of September 2026: the free plan includes limited monthly credits on basic AI (the exact limit is not stated). Premium costs $19.99/month or $192/year ($16/month) with 250 AI messages a month, 3 personas, citations and unlimited TypeAheads. Ultra costs $44.99/month or $348/year ($29/month) with unlimited AI messages and 10 personas. The pricing page does not describe output ownership; check the terms of service before commercial use.

Who it is for

People who write a lot in the browser (emails, posts, essays) and want autocomplete and quick research without switching apps. It can also suit students and job seekers who want quick help with essays, cover letters and emails in the browser. Heavy users should compare the Ultra price with general assistants, which now cover research, drafting and personas for a similar or lower cost.

Verdict

HyperWrite's TypeAhead and cited research are handy, but the message cap on Premium is low for the price, model details are dated, and general assistants now cover most of what it does. Try the free plan before paying.
