Use tool ↗About HyperWrite
HyperWrite is a writing assistant that works in two places: a web app with chat, a document editor and a library of hundreds of prebuilt AI tools, and a Chrome extension that adds TypeAhead autocomplete and the same tools inside Gmail, Google Docs and other sites. It can search the web and scholarly papers and return citations with its drafts, lets users build custom tools and personas for repeat jobs, and reserves early access to experimental agent features for the top plan. It is aimed at students, researchers and professionals who write a lot of email and reports. A free account gets limited monthly credits on a basic model; Premium is $19.99 a month or $16 a month billed annually for 250 AI messages, and Ultra is $44.99 or $29 a month annually for unlimited messages. The operator is OthersideAI, Inc. of New York.

Pros & cons of HyperWrite
HyperWrite's useful part is the extension: autocomplete that follows you into Gmail and Google Docs, and a shelf of saved prompt tools you can trigger without opening a chat window. The web app is a competent but ordinary chat-plus-tools workspace in a market where Claude, ChatGPT and Gemini all now write and cite, so the question is whether the 250-message Premium quota and the in-browser convenience are worth $16 to $20 a month to you. The agent that once headlined the product survives only as an 'early access' line on the Ultra plan.
Pros
- Chrome extension brings autocomplete and tools into Gmail, Google Docs and most text fields
- Research mode returns citations from web and scholarly sources rather than unsourced prose
- Custom tools and personas let you package a repeatable prompt once and reuse it
- Annual billing cuts Premium to $16 a month, with a free tier to try first
Cons
- 250 AI messages a month on Premium is low for anyone using it as a daily chat assistant
- The free plan's limits are not stated beyond 'limited monthly credits'
- The browsing agent is no longer a shipped feature, only early access on Ultra
- No legal entity, address or country on the site beyond the OthersideAI brand name
Best for
- People who draft mostly in Gmail or Google Docs and want suggestions in place
- Students and researchers who want cited sources attached to drafts
- Anyone who repeats the same prompt jobs and wants them saved as one-click tools
Not for
- Heavy chat users, since Premium caps at 250 AI messages a month and unlimited costs $29 to $45
- Teams needing an API or shared workspace; it is sold per person with no developer access
Watch out: The $16 and $29 prices are annual commitments billed up front ($192 and $348); month-to-month is $19.99 and $44.99.
