HyperWrite review

HyperWrite is a general AI writer rather than an email tool, but its Chrome extension makes it useful in webmail. TypeAheads suggest the next words as you type on any website, and paid plans make them unlimited. Premium, at $16 a month billed annually ($192 a year) or $19.99 monthly, includes 250 AI messages a month, citations with real-time information, three custom personas that help the AI write like you, and a library of hundreds of pre-made tools. Ultra, at $29 a month billed annually or $44.99 monthly, removes the message cap, raises personas to ten and gives early access to experimental features. A free account gets limited monthly credits on the basic AI model. Because HyperWrite does not connect to your inbox, it cannot sort mail, draft replies automatically or remind you to follow up. It fits people who want one writing assistant for email, posts and documents in the browser.
