First Impressions and Onboarding
Upon visiting the Hiwriter website at hiwriter.rebump.cc, I found a clean, single-page pitch that immediately highlights the core value: GPT now in Gmail. The call-to-action directs you to the Google Workspace Marketplace for a one-click install. I installed the extension and was guided through a brief setup—granting permissions for Gmail access, which is standard for such add-ons. The dashboard appears as a sidebar within Gmail, with fields for email topic, recipient details, and a dropdown for style and tone. The interface is minimal and unobtrusive, which I appreciate because it doesn't clutter the native Gmail experience. The onboarding is essentially frictionless; you can start generating emails within seconds of installation. Notably, there is no account creation wall—you only need a Google account, and the tool works immediately.
Core Features and Performance
Hiwriter leverages OpenAI’s GPT-3.5 (the same model behind ChatGPT) to draft emails from scratch or reply within an existing thread. I tested the free tier by generating a follow-up email for a project proposal. I entered a brief topic, a few details about the recipient, and selected a professional tone. The generated email was coherent, contextually accurate, and required only minor edits. The reply generator uses the thread’s context to propose a response, which saved me the mental load of re-reading the conversation. The style and tone selector offers options like formal, friendly, persuasive, and short—each altering the output noticeably. The translate feature works well for multilingual use; I wrote an email in English and had it translated into Spanish for a client. The regenerate button provides up to five variations, allowing you to pick the best fit. One limitation I observed: the tool does not allow fine-grained control over paragraph structure or specific formatting like bullet points. For highly technical or lengthy emails, it sometimes generates verbose text that needs trimming. Also, the “Improve feature” is marked as coming soon, so you cannot yet polish your own drafts through the tool.
Pricing and Market Positioning
Hiwriter is positioned as a free tool in the Google Workspace Marketplace, and the website does not list any premium tiers or usage quotas. Pricing is not publicly listed on the website—it appears to be completely free to use within Gmail, though there may be invisible rate limits tied to OpenAI API usage. Competitors like Sidekick or Text Blaze offer similar automation but often require subscription fees for advanced features. Hiwriter’s focus is purely on email generation, whereas tools like Jasper target broader content creation. For email-specific tasks, Hiwriter is refreshingly straightforward and doesn’t push upsells. However, if you need a comprehensive writing assistant for documents, social media, or long-form content, you should look elsewhere. The tool’s reliance on GPT-3.5 rather than GPT-4 means output quality is slightly lower than state-of-the-art, but for everyday email writing it is more than sufficient.
Verdict: Who Should Use Hiwriter?
Strengths: Hiwriter excels at speed and simplicity. It reduces cognitive load for repetitive email tasks, works on mobile and desktop, and supports multiple languages. The regeneration and translation features are genuinely useful for international communication. Limitations: The lack of formatting control and the unavailability of the Improve feature (still pending) mean you may need to manually polish some outputs. Also, the tool requires internet access and a Google account, which could be a barrier for offline use or alternative email clients. I recommend Hiwriter to professionals who send a high volume of emails daily—sales reps, customer support agents, or busy managers—and want to cut drafting time. Casual users will also enjoy the convenience of instantly generating polite replies. If you need deep customization or work outside Gmail, consider alternatives like Grammarly’s tone suggestions or ChatGPT’s manual prompts. Hiwriter does exactly what it promises: never struggle to write an email again, and for that, it earns a solid place in any Gmail user’s toolkit.
