1Stroke

1Stroke takes a narrow, practical view of AI writing: instead of opening a separate chatbot and pasting text back and forth, it puts the assistant where your words already live. Its tagline sums up the pitch — "the fastest way to craft meaningful replies anywhere on the web" — and its two core actions are Reply with AI and Rephrase with AI. Because it adapts to your own words and tone, the output is intended to sound like you rather than like a generic AI voice.

Support for "all websites" is the key differentiator. Many reply assistants are tied to a single inbox or social network; 1Stroke aims to work on whatever page you happen to be on, which covers email, social comments, review responses, and support threads in one extension. Setup is quick: install the extension, sign in through the app subdomain, and the assistant appears alongside the text fields you already use.

Pricing is deliberately simple and posted publicly on the site. The Free tier includes Reply with AI and Rephrase with AI across all supported websites but with limited power. Premium is listed at $7.50 per month billed monthly and adds customization, full power, and customer support. A Teams plan carries a custom annual price with membership and permission management, personalized customization help, training, and 7/7 support. The company also promotes a seven-day trial framed as "try now, pay later", so you can evaluate draft quality in your own workflow before subscribing.
