1Stroke is a Chrome extension that drafts and rephrases replies inside any text field on the web, so emails, chats and reviews get a fast, on-tone first draft.
About 1Stroke
What Is 1Stroke
1Stroke is an AI writing assistant that lives in your browser. Instead of opening a separate chat window and pasting text back and forth, this AI reply generator lets you right-click a text box and pick Reply with AI or Rephrase. A suggestion appears where you're already typing, based on the conversation around it.
The tool targets a specific kind of friction. Most people can write, but they stall on the first sentence or spend too long polishing one. 1Stroke fills that gap without pulling you out of the page, which matters most for the messages you send dozens of times a day: customer replies, comments, direct messages, product reviews.
Two things set the limits. It only works on text you type on a website, so native desktop apps and mobile keyboards are out of scope. And it runs on Chrome as an extension, so it won't follow you to Firefox, Safari or a phone. The free tier also caps how much you can use it, and the company puts "limited power" on that plan rather than naming a hard number.
Getting Started
- Create an account on the 1Stroke site with an email address or a Google login.
- Add the 1Stroke extension to Chrome and pin it.
- Open any page with a reply box, click into the field, and right-click to find Reply with AI.
- Accept a suggestion, tweak it, or ask for a different take.
- Upgrade to Premium when you hit the free limits and want customization on top.

Key features
Reply with AI inside any text field
The core move is a right-click. You open the context menu on a text box and choose Reply with AI, and a relevant response appears in place. It reads the exchange around the field to shape the answer, so you're not feeding it a separate prompt. This is what removes the copy-paste loop that most AI tools still force on you.
Rephrase the text you already wrote
Rephrase takes what you typed and rewrites it in clearer language. It fits the moment when a sentence is close but not quite right and you'd rather not start over. The original meaning should survive the change, so it's a polish tool rather than a generator.
Tone and brand customization
Premium adds customization so replies match how you or your brand actually sound. A support team can hold to one voice across everyone's drafts, and a solo creator can keep replies from drifting into generic AI phrasing. The free plan leaves this out, which is the clearest line between the two tiers.
Works on any website
The extension runs on any site with a text input, so the same tool covers email clients, social platforms, comment sections and review forms. You don't install a separate integration for each one. The catch is that it's limited to fields you reach through the browser.
Chrome extension, no setup
Setup is adding one extension and signing in, with no configuration to maintain. That low overhead is the pitch for people who want help while writing rather than another dashboard to check. The trade-off is the hard dependency on Chrome.
Free to start, Premium when you need more
The free plan includes both Reply with AI and Rephrase across all supported sites, capped by a power limit the company doesn't spell out. Premium at $7.50 a month removes that cap, adds customization and unlocks customer support. Teams get their own plan with membership controls and onboarding help.
Pros and cons
Pros
- Lives inside the text field you're already using, so there's no tab switching or copy-pasting between tools.
- Reply with AI and Rephrase both work on the free plan, which lets you test the workflow before paying.
- Customization on Premium keeps replies in your tone, which matters for teams that need a consistent voice.
- Works on any website with a text box rather than needing a separate integration per platform.
Cons
- Runs only as a Chrome extension, so Firefox, Safari and phone users can't use it as is.
- Handles web text fields only, which rules out desktop apps, terminals and mobile messaging apps.
- The free plan is capped by an undisclosed power limit, so you can't tell in advance how far it will stretch.
- The company doesn't publish a public API, so any custom or programmatic integration is unclear.
