What is Reply Suggest?

Reply Suggest is a Chromium extension that suggests short replies while you browse. Today it works on X (Twitter) and Reddit. You connect your own AI provider and keys; we do not run a separate inference service for suggestions.

Which sites are supported?

x.com and twitter.com (posts), and reddit.com / *.reddit.com (threads). Sign in where required. More sites may be added later.

Which AI providers can I use?

OpenRouter, xAI Grok, Google Gemini, GitHub Models, and GitHub Copilot. Each has its own pricing, limits, and terms; you supply a valid key or token for the one you choose.

Where are my API keys stored?

In your browser via the extension’s storage APIs. They are not stored by this website’s operator. Generating a reply sends the relevant context to the provider you selected, under that provider’s policy.

How do I install the extension?

Use Add to Chrome here or the store listing in the Install section, then confirm the browser prompt. Open the popup, set provider and model, paste your key, save, then use Suggest on X or Reddit.
