X AI Assistant

X AI Assistant adds a small panel directly inside X's compose area. Pick a tone, click once, and get a ready-to-edit reply in seconds. What it actually does When you open a reply thread, the extension reads the post and drafts a response that fits the context, not a generic "Great point!" opener. The replies are short, direct, and written to sound like a person. You can copy, tweak, or regenerate before posting anything. Eight reply modes Support, Analyze, Witty, Inform, Question, Challenge, Humor, and Custom, each one steers the AI toward a different angle on the tweet. Works with the AI provider you already use Connect your own OpenAI, Anthropic, or Google key. Or subscribe to Pro and skip the API key entirely — the extension handles everything server-side. Pro plan — $6.99 / month 1,000 AI calls per month. No API key to manage. Cancel any time from inside the extension. Free plan 5 replies per day. Your own API key required. --- The extension only runs on x.com. It does not read your DMs, timeline, or any data outside the reply thread you're actively composing.
