Fireply AI
Managed AI agent that writes and posts replies on X in your own voice
Free trialfireply.aiUpdated
About Fireply AI
Fireply AI is a managed reply agent for X (formerly Twitter). After a user signs in with X, it builds an editable persona prompt from the account's profile and recent posts, then picks posts from the X Lists the user targets and writes replies in that voice. The replies are generated with Anthropic's Claude, using the persona, content rules, the target post's text and images, and optional live data contexts such as crypto prices, news and market calendars.
Best for
- Growing an X audience through steady replies on targeted accounts
- Keeping a consistent presence on X without manual replying
- Founder-led growth: Reply to relevant accounts in a founder's voice to build visibility on X.
- Crypto commentary: Use market data and news contexts to post timely replies on price and news threads.
- Coach and creator presence: Keep a fitness or wellness account active with replies within set content rules.
- Agency delivery: Run higher-volume reply schedules for client accounts on the Scale plan.
Not ideal for
- Users who want to write every reply themselves
- Users who need other social networks
- Accounts that cannot risk any platform enforcement action

Frequently asked questions
Does Fireply post from my own X account?
Not directly. A separate Fireply contributor handle posts the replies on your behalf through X's contributor access feature. You never share your password, and removing the contributor in X settings stops all activity.
Which AI model writes the replies?
Fireply says replies are generated by Claude from Anthropic, using your persona, content rules, optional data contexts and the target post's text and images.
Is there a free plan?
There is a one-time free trial of 40 replies per X account with no credit card. After that, a paid plan is needed. Unused trial replies carry over as bonus volume if you subscribe.
Can my account be restricted or banned?
Fireply says no client account has been suspended or banned because of the service, but its terms also state that no provider can guarantee how X applies its rules and that promotional or repetitive persona instructions can trigger X enforcement.
How much does it cost?
Paid plans are $69 a month for 20 replies a day, $99 for 35 a day and $129 for 50 a day. The terms describe a yearly option at 20% off.
Can I cancel?
Yes, through the dashboard. Cancellation takes effect at the end of the current paid cycle, and the terms state no refund for the current cycle.
