Fireply is an AI reply agent for X (Twitter). It learns your voice from your posts, watches the accounts and lists you choose, and posts timely, context-aware replies for you. It works through X’s official Contributor access, so your password is never shared.
Replies are written from scratch for each conversation, reading images, threads and quoted posts. You set content rules and a daily time window, and can pause everything in one click. Every new account gets 40 free replies, no credit card.
