Fireply AI

Replying in the right conversations is one of the most effective ways to grow on X, but doing it well takes hours every day. Fireply AI turns that into a set-and-forget workflow: it finds relevant posts in your niche and publishes replies that sound like you, on your own account.

You connect X through official OAuth; Fireply never asks for your password or 2FA. During setup, Fireply learns your writing style from your posts and builds an editable persona. You choose who it engages with by selecting accounts, X Lists or keywords, set content rules and operating hours, and can pause everything in one click.

Every reply is written from scratch for that conversation. Fireply reads images, threads and quoted posts, and uses human-paced volume with randomized intervals. Built for founders, brands, agencies and ghostwriters. New accounts start with 40 free automatic replies, no credit card.
