Replying in the right conversations is still 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. Sign-in is read access only. Replies go out through X's official Contributor permission on a dedicated contributor handle, so your own account never runs automation. You can revoke access in X at any time.
During setup, Fireply learns your writing style from your posts and builds a persona you can edit: tone, background and preferences. You choose who it engages with by selecting accounts, X Lists or keywords. Content rules let you block topics (for example "never discuss politics"). You set operating hours and can pause everything from the dashboard in one click. Once setup is done, Fireply runs on its own; you do not need to keep the tab open.
Every reply is written from scratch for that conversation. Fireply reads images, threads and quoted posts, and can pull live context such as market data and news when it helps the reply. Volume is bounded and human-paced, with randomized intervals and rest periods, so the account does not look like a blast bot.
Fireply is built for founders who want inbound from X, brands that want to show up in relevant threads, agencies and ghostwriters who manage multiple client voices, and technical builders who would rather ship than sit in reply tabs. Agencies get a separate voice and targeting set per account. Eligibility on the product side is a verified X account with at least 50 followers and recent activity.
New accounts start with 40 automatic replies on their own X account, no credit card. If you want to continue, paid plans are Growth at $69/month (20 replies/day), Advanced at $99/month (35 replies/day, most popular) and Scale at $129/month (50 replies/day). Yearly billing is available at a discount. Cancel anytime.
Alongside the product, Fireply publishes free browser tools for X at fireply.ai/tools, with no Fireply account required, and runs a 20% lifetime recurring affiliate program at fireply.ai/affiliates.
Safety is the architectural point: no password sharing, official Contributor access, editable persona, content rules, bounded volume, and a free trial long enough to audit reply quality before you pay.
