Fireply

Features

• Replies in your voice. Fireply learns your writing style from your existing posts, and you can edit the persona's tone, background and preferences at any time. Replies draw on the full post (including images), real-time data and a knowledge base set up for you. Official source 1 ↗ · Official source 2 ↗
• Three ways to target. Point it at keyword searches to reach people describing a problem your product solves, at reply lists of creators whose audiences you want to reach, or at follow-for-follow conversations to grow a verified following. Official source 1 ↗
• Post selection and filtering. It picks posts that are already getting traction and skips spam, NSFW content, reposts and duplicates, as well as tragic, political and identity-related topics. The filter is automated and best-effort. Official source 1 ↗ · Official source 2 ↗
• Automatic publishing on a schedule. Replies are published automatically throughout your chosen operating hours, without keeping the dashboard open; daily counts ramp up gradually, but the plan's monthly volume is guaranteed. Official source 1 ↗ · Official source 2 ↗
• Dashboard and pause control. A dashboard shows profile visits and followers, published replies and the upcoming queue, and lets you change targeting or pause replies. Removing the contributor account in X stops the agent immediately. Official source 1 ↗ · Official source 2 ↗
• Multiple accounts for agencies. Agencies can run it for clients, with a separate voice and targeting for each account. Official source 1 ↗

Best for & limitations

A founder replying to people on X who describe a problem their product solves, so those people find the product through the founder's profile. Official source 1 ↗

A creator or expert who wants steady replies under bigger accounts in their niche to grow followers, without spending hours a day on X. Official source 1 ↗

A social media agency running reply activity for several client accounts, each with its own voice and targets. Official source 1 ↗

• Your X account carries the risk. Automated replies, especially promotional ones with links or repeated phrasing, can trigger X shadowbans, reduced reach, rate limits or suspension. Fireply says it cannot guarantee how X applies its rules and accepts no liability for those outcomes; the service is built to mirror natural engagement patterns. Official source 1 ↗
• You are responsible for every reply. Replies are published under your name and you are solely responsible for them. Fireply does not guarantee that each reply is factually accurate, and its topic filter is best-effort. Official source 1 ↗
• Replies are not labelled as automated. Nothing in the described workflow marks replies as AI-written: they are published in your voice on your account. The terms forbid using the service for inauthentic or coordinated behaviour that breaks X's platform-manipulation rules, so check X's automation rules for your use.

• No refunds after a cycle starts. Plans are prepaid and cancellation only stops the next renewal; the terms also ask both parties to keep the arrangement confidential. Official source 1 ↗
• Setup data kept indefinitely. Workflows, configuration and reply history are kept indefinitely unless you ask for deletion. Official source 1 ↗
