F5Bot sends free email alerts for Reddit mentions. Replymer is the professional upgrade — adding AI reply generation, one-click publishing, and a full marketing dashboard.
F5Bot is a great starting point for keyword alerts. But as your marketing grows, its limitations become deal-breakers.
F5Bot sends you an email with a link when your keyword appears. That is the entire product. No dashboard, no history, no analytics — just a stream of emails you have to act on manually.
After receiving an alert, you need to open the thread, read the conversation context, write a relevant reply, and post it yourself. F5Bot does not help with any of these steps.
F5Bot restricts the number of keywords you can track on its free plan. If your product serves multiple use cases or you track competitor names, you quickly hit the ceiling.
F5Bot monitors Reddit and Hacker News only. If your audience also discusses your product category on Twitter/X, you need a completely separate monitoring solution.

Think of Replymer as F5Bot plus everything else you need to turn Reddit mentions into paying customers.
Every mention comes with an AI-generated reply that reads the full conversation and naturally recommends your product. No more staring at a blank text box trying to write something non-spammy.
Review the AI reply, edit if you want, and publish directly from the Replymer dashboard. No context-switching between email, browser tabs, and Reddit windows.
See all your mentions, generated replies, published posts, and performance metrics in one place. F5Bot gives you an email inbox — Replymer gives you a marketing command center.
Keep F5Bot running if you like, or replace it entirely. Either way, setup takes under 5 minutes.
No credit card required. Full access to every feature during the trial.
Enter the same keywords you use in F5Bot. Replymer starts scanning Reddit and Twitter/X immediately.
Give Replymer a short description of what you offer so the AI generates relevant, on-brand replies.
Mentions appear in your dashboard with AI-generated replies ready to go. Edit if needed, publish with one click.
F5Bot tells you about mentions. Replymer turns them into customers with AI replies and one-click publishing.
