ThreadScope vs F5Bot
F5Bot has been emailing keyword alerts since 2017, and it's earned its reputation. But an alert only tells you a word matched. ThreadScope reads the thread, weighs it against what you care about, and helps you reply well. Here's an honest look at which one fits your work.
F5Bot prices and limits verified against f5bot.com/tiers on 26 August 2026
F5Bot: a keyword net
F5Bot watches every post and comment on Reddit, Hacker News and Lobsters for the keywords you set, and emails you when one appears. It's simple, reliable, and the free plan is a genuine free plan. What it doesn't do is tell you whether the match matters: there's no dashboard, no triage, and no sense of what the thread is actually about.
ThreadScope: a triage desk
ThreadScope watches the subreddits where your people are. Every new thread lands in one queue, tagged by keyword or semantic match, with AI analysis on every plan. You clear the queue like email, and when a thread deserves a reply, Scope drafts one with the full context - or tells you to stay out of it.
The head-to-head
| Feature | F5Bot | ThreadScope |
|---|---|---|
| Coverage model | Keywords across all of Reddit, Hacker News and Lobsters | The subreddits you choose (3 free, up to unlimited) |
| Free plan | 5 keywords, 20 alerts/day, delivery within 2 hours | 3 subreddits, ~25 built-in AI post analyses/month |
| First paid tier | $9.99/mo (20 keywords, faster email) | $5/mo Scout (5 subreddits, ~120 AI analyses) |
| Matching | Literal keyword matching, with filter flags | Keyword tags on every plan; semantic matching from Patrol ($15/mo) |
| AI | AI filtering from Gold ($49.99/mo), metered as a $10 token allowance | AI post analysis on every plan, including free |
| Where results land | Your email inbox (RSS/JSON from Gold) | A triage dashboard with statuses, tags and keyboard shortcuts, plus email digests |
| Reply help | None - alerts link to the post | Scope drafts a reply with context, and says so when a post isn't your moment |
| AI agent access | RSS/JSON on Gold ($49.99/mo) | MCP server on every plan; full access from Patrol ($15/mo) |
ThreadScope's full ladder is on the pricing page. AI analysis estimates are fair-use figures; see pricing for details.
F5Bot's current pricing
F5Bot repriced in 2026, and most reviews you'll find still describe the old plans (200 free keywords, "Power" and "Ultra" tiers). This is the ladder they publish now. Annual billing gives roughly one month free, and a custom Diamond tier starts at $500/mo.
| Plan | Price | Keywords | Daily alerts | Speed | Notable |
|---|---|---|---|---|---|
| Free | $0 | 5 keywords | 20 alerts/day (10 per keyword) | Within 2 hours | Personal use only; email with ads, basic filtering |
| Silver | $9.99/mo | 20 keywords | 100 alerts/day | Within 5 minutes | Full post text, ad-free, filtering flags |
| Gold | $49.99/mo | 200 keywords | 5,000 alerts/day | Instant or scheduled | AI filtering (first $10 of tokens included), RSS/JSON, 1 Slack/Discord |
| Platinum | $214.99/mo | 300 keywords | 200,000 alerts/day | Instant or scheduled | API and webhooks, 3 Slack/Discord integrations |
The comparison that matters: F5Bot's first tier with any AI is Gold at $49.99/mo, and its AI is a filter with a metered token allowance. ThreadScope's Patrol plan costs $15/mo and includes semantic matching plus ~450 full AI post analyses. Even Command, with unlimited subreddits and MCP API keys at $30/mo, costs 3/5ths of Gold.
Which one should you pick?
Choose F5Bot if…
- -You need to catch a brand name anywhere on Reddit, not just in communities you follow.
- -You also want Hacker News and Lobsters in the same alert stream.
- -You want email alerts and nothing else - no dashboard, no workflow.
- -Your keywords are rare enough that 20 alerts a day is plenty.
Choose ThreadScope if…
- -Your work happens in specific communities and you want every relevant thread there, not keyword hits everywhere.
- -You want to know whether a thread is worth replying to, not just that a word matched.
- -You triage as a workflow: statuses, tags, keyboard shortcuts, a queue you can actually clear.
- -You want AI that reads the whole thread and drafts a reply - included from the free plan, not a $49.99 add-on.
And genuinely: the two work well together. Keep F5Bot as a wide net for your brand name anywhere on Reddit, and use ThreadScope for the communities where you actually show up and reply.
Common questions
- Is F5Bot still free?
- Yes. F5Bot's free plan currently includes 5 keywords, up to 20 alerts a day, and delivery within about 2 hours, for personal use. Many older reviews still describe the previous free plan of 200 keywords; that no longer matches F5Bot's published tiers.
- Does ThreadScope monitor all of Reddit like F5Bot does?
- No, and that's deliberate. F5Bot matches keywords across every subreddit; ThreadScope watches the subreddits you choose and reads everything posted there. If you need a catch-all net for a rare brand name, F5Bot does that well. If you work in particular communities, subreddit-scoped monitoring catches relevant threads that never mention your keyword.
- What does ThreadScope's free plan include?
- The free Lookout plan watches up to 3 subreddits with keyword tag matching and includes roughly 25 built-in AI post analyses a month. No credit card required. See the pricing page for the full ladder.
- Can I use F5Bot and ThreadScope together?
- Yes, and it's a sensible combination: F5Bot as a wide keyword net for brand mentions anywhere, ThreadScope for the communities where you actually participate and reply.
- Does ThreadScope cover Hacker News?
- ThreadScope monitors Reddit. On paid plans, Scope's research tools can search Hacker News and the web while helping you write a reply, but Hacker News threads don't appear in your monitoring queue (yet).
- Does ThreadScope post to Reddit for me?
- No. ThreadScope drafts replies; you review and post them yourself. Automated posting is a fast way to get banned from communities, and drive-by promotion is exactly what ThreadScope is built to avoid.
