## The tools, ranked

### 1. ReplyGuy

- **Best for:** Marketers posting replies at volume on Reddit and X
- **Starts at:** $39/mo
- **Website:** https://replyguy.com

Finds mentions on Reddit and X, then writes the reply for you.

| Plan | Price | What it includes |
| --- | --- | --- |
| Basic | $39/mo | $199 a year. Entry tier. |
| Pro | $49/mo | 100 replies a month. $349 a year. |
| Business | $99/mo | 300 replies a month. $699 a year. |
| Scale | $199/mo | 1,000 replies a month. $1,399 a year. |
| Enterprise | $499/mo | 5,000 replies a month. $3,499 a year. |

**What's good**

- Relevance scoring and sentiment on every tier, not just the expensive ones
- Covers X alongside Reddit, which most Reddit-only tools do not
- Yearly billing takes five months off the price

**Where it falls short**

- Every tier meters replies, so the cost tracks your volume
- Entry is $39 a month, no longer the cheap way in it used to be
- No Slack, webhook or API on the public tiers

### 2. RedShip

- **Best for:** Founders who want customers from Reddit threads
- **Starts at:** $29/mo
- **Website:** /

Finds the Reddit threads where someone is about to buy, and drafts your reply.

| Plan | Price | What it includes |
| --- | --- | --- |
| 7-Day Pass | $12 one-time | Founder features for a week. No subscription. |
| Founder | $29/mo | 1 website, 10 keywords, 3 competitors, 1 seat. $290 a year. |
| Company | $49/mo | 3 websites, 30 keywords, 10 competitors, 3 seats. $490 a year. |

**What's good**

- Every post scored 0 to 100, so you skip the noise and engage where it counts
- Unlimited reply drafts written in your voice, with no monthly cap
- Surfaces Reddit threads already ranking on Google, so one comment keeps working

**Where it falls short**

- Reddit only. For X or LinkedIn monitoring, look at OctoLens or KWatch
- Not an audience research tool, so no subreddit discovery or pain-point mining
- Never posts for you, which is safer but means you do the last step yourself

### 3. KWatch.io

- **Best for:** Small teams who want cheap alerts on several platforms
- **Starts at:** Free
- **Website:** https://kwatch.io

Budget keyword monitoring across six platforms, with a real free tier.

| Plan | Price | What it includes |
| --- | --- | --- |
| Free | Free | 2 Reddit and 2 Hacker News keywords. No card. |
| Essential | $19/mo | 20 Reddit keywords. Sentiment analysis. |
| Business | $79/mo | Slack, API, webhooks and team management. |
| Enterprise | $199/mo | Highest keyword caps. |

**What's good**

- A free tier that needs no card, covering Reddit and Hacker News
- Six platforms including LinkedIn and Facebook for $19 a month
- Slack, API, webhooks and team management all land on the same $79 tier

**Where it falls short**

- The free tier skips every social platform
- 20 Reddit keywords on Essential runs out if you track competitors too
- No reply drafts on any tier

### 4. OctoLens

- **Best for:** Developer-tool teams watching many communities
- **Starts at:** $159/mo
- **Website:** https://octolens.com

Multi-platform social listening built for B2B and developer communities.

| Plan | Price | What it includes |
| --- | --- | --- |
| Pro | $159/mo | Billed annually. 15,000 mentions, 10 keywords, hourly refresh. Free trial. |
| Scale | $499/mo | Billed annually. 50,000 mentions, 40 keywords, real-time refresh, adds podcasts, news and newsletters. |
| Flex overage | Custom | Mentions beyond quota bill from $0.01 each, with a spend cap. |

**What's good**

- 13+ platforms including GitHub, Stack Overflow and Dev.to, unmatched for B2B developer tools
- API, webhooks and an MCP server on every tier
- Unlimited team seats at every tier

**Where it falls short**

- $159 a month to start is steep if you only care about Reddit
- Pro only refreshes hourly, so real-time means paying $499
- No reply drafts. It finds the conversation, you do the writing

### 5. Syften

- **Best for:** Developer-tool teams who need precise filter rules
- **Starts at:** $29.95/mo
- **Website:** https://syften.com

Boolean keyword filters across 15+ niche communities, delivered in under a minute.

| Standard | $49.95/mo | Adds AI filtering, API access and Slack. One month of archive. |
| PRO | $119.95/mo | 100 filters, webhooks and unlimited archive. |

**What's good**

- Boolean filter syntax, far more precise than plain keyword matching
- Covers 15+ niche communities that broader tools miss entirely
- 14-day trial with no card, and you see the last 60 days of mentions immediately

**Where it falls short**

- The entry plan allows 3 filters, which is restrictive if you track many terms
- Slack needs the $49.95 tier and webhooks the $119.95 one
- No reply drafts and no LinkedIn coverage

### 6. Popsy

- **Best for:** Bootstrapped founders who want simple AI lead discovery on Reddit
- **Starts at:** $19/mo
- **Website:** https://popsyai.com

AI reads each Reddit post and the person behind it to surface leads.

| Plan | Price | What it includes |
| --- | --- | --- |
| Free trial | Free | First 3 days free, no card needed. |
| Starter | $19/mo | Up to 100 leads a day. |
| Pro | $49/mo | Unlimited leads. |

**What's good**

- You control the search prompt yourself, which most tools hide
- Unlimited leads at $49, with no per-reply metering
- Three days free with no card before you decide

**Where it falls short**

- No Slack, webhook or API
- No team seats
- The company moved domains from popsy.ai to popsyai.com, so check your bookmarks

### 7. F5Bot

- **Best for:** Solo founders watching a brand name for free
- **Starts at:** Free
- **Website:** https://f5bot.com

Keyword alerts for Reddit, Hacker News and Lobsters, running since 2017.

| Platinum | $214.99/mo | 300 keywords, API and webhooks. $2,364 a year. |
| Diamond | $500/mo | Custom limits. Starting price. |

**What's good**

- The free tier needs no card and has run without interruption since 2017
- Silver at $9.99 removes the ads and adds keyword filtering, which is the real jump
- Covers Hacker News and Lobsters alongside Reddit

**Where it falls short**

- The free tier is 5 keywords with 10 alerts a day, so it runs out fast
- No reply drafts or engagement features on any tier
- Slack starts at $49.99 and the API at $214.99, which is steep for one channel
