Syften Alternative
Syften starts at $29.95 a month and aims to flag a Reddit mention within a minute (as of Nov 3, 2026)1. Writing and posting the reply is still your job. SlopMog's $99 plan finds Reddit and YouTube threads every day, then drafts and posts about 166 comments a month.
- Pick SlopMog if…
- you'd rather not write the replies yourself: Reddit and YouTube threads found daily, a comment drafted for each, posted for you at $0.60 a comment.
- Pick Syften if…
- you write your own replies and want to hear about mentions within a minute, on Hacker News, Slack communities, forums and Stack Exchange too, from $29.95 a month.
- The math
- Syften Standard with YouTube is $69.95 a month for alerts, and every reply is yours1. SlopMog's $99 covers about 166 regular comments, written and posted. Running both is $168.95.
Syften figures from its pricing page and FAQ, checked Nov 3, 20261. SlopMog's $0.60 is 6 credits at $0.10 each.

Syften: the good and the meh
We could pretend they're terrible. They're not. Every point links to where we read it.
What Syften does well
- Reddit alerts with a target delay under 1 minute1
- Covers places most Reddit tools skip: Hacker News, Indie Hackers, Slack communities, Discourse forums, Stack Exchange, GitHub, podcasts and newsletters1
- Starts at $29.95 a month, with API access on every plan1
- Webhooks and MCP on PRO, so your own AI agent can work through the mentions1
- AI filtering on Standard and PRO to cut the noise around common-word brand names2
- A 14-day PRO trial with no card that shows the last 60 days of mentions straight away1
Where it falls short
- It doesn't write or post replies. Its own words: "We provide the mentions and get out of the way."1
- YouTube (+$20/mo) and X (+$40/mo) are add-ons, sold on Standard and PRO only2
- Entry has no Slack and no AI filtering. Both start on Standard at $49.951
- YouTube monitoring watches search results, at least once a day, and doesn't look inside the videos2
- No LinkedIn monitoring1
- No separate user seats: a team shares one login and routes alerts by email, Slack or webhook2
Why consider SlopMog instead
Besides the obviously superior name. Here's what changes once the alerts stop being a to-do list.
Somebody still has to write the reply
Syften's pricing page says it plainly: "We provide the mentions and get out of the way."1 Its own blog runs a case study called "A Comment Worth $140"3, and the comment is the part an alert can't write for you. SlopMog starts where the alert stops: it finds the thread, drafts the comment and posts it.
- Reddit and YouTube threads found every day
- A draft waiting for each one, in the thread's tone
- Posted on a staggered schedule, never in a burst
- Health checks show which comments are still live
Approve each draft, or not even that
Every opportunity arrives with a comment drafted in the thread's tone, in one of 5 voices or Auto. Edit it, regenerate it with another voice, approve it or skip it. Or switch a site to hands-free, and SlopMog posts within a daily budget per platform.
- 5 voices plus Auto
- Edit, regenerate or skip any draft
- Hands-free mode, per site
- Reddit comments posted from aged Reddit accounts
YouTube comments, not YouTube alerts
On Syften, YouTube is a $20-a-month add-on for Standard and PRO with 10 filters. It watches YouTube search results, checks at least once a day and, in its docs' words, does "not analyze the contents of the videos."2 SlopMog finds videos for your keywords alongside the Reddit threads, scores them, and posts a comment under the ones you approve.
- A YouTube comment costs the same 6 credits ($0.60) as a Reddit one
- No add-on to switch on
- Scored for relevance before they reach you
- High-Value YouTube threads too
The threads AI models cite when they search
Syften uses AI to filter your alerts. SlopMog's High-Value discovery points it the other way. It writes 40 buyer-style questions without your brand name, asks each one to Gemini, Claude, GPT and Grok with live web search, then checks and ranks every Reddit and YouTube thread they cite. It runs weekly, when you add a site, or on demand.
- 40 buyer questions by default, no brand names
- 4 AI models, each with live web search
- Cited threads checked and ranked
- A High-Value comment is 60 credits ($6)
Let's talk money
Syften charges for filters and results a day, SlopMog for comments. Build your Syften month, then decide who writes the replies.
Your month
- Results a day, up to
- 220
- Comments written and posted for you
- ≈ 166
Syften finds the conversations. SlopMog writes and posts about 166 comments a month on Reddit and YouTube, at $0.60 each in credits.
Monthly prices from Syften's pricing page1, add-on terms from its docs2. Syften offers annual billing but doesn't publish annual prices, and its Tailor made plan is priced on request. Some directories still list $19.95, $39.95, $99.955. We used Syften's own page. SlopMog comments are 6 credits ($0.60) each.

- You want your own AI agent on the mentions, through an API, webhooks or MCP

SlopMog might be better if…
- The alerts arrive fine, and the replies never get written
- You want a draft for every thread, approved by you or posted hands-free
- You want comments under YouTube videos, not only alerts about them
- You want to comment in the threads Gemini, Claude, GPT and Grok cite when they search
