Disclosure first: I make Loudship. The facts about Syften on this page come from syften.com and its pricing section, checked on October 31, 2026. Quotes are its own words.
What Syften is built for
Syften has been "operating since 2019", and it does one job at a very high standard: it watches a long list of online communities for the search queries you give it, and delivers every match almost as soon as it is posted. The list runs from Reddit, Hacker News, Bluesky and Mastodon to Indie Hackers, Stack Overflow and the rest of Stack Exchange, GitHub, Discourse forums, Slack communities, Lobsters, DEV, podcasts, newsletters and the open web. X and YouTube are paid add-ons. On Reddit it aims for "at most a 1-minute delay", and a match can go to email, Slack, RSS, its API or a webhook.
A Syften filter is, in its words, "a search query for mentions you want to track", written in what it calls its "powerful syntax": you decide exactly which phrasings count and which do not. Syften says it helps "founders, marketers, and support teams find brand mentions, competitor mentions, problem phrases, and buying-intent conversations as they appear". From the Standard plan up, an AI layer "runs on top of your full mention stream" and suppresses spammy posts, repetitive posts, auto-promos, duplicates and weak matches. What reaches you is everything your filters caught that survived that pass, in real time.
A live feed and a morning shortlist
The two tools run on different clocks. Syften is a feed: a match lands in your inbox or a Slack channel within a minute, and the feed keeps running all day. Loudship is a shortlist: it goes through Reddit, Hacker News and Bluesky overnight, keeps only the threads written by someone in a buying moment, and sends them in one email in the morning.
A minute matters when the post is about you. A customer reporting a bug, a launch thread filling up, a complaint that needs an answer before it gathers agreement: for those, a live feed is the right tool and a morning email is the wrong one. A minute matters much less for the other kind of thread, a stranger asking which tool fixes something that bothers them. Those questions keep collecting answers long after the first hour, and the reply that helps is the one that answers the question well. Loudship is built for that second kind of thread, and only for it.

What $29.95 a month covers on Syften
Syften's Entry plan, at $29.95 a month, is the one closest to a solo budget, and Syften describes it plainly: "Keep an eye out for your product name". It includes three community filters and one web filter, up to 100 community results a day and seven days of archive search, without the AI filter. For a product name, three filters are plenty.
Looking for buyers takes more queries. A founder usually wants one filter per competitor ("X alternative", "switching from X"), a few for the problem in the words people type ("track billable hours across clients"), and one for the category. That is past three filters on the first day, and without the AI filter every loose match of a category word reaches you. The plan built for that work is Standard, $49.95 a month: 20 community filters, 200 results a day, 30 days of archive, Slack, and AI filtering. PRO, $119.95 a month, raises the count to 100 filters and adds webhooks, an MCP server and the full archive. X monitoring costs $40 a month on top, YouTube $20. The pricing page shows monthly prices only, and the 14-day trial runs on PRO, without a card.
On Loudship, one product costs $29 a month on Solo, and you do not start from an empty filter box. Loudship reads your website and proposes the topics people use for your category, three to five competitors your buyers might leave, and a few questions phrased the way someone asking for help types them. You correct the list, and the radar searches from it every night.
From a match to a decision
A match says the words were there. Three questions are still open before you reply: is the author actually looking for a tool, does your product do what they ask, and what do you say? Loudship settles the first two before the email goes out, and drafts the third.
Every thread is first sorted by intent. Three kinds reach the digest: an explicit need ("looking for a tool that…"), a search for an alternative to something the author uses today, and a frustration with their current tool. General discussions of the topic, and news about a competitor with nobody looking to switch, stay in the web app, out of your morning.
Then comes the fit card. Loudship lists what the author asks for, criterion by criterion, and marks each one against your product memory: yes, no, or unknown when the memory says nothing about it. Say you sell a time tracker and someone writes: "Need a time tracker for a four-person agency. Must export to Xero, ideally under $10 a seat." The card reads: four-person team, yes; under $10 a seat, yes; Xero export, unknown. The verdict is "Check the fit", and the draft states only the first two. Whether you support Xero is yours to confirm before posting; the draft does not guess.
That card is the part a keyword stream cannot give you, however good its filters are, because it needs to know your product. Syften knows your queries. Loudship knows what you sell, what it cannot do, and the claims you never want made about it.
When Syften is the better pick
- Minutes count. Support, outages, launches, anything with your product's name in it. Syften's one-minute target on Reddit is what you want there.
- Your buyers live outside Reddit, Hacker News and Bluesky. Developers on Stack Overflow and GitHub, a community on Discourse or Slack, a niche podcast: Syften covers those places, Loudship skips them.
- You want the raw stream in your own tools. RSS feeds, the API, webhooks and MCP let you route every match to a CRM, a spreadsheet or your own AI agent. Syften's line on it is "We provide the mentions and get out of the way."
- You want exact control. If you know precisely which phrases matter and want every hit, a filter syntax beats a scored shortlist.
- Requests hide in comments. Syften tracks Reddit posts and comments. Loudship searches posts.
Moving your Syften filters into Loudship
The filters you already wrote are the best starting point you have: they hold what you learned about how your buyers talk. They map onto Loudship like this.
- Your product name stays on an alert. Loudship looks for people who do not know you yet; it does not monitor your brand. Keep Syften Entry or a free keyword alert on your name, as described in the F5Bot comparison.
- Competitor filters become competitors. Add each one to your product memory. Loudship turns every competitor into a search for "X alternative" on Reddit and Bluesky, and for the name itself on Hacker News, then scores what comes back for someone on the way out.
- Problem phrases become topics or questions. Short phrases, one to three words, go in as topics. Longer ones, written the way a person asks for help, go in as Reddit questions, which run ahead of the topic searches.
- Exclusions become skip reasons. Instead of excluding a word, skip the thread and say why. Fewer threads of that kind come back.
What you will not get back is the speed, or the communities beyond those three. If either is the reason you chose Syften, keep it. If the reason was finding buyers, a week of both will tell you more than this page: Syften's trial and Loudship's first digest both start without a card. Either way, the reply decides whether the account survives; here is what a reply that survives looks like.
