At Rewardful, we're huge believers in word-of-mouth marketing. I've used most of the social monitoring tools on the market and most have a lot of noise in the results or miss important conversations happening online. Syften returns the most relevant social mentions with the least amount of noise out of all the tools I've tested so far. Their community listening is the best on the market and I love how you can fine tune by source.
I love that Syften monitors all the communities I am part of but don't have enough time to check all day. Now, I can check my email and see conversations happening on Twitter, Reddit, Indie Hackers, and many more places. It's incredibly useful. Worth every dollar.
We use Syften to react to people saying things about us on the internet every single day. It's a set once and forget tool that just helps your team keep your pulse on whatever it is you care about.
Syften is awesome. I use it for my business so I can monitor the brand, and participate in online discussions which can help us attract new customers. I also use it personally to keep track of niche subjects that I'm interested in like emerging tech and products.
We love Syften at PostHog and find it incredibly useful for listening to our open-source community. The Slack integration enables our entire team to find ways to connect with our users, whether it's the Marketing team sharing new content or the Engineering team answering technical questions. The filtering system is especially powerful and helps us separate the signal from the noise.
I've written a couple books and like to keep an eye on how and where folks are talking about them. Syften has helped me catch several key conversations that I otherwise wouldn't have seen. Even on the days without any notable alerts, I'm still happy to know that I haven't missed anything. A very useful tool.
Syften has become integral to our business. It allows us to monitor *and* respond in real-time using their super simple webhooks. For example, when people mention our competitors being expensive on Twitter, Syften finds it and enables us to respond instantly with Zapier. It's paid for itself many times over. It even helped us secure $5M in funding for one of our community members. Michael has been overwhelmingly supportive over the past 18+ months we've been a customer and we couldn't be more grateful.
I use Syften every day and have been for a year. I looked at various other social listening tools but they were mostly aimed at big brands and enterprise customers and carried a hefty price tag. Syften tracks all of the major networks that I'm interested (even ones the big tools don't) and it's affordable for businesses of every size. Every day I get an email digest of people talking about my product for me to take immediate action on.
I gather the mentions I get from Syften and add them to our customer sales and partner presentations to show how our product is gaining mindshare amongst users on Reddit and forums. These slides are very impactful.
Syften has been a great tool to understand in which communities my website is being mentioned, or topics relevant to my business. It allowed me to engage in meaningful discussions and to identify some important actors in my niche.
Syften has enabled us to keep an eye on the topics related to our product. We can easily track posts about discount codes, email marketing, and e-commerce. We can then suggest using our service, or just be helpful answering questions on subjects that we are familiar with.

Frequently asked questions
What is Syften?
Syften is an AI-filtered keyword monitoring tool for Reddit, X/Twitter, Hacker News, forums, blogs, GitHub, YouTube, Slack communities, Bluesky, Mastodon, and other online communities.
It helps founders, marketers, and support teams find brand mentions, competitor mentions, problem phrases, and buying-intent conversations as they happen.
Is Syften a Reddit keyword monitoring tool?
Yes. Syften is a Reddit keyword monitoring tool that tracks Reddit posts and comments for chosen keywords, brand names, competitors, and problem phrases.
Reddit alerts can be delivered through email, Slack, RSS, API, or webhook, with a target Reddit delay of under 1 minute.
Do you really track Reddit live?
Yes, we aim for at most a 1-minute delay. For live Reddit monitoring, Syften specializes in live content delivery instead of historical search, so it can run precise keyword filters and CPU-heavy matching logic that general search alerts usually cannot support.
How is Syften different from Google Alerts?
Syften is better suited than Google Alerts for live Reddit monitoring, forum monitoring, and community monitoring because it tracks discussion sources directly, sends near-real-time alerts, and supports precise keyword filters.
Google Alerts can still be useful for broad web mentions because it uses Google's web index, but it is not designed for complete Reddit or forum monitoring. Because it is free, there is no reason not to use Google Alerts alongside Syften.
How is Syften different from social listening tools?
Syften focuses on community keyword monitoring and high-signal alerts from sources like Reddit, Hacker News, GitHub, forums, blogs, YouTube, and Slack communities.
Traditional social listening tools often emphasize dashboards, brand analytics, and large social networks. Syften is built for finding conversations you can act on quickly.
Is Syften a GummySearch alternative?
Yes. If you came here because GummySearch is shutting down, Syften can help cover some of the same monitoring workflows.
GummySearch currently lists Syften as a recommended alternative for cross-platform brand monitoring because Syften tracks keywords on Reddit and 10+ other platforms.
How do you keep noise down while preserving signal?
AI filtering runs on top of your full mention stream and suppresses low-value traffic like spammy posts, repetitive posts, auto-promos, duplicates, and weak matches.
You keep control of your keyword filters, but your inbox stays focused on human conversations that are more likely to become sales, support, research, or marketing opportunities.
Can Syften monitor competitor mentions and buying-intent phrases?
Yes. Syften can monitor competitor names, product categories, pain points, problem phrases, comparison searches, and keywords that indicate buying intent.
This makes it useful for lead generation, customer research, competitor monitoring, founder-led sales, and finding relevant Reddit or forum discussions before they go stale.
Does Syften monitor LinkedIn?
No, unfortunately not.
Which communities does Syften monitor?
Syften monitors these communities:
Where can Syften send alerts?
Syften can send keyword alerts by email, Slack, RSS, API, and webhook. This lets teams route Reddit alerts, forum alerts, brand mentions, and competitor mentions into the workflow they already use.
Does Syften have an API?
Yes. Syften has an API for teams that want to pull keyword alerts, Reddit mentions, forum mentions, brand mentions, and competitor mentions into their own tools or reporting pipelines.
Does Syften have a Slack integration?
Yes. Syften has a Slack integration, so keyword alerts from Reddit, forums, blogs, GitHub, YouTube, and other monitored communities can be delivered directly to a Slack channel.
Does Syften have AI integration?
Yes. Syften can use AI to filter noisy keyword matches and keep your alerts focused on relevant conversations.
Syften can also review your monitoring configuration with AI, or pass results through the API so your team can run in-house AI filtering, scoring, enrichment, or routing.
Does Syften support webhooks?
Yes. Syften supports webhooks, so keyword alerts can be pushed to your own application, internal workflow, CRM, enrichment system, or automation stack as soon as matching conversations are found.
Who is Syften best for?
Syften is best for founders, marketers, indie hackers, support teams, and agencies that need to find relevant online conversations quickly.
Common use cases include Reddit monitoring, brand monitoring, competitor monitoring, lead generation, customer research, community monitoring, and support escalation.
