jack friks@jackfriksYouTube is search, social proof, and community at the same time. Videos and comments keep ranking for months, so one unanswered question or complaint can shape future buyers long after it was posted.
Find comments asking whether your product is worth trying.
Catch creator mentions before the traffic spike disappears.
Answer objections under reviews, comparisons, and tutorials.
Collect customer language from long-lived comment threads.
Every platform has its own rhythm. Stalkr keeps social listening simple, then adapts the context, metrics, and priority signals to YouTube.
Monitor brand names, product names, competitor names, and category phrases across YouTube conversations.
See where the mention happened so you can understand whether it came from a review, tutorial, comparison, or customer thread.
See the exact likes, comments, views, title, description, and comment context returned by YouTube.
Find the comments where a helpful answer can convert a viewer, fix confusion, or correct outdated information.
Get notified when a YouTube mention needs attention without manually checking channels and comment sections.
Save useful source, keyword, date, and engagement views, then mark mentions for follow-up.
Start with Stalkr review, your product name, a competitor, or the exact phrase buyers use on YouTube.
Stalkr watches video comments and creator discussions where buying questions keep showing up long after publishing.
Matched comments and creator mentions stay beside their exact YouTube views, likes, and comment counts.
Open the original conversation, reply with context, save the insight, or turn it into product, support, or marketing work.
Connect Stalkr to ChatGPT, Claude, Codex, or any MCP client. New YouTube mentions flow straight to your agent, so it can filter the noise and bring you in only when something matters.

One day, a founder tweeted me asking if they could sell their startup on TrustMRR. I turned that single message into its acquisition marketplace. Founders started getting acquired, and the feature has since generated more than $150,000 in revenue.
More than 380,000 people follow what I build on X, so feedback comes in every day.
I use Stalkr to:

Stalkr tracks public mentions across X, Reddit, and YouTube for the keywords you choose: your product, brand, competitors, founder name, feature names, or niche phrases your customers use.
No. Stalkr is built for keyword monitoring, so it can catch public conversations where someone mentions your product or category without tagging you.
Yes. You decide the categories that matter to your workflow. Where platform policy allows, Stalkr uses AI to file mentions into those categories. YouTube API mentions remain exact and are not assigned derived categories or sentiment.
A mention is a public post, reply, thread, or comment that matches one of your tracked keywords or aliases. Stalkr dedupes and organizes them so you are not reviewing the same signal twice.
You can get email alerts for mentions you cannot afford to miss, like urgent complaints, bug reports, false claims, high-intent buying threads, or creator shout-outs.
Yes. Signed webhooks can send a mention.created event as soon as Stalkr finds a match. Your agent can then read the mention, source, context, engagement, and status through MCP or the API.
Yes. Stalkr exposes its supported workflows through a versioned REST API and an authenticated MCP server, so agents can manage projects, keywords, mentions, alerts, categories, saved views, and webhooks with the same permissions and limits as the dashboard.
No. The dashboard works normally, and OAuth-enabled MCP clients such as ChatGPT can connect without pasting an API key. Developers can also use scoped API keys, OpenAPI, and signed webhooks for custom systems.
