Generic news apps are broad, but they are weak when you need to follow one niche topic closely
Manual searching works for a while, then turns into dozens of tabs, newsletters, alerts, and bookmarks
Most feeds show too much noise and not enough context on what changed and why it matters
Knock gives you a topic tracking app that can monitor specific interests, summarize important updates, and let you spend more time acting on insights instead of collecting them.
Create focused monitoring for anything from AI agents to startup funding, medical research, or competitor launches.
Use concise updates to decide what deserves attention before opening the full source.
Keep work, research, and personal interests organized instead of mixing everything into one noisy feed.
Use daily briefs and deeper analysis for the topics where a quick update is not enough.
Simple setup. Powerful results.
Add the exact topics, companies, or niches you want to monitor instead of settling for a generic category.
Knock keeps watch on your selected topics and surfaces the updates worth reading.
Read the short update, request a daily brief, or go deeper when the story affects your work.
If a topic tracker only gives you a list of links, it still leaves the hard work to you. The better workflow is to surface the change, summarize it, and make the next step obvious.
Sample brief structure
The conversion goal on these pages should be simple: help someone understand the value fast, try it with free credits, and upgrade only when the workflow saves them real time.
The free credits are enough to test whether topic tracking fits your workflow before you spend anything
Paid usage is simple: 1 credit for an update, 2 for a daily brief, and 3 for deeper analysis
This works well for people who need multiple topic streams without paying for a bloated subscription they may not use every month
The value case is straightforward: if focused monitoring saves time every week, buying more credits is easier than maintaining a manual research habit
A normal feed pushes broad categories to everyone. A topic tracking app is better when you want to define the exact topic, company, industry, or niche you want to monitor and then summarize only the updates relevant to that scope.
Yes. The main use case is tracking narrower topics that generic feeds and newsletters usually miss or cover badly.
Usually after they test a few real topics, see the time saved, and want more updates, daily briefs, or deeper analysis. The product converts best when the page shows a clear workflow and a clear reason to keep using it.
