The problem

While you're reading this,

3 prospects just asked "which tool do you use for [your product]".

4 hours/day scrolling

Reddit, Quora, YouTube, LinkedIn... You know the mentions are there. But between checking by hand, stopping on the right posts and remembering to come back, your day is gone.

Replies that sound fake

You spend 20 min writing a "natural" reply so it doesn't sound promotional. Re-read it 4 times. Put your phone down. Come back. Hesitate. Close the tab. The post is now 3 hours old with 12 new replies.

Zero ROI tracking

You don't know if your reply got upvoted, if anyone clicked, if you got DMs. You redo the work every week flying blind. No data = no learning.

The solution

3 steps. Zero friction.

Describe your product once. KeyComment does the rest, continuously.

Questions

The real questions we get asked.

Isn't this just spam?+

No — and that's why we spent 2 years on it. KeyComment never posts automatically. You approve every reply, the AI drafts it in the post's context, actually answering the question. Copy-paste replies get spotted by communities (and by our filters). We aim for value, not empty volume.

Where does my data go?+

Self-hosted: nowhere. Your SQLite DB lives with you, we have no telemetry. Export in 1 click as SQL/JSON.

Which platforms exactly?+

Reddit (the pillar), YouTube (comments), Quora, LinkedIn, Twitter/X, Facebook (public groups), Instagram, Pinterest, TikTok, Threads. Plus Google/Bing/DuckDuckGo for discovery to catch forums and blogs off-platform.

How long does setup take?+

5 minutes: download the app, launch it, create your first domain, define 5 keywords. All 10 platforms are scanned within the first hour.

Which LLM is used?+

Your choice: OpenAI, Anthropic Claude, OpenRouter (200+ models), or your local LLM (Ollama, LM Studio). You bring your own key. You can also wire in a free local LLM and pay zero consumption.

Can I cancel anytime?+

Yes, anytime and unconditionally. The subscription has no commitment: cancel in 1 click from your account and keep access until the end of the period you already paid for. The only extra costs are your own LLM keys if you choose to use them (or a free local LLM like Ollama, $0).

Are updates included?+

Yes, automatically. As long as your subscription is active, you get every new feature, fix and platform — at no extra cost. Install KeyComment on all your computers.

What if I'm not satisfied?+

30-day full refund, no questions asked. Send an email, I refund you, we stay on good terms.

How does team mode work?+

You get a Pro or Business plan, then from your account you invite teammates by email. Each gets a link to set their own password and shares the same license as you — no extra purchase. You see seats used in real time and can remove a member (their access is cut instantly).

Can I manage my license and invoices myself?+

Yes, everything is self-service from your account: find your key, change your password, manage your team, see connected devices, download Stripe invoices, request a refund (≤ 30 days) and export all your data (GDPR) in one click. No need to email us.

Is there a free version?+

Yes, free forever: 1 domain, 3 platforms, 1 scan per day, no credit card. Upgrade the day you want more domains, all platforms, or continuous monitoring.
