Free and open, not freemium

Every other exporter wants $45 a month

Most comment exporters are closed, single-platform, and gated behind credits. CommentGrab is the opposite, on purpose.

Most comment exporters

Freemium. A handful of exports, then a paywall.
$45 a month for the tier that actually works.
Make an account before you can do anything.
Your comments run through their server.
One platform per tool.
Closed source. You can't see what it does with your data.

CommentGrab

Free. No export limit, no trial, no upsell.
$0. You only pay your own OpenAI usage, and only if you use AI.
No account. Install it and go.
Runs in your browser. Nothing is uploaded.
Nine sources, one widget.
Open source (MIT). Read every line on GitHub.

Honestly the free tier is all I need. The paid plan feels aimed at agencies, not solo builders.

Switched from the $45/mo tool. This does 90% of it for free and the export is cleaner.

What the replies are really saying

Your OpenAI key

CommentGrab samples the most relevant comments and returns structured, copyable insight.

Top objection

People aren't saying it's too expensive. The paid plan feels built for agencies, not solo builders.

Winning hook

People keep citing the free tier as the reason they switched. Lead with it.

Verbatim language

"does 90% of it for free." "the export is cleaner." Copy these straight onto your landing page.

Feature request

Several people asked for LinkedIn and TikTok. That's your roadmap.
