Honestly the biggest unlock was cutting scope. I spent a year adding features nobody asked for before I figured that out.

Worked great the first month, then it slowly stopped holding a charge. Wish someone had warned me before I bought.

I almost quit before a comment here told me to niche down. That one change is what finally made it click.

Finally a video that doesn't skip the boring middle. The part around 8:40 on retention was gold.

Summary

Entrepreneurs in this community are deeply concerned about validating their ideas and finding paying customers. They feel a mix of excitement and anxiety, often isolated and overwhelmed by the challenges of building a startup. There's a strong desire for practical advice on launching quickly, iterating on feedback, and overcoming self-doubt.

Free and transparent, not freemium

Free and source-available. The others are neither.

The closest extensions give you Reddit free, then charge to unlock YouTube, Amazon, and the rest. The hosted tools want a monthly subscription. CommentGrab is free on all 13 platforms, source-available so anyone can audit it, and it runs on your machine.

Most comment exporters
  • Closed source. You can't see what they do with your data.
  • Sign up for an account before you can export.
  • Free to start, then paid or credit-gated for real use.
  • Your comments run through their servers.
  • Built for social exports and giveaways, not research.
  • AI insight is an upsell, if it exists at all.
CommentGrab
  • Source-available. Audit every line on GitHub before you trust it.
  • No account. Install it and go.
  • Free on all 13 platforms. No trial, no upsell, no per-export fee.
  • Runs in your browser. Nothing is uploaded.
  • 13 research sources, one widget.
  • BYO OpenAI key for objections, hooks, and exact wording.

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.
Ad angle
Lead with the free tier: "the $45/mo tool, but free and source-available." Their words, aimed back at them.
Feature request
Several people asked for LinkedIn and TikTok. That's your roadmap.
