**Short answer:** they solve different problems. Proofsource is a subscription platform (with a free plan) that tracks how AI answers about your brand change over time. Preferly is a one-time $99 audit that asks 10 AI models once, checks every claim they make about you against your website, and gives you paste-ready fixes. Pick Proofsource if you want ongoing tracking, or Google AI Overviews and Perplexity today. Pick Preferly if you want one clear report and a fix list without a subscription.

## Questions

### Is Proofsource cheaper than Preferly?

It can be. Proofsource has a free-forever plan and a Starter plan from $9 a month. Preferly is $99 once with no subscription. Over a year, Starter costs about the same as one Preferly report, so pick on what you need, not on price alone.

### Does Preferly check Google AI Overviews or Perplexity?

Not yet. Preferly asks 10 AI models through their APIs. Proofsource's free first scan and paid plans include Google AI Overviews and Perplexity.

### Can I use both?

Yes. Some owners run a one-time Preferly report to find what to fix, then use a tracker to watch the numbers afterwards.
