Verdict
A focused tracker with a useful free audit. Treat share-of-voice as a trend, not the truth. Free to $599 a month is steep for a small business.

Founders who want a baseline of how AI assistants describe their brand.
Watch out
Paying $599/month before the free audit has shown you fixes you can actually ship.
Stay in command
Three moves for this week.
-
Accuracy
Read answer-share scores as a trend, not a verdict: re-run your top buyer prompts in ChatGPT and Perplexity yourself before rewriting pages to chase a number.
-
Privacy
ReSO's terms say the brand data you submit stays your property and is licensed only to run the service; still sign up with a work alias and share only public brand details.
-
Cost
Start with the free one-off audit (baseline, AISO report, six technical fixes, one blog). The $599/month plan is paid upfront monthly and cancellable, so ship the free fixes first.
Watch out: optimizing for a visibility score instead of for the buyers asking the questions.
Power and Risk scores are editorial judgment for marketers and small-business operators, not laboratory tests or legal advice. Power = leverage (dangerous in a good way). Risk = what can go wrong (privacy, wrong answers, lock-in, cost surprises). Tools change; re-check pricing, privacy policies, and data controls before you adopt anything.
