Lettertrace finished #2 on Product Hunt August 12 with 233 upvotes on a one-line proposition: track your brand's visibility inside AI answers for free, using your own API keys. The AI-visibility / generative-engine-optimization tooling category has been selling exactly this as a paid analytics subscription, with the vendor's inference cost baked into the seat price. Pushing that cost back to the customer's own key lets the product be free at zero marginal cost to the vendor — the clearest example this week of BYOK being used as a pricing weapon rather than a compliance feature.
