As answered by people managing Nullstack and CouncilAds.
CouncilAds's answer:
CouncilAds tests your ad or landing page against twelve AI buyer personas, each built on an empathy map, instead of one generic "ideal customer." Each persona gives an intent score and says what would stop them from clicking, so you see objections from a skeptic, a price shopper, someone burned before, and someone ready to buy. You get the score, the objections ranked by how many of the twelve raised them, and three fixes in priority order. The Google Ads tool writes pain-led and outcome-led ads, has the Council pick a winner, and runs challenger rounds to beat it. The Landing Page Review also checks the page against your ad for message match. It is a first read before you spend on clicks. 6 free runs, no credit card required.
CouncilAds's answer:
Most ad tools write ads or report on clicks after you have already paid for them. CouncilAds tells you before you spend. Twelve AI buyer personas read your ad or landing page the way different real buyers would, and tell you who would click, what stops them, and what to fix first. Instead of one imagined customer, you hear from a skeptic, a price shopper, someone burned before, and someone ready to buy. It tests the whole path: the ad, the landing page, and whether the page continues what the ad promised. Fixes are specific and ranked, and you can apply them and re-score in the same tool. There is no sales call and no setup: 6 free runs, no credit card required, and your first run needs no signup. It is a first read before you spend, not a promise of results, so use it to catch the obvious leaks before real clicks cost you money.
CouncilAds's answer:
Small business owners and solo marketers who run their own Google Ads and cannot afford to waste budget on ads or landing pages that do not convert, plus freelancers and small agencies who manage ads for several clients. They are not paid-search specialists with a testing team. They want a quick, plain-language second opinion on an ad or page before they spend on clicks.
CouncilAds's answer:
CouncilAds started from a simple problem: small businesses pay for Google Ads clicks before they know whether the ad or the landing page will convince anyone. Hiring a marketer or running A/B tests costs money most owners do not have. So we built a Council of twelve AI buyer personas, each based on an empathy map, that reads your ad and page first and tells you what would stop a buyer from clicking. It is a first read before you spend, built for owners who want a straight answer instead of a sales pitch.
CouncilAds's answer:
CouncilAds is built with TypeScript and React on the front end, serverless functions hosted on Vercel, and Supabase for the database and accounts. The AI analysis runs on Anthropic's Claude models. Payments are handled by Stripe and transactional email by Resend.
