As answered by people managing ChimpanSEO.app and https://open-gpt.app/.
ChimpanSEO.app's answer
ChimpanSEO is built for Generative Engine Optimization (GEO), not just classic SEO. Every article is engineered for AI citation: self-contained answer capsules under each heading, verifiable claims with sources, FAQ blocks, schema markup and high entity density. A built-in GEO Score (0-100) measures each article against 8 citation factors before you publish. Then one click publishes to WordPress with SEO meta for Yoast, Rank Math, SEOPress and AIOSEO.
ChimpanSEO.app's answer
Most AI writing tools optimize content to rank in Google's blue links. ChimpanSEO optimizes for where answers increasingly come from: ChatGPT, Perplexity and Google AI Overviews. If your content can't be extracted and cited by an AI engine, it's invisible to a growing share of searches. We also practice what we sell: our own blog is written and published with ChimpanSEO, and we document the results publicly rankings, citations and failures included.
ChimpanSEO.app's answer
SEO professionals, content marketers, agencies and small businesses that publish on WordPress and want visibility inside AI-generated answers. The product is available in English and Italian.
ChimpanSEO.app's answer
ChimpanSEO started in Italy in 2026 as an internal tool for publishing optimized articles to client WordPress sites. While using it, we noticed search behavior shifting from blue links to AI answers and that almost no tool was engineering content for AI citation. We rebuilt it as a SaaS focused on GEO and launched a public experiment: 28 articles in 30 days, generated entirely by the tool, with every result documented on our blog.
ChimpanSEO.app's answer
Next.js 16 (React 19, TypeScript) on Vercel, Supabase (PostgreSQL), Anthropic Claude and DeepSeek models via the Vercel AI SDK, Stripe for billing, and the WordPress REST API for publishing.
ChimpanSEO.app's answer
We launched in mid-2026, so we're early: our first users are small businesses and agencies in Italy. Rather than name-dropping, we publish our own results in public the ChimpanSEO blog is run entirely with the product, and the numbers (rankings, AI citations, misses) are documented openly.
