Cali is an AI calorie tracker and weight-loss coach that works inside ChatGPT and Claude. Just say what you ate — or snap a photo — and Cali logs it, estimates the calories, tracks your daily total, weight trend and streak, and coaches you. No separate app to download: it runs as an MCP connector in Claude (or an app in ChatGPT), works on web, phone and desktop, learns your regulars so logging gets faster, and is judgement-free. Free 3-day trial.

AI-integrated tools for learning, writing, and publishing. ProvenanceAI builds free MCP tools that help authors develop and protect their voice, editors assess manuscript quality, instructors design humanities courses, and researchers produce defensible, well-sourced work. Current tools cover editorial analysis: voice profiling, authenticity scoring, structural review, style consistency, research grading, and manuscript readiness. Expanding into curriculum design, academic writing, and book production workflows. No email gate. Every tool returns a full structured result on the first call. Powered by ProvenanceAI × Exact Rush.

cityparity gives AI agents real cost-of-living and quality-of-life comparison tools. Point it at two cities and it returns take-home pay, a full cost breakdown (housing, healthcare, childcare, food, transit, travel home, property tax), and the equivalent salary you'd need in the target city to come out even. It also surfaces the non-cash deltas people actually move for: vacation days, parental leave, universal healthcare. Beyond two-city compares, it ranks cities by a composite quality score and looks up inbound-worker tax regimes (Italy impatriati, Portugal IFICI, and a few others). Over 165 cities across 69 countries. Free, no API key, hosted Streamable HTTP.
