An AI content tool built exclusively for X (Twitter) growth. Bring an idea, and CreatorBuddy helps shape it into a post, scores its likely performance on 9 algorithm metrics before publishing, flags risks that could hurt account reach, and suggests improvements—so you can iterate on hooks and structure without burning your audience on a weak draft. Features include AI Content Coach (topic recommendations from your history), Algo Analyzer (pre-publish scoring with alternative versions), Content Composer (repurposing into threads/tweets), Reply Guy (fast replies to large accounts), Account Researcher (why others go viral), and a Chrome extension. Founded by Alex Finn (ex-MongoDB, built the app solo in ~3 months with Cursor); launched Jan 2025 and hit $100K ARR in 15 minutes, $300K ARR in two weeks, with ~500 paying subscribers. Pricing: $49/month or annual (saves $89), 7-day free trial. Note: X-only—no cross-platform publishing; no API and no self-hosted option; no permanent free tier (trial only); limited formal user reviews (ScamAdviser trust score 86/100, flagged legit; one independent 7-day experiment documented). Not to be confused with the separate “CreatorBuddy” creator campaign engine on Contra.
