A free macOS menubar app that captures a screenshot and asks GPT-4o to analyze or explain it. Useful for debugging code errors, generating code from Figma designs, getting UI/UX feedback, analyzing charts, or solving math equations (LaTeX rendering supported). Built by Daniel Nguyen (also of BoltAI) as a native macOS app for Intel and Apple Silicon. Free to download; requires your own OpenAI API key (BYOK), with costs based on OpenAI usage. API key stored in Apple Keychain; developer does not store or analyze your content. macOS 12+ only.

A desktop email marketing app for Mac that reads contacts from your own database (Postgres/Supabase/Neon, MySQL, MongoDB, Firebase) via a read-only login and sends through your own email provider (SES, Postmark, Mailgun, SMTP)—no per-contact pricing, no data lock-in, no markup on sending costs. Ships a native MCP server so AI clients like Claude Desktop, Cursor, and Claude Code can connect your database, draft campaigns in your brand voice, and send you a test preview. Guardrails are explicit: agents cannot send, schedule, delete, or see credentials—you click Send. Includes a block editor, segments, scheduling, batch sending, domain warm-up, and bounce/complaint handling. macOS only; Windows coming. One-time license, not per-contact; 7-day trial.
