Sun is an AI dialogue podcast service that turns any prompt — a topic, question, document, or calendar feed — into a multi-speaker audio podcast and publishes it to 📝Spotify or any podcast app. The company ships a Python CLI (sun-cli on PyPI) and a 📝Claude Code skill (sun-to-spotify) so coding agents can generate podcasts directly, and it operates under the 📝GitHub organization sunapp-ai, registered in February 2025 and listing a United States location.
Sun handles the full production pipeline end-to-end: research, script writing, multi-speaker dialogue, audio mixing, and publishing — the user supplies a prompt and a target duration of 5 to 120 minutes, and the service returns a finished podcast with cover art, segmented episode audio, and a manifest. The companion open-source repo sun-to-spotify, released in May 2026 under Apache-2.0, packages a curl installer plus a Claude Code skill so agents can drive generation conversationally from inside an existing workflow. A separate save-to-spotify skill handles richer Spotify packaging — cover art, in-player timeline — when needed. Sun launched on Product Hunt on May 19, 2026.
