Dev builds interruptible two-host history podcast generator, mixing GPT, Claude and Gemini per task

Goldenchild123 · reddit · 2026-09-20

Reddit user Goldenchild123 launched Historai, an app that turns any historical topic, moment, or person into a researched two-host podcast in about two minutes, complete with sources and period artwork. Its standout feature: press the mic mid-episode to ask a question, and the hosts answer and weave it back into the story.

Rather than using one model for everything, the author ran bake-offs between GPT, Claude, and Gemini models and picked a winner for each job—research and planning, script writing, artwork selection, and voices. The differences were bigger than expected: some models write great dialogue but plan poorly, others the reverse, and costs vary widely.

You can try it without an account at historai.ca.
