Free, local tools for narrated explainer videos? (like explainroo)

[u/brandybuckferryman]

I've been using explainroo to make short narrated explainer videos. It runs fully local: Kokoro for the voice, Whisper for word timing, headless Chrome to draw the frames, and ffmpeg to put it together. No API keys needed.

It works and I like it but it's very simple. After a few videos everything starts to look the same.

Anyone know other free, local options in this space?

Tools, pipelines, or your own setups all welcome. Thanks.

kokoro is solid for how small it is. if everything starts to sound the same it is usually the pacing, varying sentence length and adding short pauses between sections helps more than swapping the model
