Regarding free options, there's an example video right on the landing page. Adding more examples is not a problem: check out my newsletter at https://talkelite.substack.com/ - I launched it to showcase how voxweave makes summaries. Offering a free option is not feasible for a solopreneur.
As for Kargi it has significant limitations. you can compare
- Spelling errors.
- No free option to try, if you cant do this (cost) then put up an example video with summary so people know what they are buying.
Btw Kagi does this for free for now.
