FAQ
Common questions
Does free usage have limits?
Yes. Free access is available with fair use limits so Koelio can stay fast, stable, and available to everyone.
Why is voice generation more limited than translation?
Voice generation is more resource-intensive, so its free limits are tighter than translation limits.
What happens if I reach a limit?
You may be asked to wait and try again later. Temporary limits are a normal part of the free tier.
Will these free usage terms stay the same?
Not necessarily. Koelio is currently in beta, so free usage terms and feature limits may change as the product evolves.
