A: BYOK is completely optional.
On Tier 1 and Tier 2, BYOK gives you access to:
AI Model Selection Humanize Content Brand Voice
It is also useful if you want more control, prefer a specific provider/model, or want to mix providers — for example, use your own key for one model and our default key for another.

A: At the moment, we have not added a small hard limit on book size like max pages or max chapters, so we are not intentionally restricting users with a tight ceiling there.
Monthly account level creation limits still apply at all Tiers. The reason is that users can also create books and other outputs without using AI-generated sources, so creations are part of how we structure plan allowances...
It is also useful if you want more control, prefer a specific provider/model, or want to mix providers — for example, use your own key for one model and our default key for another.
So the value of BYOK is mainly flexibility, control, and access to those BYOK-enabled features on the lower tiers.
This started only a couple of hours ago after we pushed a major update. Our development team is already on it, and it should be cleaned up within the next couple of hours.
A: Yes. You can download your podcast episodes and upload to iVoox. MP3 is the safest choice for podcast uploads to iVoox based on their publishing ecosystem and examples.

if the limits do not change, then what is the point of BYOK?
On Tier 1 and Tier 2, BYOK gives you access to:

Q: Why are core promised features in Tier 3 not working at all?

In its current state, the product is practically unusable for me.
This is not...
