ByThen has two credit types. They work differently, and knowing which is which will save you confusion later.
Free Credit
Included with every subscription plan
Used for early-stage creation: VISA setup, script generation, and Key Visual generation
Shown as a percentage gauge (0–100%)
Resets every billing cycle, unused Free Credit does not roll over
Cannot be topped up, transferred, or converted to Main Credit
When your Free Credit runs out, eligible actions fall back to Main Credit automatically.
Main Credit (MC)
Included with every subscription plan, amount depends on your tier
Used for production from Storyboard onwards: storyboarding, editor actions, TTS, music, SFX, image and video generation
Also used as a fallback when Free Credit is depleted
Shown as a number (e.g. 'MC 11,000')
Can be topped up at any time
Maximum balance: 999,999 MC
If both Free Credit and Main Credit hit zero, generation is blocked until you top up.
