Pricing
Start free: one polished frame a day
Registration is free, and every account earns a daily check-in of 6 credits — exactly the price of one standard frame. Check in, cut a frame, and judge the bench on real output before a single credit is bought. There is no card requirement and no trial countdown; the check-in simply runs every day you show up.
Pay per job, know the price first
DiamondBio runs on credits. Every tool shows its exact credit cost on the job, before you confirm it — there are no surprise charges, and a job that fails refunds its credits automatically. Credits come from one-time packs (no subscription) and from the daily check-in.

Credit packs
The standard pack is $19.99 for 1,000 credits, bought once and spent as you cut — at the standard image price, that is over 160 frames. Larger one-time packs are shown in the checkout with their exact totals before you pay. There is no subscription and no auto-renewal.
Bench budgeting notes
- Prototype at standard. Brief and cull at 6 credits; spend premium prices only on frames that already proved themselves.
- Polish sparingly. Upscalers are finishing steps. Budget them for covers and paid tiers, not for routine tiles.
- Failures are free. A failed job refunds automatically, so the budget risk sits in choices, not in outages.
