Plans & historical pricing
Nero AI web plans (Free / Standard / Yearly promo / Business); USD · 2026-10-21
Public page displays only the 7.66 USD/month equivalent without showing the annual invoice total before login.
4 plan / billing-period records, all listed; — means that period is not recorded.
The official pricing page and credit table state that guests get 5 free runs and registered Free accounts receive 10 one-time Nero Credits (Standard/Photo/Anime 2× costs 1 credit/image, 4× costs 2 credits/image, paid-only 8× costs 4 credits/image). Standard monthly is USD 21.95/month promotional (regular USD 24.99/month, 300 credits/month). The yearly promo banner displays only "7.66 USD per month" (3,000 credits/year) without printing the annual invoice total before login, so the annual total is marked unverified.
Verification has gaps; unknown prices and quotas are not inferred.
Cancellation, sources & verification record
Cancel anytime by turning off auto-renewal in account settings (remaining credits expire at the end of the billing period); FAQ states refunds are not allowed once Nero Credits have been used.

Tested result & sample
High foreground recall (99.87%) and near-zero background leakage (0.015%), with slight resolution loss from the 2000×2000 free-tier input resize and moderate smoothing on fine peripheral hair wisps.
- Edge error MAD
- 0.0886 · Lower is better
- Global error SAD(k)
- 40.647 · Lower is better
- Foreground retention
- 99.870% · Higher is better
- Background residue
- 0.015% · Lower is better
These historical measurements describe alpha error at edges (MAD), total alpha error / 1000 (SAD), foreground retention and background residue. Low-resolution outputs are aligned to the reference under the original protocol; this does not imply a full-resolution export.

- Network-observed server wait

Network wait includes round trips, queuing and polling error, not pure inference time. Local timings depend on the device; repetition counts are not standardized in legacy records.
Experience, rules & trust
- Disclosure
- Explicit modal before processing informs the user of the 2000×2000 free resize rule and 1-credit cost
- Interaction
- After confirming 'Resize & Continue' and 'Start (1 Nero Credits)', the workspace provides a clean split/toggle preview and a direct 'Download' button ('Download HD') that exports a 2000×2000 transparent PNG without watermark or paywall ambush.

| Pricing transparency | 27 / 35 | Landing page offers immediate upload entry; uploading our 2048×2048 anchor pops up an explicit pre-processing notice ('Image exceeds 2000*2000 (Pro allows up to 4000*4000). Auto-resize to 2000×2000 for free processing') and clearly displays 'Start (1 Nero Credits)' alongside remaining free balance ('Free: 5 left') before execution. | Evidence A → |
| Interaction restraint | 25 / 30 | After confirming 'Resize & Continue' and 'Start (1 Nero Credits)', the workspace provides a clean split/toggle preview and a direct 'Download' button ('Download HD') that exports a 2000×2000 transparent PNG without watermark or paywall ambush. | Evidence A → |
