Own weekly pool

0.5 – 1.5 credits

Reset cadence: credits refill every Monday at 00:00 UTC. The AI detector has its own separate weekly allowance — 10 scans/week on Free, 200 on Pro, unlimited on Studio — that never draws from your humanize credits.

Local media by architecture

Images, video and detector scans are processed locally. Light-mode text is local; deeper text modes use the disclosed inference route.

Weekly credits, no surprises

Credits reset every Monday at 00:00 UTC. No rollover, no overage charges, no auto-upsell. Cancel anytime in one click.

Cancel, downgrade, or pause

Manage everything from your hub. Cancel keeps your plan active until the period ends — you never lose paid time.

Commonquestions

Anything else? Drop us a line — we answer every billing question within 24 hours.

What counts as a credit?+

One photo humanize = 1 credit. One short video humanize = 2 credits. Batches of 10+ photos drop to 0.5 credits per image. Text humanize costs 0.5 (light), 1 (standard), or 1.5 (aggressive) credits per run. The detector runs on its own weekly scan allowance (Free 10 / Pro 200 / Studio unlimited), separate from humanize credits.

When do credits reset?+

Every Monday at 00:00 UTC, weekly. Unused credits do not roll over — the model is designed for predictable, sustainable throughput rather than hoarding.

Can I switch plans mid-cycle?+

Yes. Upgrades take effect immediately and the new credit pool is available right away. Stripe prorates the price difference automatically through the billing portal.

What happens if I cancel?+

You keep Pro or Studio access until your current billing period ends — you don't lose paid time. After the period, the account drops to Free automatically.

Is there a free trial for Pro or Studio?+

There's no separate trial — the Free plan is the trial, permanently. Same humanize engine and detector with no watermark, just a weekly cap (3 credits, 10 scans), the generic camera profile and Light-mode text. Upgrade whenever you need more; cancel anytime and keep access until the period ends.

Do you store my images or videos?+

Image and video bytes stay in the browser. Images use TypeScript, Canvas and Web Workers; video uses ffmpeg.wasm. The backend stores metadata-only quota records, not the media itself.

What if a platform updates its detector?+

We track public classifiers (Hive, Optic, Illuminarty, Sensity, plus platform-side detectors) continuously. Pipeline updates ship to all paid tiers automatically — no version migrations.

Can I get a refund?+

You can cancel anytime and keep Pro or Studio until the end of the paid period — nothing is charged after that. EU consumers also have a 14-day right of withdrawal before first use (Terms § 6). We don't refund partial periods, but if something was billed in error, email us and we'll fix it.
