Pricing
Last Updated: October 10, 2026
SIToolBase uses a simple prepaid credit system. You buy a credit pack once and spend credits on the tasks you run. There is no subscription and no automatic renewal — nothing is charged to you again unless you place another order yourself.
- Billing model: one-time purchase of a prepaid credit pack ("credits", shown as power in the app).
- Billing cycle: none — packs do not expire on a schedule and are not recurring. Credits are held on your account balance until they are used.
- Where to buy: the recharge page inside your account (/app/power, login required). The recharge page always shows the current price, including any limited-time promotional packs.
- Payment methods: Alipay.
- Charging rule: credits are deducted from your balance when a task is created and materialises as a running or completed task. Tasks that are rejected by content moderation or that fail are not charged.
Credit Packs
Prices are in USD. The "bonus" column shows the promotional extra credits already included in the credit amount.
Prices shown are the standard packs. A low-price trial pack and other promotional or limited-time packs (for example, discounted packs offered on selected days) are displayed on the recharge page and, where the price differs, the recharge page is authoritative. We may change prices at any time; changes never affect credits you have already purchased.
What Each Task Costs
| Feature | Credits per task | Example |
|---|---|---|
| AI Video Face Swap | 2 credits per second of video, multiplied by resolution (×1 up to 1280px, ×2 up to 1920px, ×3 above 1920px). Minimum charge is 10 seconds. | 10s @ 720p = 20 · 10s @ 1080p = 40 · 10s @ 4K = 60 |
| AI Photo Face Swap | 7 credits per image. | 20 photos = 140 credits |
| AI Watermark & Subtitle Remover | 8 credits per started block of 1,500 frames (about 50 seconds at 30 fps). | 10s video @ 30fps = 300 frames = 8 credits |
| AI Photo Restoration | 45 credits per photo. | 10 photos = 450 credits |
| AI Image Upscaler | 45 credits for 2K output · 90 credits for 4K output. | 10 photos to 4K = 900 credits |
| AI Portrait Studio | 50 credits (draft) · 100 credits (2K) · 200 credits (4K) per portrait. | 10 portraits at 2K = 1,000 credits |
Additional tools available inside the app (AI Video Replacement, AI Video Matting) are billed by output duration and are listed on the recharge page after login. The exact cost of a task is always shown before you start it.

FAQ
How do I buy credits?
Create a free account, open the recharge page (/app/power), choose a credit pack and pay with Alipay. Credits are added to your balance automatically once the payment is confirmed.
How do I check my balance and spending?
Your remaining credits are shown in the header of the app, and the recharge page lists your payment records and order status.
Do credits expire?
Credit packs are one-time purchases and are not tied to a recurring billing cycle. Credits are held on your balance and are consumed by the tasks you run.
Am I charged if a task is blocked or fails?
No. Content blocked by our moderation system before generation, and tasks that fail, do not consume credits. Only tasks that run or complete are charged.
Can I get a refund?
Refunds are governed by our Refund Policy. Unused credit packs may be eligible; used credits and terminated accounts are not refundable.
Why was my task rejected for content reasons?
All prompts and generations are subject to our Acceptable Use Policy. If you believe a decision was wrong, you can appeal at [email protected].
