AI image tools
Beyond generation, Picora offers a toolkit of AI image tools that operate on images already in your library. Each runs on demand and is billed per use from your Credit wallet.
The tools
| Tool | What it does | Output | Relative cost |
|---|---|---|---|
alt_text | Generates an SEO-friendly description of the image | Text | Lowest |
auto_tag | Extracts bilingual (EN / 中文) tags | Tags | Lowest |
smart_crop | Detects the subject and crops to a chosen ratio (1:1 / 4:3 / 16:9 / 9:16) | New image | Standard |
bg_remove | Removes the background, returns a transparent PNG | New image (PNG) | Standard |
ocr | Extracts text from an image or PDF into Markdown (with formulas & tables) | Markdown | Higher |
The exact cost is shown before you run a tool. Tools that produce an image (smart_crop, bg_remove) save the result as a new image in your library; text tools (alt_text, auto_tag, ocr) return their result as text/Markdown.
Using a tool
In the dashboard, open an image and switch to the AI Processing tab, then pick a tool. Via API:
GET /v1/ai/tools— list all tools with current specs & pricingPOST /v1/ai/{tool}— run a tool on an image ({ imageId }or{ imageUrl }, plus tool-specificoptions)GET /v1/ai/logs— your processing history
Billing works like generation: the cost is pre-charged, deducted on success, and refunded if the tool fails. Re-running the same tool on the same image with the same options within 24h is de-duplicated (you won’t be charged twice).
Availability
AI image tools require a Pro or Pro+ plan. On Trial (or without a plan) the tools are shown but gated behind an upgrade prompt.
