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

ToolWhat it doesOutputRelative cost
alt_textGenerates an SEO-friendly description of the imageTextLowest
auto_tagExtracts bilingual (EN / 中文) tagsTagsLowest
smart_cropDetects the subject and crops to a chosen ratio (1:1 / 4:3 / 16:9 / 9:16)New imageStandard
bg_removeRemoves the background, returns a transparent PNGNew image (PNG)Standard
ocrExtracts text from an image or PDF into Markdown (with formulas & tables)MarkdownHigher

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 & pricing
  • POST /v1/ai/{tool} — run a tool on an image ({ imageId } or { imageUrl }, plus tool-specific options)
  • 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.
