PaintBox

How AI works in PaintBox

Your taste stays on your machine. The AI runs on Bike4Mind.

Every manual tool runs in your browser and costs nothing. When you ask for AI, the request goes through Bike4Mind, an enterprise AI platform with 60+ models, which handles who can do what, what it costs, and what's allowed. You choose which models are used.

The architecture

Four layers. Only the ones you use are involved: if you never ask for AI, nothing leaves your browser.

You: Your browser

Models: AI providers

  • AnthropicA fast model handles simple requests; bigger ones go to Sonnet, or Opus for the hardest, which plans the operations and their exact settings
  • Image generation · optionalOpenAI GPT Image, Black Forest Labs Flux, Google Gemini
  • Voice · optionalSpeech-to-text and spoken replies
Runs on your machine, never uploadedOptional: used only if you allow itBike4Mind: identity, credits, moderation, models
Bring an AI you already use. Connect Claude, ChatGPT, Cursor or your own script over MCP, free on every plan while you watch and approve its edits; the $10 plan is for work that runs without you. It doesn't need Bike4Mind's models at all: the operations themselves run deterministically and cost no credits. Anything it changes arrives as a proposal you approve. If it asks for AI image work, you see the estimated cost first, and it runs on your credits only if you accept it. Claude's free plan allows one custom connector; ChatGPT's connectors need a paid ChatGPT plan (as of Nov 2026).
Or use Bike4Mind's AI. Ask in plain words or by voice. Bike4Mind picks the model, checks your permissions, credits and limits, and PaintBox's planner turns the answer into the same typed operations, so it's repeatable and reviewable.

You type or say“Warm up the sky on all 40 product shots and give me a square crop of each for Instagram.”

    no credits
  2. A fast model reads the requestSimple requests it answers itself. Anything bigger goes on to Sonnet, or Opus for the hardest.
    a few credits
  3. The planner works out the operationsWhich documents, which operations, in what order, and their exact settings: the sky selection, the warmth adjustment, the crop box.
    a few credits
  4. PaintBox runs the operationsThe editor engine applies them to the shots in batches. The same operations give the same pixels every time.
    no credits
  5. Generation only if neededIf a step needs new pixels, it calls the image model you chose: Generative Expand, for one, extends a picture past its edges with AI-painted pixels. Skipped otherwise.
    ≈ 5–12¢ per image, by model, only if used
  6. You review the proposalStep through the 40 results; accept all, reject some, retouch two by hand.

  7. Credits settleBike4Mind charges what the models cost plus 20%. Credits you don't use carry over, and each month's credits last 90 days.

Today the in-editor assistant works on one open document at a time; batch runs across many documents are coming. An AI you already use, like Claude or ChatGPT, connected over MCP, can already do most of this journey now.

How AI credits work

One credit is $0.0006. Bike4Mind charges what the models cost plus 20%, which covers payments, storage and serving. Everything you do by hand, and every operation an agent runs, is free.

Uses your Bike4Mind credits: AI image work (generating a picture, Generative Expand, an AI edit of a selected area), the built-in assistant in the Conversation panel, and voice transcription. Costs no credits: editing by hand, and an AI you already use, like Claude or ChatGPT, using PaintBox’s editing tools.

That AI spends your credits only on AI image work you accept after seeing its estimated cost, or within a daily cap you set if you give it the Generate permission. Your Claude or ChatGPT plan is billed by Anthropic or OpenAI, separately from Bike4Mind credits.
