Which AI Provider Can Do What?

What it does: One page to answer "why is this feature greyed out / erroring?" — every feature × every provider, plus how to combine providers smartly.

The matrix

Practical pairings

• "I want everything from one key" → OpenAI or Gemini (writing + images + vision + search).
• "Best writing, images secondary" → Claude for text; note you’ll have no image generation — pair with a second provider when you need images.
• "Minimum cost" → OpenRouter with a ★ FREE model for writing; expect variable quality, and remember free-model providers often retain/train on prompts.
• "Maximum privacy of drafts" → any paid API tier (paid API traffic is generally excluded from training by the major providers — check your provider’s current terms).

Switching providers

Keys are stored per provider — switching the Active Provider in settings is instant and non-destructive. A common pro setup: bulk-write a batch on a cheap/free model, then regenerate the most important articles on a flagship model.

Where the model choice shows up

Every generation uses whatever Model / Image Model is selected at that moment — articles, meta, transforms, bulk jobs, images. The Reporting page records usage per model so you can compare real costs.
