Guide for Free Usage

Companion uses a bring-your-own-key model.

That means LearnKit does not require a separate subscription for AI features. If your provider offers free usage, you can use Companion on that free tier.

The simplest free-start path is OpenRouter.

  1. Open Settings -> Companion.
  2. Turn on Enable Companion.
  3. Set AI provider to OpenRouter.
  4. Set OpenRouter model catalog to Free.
  5. Paste your OpenRouter API key.
  6. Pick a free model, or start with Auto Router.

If one free model is busy or rate-limited, switch to another one.

LearnKit’s Companion settings explicitly support OpenRouter’s free model catalog and keep router models pinned at the top.

That makes it the most straightforward provider for trying free usage without guessing model IDs.

To reduce failures and unnecessary token use:

  • keep generated card counts small while testing
  • disable flashcard types you do not need
  • avoid image-heavy prompts unless you know the model supports vision
  • keep prompts short and specific
  • use text-only workflows first, then add attachments later if needed

Free tiers are useful, but they are less predictable than paid models.

You may see:

  • slower responses
  • rate limits
  • temporary unavailability
  • lower quality outputs
  • weaker attachment or vision support

If a free model fails, try another model before changing the rest of your setup.

API keys stay in your local LearnKit plugin data.

Do not commit your key file to a public repository.
