Free LLM setup

+

+ LexAI is free — no subscription, no LexAI account. To use it at $0 ongoing, connect a + provider that offers a free API tier. Groq and OpenRouter are the most practical; Anthropic + and OpenAI offer small trial credits but not a permanent free API. +

+

Recommended path

+
    +
  1. + Install LexAI (Chrome, VS Code, or CLI) — see Install. +
    2. +
  2. + Sign up for Groq{' '} + (no credit card) or{' '} + + OpenRouter + {' '} + (no card for free models). +
    3. +
  3. Create an API key on that provider's dashboard.
    4. +
  4. + In LexAI: choose the provider, paste the key, and set the model slug below (Chrome + Options → Model; VS Code Settings → Model; CLI{' '} + LEXAI_MODEL). +
    5. +
  5. Select text and run an action — requests go directly to your provider, not LexAI.
