ChatLite

ChatLite saves you or your company from expensive monthly AI subscriptions. Just create an API key to use LLMs / GPTs on-demand (pay-as-you-go) on ChatLite.

The benefits of ChatLite for you:

• Pay-as-you-go AI chat can reduce spend by over 80% vs monthly subscriptions.

• Use all the latest LLMs from OpenAI (GPT-4.1, o3, o1), Anthropic (Claude Sonnet 3.7, 4.0, Opus 4.0), Google (Gemini 2.5 Flash, Pro), Perplexity (sonar), DeepSeek, and over 300 models from OpenRouter directly inside Excel, Powerpoint, or Word.

• Your conversations and API keys are encrypted and stored locally, never on our servers.

• Conversation history is organized per document, reducing clutter.

• LLM providers offer sophisticated API management including usage statistics, auto top-up, spending limits, and multiple keys for accounting purposes.
