AI Tools
Free online AI tools for developers working with large language models. Count tokens, compare AI models, and chunk text for RAG applications - all running locally in your browser with no signup required.
What are AI Tools?
AI tools are software utilities designed to help developers build, optimize, and evaluate applications powered by large language models (LLMs) like GPT-4, Claude, and Gemini. Our collection includes token counting for accurate prompt engineering, side-by-side model comparison for choosing the right LLM, and text chunking for retrieval-augmented generation (RAG) pipelines.
Common Use Cases
- Calculate token counts for prompts before sending to GPT-4, Claude, or Gemini APIs to estimate costs and avoid context limits
- Compare AI model pricing, context windows, and capabilities to choose the right LLM for your project
- Split long documents into semantic chunks for RAG applications and embedding generation
- Estimate API costs for input and output tokens across different AI providers
- Prepare training data and prompts with accurate token budgeting
