AI Tools
AI-powered utilities for modern developers — prompt engineering, token counting, JSON schema generation for function calling, and cron expression building. All client-side.
AI Prompt Builder
Visually construct structured LLM prompts with role blocks, variable injection, and multi-format export.
JSON Schema Generator
Paste any JSON object and instantly generate a valid JSON Schema or TypeScript interface.
Cron Expression Builder
Visually build and explain cron expressions with next execution times and plain-English descriptions.
Why use our AI Tools?
Our AI Tools are built specifically for developers and engineers working with large language models. Whether you're crafting multi-turn prompts, generating function-calling schemas, or auditing token usage before an API call, everything runs locally — no keys, no uploads, no latency.
As AI workflows grow more complex, having the right utilities at your fingertips matters. These tools are designed to accelerate your LLM development loop while keeping your prompts and data entirely private on your device.
