HandyAI offers developer utilities for token counting, prompt analysis, JSON tool use conversion, and cost calculation.
About HandyAI
HandyAI provides free single-purpose utilities for working with large language models. Its live tools include an LLM Token Counter that counts tokens for Claude, GPT-4, and Gemini models side-by-side with per-call cost estimates, and an AI Cost Calculator that projects monthly API costs across those model families.
Only the token counter and cost calculator are marked as Live. Other listed items, such as schema conversion, prompt analysis, and cron explanation, show planned release quarters in 2026-2027 with email notification prompts. The live tools are described as entirely in-browser and require no sign-up.
