Free utilities for people who work with AI. No accounts, no upload, no catch — every one runs entirely in your browser, and says plainly what it can and can't do.
Redact emails, API keys, tokens and card numbers out of any text before you paste it into an AI. Deterministic, in-browser, honest about its limits.
See how an LLM splits your text into tokens — exact for OpenAI, calibrated estimate for Claude & Gemini — with context-window fit and cost.
Cut token-heavy text down to a lean, AI-ready version — deterministic and local, never paraphrased by a model, with a live before/after token delta.
