About FreeAI.DevTools

As AI developers ourselves, we found it frustrating to constantly look up pricing across multiple provider websites, manually calculate API costs, and estimate token counts for different models. We built FreeAI.DevTools to solve these problems with a single, unified toolkit. Every tool runs 100% in your browser; your data never leaves your device, making it safe to use with proprietary prompts, sensitive code, and confidential data.

We offer 12 free tools organized into three categories: AI Tools (token counter, cost calculator, model comparison, prompt generator, system prompt builder), Developer Tools (JSON formatter, Base64 encoder/decoder, UUID generator, epoch converter, cron generator), and Text Tools (word counter, text case converter). We update pricing data regularly to ensure accuracy.

FreeAI.DevTools is built and maintained by BlueOrbitAI, a team passionate about making AI development more accessible. We believe developers should have free access to essential tools without subscriptions, sign-ups, or data collection. Follow our educational content on YouTube at “The College Of AI” for tutorials, model reviews, and AI development guides.

All pricing data is sourced directly from official provider documentation and APIs: OpenAI's pricing page, Anthropic's API documentation, Google Cloud's Vertex AI pricing, xAI's developer docs, DeepSeek's pricing page, Mistral's API documentation, and Meta's Llama model cards. Data was last verified in April 2026.
