Building tools for developers working with AI

Hi everyone! 👋

I'm a developer interested in building practical tools around AI and LLMs.

Recently, I've been working on TokenCalculator, a free toolkit that helps developers understand token usage, estimate LLM costs, and compare different AI models.

I'm joining Product Hunt to learn from other makers and developers, share what I'm building, and get feedback on ideas that could make AI development easier.

I'm especially interested in hearing how other developers currently manage token usage and LLM costs in their projects.

What AI developer tool or workflow has saved you the most time recently?
