Questions & Answers

As answered by people managing UtilityLab.dev and OpenAI.

What makes your product unique?

UtilityLab.dev's answer

Most LLM cost calculators are either spreadsheets or require signing up for an API. AI Cost Simulator is a free, browser-based tool that works instantly โ€” no account, no installation, no data upload. It supports the widest range of models (GPT-4o, Claude 3.5 Sonnet, Gemini 1.5 Pro, DeepSeek V4 Flash, and more) with both per-call and monthly volume estimates in one view.

Which are the primary technologies used for building your product?

UtilityLab.dev's answer

Vanilla JavaScript, HTML, and CSS โ€” no frameworks, no bundlers. All cost calculations happen client-side. The tool is deployed as a static site on Cloudflare Pages for global low-latency access.

Why should a person choose your product over its competitors?

UtilityLab.dev's answer

It's the only zero-friction cost estimator. Competitors either lock features behind sign-up walls, only support one model family, or require you to dig through separate pricing pages. AI Cost Simulator gives you a side-by-side comparison of all major LLM providers in one page โ€” and everything runs locally in your browser, so your pricing data never leaves your machine.

How would you describe the primary audience of your product?

UtilityLab.dev's answer

Developers, indie hackers, and technical founders who are evaluating LLM APIs for their next project. Also product managers and engineering leads doing cost analysis before committing to a model provider at scale.

What's the story behind your product?

UtilityLab.dev's answer

When building AI-powered features, we realized every model provider publishes pricing differently โ€” per-token, per-character, per-request โ€” and there's no single place to compare them. Instead of bookmarking five pricing pages and building a spreadsheet, we built a dead-simple comparison tool. We open-sourced the approach and made it free so other developers don't have to waste time doing manual math.

Who are some of the biggest customers of your product?

UtilityLab.dev's answer

Since it's a free browser tool with no sign-up, we don't track individual users. It's used by developers and teams evaluating LLM costs across startups, agencies, and enterprise engineering teams.
