ReasoningDensity
See where your AI API cost & tokens go — no API key needed
Upload your OpenAI, Claude, or Gemini usage export. Find token waste, model overkill, and failed-request cost — instantly, in your browser. No API keys, no server upload.
Hey everyone!
I've been building a few side projects using Claude (haiku, sonnet, opus, fable) and ChatGPT, picking models depending on the task — heavier models for detailed coding/audits, lighter ones for simple stuff. But my API usage kept climbing and I honestly had no clear picture of where the money was going.
Every tool I found wanted an API key connected or an account just to check usage, which felt like overkill for something I just wanted a quick answer to.
So I built ReasoningDensity — you drop in your usage CSV (works with OpenAI's and Anthropic's exports) and it shows a cost/token breakdown per model, plus plain-language flags like "this model costs 6x more per call than that one." Runs entirely in the browser, nothing gets uploaded anywhere, no signup.
Still pretty early — no accounts, no saved history yet, just upload and see. Would love feedback, especially from anyone who's tried other provider exports (Gemini support is still rough).
Thanks for checking it out!
The fact that everything runs in the browser without touching a server is genuinely impressive. Most token dashboards feel sketchy because they demand API keys, but skipping that step entirely makes this feel trustworthy from the first click.
Dropped in my OpenAI export and it immediately flagged a bunch of oversized gpt-4 calls I'd been ignoring for months. Loved that nothing left my browser.
Love that it runs fully in the browser, feels way safer than uploading usage data anywhere. One thing that would help me actually act on the findings: a "potential monthly savings" estimate per category next to each flagged issue, so I can quickly prioritize which switches or prompt fixes actually move the needle on my bill.
