Tokenwise

Your AI cost & performance copilot. Save 30%+ on LLM API costs with one line of code.

Production visibility into every LLM call: cost, latency, errors, and quality, in real time. Drop-in proxy · <50ms overhead · keys never stored · observe-only by default, no prod changes. A drop-in proxy at the edge, under 50ms of overhead, and your provider keys never stored. Point your app at our drop-in proxy — one line, no SDK rewrite. Every call lands with cost, tokens and latency, sliced by model, app, or tag. One-click fixes: model swaps, caching, prompt trims.
