A studio for software
that's built well.
We use AI to work fast, and we're careful about the rest.
We build software that
didn't exist yesterday.
Custom AI software
We build AI tools for companies that need something specific. No templates, no off-the-shelf — just the tool your team actually needs.
Our own products
We ship our own software under the Quelm name. TokenCapAI is the first — spend enforcement for teams running AI agents. Building products of our own keeps us honest about what's hard.
Problems we thought were worth solving.
Built with AI.
TokenCapAI
AI cost control. Per customer. Actually enforced.
TokenCapAI puts a real-time spending limit on every customer, team, or agent, and blocks calls the moment a budget is hit, so overspend stops before it lands on the invoice. Hard caps hold the limit even under concurrent load, for anyone billing customers for AI or running regulated workloads. The same per-customer data lets Finance invoice on exactly what was used. Works across OpenAI, Anthropic, Gemini and 200+ models with sub-50ms enforcement.
Quietburn
Burnout detected. Privately.
An offline AI journaling companion that watches your entries over time and warns you about burnout before you notice it yourself. Runs entirely on your device — no data ever leaves your machine.
