What we build
We’re building AI that understands how people actually speak
Our own speech models
We train our own speech models for languages, dialects and conversations. Pianissimo, our open model for Swedish, is fast enough for real time and runs locally on an ordinary laptop.
Read about PianissimoOpen research
We share what we learn so others can build on it. On Klang Research you’ll find our papers and Klang Dialects, an open dataset for testing speech recognition on Swedish dialects.
Go to Klang ResearchThe product
Klang is the perfect memory of all the conversations in your organisation. It records, transcribes and summarizes your meetings, so you can be fully present and still leave with everything. Your AI agents can work with it too. Through MCP, API and CLI, Claude, Gemini or your own agents can search your conversations and act on what was said.

Built on European values
Klang is built in Sweden, on European values: openness, accountability and trust. Those values travel with Klang, wherever in the world you use it.
This matters now more than ever. AI must be built in a way that protects people's data and is grounded in trust from the start.
With Klang, you're choosing a different kind of innovation. Which we think is great. Necessary, even.
