Team memory of meetings and calls, on our own speech models
25 followers
Klang is a memory of all your organisation's important conversations. Record meetings in the room, calls and online meetings with the iPhone and Android app, the Mac and Windows apps (beta) or the web. Klang connects them into one shared repository you can search, question and analyse, or open to your AI agents through MCP. Under the hood, we're an AI speech lab: we train our own speech models, like Pianissimo, our open model for Swedish and Danish. Built in Sweden. Free to start.

Hi Product Hunt, I'm Andreas, co-founder and CTO of Klang.
Klang is a memory of all your important conversations, shared across your organisation instead of scattered in people's notes. Under the hood, we're an AI speech lab. Most large speech models are trained mainly on English, and other languages fall behind. So we train our own.
Our open model, Pianissimo, covers Swedish and Danish today. Norwegian is next, and more languages will follow. It transcribes an hour of audio in about a second on a single server GPU, and is small enough to run locally on an ordinary laptop. In our Danish tests it had the lowest error rate of the open and closed models we compared. The weights are open under CC BY 4.0, and our research is at research.klang.ai.
What Klang does today:
Records conversations where they happen. The iPhone and Android app records meetings in the room and phone calls. The desktop app for Mac and Windows, both in beta, records online meetings with no bot. Or the Klang assistant joins your calendar meetings.
Keeps transcripts, summaries and to-dos in one repository your team shares.
Answers questions across all of it, with sources you can check.
Runs scheduled analyses, like a weekly summary of sales call objections.
Opens your conversation memory to Claude, ChatGPT or your own agents through MCP, API and CLI.
Klang is built in Sweden and hosted in the EU. We're ISO 27001 certified, and we never train AI models on your conversations.
There's a free plan that doesn't expire. I'd love to hear where your important conversations get lost today, and which language you'd like us to train next.
