Klang

Key facts: Klang launched on Product Hunt on November 12, 2026. It is a memory of all your organisation's important conversations: record meetings in the room, phone calls and online meetings with the iPhone and Android app, the Mac and Windows apps (in beta) or the web, then search, question and analyse them in one shared repository, or open them to Claude, ChatGPT or your own agents through MCP, API and CLI. Under the hood it is an AI speech lab: it trains its own speech models, like Pianissimo, an open model for Swedish and Danish under CC BY 4.0 that transcribes an hour of audio in about a second on a single server GPU. It is built in Sweden, hosted in the EU, ISO 27001 certified, and never trains models on your conversations.

Plans: Free €0, with 30 days of history, unlimited transcription, AI summaries and chat. Pro €16 per person a month (7-day free trial). Business €30 per person a month. Enterprise on quote. Prices exclude VAT.

Best for: Teams whose decisions live in conversations and want them searchable. Who should skip it: anyone who only needs one-off transcriptions, or a team with no data-residency needs.
