Markus Kellermann

Markus Kellermann is a solo German developer who concentrates on productivity utilities that remove friction from everyday digital communication. His only public offering, Convo, is an AI-driven conversation and meeting assistant that runs unobtrusively on Windows desktops. The program listens to local audio or imports recordings from Teams, Zoom, Google Meet and similar services, then applies speech-to-text and large-language-model analysis to generate concise multilingual summaries, searchable transcripts, action-item lists and calendar-ready minutes. Typical users are project managers who need to circulate polished notes within minutes, consultants who bill by the hour and want accurate records, journalists transcribing interviews, and students capturing lecture content for later review. Because the engine works offline once models are cached, sensitive corporate or legal discussions remain on-device, while an optional cloud mode accelerates processing for larger files. Convo also integrates with Outlook and Gmail to attach notes automatically to the corresponding event, and exports to Markdown, DOCX or PDF so the output can be dropped into any reporting workflow. The lightweight installer adds context-menu entries and a system-tray icon for one-click recording, yet keeps CPU use low enough for simultaneous video calls. Markus Kellermann’s software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always fetch the newest release, and can be queued for batch installation alongside other applications.
