VoiceCap
Su ideja, MB
An EU-hosted AI notetaker that records in-person and online meetings and returns speaker-named transcripts, summaries and action items.
Key features
- Three Capture Paths: Record in the room from iOS, Android or the browser, upload MP3/M4A/WAV/MP4/MOV files, or send a bot into a Zoom, Meet, Teams or Webex call.
- Calendar Auto-Recording: Connect Google or Outlook calendars and scheduled online meetings are joined and recorded without anyone pressing a button.
- Speaker-Named Transcripts: Transcribes 100+ languages with automatic detection and separates speakers by name, with timestamps on every line.
- Decision Tracking: Proposes the decisions a meeting contained along with the reasoning and the options that were rejected; confirmed decisions are linked from later meetings so settled calls are not re-argued.
- Action Item Extraction: Pulls out commitments with an owner and a due date rather than leaving them buried in the transcript.
- Company Memory Search: Meetings sort themselves into projects, and one search covers transcripts, summaries and decisions with results linking to the exact second.
- MCP Access for AI Assistants: A read-only MCP server lets Claude and ChatGPT answer questions about who owns what or what changed, limited to meetings the asker could already open.
- EU Data Residency: Recordings and derived data stay in EU data centres under GDPR, are never used for training, and can be deleted on request.
Best for
- Client Consulting: Keep an accurate billable record of client sessions without taking notes during the conversation.
- Legal and Compliance: Document every commitment made in a negotiation or board meeting, with the decision and its reasoning attached.
- Sales Follow-Up: Send a shareable summary and action items within minutes of a call so follow-up matches what was actually agreed.
- Multilingual Teams: Transcribe Baltic, Scandinavian and other smaller European languages that mainstream notetakers handle poorly, and pick the summary language separately.
- Research Interviews: Transcribe field interviews or site visits recorded on a phone and search the archive later for a specific quote.
- Assistant-Driven Recall: Ask Claude or ChatGPT over MCP what a project decided last month instead of scrolling through meeting notes.
