An EU-hosted AI notetaker that records in-person and online meetings and returns speaker-named transcripts, summaries and action items.

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.

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.

Gives an AI agent its own isolated virtual display on your Windows machine, so it can drive real desktop apps while you keep using your desktop.

Isolated Virtual Display: Creates a dedicated second display for AI inside your existing Windows session, so the machine is shared but the workspace is not and the agent never competes for your cursor.
Scoped Application Access: You choose which applications and resources the AI can reach and what it may interact with, replacing uncontained desktop access with a boundary you draw.
Automatic Prompt Blocking: UAC prompts and desktop notifications are blocked from entering the AI's workspace, keeping system dialogs and interruptions out of the agent's reach.
Real-Time Observability: The agent's display can be watched live as it works, so you see what it is doing rather than reconstructing it from logs afterwards.
Interactive Takeover: You can take control of the virtual display yourself at any moment and let the AI resume from where you left off when you are ready.
Parallel Workspaces: Multiple tasks run simultaneously, each with its own virtual display and its own resolution, so several AI processes work at once without colliding.
GUI Application Support: Agents open and operate existing desktop software — CAD, simulation, creative and specialized research tools — with no need to rebuild the applications for AI.
Bring Your Own Keys: You supply your own model provider credentials and pay Anthropic, OpenAI, Google or your preferred provider directly rather than buying tokens through ZeroSphere.

GUI Test Automation: A developer has an agent launch the application being built, interact with its interface, inspect what happens and iterate — work a terminal-only agent cannot do.
Bug Reproduction: An engineer sends an agent to reproduce a reported defect in a real running app and observe the failure, while continuing to work on their own desktop.
CAD and Simulation Workflows: An engineer delegates repetitive operations in specialized engineering software that has no API surface for automation.
Safe Agent Experimentation: A team trials computer-use agents without giving them access to personal files, system settings or financial applications on the primary desktop.
Creative Tool Operation: A designer lets an agent perform routine steps inside visual and creative applications on the same machine where the source files live.
Parallel Task Execution: A developer runs several agent tasks at once, each in its own display, instead of serializing them through one shared screen.
