Slideshow City is a presentation management solution that helps AV teams and stage managers handle the full lifecycle of conference presentations in one system. It covers speaker file uploads, automated format validation, review and approval workflows, live stage transitions, and digital signage across multiple rooms. The platform is designed for professional multi-session events such as medical symposia, academic conferences, and corporate meetings. Speakers upload their files through a portal where the system checks formats, fonts, codecs, and dimensions. AV teams review and approve presentations before they reach the stage, reducing the risk of technical issues during live sessions. Key capabilities include: - Centralized control room for managing back-to-back sessions, launching slide decks, and keeping multi-room events on schedule, with built-in vMix and Bitfocus Companion integration for hardware control surfaces like Elgato Stream Deck - Automated presentation validation supporting PowerPoint, Keynote, and PDF, flagging format issues before files go live - Self-check kiosk mode where speakers preview and verify their slides independently before going on stage - Digital signage that updates room screens, lobby monitors, and stage displays automatically with speaker names, session titles, and timing - Speaker room management with check-in tracking, preview stations, and visibility into who has arrived and verified their materials While the platform runs in the cloud, its local applications distribute presentation files across rooms over the venue's local network. This avoids internet speed bottlenecks and keeps large files moving between stage machines, even in venues with limited connectivity. Slideshow City syncs with Registration Town, Summitware's conference registration product, so speaker data, schedules, and program updates flow between the two systems automatically. It also offers a REST API, CLI, and MCP for custom integrations. Target users include AV teams, stage managers, and conference organizers managing events with multiple sessions and speakers.
