Tellexa puts your governed AI assistant in your pocket. Built for teams running on the Tellexa AI platform, the app keeps work moving while you're away from your desk - chat with your assistant, capture and summarise voice notes, see your day at a glance, and stay on top of tasks, meetings and approvals. Everything stays under the same permissions, approvals and audit you trust on the Tellexa platform. WHAT YOU CAN DO β’ Chat with your assistant β ask questions and get real work done across the tools your business already uses. β’ Voice notes, summarised β record a memo on the move; Tellexa transcribes it and pulls out the key points and action items. β’ Your daily brief β start the day with calendar, email and tasks in one view, plus a traffic-aware "leave by" time so you're never late to a meeting. β’ Tasks & team reports β see what needs you today, track progress, and review team activity on the go. β’ Meeting summaries β capture the conversation and turn it into a clean summary with follow-ups. β’ Search your knowledge β find the right answer across your documents and your assistant's memory in seconds. β’ Approvals in your pocket β when your assistant needs sign-off for something sensitive, review and approve or decline it from your phone. β’ Activity & driving insights β opt-in trip and driving-behaviour insights for teams on the road. β’ Live notifications β stay informed of what matters, in real time.
