AI Central puts your organisation's AI assistants in your pocket. Each assistant knows one part of your business. It remembers what it has been told, and it can act — read a document you send it, query a system your team has connected, produce the report you asked for. This app is a client for the Graf AI platform: the same account and the same conversations as the web console, so a thread you start at your desk continues on the train. WHAT YOU CAN DO • Talk to any assistant your account can reach, with replies streaming in as they are written. • Pick up an earlier conversation instead of starting over. • Send a file or a photo up, and download what an assistant has produced. • See what an assistant runs on a schedule — when it runs next, whether the last run failed and why — and pause one or run it now. • Check which channels and credentials an assistant has, and which it is missing. • Get a notification when a long reply has finished, so you do not have to sit and watch. BUILT FOR THE WAY THE WORK IS ORGANISED Assistants are grouped by the organisation they work for, with the group pinned as you scroll — useful when you carry a lot of them. Search matches names, roles and organisations at once. You only ever see assistants your account has been granted, exactly as in the browser. WHAT YOU NEED An account on the Graf AI platform, created for you by an administrator. There is no sign-up in the app; if you do not already have an account, the app cannot create one for you. ABOUT YOUR DATA Conversations are stored on Graf Clouds servers so that the phone and the web console show the same history, and the text is sent to an AI model provider to produce each reply. The app itself carries no analytics, no crash reporting and no third-party SDKs. The full detail is at grafclouds.com/ai-central/privacy/.
