Llm Application Engineer

There are over 5 billion users using basic applications today such email, notes, tasks, calendar and they’re not AI-native. Our mission is to build proactive applications for anyone in the world, who are not used to complex prompting. We aim to bring intelligence to conversations, errands, organising and workflows, with minimal to no prompting.Our product focuses on achieving high reliability for long-running workflows, persistent context, and real-world task completion. We believe products will greatly reduce hallucinations.Our objective is to organise anyone’s life, allowing us all to spend time on valuable and meaningful things.About ActAIThere are over 5 billion users using basic applications today such email, notes, tasks, calendar and they’re not AI-native.
