Fluide (formerly Atlas Copilot) is AI-native adaptive learning for work. Start with the outcome. Fluide builds the path, teaches the skill, and proves you can do the job. Stop finishing courses. Start getting ready to perform. LEARNING THAT ACTUALLY ADAPTS Explanations, visuals, practice, and coaching change with you, your role, your level, and where you are stuck. If something does not land, Fluide tries another way until it sticks. AN AI TUTOR THAT TEACHES Talk or type. Fluide explains, asks, visualizes, and coaches in the moment. Voice guidance and real-time visuals keep you moving, not waiting for the next module. PRACTICE THAT FEELS LIKE THE JOB Roleplay the conversations that matter: objections, feedback, 1:1s, customer calls. Realistic scenarios test what you can do, not what you can recall. BUILT AROUND THE OUTCOME Tell Fluide what people need to be able to do, ramp into a role, handle objections, use AI at work, follow a process, lead better conversations. Fluide generates a guided path around that goal. WHAT TEAMS USE FLUIDE FOR • Onboarding that gets new hires ready to perform • Leadership conversations and decisions • Sales enablement and objection handling • Practical AI enablement in real workflows • Compliance people can actually apply • Customer education that drives adoption SEE WHO IS GETTING BETTER Managers and L&D teams can see who understands, who is stuck, what needs reinforcement, and who is ready to perform — not just who clicked through. LEARN IN THE FLOW OF WORK Fluide is with you on iPhone and iPad, and across Slack and Teams. Ask a question, practise a scenario, or pick up a pathway where you left off. Atlas Copilot users: this is the same app, with a new name. Update to keep learning. Visit fluide.ai to learn more or book a demo. Fluide uses OpenAI to process messages, voice recordings, and files you choose to send, so it can generate replies and run voice chat. OpenAI acts as a data processor for these features and does not use that data to train its general models. We do not sell your personal data. AI processing starts only after you give in-app permission.
