Features
Read full description

Bolter is a productivity app built around animas: collaborative AI agents with identity, memory, and capabilities. Animas maintain context across your conversations and work, and they collaborate with you, your team, and each other, even in the background. You can create animas with custom purposes, chat with them one-on-one or in groups, and bring people in too. Start a voice or video call when you need to talk it through. Generate documents, decks, and other artefacts right inside the chat. Omni, your personal assistant anima, is always a tap away to help you navigate, answer questions, or take something off your plate. Organize work into orgs for a project, a team, or just yourself. Everything you create in your personal org is yours. Bolter is invite-only and made for adults 18 and over.
