Stack Productivity

Features
Read full description

Stack is a modern thought organizer designed to help you capture ideas the moment they strike β€” and bring order to the chaos later. It’s more than notes or to-dos. It’s the first step to shaping your reality. A tool for taking thoughts from the immaterial world and placing it into the physical one. - Jot things down, instantly Whether it’s a reminder, principles, reflections, tasks, ideas, or random thoughts β€” drop a thread of thought into stack. Add just a title or expand with detail when you're ready. - Sort your mind, your way Group your Threads into Stacks (like notebooks), and break those into Branches (like sections or topics). Add Labels and colours to organise how you think, not how software wants you to. - Designed for clarity With a clean, intuitive interface and thoughtful visual design, Stack helps you focus on what matters. No clutter. No pressure. Just space to think clearly and act intentionally. - Real use, real life Use Stack to: Plan life Track personal projects and creative ideas Keep a journal of thoughts and reflections Break down goals or routines Collect inspirations, quotes, or daily reminders Whether you're meal-planning or mind-mapping, Stack adapts to your life. - Make it yours Choose from light and dark themes (More coming soon). Pick fonts that suit your vibe. It’s your mental workspace. - What’s coming soon We’re building AI features to help break down your bigger thoughts into smaller actions, detect urgency, and help you stay on track β€” all without taking control away from you. We're designing and developing more tools to help you process and shape reality, we'll Stack them on when the time comes!

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.
