You know what you need to do. The hard part is following through. The email you keep avoiding. The project you keep restarting. The thing that’s been “this weekend” for a month. Catalyst is an AI goal planner built for the gap between knowing what matters and actually doing it. Talk it through with Jax, your voice-first AI coach. Sort through competing priorities, choose a manageable next step, and keep your goals and progress in view. WHEN EVERYTHING FEELS IMPORTANT Five things feel urgent. You don’t know where to start. So you reorganize the list, think about it some more, and end the day with the same things still waiting. Jax helps you work through what’s competing for your attention and turn a bigger goal into a next step you can actually take. Less spinning. More moving. WHEN YOU KEEP PUTTING IT OFF You already know the task matters. That doesn’t make starting easy. Bring Jax the thing you’ve been avoiding — the application, the hard email, the project you’ve restarted three times — and work through what’s getting in the way. You don’t need another productivity tip. You need somewhere to start. WHEN THE WEEK CHANGES Monday’s plan can look very different by Thursday. Meetings move. Something takes longer than expected. A new priority appears. Catalyst keeps your goals, projects, saved steps, and progress together in My Plan so you can return to what matters instead of mentally starting over. A COACH WHO REMEMBERS Jax carries relevant context across conversations, helping you revisit goals, commitments, and the things you keep coming back to. Less re-explaining. More continuity. FROM TALKING TO DOING Use Catalyst to: - Find your focus when everything feels important - Work through the task you keep putting off - Break bigger goals into manageable next steps - Think through decisions without waiting for perfect certainty - Keep goals, projects, saved steps, and progress in My Plan - Mark steps complete and reflect on what helped - Set optional check-in reminders - See your next step on your Home Screen with the Catalyst widget - Ask Jax to add a step to your iPhone calendar VOICE FIRST. TEXT WHEN YOU WANT IT. Talk naturally with Jax while making coffee, taking a walk, or sorting through a busy day. No perfect prompt required. Prefer text? Type instead and follow the conversation in the transcript. COACHING THAT FITS YOU Choose supportive, balanced, or direct coaching, with shorter or fuller replies. Jax draws from a curated coaching knowledge library informed by 347 books across productivity, leadership, personal development, finance, health, communication, and behavior change.
