What’s on your mind?

How it works

Just say it.

That’s the whole job. Open MountainRiver and write — or speak — whatever’s there: a moment, a worry, a person, a plan. Ten seconds or ten minutes.

MountainRiver keeps it, reads it quietly, and organizes it for you — into the themes of your life, the people in it, the patterns across time. You never file, tag, or sort a thing.

Everything below grows from that one act.

01 · Understand

See what's really going on.

Write whatever's on your mind — a moment, a person, a worry. The themes of your life emerge on their own: the people, the patterns, what keeps arriving together. Named in your words. You never organize a thing.

Your relationships become clearer: how they’re changing, what they give you, how your feelings move over time.

02 · Decide

Make the right call. MountainRiver has read your whole story.

Bring MountainRiver the decision you keep turning over. Because it knows your actual life, it lays out the shape of the choice: what it's really about, the paths in front of you, and what each would give you and cost you — grounded in what you've lived, with dates. Not the internet.

The map is kept, and re-openable — a decision you can return to until it settles.

03 · Direct

Name the goal. See exactly how to get there.

Set a goal — or a dream — and it charts two or three genuinely different routes toward it, drawn from how you've actually moved before: your own phrases, your own dates, the things you've finished. Not generic advice. Your life, pointed forward.

Choose a way, make its first steps yours, and walk them — waypoint by waypoint, with a climb log that remembers every choice.

Your words are yours.

✓  No human at MountainRiver ever reads your entries — there is no tool that lets us, or anyone, see what you write.

✓  Your writing is stored in the EU and is never sold, shared, or advertised against.

✓  When you ask for AI reflection, your writing is sent to Anthropic’s AI for that one analysis — with no name or account attached — and it is never used to train AI models. Neither do we.

✓  Export or permanently delete everything — your writing and your account — any time. When you delete, it’s gone.

With each passing year, time seems to go faster and faster. How do you notice what’s important? How do you assimilate the lessons that life has taught you? How do you make good decisions that are based on your values — and how do you achieve the goals that matter to you?

These are fascinating questions to me, and part of the reason I’ve been journaling for the last twelve years. MountainRiver is my attempt to use AI to make sense of my human life. I use it every day. It creates value for me — and I hope it will create value for you too.

Welcome to the private beta.
