See how it’s changed you. Ask it anything. Watch the patterns surface.
Start free →You don’t begin from a blank page. Bring years of journals — a lifetime of them, if you have them — and MountainRiver reads every word: the themes of your life, the people in it, the patterns across time. You never file, tag, or sort a thing.
Then, day to day, just say it. Write or speak whatever’s there — a moment, a worry, a person, a plan — and it joins the record, read and remembered alongside everything else.
New to this? A single sentence is enough to begin — it grows with you.
Every theme of your life — money, work, a relationship — read across all the years you've written, in your own words. The people, the patterns, what keeps arriving together. You never organize a thing.
And the arc becomes visible: how something has slowly changed you, across time you could never hold in a single view.
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.
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.
✓ 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.

Everything in Capture, plus the part that reads across it all: ask your journal anything and be answered from your own years of writing. Decisions mapped from your history. Themes and relationships surfaced over time — the patterns you couldn’t see from inside any single year.

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.
