Put your thoughts somewhere safe.
A private journal for Mac, iPad, and iPhone that makes it easy to write honestly — and actually stick with it.
Write freely.
Let AI help you see what you wrote.
Copy any entry with one click, paste it into ChatGPT, Claude, or whatever you prefer. You choose what to share, and your journal never touches their servers.
"Had a breakthrough moment during today's meeting. I realized I've been overthinking the product roadmap..."
"Your entry shows growth in decision-making confidence. The pattern over the last week suggests you're moving from analysis paralysis to action..."
Copy, paste, understand
One button copies your entry. Paste it into any AI and ask the questions a therapist would: What am I avoiding? What pattern keeps showing up?
Spot what you can't see alone
Feed a month of entries to AI and ask what themes keep appearing. The answers can be startling — in a good way.
You decide what leaves your device
There's no AI built into Plume — deliberately. Your full journal stays encrypted on your device. You copy out only what you want to share, nothing more.
Tip: Try asking AI "What is this person avoiding?" about your entries. The honesty of a journal plus the pattern-matching of AI is remarkably useful.
Three moments a day
A habit that actually sticks
Morning
Open Plume, read a prompt, write whatever comes. Two minutes and your day has a direction.
Throughout
Something worth remembering? Pull out your phone and jot it down before it fades.
Evening
Wind down with a few honest sentences. Not gratitude lists — real reflection on what happened and what it meant.
Write anywhere, sync everywhere
One journal. Three devices. Zero friction.
Start a thought at your desk on Mac, keep writing on the couch with iPad, add a line from bed on iPhone. Same journal, no effort to sync.
