Plimm: AI Journal, Voice Diary

Plimm is a private AI journal and voice diary that writes back. Write or speak, and an AI that runs on your phone reads what you wrote and answers it. No account, no cloud AI. Your entries are never sent to Plimm or any AI service, and you can check it: turn on airplane mode and keep journaling. Most journal apps are somewhere to store writing. Plimm is somewhere to be heard by it: a written diary, a voice journal and a companion for self-reflection in one journal app, and all of it works offline. WRITE, SPEAK OR TALK IT THROUGH - Free writing: a calm, distraction-free diary for daily entries, with no prompts to fill in and no scores. - Voice journaling: speak your entry and Plimm transcribes it on the phone. Your recordings are never uploaded. - A companion that answers: vent, think out loud, or talk something through with an AI journal that has actually read your entries. It listens, reflects and asks. Plimm always makes it clear which of the three you are doing. WHAT IT NOTICES - Insights: specific, gentle observations drawn from your own journal, not generic advice. - Patterns: what keeps coming back in your journal across weeks, written in plain sentences instead of charts, streaks or mood scores. - Crisis support: if your writing suggests you may be struggling, Plimm shows real help, with verified crisis lines for the US, UK, Canada, Australia, New Zealand, Ireland, India, Singapore and South Africa, and your local emergency number everywhere else. FOR THE DAYS BETWEEN THERAPY SESSIONS - Bookmark the moments that matter in a conversation, then turn a date range of them into a summary to share with your therapist. - Export your journal entries whenever you like. - A private diary with a lock: fingerprint, face or screen-lock protection. PRIVATE BY DESIGN, NOT BY PROMISE The AI model downloads once, then runs offline on your device. There is no account to create and no Plimm server, so your journal entries are never sent to Plimm or any AI service, never sold, and never used to train anyone's models. Plimm sends anonymous usage data and crash reports so it can be fixed and improved; you can turn usage data off in Settings. Most private diary apps ask you to trust a privacy policy. This one you can test: put the phone in airplane mode and keep writing, talking and reading your insights. NO STREAKS, NO BADGES, NO NAGGING Plimm will not ask you to rate your sadness from 1 to 10, and it will not guilt you for missing a day. There are no streaks to protect and no reminders to dismiss. It waits until you open it. WHO IT IS FOR For the anxious nights between therapy sessions, or for journaling with no therapist at all. For overthinking that needs somewhere to go at 2am, when texting someone is not an option. For anyone who wants an AI journal that answers, without handing their private thoughts to the cloud. WILL IT RUN ON YOUR PHONE The on-device AI needs a 64-bit phone running Android 10 or later with roughly 4 GB of RAM and 1 GB of free storage, plus a one-time 437 MB model download over Wi-Fi. Plimm checks your phone before you start and tells you plainly if it will not run, rather than quietly falling back to a cloud AI. FREE, AND PLIMM PRO Plimm is free to use. Writing is unlimited and stays that way, and the free tier includes one AI conversation a day, 0:30 voice takes, and your latest insight. Plimm Pro lifts the limits: conversations as often as you need, voice takes up to 5:00, and every insight Plimm has found. Monthly or yearly, and the monthly plan starts with a 7 day free trial. There are no ads. You will always know what you are paying for before you subscribe. Plimm is a journal, not therapy. It is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. If you are in crisis, contact your local emergency number.
