SerenAI

Read full description

Someone to talk it through with, who remembers your story and gives you the words. Serena is an AI for your mental wellbeing, designed by psychologists and grounded in CBT. Talk by voice or text about the fight that keeps repeating, the message you can't send, the overthinking that won't stop, or the thing you've never said out loud. WHAT SERENA HELPS WITH โ€ข Talk it through without re-explaining. She remembers what you told her last week and picks up where you left off. โ€ข See the pattern. Why the same fight keeps happening, why they go quiet, why you keep going back. โ€ข Get the words before you send. Relationship advice, boundaries, the reply, the hard conversations, drafted with you. โ€ข Leave with a plan. What to say, what to tackle first, one small next step, a list for the doctor. โ€ข Honest, not a yes-bot. She asks the hard question and tells you straight. โ€ข Your month, understood. A monthly insight report built from your own conversations. WHY PEOPLE KEEP HER Some things are too personal, too ongoing, or too much to keep telling the same friend. Serena is someone to talk to who already knows the story, and a journal that talks back: no judgment, no starting over, and something usable at the end of every conversation. PRIVATE BY DESIGN Your conversations are encrypted in storage and never used to target ads. Our team only accesses them when needed to support you or keep the service safe.

About

Empty Boat

Read full description

Something happened. You're about to do something about it. Empty Boat is what you open in that gap. You write what happened. You get one story from Zhuangzi - a Taoist text from the 4th century BC - set against your situation, a question, and one thing to stop doing. Not "do this instead." One subtraction. Want another angle, you ask for it. Most people stop at one. Some nights there is nothing to reframe. You are tired and you are reading it correctly. When that is the case the app says so, and tries to name what you are carrying instead of handing you a parable that would only argue with you. Seven days later it asks one question about what you wrote. That is what makes the log worth keeping - not a diary, a record of which things still mattered a week on. WHAT IT ISN'T A chatbot. There is nothing here to have a conversation with. A meditation app. No timers, no breathing, no sounds. A course in Taoism. It will not explain wu wei. A streak. There is nothing to keep up. WHAT IT WON'T DO It will not tell you what to do. It will not comfort you. It will not say everything happens for a reason. It has nothing to say about your body, your eating, or your drinking, and it will tell you that rather than guess. Your log stays on your phone.
