Castalia is a journal for people who think in circles, forget what they figured out last month, and want one place that holds all of it. Write it or say it. Find it later. (Formerly InkWell.) ONE QUESTION TO START Each day opens with a single question and a blank page. Nothing here needs to be good. It just needs to be true. WRITE IT, OR SAY IT Type, or tap the mic and your words land on the page. Want a push? Start the timer for a timed write. THREE WAYS IN • Free-write: the page, with your voice and a timer when you want one. • Gratitude: three short practices from gratitude research, one suggested each day. • Reframe: four steps to look at a hard moment from a second angle. SOPHY, WHEN YOU ASK Sophy is Castalia's AI companion. She offers a prompt when you want one and a reflection after you write. She reads your journal only when you ask, or when you turn on her insight emails. FIND WHAT YOU WROTE Ask your recent entries in plain words, like "when did I last feel rested?", or open the calendar to any day. Search is free. GOALS WITH A PLAN Name what you want, picture it, plan for the snag that usually stops you, and let Sophy check the plan. Not sure what you want yet? Start from your values. Finished goals stay in your journal. NOTICE WHAT WRITING DOES If you like, rate how heavy a day feels before and after you write. PRIVATE BY DESIGN Your entries are encrypted in transit and at rest, never sold, and never used to train AI. Export all your entries and goals, any time. FREE, AND PLUS The full journal is free: every way to write, voice, search, goals and a daily reminder. Castalia Plus adds Sophy without a daily limit, a monthly read of your writing, cleaned-up voice entries, photos and files, and weekly and monthly insight emails if you turn them on. $6.99 a month or $49.99 a year. Castalia is a coaching tool. It is not used for diagnosis or therapy.

As an early Generation Z born In the early 2000s this app has been very useful to me to reflect my gratitude about me and to everyone. ## Frequently asked questions about Castalia ### What are the different subscription tiers for InkWell?
