Your thoughts deserve a companion. STASH helps you capture, organize, and revisit ideas with a playful squirrel guide. New users get a personalized walkthrough.
YOUR THOUGHTS DESERVE A COMPANION
STASH is your personal thought companion—an AI-powered journal that captures ideas, questions, and moments worth remembering. But you're not alone in this. You have a squirrel who adapts to how you think, celebrates your consistency, and genuinely wants to see your idea vault grow.
CHOOSE YOUR SQUIRREL'S PERSONALITY
Pick from five distinct companions, each with their own voice:
• Supportive Listener – Warm, validating, always here for you
• Brainstorm Partner – Enthusiastic idea hunter who gets excited about connections
• Socratic Questioner – Thoughtful guide who asks the questions you're avoiding
• Journal Guide – Gentle presence helping you process emotions and experiences
• Devil's Advocate – Sharp challenger who stress-tests your thinking
Your squirrel speaks in their voice throughout the app—in notifications, celebrations, and gentle nudges.
CAPTURE EVERYTHING THAT MATTERS
The fastest capture experience on iOS. Open the app, type or speak, done. Your thought is saved, classified, and enriched with context—location, time, calendar events, even your energy level if you grant HealthKit access.
No folders to pick. No tags to remember. STASH uses on-device AI to understand what you captured and organize it automatically. Reminder? It knows. Idea? Tagged. Random observation? Filed away for later.
EARN ACORNS, BUILD STREAKS
Gamification that actually works. Every thought you capture earns acorns. Capture daily, build a streak. Hit milestones, earn bonuses. Your squirrel celebrates with you.
Acorns unlock accessories for your companion in the Acorn Shop. Streaks give you momentum. Badges recognize your consistency. It's addictive in the best way—because the habit you're building is valuable.
YOUR THOUGHTS GET SMARTER OVER TIME
STASH learns from you without sending your data anywhere. On-device machine learning means:
• Auto-classification improves the more you use it
• Similar thought detection helps you spot patterns
• Semantic search finds connections you didn't see
• Smart insights surface your most valuable captures
Everything stays local. Your thoughts never leave your device unless you explicitly export them.
CONTEXT MAKES THOUGHTS RICHER
Grant optional permissions and STASH remembers where you were when inspiration struck, what was on your calendar when you had that realization, and how you were feeling physically. Context makes thoughts more than text—it makes them moments you can revisit with full clarity.
NOTIFICATIONS THAT DON'T ANNOY
Your squirrel can reach out—but only if you want, and only in ways that help:
• Daily Nudge – Timed to when you usually capture (learned from your behavior)
• Streak Celebrations – Morning recognition when you hit milestones
• Gentle Check-in – Soft reminder after 2 days without capturing
• Shiny Alerts – When the app identifies a particularly valuable thought
Fully customizable. Persona-voiced. Actually useful.
DESIGNED FOR PRIVACY
STASH is local-first by design:
• All data stored on-device with Core Data
• Classification runs on-device with Apple's NaturalLanguage framework
• No cloud sync in this version (your data stays yours)
• No ads, no tracking, no third-party analytics
• Export anytime as JSON or plain text
WHO IS STASH FOR?
Thinkers who have too many ideas and nowhere to put them. Journal keepers who want structure without rigidity. People building a second brain or personal knowledge base. Anyone tired of notes apps that feel like filing cabinets. Folks who want their productivity tools to have personality.
START WITH A GUIDED WALKTHROUGH
New users get an interactive tutorial led by their chosen squirrel. No feature carousels—just real interaction. You'll capture your first thought, earn your first acorn, understand streaks, and set up permissions. By the end, you know exactly what STASH does because you've already done it.
Download STASH and meet your companion.
