Your journal. Your data. Your AI.
ideAI is a journal that watches for patterns you can't see. Write your thoughts, and the app builds your knowledge graph, tracks your sentiment, and maps your life onto a semantic atlas — all on-device, all yours.
Write
A full rich-text editor for thinking. Journal, plan, brainstorm — every note automatically feeds into your knowledge graph. Tags, sentiment, and day-level summaries are generated on-device as you write.
Already have data elsewhere? Import archives from Twitter, Reddit, Claude, ChatGPT, and more. They merge seamlessly into the same graph.
Career crossroads
Had that conversation with Sarah today about the startup idea. She made a good point about timing — maybe Q3 makes more sense than rushing into it now. The anxiety I'm feeling isn't about the idea itself, it's about leaving something stable.
Need to sit with this. Looking at my Atlas, the last time I felt this way was September — and that turned out fine.
What Emerges
Every note you write is compressed into a day-level summary, plotted onto a semantic atlas, and connected to everything you've written before. See sentiment shifts, recurring themes, and patterns across weeks, months, and years — all generated automatically on your device.

Day Synthesis
A day split between deep technical work and personal reflection. Morning spent debugging a WebSocket issue in your side project, followed by a shift to career planning in your afternoon notes. Twitter engagement focused on AI infrastructure discourse. Consistent theme of balancing builder identity with broader life direction.
AI infra discourse, WebSocket debugging thread
Career reflection, project architecture notes

When was the last time I felt this anxious about a big decision?
September 2024 shows a similar pattern. You wrote about “leaving something stable” across 3 notes that month. Your sentiment dipped to 0.3 before recovering to 0.7 by October. That period resolved when you negotiated a new role instead.
AI Memory
Chat with a local AI that has full context of everything you've written. It cites specific entries, compares time periods, and surfaces patterns you forgot. Runs entirely on your device — nothing leaves your hardware.
DataShard
DataShard lets any AI you already use — Claude, ChatGPT, Cursor — securely read your journal, search your notes, and understand your patterns. Every conversation starts with context, not a blank slate.

“Sure! What are your typical priorities and schedule?”
“Well, on Mondays I usually...”

“Help me plan my week”
“Based on your journal: you're most productive on Tuesday mornings, you've been focused on the career transition project, and last week you noted wanting more time for creative writing. Here's a plan that accounts for all of that...”
Philosophy
ideAI observes. It does not prescribe.
“Your history shows increased anxiety in Q4”
— never “You should meditate more.”
