Your notes are dying
The Graveyard Problem
You capture everything. You find nothing. 90% of your notes are write-once, read-never.
The Tool Sprawl
Notion for docs. Obsidian for notes. Anki for flashcards. Calendar for tasks. Nothing talks to anything.
The Cloud Trap
Your private thoughts live on someone else's server. One subscription cancellation and your brain goes dark.
What if your notes could think?
DayDot is the agentic second brain — a local-first desktop app where AI agents capture, organize, connect, and surface your knowledge autonomously. Your data stays on your machine. Your AI works while you sleep.
Local-First, Always Yours
Your data lives on your machine in plain Markdown. No cloud. No lock-in. Works offline.
AI Agents That Work For You
Background agents tag, link, summarize, and surface relevant notes without you lifting a finger.
Agentic Flashcards
Personalized active recall powered by AI. It doesn't just store what you learn — it makes sure you remember.
One App, Not Ten
Journal, tasks, canvas, knowledge base — organized by the PARA method in one unified workspace.
Built for how you actually think
Agentic Second Brain
AI agents capture, tag, link, and summarize your notes automatically in the background.
Smart Flashcards
Spaced repetition meets AI — flashcards generated from your notes, adapted to your forgetting curve.
Private by Design
All data stored locally in Markdown + SQLite. Zero cloud dependency. Your thoughts are yours alone.
Digital Bullet Journal
Rapid logging, threading, and collections — the bullet journal method, reimagined for the digital age.
Knowledge Graph
Bidirectional links, backlinks, and a force-directed graph that reveals hidden connections in your thinking.
Works Offline
Full AI capabilities without internet. Built on local LLMs via Ollama. Think anywhere, anytime.
From chaos to clarity in 3 steps
Capture Everything
Quick-capture from anywhere. Notes, voice, web clips — all flow into your inbox.
AI Organizes For You
Background agents tag, link, and file your captures. No manual sorting needed.
Think Better, Learn Faster
Chat with your brain. Get smart flashcards. See connections you missed.
Not just a note app. A thinking partner.
Most note-taking apps are digital filing cabinets. DayDot is different.
Imagine AI agents that work like personal librarians — silently organizing your chaos, surfacing forgotten insights exactly when you need them, and challenging your ideas like a Socratic tutor.
Your brain. Your machine. Your rules.
