💡 Knowledge & Insights

• P.A.R.A-based knowledge organization (Projects, Areas, Resources, Archives)
• Insight cards that surface connections across records:
  • Charts (trend, bar, radar, bubble, composition, progress ring) — visualize patterns, distributions and goal progress over time
  • Narrative (highlight, contrast, summary) — surface key conclusions, before/after comparisons, and periodic reviews
  • Spatial & temporal (map, route, timeline) — reconstruct where and when things happened
  • Gallery — visual memory from your photos

📝 Pure Text & Data Freedom

• Effortless Archiving: After AI organization, all your records naturally settle into a series of interconnected Markdown files, making one-click diary and document archiving a breeze.
• Evolve Alongside AI: Why Markdown? Because as AI capabilities rapidly advance, only the purest text records can bridge the gap of time and truly keep pace with its evolution. As LLM models strengthen, these simple records will reliably unlock entirely new interactive experiences and profound insights for you in the future.
• Absolute Freedom to Leave: Zero vendor lock-in. If you ever feel our product no longer meets your expectations, you can one-click export all your records as standard Markdown files and migrate seamlessly to any note-taking app at zero cost.

🔒 Privacy & Local-First

• All data stored locally (filesystem + SQLite)
• App lock with biometric authentication
• No cloud dependency — your data never leaves your device

📂 Storage & Backup

• Supports iCloud Drive, Device storage (custom folder) and App storage
• One-tap full backup / restore

Configure LLM

Memex requires an LLM API key to power its AI features. On first launch:

1. Tap the avatar icon → Model Configuration
2. Select your provider (Gemini / OpenAI / Claude / etc.)
3. Enter your API key and base URL
4. Each agent can be configured with a different model independently

🧩 Custom Agent System

Memex isn't just a recording app — it's a platform that lets you build your own AI agents on your phone.

Every built-in agent in Memex (knowledge extraction, card generation, insight discovery…) runs on the same custom agent infrastructure, and that infrastructure is fully open to you. That means you can create agents with the same capabilities as the built-in ones.

What You Can Build

• 🎯 Create agents freely — Give it a name, pick a host type (Pure mode), and a new agent is ready to go.
• ⚡ Event-driven triggers — Choose when your agent activates: on user input, after knowledge extraction, on card creation, on insight generation, or any system event.
• 🧠 Per-agent LLM configuration — Each agent can use a different model.
• 📝 Custom system prompts — Shape your agent's personality, expertise, and output format with a custom system prompt.
• 📂 Skill — Memex adopts the open Agent Skills standard. Each agent reads its behavior from a SKILL.md file — a folder of instructions, scripts, and resources that agents discover and use on demand.
• 🗂️ Working directory — Each agent can be configured with its own workspace. File reads, writes, and listings are scoped to that directory.
• 🚀 JavaScript execution — Skills can run JavaScript code, including fetch() for HTTP requests. Call external APIs, transform data, scrape web content — all running locally on your device.
• 🔗 Inter-agent dependency chains — Define execution order with dependsOn to build complex workflows. Agent B waits for Agent A to finish before it starts.
• 🔄 Sync & async execution modes — Run agents synchronously (inline, blocking) or asynchronously (queued as background tasks) depending on your workflow needs.
• 🔁 Auto-retry with configurable limits — Async agents automatically retry on failure, with a configurable max retry count.

How It Works

System Event (user input, card created, insight generated, ...)
    ↓
Event Bus dispatches to subscribed agents
    ↓
Agent loads SKILL.md + system prompt
    ↓
LLM processes the event with available tools
    ↓
Agent executes actions (file I/O, JavaScript, fetch, ...)
    ↓
Continues to downstream dependent agents and presents results to the user

Every agent you create is a first-class citizen — it plugs into the same event bus, uses the same tool system, and has the same capabilities as the built-in agents. The only limit is your imagination.
