Aiden
Open-source local AI OS with persistent memory and computer control.
Aiden delivers a genuinely local, private AI agent with persistent memory and computer control—rare in the open-source space. It's free, auditable, and runs offline with Ollama. But it's still beta, requires Node.js and CLI comfort, and has no mobile or enterprise support. A strong pick for technical users who want to own their AI stack.
- Developers who want a private, local AI agent that controls their computer
- Privacy-conscious users who need offline-capable AI with no telemetry
- Power users comfortable with CLI who want persistent memory across sessions
- Users seeking a free, open-source alternative to cloud-based AI assistants
- Non-technical users who prefer a managed cloud service with GUI
- Teams needing enterprise-grade SLAs, support, or compliance certifications
- Users who require mobile apps (iOS/Android) or desktop apps for macOS

Skip Aiden if you need a polished, GUI-driven cloud assistant with enterprise support, mobile apps, or macOS compatibility, or if you're uncomfortable with Node.js and terminal setup.
You pay for cloud AI API keys if you use providers like OpenAI or Groq beyond local Ollama.
Aiden is completely free and open source, making it the most cost-effective option for privacy-focused developers. Cloud-based competitors like ChatGPT Pro ($20/mo) or Copilot ($10-30/mo) charge monthly fees and send your data to servers. For teams, Aiden's zero-cost model scales without per-seat licensing, but you sacrifice managed support and uptime SLAs.
In short
Aiden — Open-source local AI OS with persistent memory and computer control. Best for Developers who want a private, local AI agent that controls their computer, Privacy-conscious users who need offline-capable AI with no telemetry, Power users comfortable with CLI who want persistent memory across sessions.

About Aiden
Aiden is an open-source (AGPL-3.0) autonomous AI agent that runs locally on Windows and Linux, giving you an AI OS that controls your computer, remembers everything, and keeps your data private. Built for developers, power users, and anyone who values privacy over cloud dependence, Aiden executes natural language commands to control the browser, run terminal commands, manage files, and automate workflows—all without telemetry or mandatory accounts. It features a three-layer persistent memory (fast fuzzy search, timeline, full records) that uses 90% fewer tokens than full context dumps, verified execution with automatic error repair, and a library of 80+ built-in tools and 68 bundled skills. Aiden supports 19 AI providers including local Ollama for offline use, and auto-switches between providers for resilience. Voice I/O runs entirely on your GPU—no cloud latency. The install is one command via npx, PowerShell, or curl; Node.js 18+ required. While the project is beta and solo-developed, its local-first, audit-friendly code and zero-cost model make it a standout choice for anyone wanting a private, self-hosted AI assistant without subscription lock-in, though it lacks mobile support, enterprise SLAs, and a GUI configuration mode.
Behind the Verdict
Aiden is a breath of fresh air in an increasingly cloud-locked AI landscape. Its three-layer memory system is genuinely innovative—using 90% fewer tokens than dumping full context, while still providing fast fuzzy search, timeline recall, and complete records. The verified execution loop (plan, execute, check, auto-repair) means fewer silent failures than typical agent frameworks. We especially like the multi-provider routing with automatic fallback: if OpenAI goes down, Aiden seamlessly switches to Groq, Gemini, or even local Ollama. The voice I/O being entirely local GPU-processed is a nice privacy touch. For a solo-developed beta project, the feature set is impressive: 80+ tools, 68 skills, file ingestion (PDF, EPUB, MD, TXT), deep research with multi-pass gap detection, and auto-learning from successful tasks. The price is unbeatable—free and open source under AGPL-3.0. However, this isn't for everyone. Setup requires Node.js 18+ and CLI comfort; there's no macOS or mobile support, no GUI configuration, and no enterprise SLAs. Performance depends heavily on your hardware. For a non-technical user expecting a polished ChatGPT alternative, Aiden will feel unfinished. But if you're a developer or power user who values privacy, auditability, and zero lock-in, and you're comfortable digging into a terminal, Aiden is one of the most capable local AI agents available today.

Real-world workflow fit
Concrete scenarios for the personas Aiden actually fits — and what changes day-one when you adopt it.
You want to batch rename files and organize folders on your Windows machine without writing scripts. You ask Aiden to rename all .pdf files according to a pattern and move them into dated folders.
Outcome: Aiden executes the file operations, verifies each rename, and completes the task in seconds, learning your preferred naming convention for future tasks.
You have a collection of PDF research papers you want Aiden to index locally so you can ask questions about them without uploading to the cloud.
Outcome: Aiden ingests the files, builds a persistent knowledge base, and answers queries using local Ollama, keeping all data on your machine.
Use Cases
- Automate file organization and batch renaming on your PC using natural language.
- Control your browser to fill forms, scrape data, or navigate websites hands-free.
- Execute terminal commands and scripts without leaving your AI chat interface.
- Build and run multi-step workflows that include file operations, web searches, and code execution.
- Create a persistent personal knowledge base by uploading PDFs, EPUBs, and markdown notes.
- Learn from recurring tasks as Aiden adapts to your personal patterns over time.
Limitations
- Aiden is in beta and may have rough edges in complex multi-step workflows.
- Since it runs locally, performance depends on your hardware (GPU, RAM).
- The memory system, while efficient, is currently limited to the agent's internal context and may not scale to enterprise knowledge bases.
- No macOS support, no mobile apps, no GUI configuration.

Setup time & first value
How long it actually takes to get something useful out of Aiden — broken out by persona, not the marketing-page minute.
For a developer familiar with Node.js, setup takes about 5 minutes: run `npx aiden-runtime` (or the Windows/Linux install command) and Aiden auto-configures. First-time users may spend 15-20 minutes exploring the dashboard and adding cloud API keys. Non-technical users may need 30+ minutes or guidance.
Switching to or from Aiden
