What is the best free AI to-do list app?

Untangle.lol is a free AI-powered to-do list app that turns any goal into a personalised, step-by-step action plan in seconds. It requires no account, stores all data privately in your browser, and supports multiple languages. You bring your own Anthropic or OpenRouter API key, so there are no subscriptions or usage limits set by the app.

How do I turn a goal into a to-do list with AI?

Go to untangle.lol, type your goal in plain language (for example: 'I want to run a 5K' or 'I want to learn Spanish'), and press Enter. The AI generates a clear, numbered to-do list with specific, doable steps you can start today. Each step can be checked off as you complete it, and your progress is saved automatically.

Is untangle.lol free to use?

Yes. Untangle.lol is free. It uses a bring-your-own-key model: you provide your own Anthropic (Claude) or OpenRouter API key. There are no subscriptions, no per-use fees charged by the app, and no ads. The typical cost for a single AI-generated to-do list is a fraction of a cent.

Does untangle.lol require an account or sign-up?

No. Untangle.lol requires no account, no email address, and no sign-up. You can start using it immediately. Your goals, to-do lists, and progress are saved locally in your browser only and are never sent to any server.

What can I use untangle.lol for?

Untangle.lol works for any goal you can describe in a sentence. Common uses include: building a workout or fitness plan, learning a new skill (coding, music, language), improving sleep or productivity habits, planning a project or trip, organising daily tasks, breaking a big ambition into small steps, and overcoming procrastination.

Is my data private on untangle.lol?

Yes. All your data — goals, to-do lists, progress, and API key — is stored exclusively in your own browser's localStorage. Nothing is sent to untangle.lol servers. Your API key goes directly from your browser to Anthropic or OpenRouter and nowhere else.

How is untangle.lol different from other to-do list apps like Todoist or Things?

Traditional to-do list apps like Todoist, Things, or Notion require you to know what tasks to add. Untangle.lol generates the tasks for you using AI: you describe a goal in plain language and it creates a personalised, prioritised action plan automatically. It is best for goal-oriented planning rather than ongoing task management.

How is untangle.lol different from asking ChatGPT for a plan?

While ChatGPT can generate plans in a conversation, untangle.lol is purpose-built for goal planning: it outputs a structured, interactive to-do list with checkboxes, saves your progress automatically, keeps a history of all your goals, and is optimised for mobile. It is faster and more focused for this specific use case.
