Questions? Answers.
Is my data private?
Yes. Your plans are private by default. We don't train on your data. Shared links are unlisted—only people with the link can see them.
What AI models do you use?
We use OpenAI's latest models (GPT-4 class) for plan generation. The AI prompts we generate work with any LLM—ChatGPT, Claude, Gemini, or local models.
Can I use Decomposer for work projects?
Absolutely. Many users plan product launches, research projects, and team initiatives. Plans can be shared with teammates via link.
What if my plan needs changes?
Every plan is fully editable. Change tasks, reorder steps, adjust labels, or regenerate sections. It's your plan—make it work for you.
How is this different from a to-do app?
To-do apps help you track tasks you've already defined. Decomposer helps you figure out what those tasks should be—with dependencies, honest labeling, and AI-ready prompts.
Ready to think in steps?
Stop drowning in paragraphs. Start executing with structure.
