What is Sequo?
Sequo is a planning and documentation service for AI-assisted development with Claude Code or Codex. It transforms a project idea into an ordered development plan plus eight living documents, then generates one copy-ready prompt per step that explicitly names the documents the agent must read, preventing context loss across sessions.

Frequently asked questions about Sequo
How is Sequo different from just using a CLAUDE.md file?
Sequo automatically writes and updates documentation as you go and names specific files in every prompt, forcing agents to read them. Single files work early but get skipped as projects grow; Sequo prevents this by enforcing document references.
What if I make a mistake or want to change a step?
You can rewrite any step's prompt, a single document, or the entire plan without losing access to what you've already built. Everything stays yours.
Do I need to pay to start?
No—you describe your idea and answer clarifying questions before creating an account. Your idea stays private and is deleted on request.
