Best alternatives to PAPI in 2026

AI coding tools are powerful within a single conversation, but they don't naturally remember decisions made in an earlier session, which leads to "scope drift" — the AI quietly reinventing choices you already settled, or losing track of what you actually asked for. PAPI plugs into AI coding tools (Claude, ChatGPT, Cursor, Lovable, Bolt, Replit) via MCP to hold that persistent project memory: decisions, plans, and progress, all in one place the AI can reference. It maintains a decision registry that tracks when and why a choice was superseded, measures effort and scope accuracy over time, triggers strategy reviews every five work cycles, supports a shared backlog across multiple people building with AI tools, keeps an audit trail of all changes, and is designed to add no extra AI token overhead since it works inside the tools you already use rather than replacing them.
