Hillnote vs Knownbase

Hillnote is a writing tool that thinks alongside you, rich editing, document linking, and AI working right beside you as you write. Local, private, and yours to keep.

Stop re-explaining your codebase to AI. Knownbase gives Claude Code, Codex and MCP agents persistent project memory that survives every session.

About Hillnote

Hillnote is a writing tool that thinks alongside you, rich editing, document linking, and AI working right beside you as you write. Local, private, and yours to keep. Hillnote is where you craft your thoughts in notes, drawings, databases and plans, powered by AI that runs on your device (even when you're offline). No rented database, no lock-in, your work stays yours, even without us. Claude Code, Cowork, Codex, and other agents read, edit, and act on the same files you do, directly, no exports.

About Knownbase

Stop re-explaining your codebase to AI. Knownbase gives Claude Code, Codex and MCP agents persistent project memory that survives every session. Knownbase gives your AI coding agents persistent, searchable project knowledge, so architecture decisions, debugging discoveries, conventions and lessons survive across sessions and tools. Works with Claude Code, Codex, Cursor, ChatGPT and any MCP-compatible agent. They're storage failures: the agent learned something real and had nowhere durable to put it. Compaction loses the discoveries The context gets compacted mid-task and the hard-won finding from two hours ago is summarized down to nothing.
