Manifold

The macOS app for non-code work with Claude and Codex. You pick what each AI sees. File by file, message by message, or with rules across folders and mailboxes. Version history, audit log, and on-device PII redaction via OpenAI's Privacy Filter. Your contextual file history lives on your Mac, reusable across any new chat even with a different AI tomorrow.
