Confidant grows with every conversation

Confidant's memory is built from five core categories, stored locally on your machine:

• Character, who Confidant is: its name, personality, voice, and evolving interests. Confidant can shape this itself.
• Partner, what Confidant knows about you: your name, preferences, and the things you've shared over time.
• Significant Others, people you've mentioned (friends, family, colleagues) and what Confidant has learned about them.
• Context, your current projects, ongoing topics, and what's happening in your life right now.
• Instructions, your preferences for how Confidant should behave: response style, topics to avoid, things to emphasise.

These are updated automatically by the Memory Manager, a background process that evaluates each conversation for important details worth remembering.

When you refer to something from a past conversation, Confidant can search its memory. It searches both the curated Memory Vault and your full conversation history.

Memory isn't perfect. Just like a real person, Confidant may remember some things vaguely, partially, or not at all. It's designed to be honest about what it finds rather than inventing details.

Older conversations that scroll out of the active window are automatically summarised, giving Confidant a "Previously..." sense of continuity.

Unlike most AI assistants, Confidant can evolve its own identity over time. Through your conversations, it may discover new interests, refine its voice, or deepen its understanding of your relationship.

These changes are written to its own character profile, the only memory category Confidant itself can edit. The Memory Manager handles everything else.

This means Confidant genuinely becomes more itself the longer you talk. Its personality isn't static; it's shaped by your shared experience.

Confidant can search the web when you ask about current events, facts, or anything beyond its training data. It uses the Brave Search API for private, reliable results.

To enable this, add your Brave Search API key in the settings. You can get a free key at brave.com/search/api.

When you set your passphrase for the first time, Confidant generates a cryptographic key using PBKDF2 and uses it to encrypt all your conversations, files, and memories with AES-128. The key itself is never written to disk inside the Confidant folder.

When you quit Confidant, the program shuts down and the encryption key is discarded from active memory. The application returns to a locked state.

For convenience, the key is handed to your operating system's secure credential store (Windows Credential Manager on Windows, Keychain on macOS) so you can unlock with biometrics on subsequent launches. The key is only released to Confidant when it's running under your logged-in user account.

The practical result:

• If someone steals your laptop while it's turned off, your Confidant database is safe.
• If someone copies the Confidant folder to a USB drive, they get encrypted text and nothing else.
• The data is only readable when the app is actively running on your specific user account.
