Personal Intuition: Associative Cross-Thread Memory

Personal Intuition is associative memory across every conversation you've ever had. Caiioo remembers things you've discussed, and as you chat, relevant memories surface automatically. It's like having a continuity of thought across all your threads.

How It Works

As you type a message, Caiioo searches your conversation history for related topics. If a past discussion is relevant, it surfaces in the message composer so you can include it, or the AI factors it in automatically. No manual prompting needed—it just happens.

Example: If you discussed a marketing campaign in one thread and now you're brainstorming in another, Personal Intuition remembers the earlier context and the AI can weave it together.

Turning It On

Off by default. Here's how to enable it:

Go to Settings > Personalization & Privacy > Personalization
Click Enable Personal Intuition
Choose Full Rebuild (one-time indexing of all past threads) or Incremental Backfill (faster, catches up after a gap)

Full Rebuild takes longer on first run but ensures every thread is indexed. Incremental Backfill is faster but only picks up new conversations since you last indexed.

How Indexing Works

Embeddings run on-device. Caiioo uses a small multilingual-e5 model to encode your conversations locally. On iOS, this runs natively via onnxruntime-objc. Embeddings are cached in memory (~10ms per query vs ~5s cold start). The same on-device e5 pipeline powers Instant Tool Chooser (the ~10ms AI tool selector available on every tier, including Free), so the cold-start cost is paid once.

All the reading and indexing happens locally — no conversation content is sent anywhere to build your memory. If you use Private Sync, the finished memory syncs between your devices the same way your conversations do: encrypted before it leaves, readable only with your passphrase.

Check Indexing Status

In Settings > Personalization & Privacy > Personalization, you'll see a live Personal Intuition status:

Indexed: 142 threads · 3,847 chunks · 18,234 tokens · last indexed 2m ago

During backfill, it shows progress:

Backfill in progress: 47 / 75 threads · 2,134 chunks

So it never looks stuck—you can watch it work in real time. When backfill completes, the last summary stays visible so you know you're caught up.

Your Memory Travels With You

With Private Sync on, what Caiioo remembers syncs between your devices along with everything else. A new phone or laptop arrives with its memory ready to use — it doesn't have to re-read your whole conversation history before recall starts working.

Deleting works across devices too: remove a conversation on one device and what was remembered from it is removed everywhere, so a deleted conversation can't keep answering for you somewhere else.

Backup & Restore

Prefer a snapshot you control, or want to move memory between devices without Private Sync? Go to Settings > Data & Sync > Backup & Restore > Personal Intuition:

Click Backup to download your full memory corpus as JSON
On another device, click Restore and select the file

Use this to migrate between devices or archive your memory history.
