Contact Models

Contact Models are the foundation of Outband’s intelligence. They are per-contact AI profiles that capture how each person communicates.

​

What a Contact Model Contains

Each Contact Model captures multiple dimensions of a person’s communication:

​

How Contact Models Are Built

Contact Models build automatically from your communication history:

1. Initial build — When you first connect email, Outband analyzes 6-24 months of history and creates models for your top 50 contacts within the first hour
2. Continuous refinement — Every new message you send or receive updates the relevant Contact Model
3. Cross-channel enrichment — If you connect Slack or WhatsApp, messages from those channels enrich the same Contact Model
4. User corrections — When you correct Outband’s understanding, the model updates immediately

​

Bilateral Intelligence

Traditional AI tools only model one side of a conversation — you. Outband models both sides:

• Your Personal DNA captures how you communicate
• Contact Models capture how each contact communicates
• Together they enable Perception Prediction — predicting how a specific person will interpret a specific message from you

This bilateral approach is what enables the “Tanaka-san moment”: knowing not just what to say, but how it will be received.

​

Confidence Scoring

Every Contact Model has a confidence score based on four factors: The confidence score is visible on every Contact Model and on briefing items. It helps you gauge how much to rely on Outband’s analysis for a given contact.

​

Personal DNA

Your Personal DNA is the Contact Model that represents you. It captures:

• Your writing style and vocabulary
• Your tone preferences across different contexts
• Your typical response patterns
• Your communication priorities

Personal DNA is what makes AI drafts sound like you, not like a generic AI.

​

The RLHF Feedback Loop

Every interaction with Outband improves your Contact Models:

1. Outband generates a draft or makes a prediction
2. You review and either approve, edit, or reject
3. Your feedback is fed back into the model
4. Future interactions with that contact become more accurate

This creates a virtuous cycle: the more you use Outband, the better it gets, which makes you use it more, which makes it even better.

​

Privacy

Contact Models are built from your private communication data. Important privacy facts:

• Contact Models are not shared with the contacts themselves
• Non-consenting contacts (people who are not Outband users) have models built under legitimate interest, with no personally identifiable information stored in model weights
• Any contact can request a data subject access report or deletion of their model
• Your Contact Models are fully exportable and deletable at any time
