Email that remembers, without taking over.

Postscript is an AI-native inbox for labels, reply queues, drafts, contact memory, and tone profiles. Every AI action is reviewable, sourced, and reversible.

02Operating Model

Reviewable intelligence, not magic state.

Labels, drafts, tone profiles, contact grouping, and any outside context Postscript pulls in are stored as first-class records with model name, prompt version, input hash, confidence, reason, and user feedback.

Context
Calendar and meeting notes

Drafts pull from your calendar, recent meeting notes, and the tools you connect. Every reference is shown with its source so you can verify or strip it before sending.

Labels
Natural language criteria

Create labels by description, backfill a chosen history window, and keep assignment reasons available for correction.

Drafts
Approval-only generation

The inbox detects likely replies, drafts with tone context, and never sends without explicit approval.

Memory
Contacts and groups

Contacts inherit group defaults, can learn tone from history, and preserve durable relationship notes.
