Tolan

Tolan is an AI companion app developed by Portola, offering an alien character that listens and responds through voice. Its public materials describe a guide for everyday reflection, exploration, and problem solving. The team combines engineering, research, writing, and creative disciplines, with a base in San Francisco and colleagues elsewhere.

In the supplied conference recording, Paula Dozsa discusses engineering Tolan’s iOS experience. She describes how a roughly half-second increase in response time hurt product metrics and prompted user complaints. Her account emphasizes measuring individual pipeline stages and improving turn detection to avoid cutting people off prematurely.

The recording also outlines routing conversations according to emotional stakes, maintaining memory through retrieval and nightly consolidation, and rebuilding context for each turn as subjects change. These practices illustrate Tolan’s approach to conversational responsiveness. Reported conversation totals differ between the homepage and recording, and the supplied funding coverage does not establish a new 2026 round.
