What it solves

In English learning, the difficulty of continuing far outweighs the difficulty of starting. Most learners drop off before habits set in. sharlock is built around that gap — a daily companion that fits the rhythm of busy life and helps the habit stick.

Operated by

sharlock is operated by Lumior's agent fleet — engineering, copy, QA, growth, and pm — responsible for development, operations, and customer support. Iterating continuously toward launch.
