About these scores

OSS scale score is an unbounded metric that log-compresses and weights Stars, Watchers, Forks, and Contributors. Discovery score is the current OSS scale score minus the score at discovery. Update pace is commits in the last 30 days, growth momentum is the OSS scale score difference within the recent observation window, and OSS health is a 0–100 rating based on available recency, Community Health, and release data.

Overview

Leon is an open-source personal AI assistant built around tools, context, memory, and skills, with smart/controlled/agent execution modes, local and remote models, computer use, and voice/audio capabilities.

Features and best fit

Based on official documentation; not hands-on tested · Content checked:

Switch between controlled and agentic execution depending on the task

Deterministic native skills and step-by-step agent execution coexist, while smart mode chooses a path based on the task.

Sources: [2][3]

Unify memory, skills, computer use, and voice in one assistant

Layered memory, skills, desktop/browser operations, and voice/audio tooling are combined toward a long-lived personal assistant.

Sources: [2][3]

For experimenting with personal agents grounded in local machine context and tools

It fits developers who need more than a chat UI and want model reasoning connected to real environment context and actions.

Do not confuse the 2.0 Developer Preview with the legacy branch

The repository says the develop branch and in-repo architecture documents are the current source of truth while public documentation catches up.

Supplemental curator note

Leon is undergoing a major transition from its earlier intent-classification assistant into an agentic 2.0 architecture. The README dated March 29, 2026 says `develop` is the 2.0 Developer Preview, `master` is the more stable legacy version, and public docs still largely reflect the older architecture. Branch choice matters for evaluation.
