One engine under your coding agents

LECTERN

Lectern wraps Claude Code, Antigravity, and OpenCode — on your desktop and in your terminal. It plans each task, routes it to the model that's best at it, and shares one brain and one session history across every surface. Local-first, Linux-first, free & open source.

The difference

A model answers. An engine orchestrates, remembers, and stays yours.

01 / Orchestration
Many models, one task

The Conductor plans your task and hands each part to the model best at it — Opus for the hard reasoning, Gemini Flash for the fast work — running independent steps in parallel across git worktrees and cross-reviewing the code between providers.

02 / Memory
A persistent brain

Memory, a learned machine profile, your recorded skills, and a graph of your codebase — fed into every session so agents start knowing your repo instead of re-exploring it. Recall stays lean: only the files that actually match, and only the relevant slice of each, so context never balloons your token bill.

03 / Local-first
Runs on your machine

Every session executes locally and your keys never leave — the cloud only ever sees counts and ciphertext. Linux-first down to real desktop control, with Windows and macOS builds rolling off public CI.

The platform

One engine. Every surface you work from.

Everything below ships today — the same local engine and the same persistent brain, whether you drive it from a window, a terminal, or a service.

Desktop App

The cockpit. Chat, plans, diffs, terminal, the brain graph — plus a personal agent with schedules and a Telegram channel, so runs reach your phone.

TUI + CLI + lecternd

The engine in your terminal: lectern tui (sessions, streaming, models, /conduct), the scriptable CLI, and the daemon — same brain everywhere.

No new subscription. Point Lectern at Claude Code or Antigravity — it routes each task to the model that's best at it, and your memory and skills follow across both.
