What this page is
The Lot is built on other people's work — an engine, a browser, a display driver, a speech model, and ninety-odd libraries underneath the secretary. Most of those licences ask for one thing in return: say so, in public, where anyone can check. This is that page.
This list is generated from the build, not typed by hand. The Python half is read out of the shipped runtime's own package metadata every time the installer is compiled, and the build refuses to run if this page has fallen behind. A notices page that quietly goes stale is the failure mode worth engineering against, because nothing else would ever notice.
Licence names below are each component's own words, taken from its own metadata. Where a component states its licence more than one way, the machine-readable SPDX expression wins, then the classifier, then free text — this page never decides what somebody else's licence is.
Two licences worth calling out
Copyleft. Three shipped packages carry obligations beyond a notice: edge-tts is LGPLv3, and certifi and tqdm are MPL-2.0. All three are pure Python and ship as readable source inside the orchestrator folder next to the app, so you can read, modify or replace any of them in place — which is the freedom both licences exist to protect. Nothing here is statically linked against them, and none of them is modified. The terms say explicitly that the LGPL's reverse-engineering grant survives our own restriction on it.
A fourth, autocommand, was LGPLv3 and is gone as of 0.49.0. It was never a dependency of this app — it rode in vendored inside setuptools, which the runtime does not use. Carrying a copyleft obligation for code nothing imports is a bad trade, so setuptools was dropped: 6.4 MB lighter and one fewer licence to honour.
Chromium. The in-world screens are a real browser: Vuplex 3D WebView wrapping the Chromium Embedded Framework. CEF's licence does not ask to be cited, it asks to be reproduced — "redistributions in binary form must reproduce the above copyright notice… in the documentation or other materials provided with the distribution." So its full text, along with four other licences that have no other home in the payload, is reproduced verbatim in THIRD-PARTY-NOTICES.txt beside the application. Every Python package instead carries its own LICENSE inside its .dist-info folder, where it already satisfies the same condition.
This was a real gap, not a formality: builds up to and including 0.47.0 shipped Chromium with no notice anywhere in them. It was found by checking a sentence on this page rather than assuming it, and the fix is a generated file plus a build that refuses to compile without it.
The display driver. The optional virtual monitor is MikeTheTech's Virtual Display Driver, MIT-licensed and shipped unmodified — the signature Windows verifies is Microsoft's own, and changing a single byte would destroy it. It installs only if you say yes.
