Credits

Last updated: August 2026

Andromeda is built on work that other people gave away. Some of it is credited here because its licence requires it, and some because it would be poor manners not to — this page does not distinguish between the two.

The full technical record, including licence terms and the models we rejected on licensing grounds, lives in ATTRIBUTION.md in the source tree.

1. Emoji

Emoji artwork is Twemoji, created by Twitter and its contributors and now maintained by the community.

2. Typefaces

The typefaces in the composer’s font picker come from Google Fonts, and remain the copyright of their individual designers. They are released under the SIL Open Font License 1.1, with a few families under the Apache License 2.0.

The full licence text ships alongside the fonts at /fonts/OFL.txt. We subset them by glyph range so that only the characters a page actually uses are downloaded; none is renamed or redesigned.

3. Astronomical imagery

The galaxies, planets and skies you see in Andromeda are not photographs. They are rendered — generated for this product, or drawn in code from real star catalogues and orbital mathematics. The night sky in the Lens is computed from ephemerides; the galaxy you fly through is a made thing.

Andromeda carried a real Hubble photograph of M31 on its landing page for a while. It was removed in August 2026, and nothing here is derived from it.

4. On-device intelligence

The models that run inside your browser — the ones that let the Lens see, read and hear without sending anything anywhere — are open models released by others:

Google — SigLIP2, EfficientDet, MobileNetV3, the AIY nature classifiers, YAMNet, and MediaPipe (Apache 2.0).
OpenAI — Whisper, which transcribes on your device in the Vigil (MIT).
Microsoft — ONNX Runtime Web (MIT), and Tesseract for on-device text reading (Apache 2.0).

5. Knowledge

Species names come from Wikidata (CC0, public domain). Where a species is likely to be found, and when, is derived from occurrence records aggregated by the Global Biodiversity Information Facility — which exists because thousands of museums, herbaria and citizen-science projects publish their records openly. Scene vocabulary draws on the Places365 category names from MIT CSAIL.

6. Open-source software

Andromeda runs on several hundred open-source packages, overwhelmingly under the MIT, Apache 2.0, BSD and ISC licences — including Next.js, React, Prisma, Tailwind CSS and FFmpeg. We are grateful to all of them, and to the people who maintain them largely unpaid.
