We build the language layer for Africa
Translation models, datasets and tooling for African languages, starting with Sango. Every number on this page carries its source, including the ones that do not flatter us.
Translate into Sango
Free, no key, no sign-up. The same model is available for research under an open licence.
What we can prove
Five numbers, each with its source, its method and the date it was read. Click any chip. The full set, with definitions, is on the metrics page.
What we have built
Three things you can check today without talking to us.
MEYNG API
Translation into Sango over a REST endpoint. The demo above is the same API, with no key. Pilot access is free while we tune it.
eNdara on WhatsApp
A Sango learning bot on WhatsApp, live since April 2026. No install, works on any phone.
Published datasets and models
A trilingual Sango vocabulary dataset (CC BY-SA 4.0) and a fine-tuned translation model (CC BY-NC 4.0, research use), both public, both with their evaluations attached.
Open research
Published with the licence of each artifact stated plainly, and the failures documented alongside the wins.
Sango to French translation model
Fine-tuned from NLLB-200. Beats the baseline out of distribution in the Sango to French direction on two independent benchmarks; loses to it in the other direction, which the model card states plainly.
Research use only, CC BY-NC 4.0, inherited from the base model.
Sango vocabulary dataset
Trilingual Sango, French and English entries with per-entry provenance and review status. Entries that cannot be verified are withdrawn, and the audit trail is public.
CC BY-SA 4.0. Commercial use allowed.
sango-nlp toolkit
Tokeniser, stemmer and language detection for Sango, on npm.
MIT.
The public web-mined Sango corpus advertises 588,039 sentence pairs. After removing duplicated targets, verse numbers and speaker labels, 45,451 pairs survive. Our earlier models learned those artefacts and regressed; the cleaning pass and the gate that now blocks such a release are described in the model card.

If you work in government, an NGO or a company that needs an African language in a product, tell us what you are building. Pilots are free while the API is in pilot.
