Field-grade data collection in the languages your model has never heard.
Native-speaker audio, video, image and text collection across Indic, African and low-resource languages — field-grade, consented, documented.
When the data you need doesn't exist on the open web, we collect it — with native speakers in the field, written consent on every record, and documented provenance you can defend in a procurement review.

The languages and contexts that matter most to your users are exactly the ones missing from scraped corpora. Low-resource Indic and African languages, regional accents, code-mixed speech and domain-specific vocabulary are scarce, noisy or simply absent — and what does exist is rarely rights-cleared enough to train on commercially.
Building it yourself means recruiting native speakers across regions you don't operate in, managing consent and fair pay, and enforcing a quality bar at scale. That's a field operation, not a data download.
Rights-cleared, native-speaker datasets delivered as versioned drops with a data card: written consent on every record, documented provenance and licensing, and published quality metrics. You train on data you can legally use — and prove where it came from.

FAQ
Multilingual Data Collection — common questions
- Is the data rights-cleared and safe to use commercially?
Yes. Every record is created or sourced under written agreements granting commercial reuse, with a consent reference and authorship log attached. We don't ship scraped data you can't legally train on.
- How do you measure and report quality?
We publish quality metrics on every delivery — inter-annotator agreement, QA pass rate, and (for speech) word error rate — with two-pass QA and adjudication. Each drop ships with a data card documenting methodology and provenance.
- Can you guarantee India data residency?
Yes. We offer sovereign delivery: work performed and stored entirely within India, aligned with the DPDP Act, 2023. See our Sovereign Data page for the full residency and compliance posture.
