Methodology
Our comparisons focus on how data is supplied, which rights a seller needs and what a licensing counterparty must clarify. A service that produces labels is not the same as a channel for licensing an archive.
How to read our comparisons
- Start with the supply model: existing-data licensing, annotation, expert production or evaluation.
- Distinguish a company's own description from evidence of its contract terms and sourcing requirements.
- Treat sample, rights and delivery checklists as preparation aids, not guarantees of acceptance.
- Confirm current terms directly with a prospective counterparty before sharing confidential material.
Limits
We have not tested any provider's service. Company descriptions reflect their own public pages on the date checked. Nothing here is legal advice.
