Appen and Deepen AI Services both supply human work for AI, for different jobs. Appen sells data products, licensed datasets and an annotation platform to teams building AI models, backed by a contributor crowd. Deepen AI Services puts a managed team inside your own tools for repeatable data tasks, at a published rate. If you are building a model and need data across many languages or domains, Appen is designed for that. If you have steady operational data work and want a named team, read on.
When Appen is the better fit
- You need data in many languages. Appen's homepage cites "500+ global locales covered."
- You want to license existing training datasets with spec sheets instead of commissioning new work. Its data catalog lists datasets by category.
- You need domain experts for reasoning, coding or alignment data, which Appen lists among its data products.
- You want your own annotators and an external crowd in one platform, with gold questions and multi-stage review built in.
- You work with protected health information and need the HIPAA-compliant environment its security page describes.
- You need speech corpora or physical AI data; both are among the six data products on its homepage.
When Deepen AI Services is the better fit
- Your work is operational and repeats: reviewing AI answers against a rubric, labeling support tickets, verifying extracted document fields, enriching product data or entering records.
- You want the work done in your own systems, not on an outside platform.
- You want a published rate before any call: $5 per person-hour for standard tasks, with the team lead and QA sampling included.
- You want to start small, with a two-week prepaid pilot and weekly reports.
- You want the same named people on your work, with a team lead you can talk to.
