FAQ
Questions, answered honestly.
Is Serideo live today?
Not yet as a self-serve platform. Serideo is pre-MVP — we currently run annotation projects hands-on with our trained annotator network, and have delivered paid pilot work. The platform, dashboards, and AI-assisted tooling are in active development.
What languages are supported?
Today we focus on 17 Asian languages: Hindi, Bengali, Telugu, Marathi, Tamil, Urdu, Gujarati, Kannada, Malayalam, Punjabi, Odia, Assamese, Garhwali, Maithili, Bhojpuri, Mandarin Chinese, and Korean. Coverage will expand as the annotator network grows.
How are annotators vetted?
Every annotator passes a skills assessment before being matched to live projects, and delivered work goes through a separate reviewer pass before it reaches you.
How is data kept confidential?
Client data is shared only with the annotators assigned to your project, and we work under NDA on request.
