Powering next-generation AI with reliable, human-driven data

Serideo is a data annotation company focused on code-switched and dialect-heavy Indic and Asian languages. We help AI teams train and evaluate models on how people genuinely speak, not just textbook language.

A Serideo partner is anyone contributing language expertise to our projects: annotators, reviewers, and native speakers who help label, translate, and verify data. Partners are matched to projects that fit their language background and skill level.

Earnings depend on the project's complexity and your language expertise, so they vary pilot to pilot. Annotators on Serideo have generally earned more than on comparable gig platforms, pay reflects expertise, not a flat rate.

We work across 17 languages in total: all 12 of India's official languages, 3 additional local and regional dialects, and 2 major Asian languages, Mandarin and Korean. Our live application tracks today focus on Hindi and Tamil, with more opening as our annotator base grows.

Yes. Client data is handled under NDA by default, with access restricted to the annotators and reviewers directly assigned to a project. We're happy to work within your existing data-handling or compliance requirements, just ask in the Get in Touch form.

Across completed pilots, we've helped clients reach 91.5% model accuracy on an internal benchmark, a 24.3% word error rate on a Tamil speech model, and delivered over 10,000 Hindi-English code-switching annotation tasks. Full detail on each is in the Our Work section above.
