About AI training and annotation work

Human annotators prepare and review examples that AI systems learn from—tasks include transcribing, labeling audio/video, and evaluating quality. This role directly contributes to how models understand and generate language and media, and is often remote and flexible.

The role

We are seeking Slovak annotators based in Slovakia to review transcripts of video content and assess transcription quality. This is a short test project with possible extension to longer-term work for high-quality contributors.

• Pay: USD 9.00 per hour (PAY_PER_HOUR).
• Data type: Video; label type: Audio recording.
• Annotation platform: OTHER (you will use the project's provided annotation tool).

What you'll do

Follow project guidelines to review video transcripts and mark errors. You'll identify whether transcripts contain major, minor, or no errors, describe each issue, and provide the relevant timestamps.

• Read and compare transcripts to the video/audio to assess accuracy.
• Assign severity labels: major, minor, or no errors.
• Describe each error clearly and provide precise timestamps for occurrences.
• Use the project's annotation tool (OTHER) and submit annotations per guidelines.
