Why AI training matters

AI training (data labeling/annotation) is the human work that teaches AI how to understand the world. Contributors do hands-on tasks—like writing captions and describing scenes—that directly influence how models interpret video, audio, and text.

This work is mostly remote, flexible, and accessible: many projects need strong language skills and attention to detail rather than prior technical degrees.

• Flexible, part-time contractor roles you can do from home
• Entry and intermediate tracks exist; specialist experience can unlock higher pay

The role

We’re hiring Narrative Video Caption Writers to create single, scene-focused captions (50–250 words) for short video clips that support scene understanding, accessibility, and metadata.

This is contract, part-time work with a minimum expectation of 20+ hours per week. Candidates must be USA-based native English speakers and have reliable internet for streaming.

• Captioner rate: $25.75/hr
• Senior QC rate: $33.00/hr
• Employment: Contractor, Part-time

What you'll do

For each clip you will produce one clear, factual caption that helps a viewer understand setting, characters, actions, and emotion without speculation.

An initial calibration phase tests accuracy and style; after calibration you move into ongoing production or QC work depending on track.

• Establish setting and background audio in the caption
• Describe key characters, actions/interactions, and overall emotions
• Include pertinent on-screen dialogue (as presented) and identify clearly recognizable public figures or brands when visible
• Avoid naming shows/movies, speculating beyond on-screen content, or over-describing irrelevant background characters

Requirements

You must be a native English speaker based in the USA with reliable internet for streaming video.

Prior hands-on experience is required in at least one of the following fields: audio description (DVS), closed captioning/subtitling (SDH), narrative/creative writing, journalism/editorial writing, or script coverage/story analysis for film/TV.

• Follow detailed style guides and maintain strict factual discipline—no AI-assisted writing or machine translation
• Produce clean, native-English prose suitable for accessibility and scene understanding
• Minimum commitment: 20+ hours per week

Senior QC — additional expectations

The Senior QC track is for experienced editors and caption QA specialists who provide precise written feedback and enforce style across teams.

Senior QCs resolve edge cases against a rubric, enforce consistency, and mentor captioners through constructive notes.

• 2+ years in editorial QA, copyediting, or caption QA required
• Demonstrated style-guide/rubric enforcement and ability to give constructive writer feedback
• Experience resolving edge cases and maintaining style consistency
