The generative AI boom has opened up a whole new category of gigs for freelancers: post-editing and "fixing" AI outputs. According to internal data from Freelancer.com, listings mentioning "fix AI," "AI hallucination," and "AI error" shot up 87% between August 2025 and June 2026—hitting 10,760 gigs. Over on Upwork, demand for pros who can clean up AI-generated content jumped 70% year-over-year.

Post-Editing AI: The Hottest New Service

Clients are on the hunt for talent who can whip AI-generated work into shape for publishing or commercial use: fixing mistakes, cleaning up weird artifacts, tweaking composition and style, and making sure the final product actually matches the brief. Job posts are now calling out "AI hallucinations" and the need to "fix AI" right in the requirements.

Top Gigs: Where the Action Is

Graphic design is leading the pack for these kinds of gigs. Next up: video editing, proofreading, and copywriting—basically, any area where hands-on polishing is needed to get rid of errors and make sure the end result is up to par.

Freelance Marketplaces: Freelancer.com and Upwork

The numbers from the biggest freelance platforms show this trend is here to stay: on Freelancer.com, these listings spiked 87% to 10,760 over ten months, while Upwork saw requests for AI content fixes climb 70% year-on-year. For freelancers, that's a steady stream of post-editing work. For businesses, it's clear that having a "human in the loop" is becoming the norm when working with generative tools.
