“we actually ripped out all the localization infrastructure we built our own GitHub action and there's like a thin library which just extracts the strings or wraps all the strings and then each time we make a PR to our repo it just sends it with like a prompt per language about the localization guide and that means we're able to localize like way cheaper and much faster”

Replace expensive localization SaaS with a GitHub Action and LLM prompts

ElevenLabs was paying an agency and an expensive SaaS for localization until engineers noticed that ChatGPT consistently produced better translations. They replaced everything with a GitHub Action: on every PR, a thin wrapper extracts strings and sends them through a per-language LLM prompt. The result is faster, cheaper, and more natural-sounding copy — making full localization of ads and app store listings practical for any team.
