Carrier is a web-app series exploring scriptwriting, voice mirroring, and prompt-driven development. Its latest iteration, CarrierSky, is a work-in-progress tool calibrated around nutritionist Ryan Fernando’s voice, tone, and language, currently targeting up to 60% stylistic accuracy. The idea came from Rohan Pius’s work at Qua Nutrition, where he writes scripts for Ryan’s YouTube Reels and long-form videos. After studying Ryan’s published transcripts and identifying recurring patterns in his language and delivery, Rohan initially explored using an LLM to generate scripts in Ryan’s style. But he took the idea further: instead of having AI write the script, why not build something that tells the writer where they are going wrong? CarrierSky therefore focuses on analysing original scripts, identifying weaknesses in tone, structure, language, scientific grounding and other patterns, helping the writer improve rather than replacing them. CarrierSky is still a work in progress, with its rules and calibration continuously evolving through research and real-world writing.
