Print On Demand: DeepSeek AI Niche Research Guide

About this video

Martinez demonstrates using DeepSeek V3 for print-on-demand niche research on Merch by Amazon and in general. He notes DeepSeek’s benchmark comparisons against models including GPT, Claude 3.5 and Llama, then prompts it for top hobbies and interests in the USA (noting the country/state/city can be swapped), drills into gaming, and splits it into video gaming, board gaming and card gaming. Choosing first-person shooters, he asks for 10 t-shirt ideas that will make sales, getting lines such as ‘Lag is my only weakness,’ ‘Born to game, forced to work’ and ‘Press F to pay respects,’ then repeats the same prompt for board gaming (‘I paused my board game for this’). He repeatedly warns you cannot use Call of Duty, Monopoly or other protected properties, and shows checking phrases in TMhunt (up to 10 lines at once, filtering to live results, clicking through to USPTO records), plus Google searches for movie/song origins. Finally he builds ‘Lag is my only weakness’ in Kittl using a typography t-shirt template, edits it, removes the background and exports it.

Key takeaways

• Prompt DeepSeek broadly (top hobbies/interests by country), then drill into a sub-niche you personally know and like
• Ask for a set number (e.g. 10) of t-shirt ideas per sub-niche, then repeat the prompt for adjacent sub-niches like board gaming
• AI ideas are inspiration only — never use protected games/brands such as Call of Duty or Monopoly
• Check every phrase in TMhunt/USPTO (up to 10 lines, filter to live) and Google it for movie or song-lyric origins
• Turn a cleared phrase into a finished design quickly with a Kittl typography template and transparent-background export
