Sam Altman says he likes to take notes using pen and paper. Altman says he prefers to use a spiral notebook because he can rip its pages out when needed. The OpenAI chief said he uses pens from Uni-Ball and Muji to jot things down.

OpenAI CEO Sam Altman likes to take notes the old-fashioned way — using pen and paper. Altman was speaking to writer David Perell on the latter's podcast, "How I Write," when he talked about his note-taking preferences. Perell posted a short clip from their September 5 conversation to X on Monday.

During the exchange, Altman called himself a "huge note taker" and said he gets through one notebook every two to three weeks. "There's all these like fancy notebooks in the world. You don't want those.

You definitely want a spiral notebook because one thing that's important is you can rip pages out frequently, and you also want it to lie, like, flat and open on the table," Altman told Perell. Altman added that he likes notebooks with hard front and back covers that fit in his pocket. The OpenAI chief also talked about the two favorite pens he liked to use to take notes.

37 in dark blue ink is a very nice pen for other reasons. So those are the two I would use," Altman said. "I think this kind of notebook and one of those two pens is the right answer," Altman added.
