  • Keep clear space equal to the height of the mark on every side.
  • Minimum size: 24 px tall on screen. Use the mark alone below 120 px wide.
  • Never recolour, stretch, outline or add effects. Use the dark version on #1C2420 and photography.
  • Pair with the SOMIN partner lockup only as “Technology partner SOMIN”, never merged into the GPT3 Marketing logo.

AI content that sounds like you, not like everyone else

We have been writing with language models since the summer the GPT-3 API opened in 2020. We build brand voice systems, prompt libraries and human-edited content operations, grounded in what your real audience responds to.

Personality

  • Crafted
  • Warm
  • Exacting
  • Unhurried

Voice: do

  • Use concrete examples over abstractions
  • Speak from experience, plainly
  • Name the trade-offs honestly

Voice: don't

  • Use hype words or trend-chasing slang
  • Pretend AI output needs no editing
  • Invent results or client stories

Imagery

Warm retro-futurist terminal scenes in cream, amber and green-black with risograph grain. Human hands and tools sit alongside machines, never replaced by them.

All imagery is generated with SOMIN image generation from art-directed prompts: no stock, no text baked into images, no identifiable real people.
