grai - Founder Edition (Lifetime License)

Write like you. Prove it.

grai is a 622 KB single-file offline voice engine (grai.html) and a 5-file markdown instruction harness that locks any AI model to your real sentence rhythm.

Built after auditing 134,522 public posts from 1,499 founders (2023 to 2026), grai catches the structural habits that give ChatGPT and Claude away even after you delete banned buzzwords.
