Built around how you actually write

Style cloning that actually works

null0 analyzes your real sent messages and builds a writing fingerprint. Your iMessage voice is casual. Your email voice is more formal. null0 knows the difference.

Never. null0 generates drafts — it never sends anything automatically. Every reply stays as a draft until you explicitly approve and send it yourself.

null0 analyzes your actual sent messages on each platform and builds a style fingerprint — tracking casualness, directness, warmth, humor, and brevity per platform.

Your message data is encrypted at rest and in transit. OAuth tokens are encrypted with AES-256-GCM. We use Supabase with Row Level Security. We never share or sell your data.
