SaySo

SaySo is an AI that writes the way you'd say it. Every AI writing tool makes everyone sound like the same polite assistant, and friends spot it in one message. SaySo learns how you actually text from your own chats (Telegram, WhatsApp or Instagram exports, or screenshots) and from your own emails and essays. Then it writes in your voice: your length, case, punctuation and slang, and the way you agree, joke or refuse, adapted to who you're talking to (partner, friends, family, elders). It lives where you write: • Its own iOS keyboard: type a rough draft, tap ✨ and pick one of 1–3 versions in your style, as one message, a series of short messages, an official message or an email. • Action Button / Back Tap: it screenshots any chat, Muse Spark reads it and offers three replies with different intents (agree / refuse / joke) in your voice. Pick one and it's copied. • A chat app with Write, Rewrite, Reply, Email and Essay modes. Essays are built only from your own notes and checked for AI clichés. There's voice dictation, and 👍/👎/✏️ feedback turns into rules ("keep messages to family short"). Results: • A personal QLoRA on Muse Glimmer 30B cut the stylometric gap to my real messages from 2.64 (base model) and 1.01 (few-shot) to 0.04. • It beat Muse Spark Open head to head on held-out rewrites (chrF 55.7 vs 49.3). • In a blind test, 5 friends (100 answers) told my real messages from SaySo's only 53% of the time, about chance level. You always press send yourself. SaySo is about keeping your own voice, not about hiding that AI was used.
