You know what to reply. Sayso knows how to say it so they'll actually care — the right tone, the right language, the version you'd write if you had thirty seconds instead of three.
Three moments you've been in this week. You had the reply in your head — just not the version you'd actually be proud to send.
Speak the messy, honest version. Sayso writes the one they'll actually read right. Same meaning. Better you.
Hold to speak. Swipe to pick a mode. Sayso does different work in each — but it's always the same gesture, always under a second.
Reads the conversation, picks up the tone, writes the reply that fits. You mumble "playful but not thirsty" — Sayso delivers it, in the language they read in.
Ask a quick question without leaving the keyboard. Sayso answers inline — fact, definition, math, word origin, whatever. You copy or send, never switch apps.
Sometimes you want the raw thing. Voice notes, journaling, a message that's supposed to sound like you at 11pm — dictation mode transcribes, doesn't polish.
Five things that make Sayso feel less like a keyboard and more like someone writing your replies for you.
iMessage, WhatsApp, Tinder, Slack, Gmail, Instagram DMs. Install once, summon from the globe key, done. No copy-paste, no tab-switching.
Not word-for-word conversion. Sayso rewrites your reply the way a fluent speaker would actually write it — to a friend, a boss, a date. Register included.
Confident. Warm. Apologetic. Dry. Flirty. Sincere. Sayso learns which ones are yours and puts them first.
Names. Languages. Past tone. Inside jokes. Whether Mom prefers Spanish or Spanglish. Sayso keeps a quiet per-person memory so the tenth reply feels as natural as if a friend ghostwrote it.
Voice is processed per turn and discarded. Messages aren't stored on our servers. Memory lives on your device — you can wipe any person, any time, or turn memory off entirely. On-device mode available for Pro.
No onboarding. No tab-switching. Three beats between "I need to reply" and "delivered."
Tap and hold the Sayso key in any chat. Speak the raw version — "tell her I'm swamped but I'll make it next weekend, warm tone." Ums and pauses don't matter.
Reads the conversation, picks up tone and language, writes the reply you would have written with more time. Want it shorter, warmer, in Spanish? Swipe.
Output lives inside your keyboard — tap once to send, hold to edit first. Never leaves the app you're in. No copy-paste, no "sent from Sayso."
We built Sayso for the kinds of replies you rehearse in your head and never quite land. Here's what it looks like in each.
You matched in Madrid last summer. Her Spanish is faster than your Duolingo. Sayso writes replies that sound like a fluent, funny version of you — in her language.
Pushback is the skill nobody taught you. Sayso phrases the boundary you want to hold — firm, professional, nothing passive-aggressive, nothing you'll regret at 11pm.
Your Spanish got rusty. Your mamá's WhatsApp didn't. Sayso handles register, nicknames, the small affectionate things — so "sorry I missed Sunday" lands like you meant it.
Q&A mode turns the keyboard into a translator-answerer-concierge. Ask what something means, how to reply politely, what time the izakaya closes — answer stays in the thread.
