Couples-only iPhone beta
Sotto
A private messenger for couples, with a quiet AI layer that remembers plans, commitments, emotional context, and the small details that usually vanish in the thread.
Chat first
Text, voice, photos, reactions, and plans in one two-person space.
AI with restraint
Sotto waits for enough shared context before it starts chiming in.
Shared by design
Private prompts support clarity, not strategy against your partner.
Quiet assist
Sotto helps you remember the plan, read the room, and return to the thing that matters.
Built for two
Not a relationship dashboard. Not another inbox.
Sotto is a messenger first. The intelligence is there when it is useful: remembering what was promised, spotting the pattern in a recurring misunderstanding, or turning yesterday's thread into a note you can actually use today.
Context before advice
The assistant observes first. It does not rush to label a moment before it has enough of the relationship's rhythm.
Helpful, not performative
Daily notes, reminders, and Sotto answers are direct, grounded, and practical. No therapy-speak, scorekeeping, or dramatic prompts.
Presence without surveillance
Optional location tags and battery status answer normal couple questions without broadcasting exact coordinates or turning care into monitoring.
Not therapy. Not a judge. Not a mind reader.
Sotto speaks humbly from the messages it has seen. It can support memory, perspective, and logistics; the relationship stays with the people in it.
How it comes alive
Sotto starts quiet, then becomes useful.
It does not need a setup questionnaire to become intimate. It learns from the conversation itself, then packages the useful parts back into the places a couple actually checks.
Pair privately
Create a two-person space through a private invite and choose the colors that become your shared Sotto mark.
Chat as usual
Messages, voice notes, photos, reactions, read state, and small status signals live in one focused thread.
Build memory
Sotto tracks commitments, dates, recurring moments, and communication patterns in structured notebooks.
Get the useful version
Morning notes and direct answers turn the history into reminders, context, and calmer ways back into the conversation.
Product surface
The intelligence stays inside the messenger.
Sotto does not ask couples to manage another system. The app looks and feels like a private chat, while the assistant works in the background to make the chat easier to return to.
A familiar private chat
The couple's thread remains the center of the product. Sotto appears when a daily note or answer is ready.
Ask without digging
Ask Sotto what was decided, what still needs attention, or how to re-enter a moment without scrolling for an hour.
Status that reduces check-ins
Saved places and motion tags can answer "are you still at work?" without exposing a live map.
Controls built for intimacy
Discreet notifications, battery sharing, location tags, daily notes, and media controls are opt-in surfaces.
Memory layer
The details get organized while the chat stays human.
Under the surface, Sotto turns a messy thread into practical notebooks. The point is not to archive everything; it is to bring back the right detail at the right time.
Promises and commitments
Who said they would book it, buy it, pick it up, or follow up.
Dates, trips, routines
Plans that appeared naturally in chat without turning into manual admin.
Patterns and repair
Recurring tension, softer moments, and what helped the conversation recover.
Partner profiles
Stable preferences, sensitivities, communication style, and what not to do.
Privacy model
Private by architecture, not by slogan.
Sotto is built in-house because intimacy creates different requirements than ordinary messaging. The app is designed to keep full history, keys, and media where they belong: on the couple's devices.
End-to-end encrypted messaging
Device-to-device communication is encrypted, with the server acting as a relay rather than the long-term archive.
Media files stay on device
Photos, videos, and voice notes are not sent in full for AI processing. Sotto works from transcripts and descriptions where needed.
Scoped AI processing
Recent context can be decrypted for a specific analysis job, then deleted after processing and sync.
Outputs are temporary on the server
Briefs, insights, and structured notes are held only as needed to reach both devices.
Now in private iPhone testing.
Sotto is for couples who want a messenger that remembers the real stuff without making the relationship feel managed.
