Interrupted expression
Questions, defenses, or emotion can redirect a story before either person explains it fully.

AI emotional narrative product · Plan V1.0
Life Exchange
Let both versions be fully seen without interrupting each other
Designed for two people who know each other but struggle to explain an experience. Private expression, separate confirmation, and shared narrative help both sides revisit the same event or period of life.
LIFE EXCHANGE / V1.001
Problem framing
Some experiences remain untold because there is no uninterrupted space
Instant chat invites reactions before a story is complete, while diaries remain private. Generic AI may generate text but rarely defines consent, visibility, and publishing boundaries for two people.
Unshareable material
Private notes preserve details but lack an appropriate way to organize and deliver them.
Unclear permissions
AI may help with language, but it cannot consent, publish, or expose the other person's private content.
02
Dual-perspective model
Two choice axes create four narrative paths
Choose an event or a period of life, then decide whether to complete it alone or invite the other person. Select a combination to see how its flow and outcome change.

Privacy by design
Protect expression before building shared understanding
In dual mode, both narrative tracks remain invisible to each other before submission. Shared output appears before source drafts, whose visibility follows rules confirmed in advance.
Each person sees only their draft, AI suggestions, and confirmation state. The other person cannot preview, rush, or edit it.
The system builds a shared story from locked snapshots while preserving common clues, both viewpoints, and unresolved differences.

Product decisions
Make understanding the outcome, not a relationship score
AI organizes, users decide
AI asks, structures, and drafts candidates; users confirm everything that is published.
No judgment, diagnosis, or relationship scoring.Solo journeys can finish
A user can complete a personal story without waiting for an invitation to be accepted.
No streaks, rankings, or pressure loops.Shared output preserves difference
The result includes common ground, A's view, B's view, and what remains unresolved.
No invented dialogue, motives, or reconciliation.Structured PRD · V1.0
Product requirements document
This web reading version is organized from the complete PRD. The plan still awaits open-question confirmation before engineering breakdown; the current demo and formal-product boundaries are stated separately.Context and positioning
Life Exchange is a desktop-first web product for two people in an existing relationship. It turns hard-to-explain experiences into readable personal or shared stories, while explicit submission, visibility, and confirmation rules protect both people's boundaries. Its goal is to help both sides see, not force agreement.
Target users and core needs
Two people in a close relationship
Tell the same event completely without turning an instant conversation into an argument.
People in a long-term relationship
Organize multiple moments across a shared period and compare different timelines.
Someone who starts alone
Finish their version first, then decide whether to invite, send, or reveal source content.
Product goals
- Reduce the pressure of starting
- Keep AI optional and require confirmation
- Keep dual narratives independent before submission
- Accumulate a life period through time and events
Non-goals
- No stranger matching or public community
- No instant chat or endless reaction feed
- No relationship diagnosis, scoring, or advice
- No streaks or participation pressure

End-to-end flow
- 01Set the rules
Choose scope, participation, delivery, and visibility before creating the relationship space.
- 02Express privately
Write independently, optionally use AI, and confirm the source material for generation.
- 03Submit and lock
Dual mode locks separate snapshots; neither source is visible until both submit.
- 04Build shared output
AI drafts a shared story that preserves differences; both people review and confirm separately.
- 05Read and archive
Read, respond, and reveal source drafts according to the agreed policy; resolve disputes before archive.
AI role and privacy boundary
AI assists expression; it is not a relationship judge. It can only organize user-confirmed material and cannot bypass publishing or access rules.
- Never send or consent for users
- Never invent dialogue, motives, or reconciliation
- Keep generated passages traceable to sources
- Allow rejection, regeneration, and dispute flags
MVP and current demo boundary
The current demo is a base-flow sample for one event, not evidence that the complete PRD is implemented. A formal MVP still needs server-side state, real identity and relationship spaces, dual snapshots, and Supabase RLS.
- Retain
- Current event writing, organization, preview, and reading components.
- Add
- Life timeline, dual snapshots, shared generation, proofreading, and dual confirmation.
- Refactor
- Replace browser-state permissions with a server state machine and Supabase RLS.
