Not just one digital you — every version of yourself across time
Most AI twins only have a present version mixing your entire life experience, losing the authentic thinking of past years. NexMe「Aetern」 generates multiple independent stage persona snapshots, restoring the real you from each era.
Why It Matters
Generate multiple immutable stage persona twins from your timeline material. The 20-year-old twin will not know anything after age 40. Each stage persona fully preserves tone, worldview and cognition from that era. Old snapshots are never overwritten by new experience.
A vertical or circular timeline at center with multiple translucent figure silhouettes: teenage, young adult, career phase, family phase. Each twin has an independent memory halo and a cognition cutoff node. The user stands before the timeline, talking with one stage persona.
How to Use · Step-by-Step Guide
- Prepare material — Your life timeline accumulates enough material for that stage (text, voice, photos). The richer the material, the more authentic the twin.
- Trigger persona snapshot generation — Auto-trigger: when a life stage reaches the material threshold, you are prompted to generate a twin. Manual trigger: select a life stage and click Generate stage AI persona. Generation runs async in background; you will be notified when complete.
- Cognition boundary auto-applies — After generation, the twin carries a cognition cutoff time. During conversation, only memories before the cutoff are accessed; later life events remain unknown.
- Chat with stage persona twins — Open the timeline, tap a life stage, select Talk to this version of me. Text chat supported; if voice material exists, hear cloned voice in that era style.
- Version management — Editing memories never overwrites old snapshots — only generates new versions. All historical snapshots are permanently preserved.
Real-world Examples
Example · Talk to your college self
A user selects the university stage snapshot and talks to their 20-year-old self. The 20-year-old twin knows nothing about getting married or changing jobs at 30; tone and thinking remain in college era, revisiting the ideals and confusion of that time.
FAQ
Will new material auto-update old twins?
No. Old snapshots remain unchanged. New material is only used for twins at new points in time.
What determines persona authenticity?
The quantity and quality of stage material. The richer the material, the higher the fidelity of personality and tone.
Can I delete a stage persona?
Yes, select a snapshot and execute destruction. The system outputs a destruction certificate.
