Short answer
AI companion memory is not one feature — it layers:
| Layer | What it remembers | Example products |
|---|---|---|
| Session | Current chat window | Most bots |
| Short-term | Last N messages in prompt | ChatGPT-style |
| Long-term / diary | Facts across days | Nomi, Kindroid, Replika |
| Card/persona | Character file | Janitor, Character.AI |
AISoul focuses on companion-level continuity — nicknames, moods, story beats — in one girlfriend thread (personalized AI girlfriend).
Key takeaways
- Bigger context window ≠ human-like memory — products still summarize or forget edge facts.
- RP browsers (SpicyChat) often reset between bots — bad for one bond.
- Memory + images together matter — recalling a nickname while sending in-character photos feels cohesive.
How memory is built (technical plain English)
1. Your messages are stored (per privacy policy).
2. Each reply, the app sends recent history + sometimes memory summaries to the model.
3. Long-term products extract facts (“user likes coffee”) into a memory bank.
4. Limits — token caps mean very old details get compressed or dropped.
Product types compared
| Type | Memory strength | Tradeoff |
|---|---|---|
| Dedicated companion (Nomi, Kindroid, AISoul) | High for one partner | Not a 300k bot library |
| Character browser (SpicyChat) | Per-character | Bot-hopping breaks arcs |
| Card + BYOM (Janitor) | You control card | Setup effort |
| General AI (ChatGPT) | Thread-only | Not girlfriend-scoped |
How to get better memory (user tips)
- Use one companion — don’t split attention across 10 bots.
- Remind explicitly once: “Remember I work nights.”
- Don’t clear history unless you want a reset (delete chat guide).
- Pick apps that advertise long-term memory — see best with memory.
AISoul memory (product truth)
- Cross-session context for your one girlfriend per account
- Works alongside in-chat photos/clips — visual + text continuity
- Not infinite — abuse/fair-use policies apply
