Short answer
If the product only uses the live context window, it will forget. For an AI girlfriend that still knows Day-1 facts a week later, you need long-term memory outside that window (summaries + retrieval). Primary pick: Candy AI.
Jailbreaking a short-memory app does not add a database. Switch architecture — see the AI girlfriend apps audit.
Why “she forgot” is usually a token limit
LLMs meter history in tokens. Free/small tiers often sit around an 8k ceiling; even larger windows fill fast with roleplay.
- Overflow — oldest turns drop to make room; named facts vanish.
- Looping — attention collapses into repeated phrases.
- Hallucination — the model invents glue to fill gaps.
Rolling chat summaries help a bit but still lose detail. Durable companions need a separate memory store.
What good LTM looks like
- Extract — pull stable facts (name, preferences, plot anchors) from the stream.
- Store — keep them as structured notes or embeddings off the hot context.
- Retrieve — on each turn, inject only the relevant memories into the prompt.
That RAG-style loop is what Candy AI optimizes for: core memories survive idle days, and check-ins can still reference earlier sessions without you re-pasting a mega-prompt.
Quick comparison
| Approach | Storage | Typical recall after heavy use | Example |
|---|---|---|---|
| Raw context only | Live window | Near-zero on old facts | Generic free bots |
| Rolling summaries | Compressed transcript | Partial; detail loss | Many legacy apps |
| LTM / retrieval | External memory + prompt inject | Strong on core facts | Candy AI |
How to test in 10 minutes: plant 5 odd facts early → chat normally for a long session or return next day → ask for each fact without hinting. Score hits, not vibes.
Primary pick: Candy AI
Use Candy when the girlfriend use-case is weeks of continuous NSFW/SFW chat with continuity. Deep Mode keeps adult policy on-product; memory is the reason to pay, not a side toggle. Confirm Delete Account if privacy matters (privacy hub).
