AI memory: how assistants remember
Guides on AI assistant memory: how it differs from the context window, what to check before choosing a memory-enabled assistant, and what happens when you switch.
These guides explain what "memory" means in practice for an AI assistant: what stays inside a conversation versus what persists across sessions, what to check before choosing a memory-enabled assistant, and what portability looks like when you switch providers.
SentX SI's memory is selective — it retains and recalls differently depending on use, and it does not guarantee exact retention of specific exchanges; other systems may work differently. How it works in SentX SI is described on AI chat with memory. Because submissions to SentX SI are not treated as confidential (see the privacy policy), the guides also note what is reasonable to share with SentX SI specifically.

A practical starting point
- State the goal, useful background and facts that must stay exact.
- When you return, confirm important details. Selective memory is not a transcript or a guarantee of recall.
- Review the data and memory policy before sharing material that matters to you.
