Why does my AI assistant forget everything?
Because most assistants never knew it in the first place. A chat assistant sees the words you type into it, and sometimes a short memory of past chats. It does not see the meeting that just moved, the email you have not answered, or the night of bad sleep that makes a hard afternoon a bad idea.
So every conversation starts cold. You re-explain your week, your priorities and your constraints, and the answer you get back is generic because the question arrived without its context.
What is the difference between chat memory and a context engine?
Chat memory remembers what you told it. A context engine reads what your systems already know, and keeps reading.
| Aspect | Chat memory | Context engine |
|---|---|---|
| Learns from | What you type in the chat | The apps you connect, continuously |
| Knows about today | Only what you mention | Your calendar, inbox and health, as they change |
| Organised as | A list of remembered facts | One graph across work, money, health and life |
| When you start a question | From a blank chat | From your current day |
What does a context engine actually read?
Only what you switch on. In Deci, every module is optional — turn on only what you need, and everything you switch on feeds the same Life graph. Today that means:
- Gmail, read-only, for Inbox Radar — it surfaces what needs a reply and files the rest.
- Your calendar (Google or Outlook), so the planner knows where your day is already committed.
- Health data — steps, sleep and heart rate — for Health OS.
Deci reads from that graph rather than from chat history. As it describes itself: your life intelligence layer — I read from your Life Knowledge Graph, not chat history.
How does context change what AI can do for you?
It changes the question from "what should I do?" to "what should I do today, given everything else?". Take an ordinary morning:
Your calendar already has a 10:00 review and a 14:00 call
The planner sees both, so it does not offer those hours for anything else. Deci only schedules around what it can see.
Two emails are waiting on you
Inbox Radar has flagged them as needing a reply, so they are in view before you plan around them.
None of that requires you to explain your day first. The context is already there.
Is it safe to give an AI this much context?
It should be your call, and reversible. In Deci, your context stays yours — private and encrypted. Tokens are stored encrypted, and you can disconnect any app at any time; your Life graph keeps what it already learned. Inbox Radar reads, never sends: nothing leaves without you.
Key takeaways
- Most AI assistants forget you because they only see the chat, not your day.
- A personal context engine keeps a live graph of your work, money, health and life.
- With that context, AI can plan around what is actually happening — without you re-explaining it.
- In Deci, every connection is optional, read-only where it matters, and can be removed at any time.
Frequently asked questions
What is a personal context engine?
A personal context engine continuously turns the apps you already use — calendar, email, health and more — into a Life Knowledge Graph, so AI can answer from your real context instead of starting from a blank chat.
Does Deci send email for me?
No. Inbox Radar reads Gmail read-only to surface what needs a reply. Deci reads, never sends — nothing leaves without you.
Which apps can Deci connect to today?
Gmail (read-only, for Inbox Radar), your Google or Outlook calendar (for the planner), and health data such as steps, sleep and heart rate (for Health OS).
Can I disconnect an app later?
Yes. Tokens are stored encrypted and you can disconnect any app at any time. Your Life graph keeps what it already learned.
