Knowledge Base

The knowledge base is your personal memory layer for TabMail. Store facts about yourself, your work, and your contacts so the agent always has the context it needs.

Why use a knowledge base?

Without context, the agent treats every request in isolation. With a knowledge base, it knows things like:

Your role and responsibilities
Key contacts and relationships
Ongoing projects and deadlines
Communication preferences

This makes responses faster, more relevant, and less repetitive.

Adding knowledge

Through chat

Just tell TabMail what to remember:

“Remember that I prefer bullet points in my emails.”
“Note that John Smith is our primary contact at Acme Corp.”
“Save this: our fiscal year ends in March.”

TabMail also learns from your conversations automatically. When you share facts about yourself, your work, or your preferences during normal chat, the agent proactively adds them to your knowledge base — no need to say “remember” every time.

Through Prompts

Open Prompts from the TabMail popup.
Go to the Knowledge Base tab.
Add or edit entries directly.

What to store

Category	Examples
Preferences	“Use a formal tone with external clients.” / “Keep replies under 150 words.”
Context	“I’m the lead engineer on Project Phoenix.” / “We use Jira for task tracking.”
Rules	“Archive all automated CI notifications.” / “Flag emails from the CEO as high priority.”
Relationships	“Sarah is my manager.” / “The marketing team includes John, Lisa, and Michael.”

Managing your knowledge base

Over time, some entries will become outdated. It’s good practice to:

Review your knowledge base every few weeks.
Remove or update entries for finished projects or changed roles.
Add context when you start something new.

Privacy

Your knowledge base is stored locally in Thunderbird. When you invoke the agent, content is sent for processing but is not retained. You can always disable AI features at any time with a single toggle in your settings. For more details, see Privacy Policy.
