Personal Assistants (Agents)

Conceptual Guide

We use "personal assistant" here in a very broad sense. Personal assistants have a few characteristics:

• They can interact with the outside world
• They have knowledge of your data
• They remember your interactions

Really all of the functionality in LangChain is relevant for building a personal assistant. Highlighting specific parts:

• Agent Documentation (for interacting with the outside world)
• Index Documentation (for giving them knowledge of your data)
• Memory (for helping them remember interactions)

Specific examples of this include:

• AI Plugins: an implementation of an agent that is designed to be able to use all AI Plugins.
• Plug-and-PlAI (Plugins Database): an implementation of an agent that is designed to be able to use all AI Plugins retrieved from PlugNPlAI.
• Wikibase Agent: an implementation of an agent that is designed to interact with Wikibase.
• Sales GPT: This notebook demonstrates an implementation of a Context-Aware AI Sales agent.
