A general chatbot knows the internet but nothing about your company. A RAG agent knows your documents.
RAG stands for retrieval-augmented generation. The idea is simple: before the AI answers, it first looks up the relevant parts of your files, then writes its answer from what it found.
How it works
- Your documents (policies, price lists, manuals, past proposals) are split into small pieces and indexed.
- A person asks a question.
- The system finds the pieces most related to the question.
- The AI writes an answer using only those pieces and shows which documents it used.
Why show sources
An answer with a source can be checked in ten seconds. An answer without one has to be trusted. For anything involving policy, pricing or compliance, always show the source and make it easy to open.
Where RAG agents fail
- Old or messy documents. If two files disagree, the agent may pick the wrong one. Clean your documents first.
- Missing information. A good agent says "I could not find this" instead of guessing. Test that it does.
- Private data. Decide who may see what. An intern should not be able to ask the agent for salary files.
What multi-agent means
One agent can do one job well. A multi-agent setup splits a larger job between several, each with a clear role: one reads incoming emails, another looks up the answer in your documents, a third drafts the reply, and a person approves it before it goes out. Smaller jobs are easier to test and fix.
The AI second brain
The same idea works for one person. An AI second brain holds your notes, meeting records and reading, so you can ask "what did we agree with that client in March?" and get an answer with the note it came from.
Good first projects
- An internal helpdesk for HR or IT policy questions.
- A sales assistant that finds the right case study or price sheet.
- A training assistant that answers questions from course material.
Pick one, with a clear set of documents, and test it with real questions from your team.
