PurpleBrain
AI that understands your business, not just your documents.
PurpleBrain turns the documents your work runs on — catalogs and spec sheets, case files and contracts, policy manuals and survey records — into knowledge your people can ask and your AI agents can use. Each answer cites the page it came from.
Your DENSE documents, ready for people and agents.
Example from a fictional pump catalog: asked which pump handles 450 GPM at 120 feet of head in stainless steel, PurpleBrain answers the KS-4x3-10 in 316 stainless and cites Catalog 300, page 42.
Your people and your agents need better knowledge.
People ask in chat and get an answer they can check. Agents use the same knowledge through a tool call — to draft a quote, respond to a survey deficiency, or trace a diligence finding. Start with the job that matters most.
Quotes drafted from your catalogs, every line cited.
A sales-engineering agent reads your catalogs, spec sheets, and past quotes, drafts the quote line by line, and hands it to a person to review. Your senior engineers stop being the bottleneck.
See expert knowledge capture →Your documents, ready for the agents you build.
We stand up the knowledge layer on your infrastructure in weeks and connect it to the agents your team builds. Your team owns all of it when we leave.
See the knowledge layer engagement →Every diligence finding, traced to its page.
A diligence agent answers across hundreds of documents — cap tables to debt docs to BOMs.

One wrong answer spreads faster than a right one.
Most AI tools will confidently guess. PurpleBrain is built so a guess can never become company truth.
Nothing here becomes company truth until a person approves it.
Source captured
Every document logged; nothing enters silently.
Claims extracted
Each fact tied to the exact page it came from.
Conflicts caught
Contradictions surface instead of hiding.
Human sign-off
A person approves before it counts.
Answers with receipts
Cited answers, or an honest "not enough evidence."
Agents are only as good as what they stand on.
Refuses to guess.
Most pilots die of distrust — one confident wrong answer and the team never opens the tool again. PurpleBrain agents work from your whole document set, read and connected — not loose snippets. When the evidence isn't there, they say so.
Built in production, not in a pitch deck.
The same production system proven on 20,000+ documents at a U.S. industrial equipment manufacturer — pointed at your business.
Show us your densest documents.
Bring a catalog, a case file, or a policy manual to a working session. We'll show you answers that cite the page, and an agent using the same knowledge.
Your message will be answered by a real person.
