Corazón app by Buena, the creative studio for good causes

Docs, knowledge bases and assets: the heart of the ecosystem.

Client: Buena apps
Year: 2026
What we did: App
Result: Live at corazon.buena.org, plus a native Mac app

Corazón is Buena's company brain: collaborative docs, knowledge bases and brand assets in one place, with an AI assistant that answers from what the team has actually written. Ask it a question and you get a grounded answer with links back to the source.

An agency's answers are buried across briefs, files and chats

An agency's knowledge lives everywhere: briefs, brand files, decisions, how-tos and the notes from last week's call. Most of it is written down somewhere. Finding it is the hard part.

When the answer is buried, people ask each other, or guess. Both cost time, and a guess about a brand rule or a client decision can travel a long way before anyone checks it.

General AI chat tools don't solve this. They answer fluently from the internet, not from what our own team has decided, and they rarely show where an answer came from.

A company brain that answers only from what the team has written

Put the docs, knowledge bases and brand assets in one AI-native workspace, then let an assistant answer from them. Every answer is cited back to the passage it came from. Knowledge is the source of truth.

Answers stay inside the workspace that asked. If nothing relevant is there, the assistant says so, and if only part of the answer is there, it says what it found.

Privacy is built in. Conversations with the brain are private to the person asking unless an owner shares them, and search only reaches the documents that person is allowed to see.

Docs
Collaborative documents with comments, and the assistant editing alongside you.
Wikis
FAQs, how-to guides and topic pages, every answer cited.
Assets
Buena's brand images and files, organized in one library.

A web app, a phone version, and the assistant one keystroke away on the Mac

The web app holds docs, wikis and assets. Documents take comments, and the assistant can make edits from them. The wiki builds FAQ, how-to and topic pages for each workspace, with every answer cited.

Corazón Chat is a small native macOS app. Press Control-Space anywhere and the assistant answers in a floating window, with source chips that open the exact passage and a small map from answer to project to document.

Under the hood, answers come from hybrid search, a claim check and answer feedback, tested against a set of evals. A phone version is built around chat, with docs and the wiki a tap away.

Live at corazon.buena.org, running Buena's own knowledge

Corazón is live at corazon.buena.org and runs Buena's own docs, wikis and assets. The first commit landed on May 29, 2026, and more than 200 have followed since. It also runs Ask, a small web app for asking it questions from any browser.

Corazón Chat is set up to ship as a signed, notarized Mac download, so it installs on a team Mac without security warnings. The same answers are on the web, on the phone and on the desktop.

Every answer can be traced to a source a teammate wrote, which is the whole point. That makes Corazón a tool we can check, not just one we have to trust.
