One searchable workspace for every
research decision
How OpenAI's research teams replaced fragmented docs, wikis, and spreadsheets with a single encrypted library that keeps experiment notes, model decisions, and institutional knowledge instantly findable.
The challenge
Research moves fast — documentation couldn't keep up.
At OpenAI, a single model training run generates hundreds of artifact pages: hyperparameter logs, ablation study notes, architecture decision records, safety review memos, and post-mortem wrap-ups. Before VaultBook, these documents lived across Google Docs, Notion pages, scattered markdown repos, and personal notes apps.
When a researcher needed to answer "Why did we choose this reward function six months ago?" the answer was buried in a thread inside a doc inside a folder no one remembered sharing. Knowledge didn't disappear — it just became invisible.
"VaultBook is a single place where research, notes, and decisions stay searchable. That sentence sounds simple, but it changed how our team operates."

The results
Measurable impact across research velocity and knowledge retention.
Within four weeks of adoption, VaultBook became the default destination for all research documentation. The team indexed over 12,000 entries — experiment logs, architecture decision records, literature summaries, and safety review notes — into a single local library.
Document retrieval time dropped by 73 percent. Researchers no longer opened five tabs and searched three different platforms to answer a question about a past decision. More importantly, institutional knowledge stopped evaporating. When team members transitioned between projects, their notes stayed searchable and contextually linked to everything that came after.
The security team approved VaultBook faster than any previous tool. No data leaves the device. No API keys. No analytics beacons. For a team handling sensitive model capabilities research, that single architectural fact removed months of compliance review.
"For the first time, we have a knowledge base that researchers actually use — because it finds what they need without forcing them to remember where they put it."
