Atlan remembers why every decision was made — so new engineers ship in days, not weeks.
Every answer comes with the commit, the thread, and the person behind it.
Nobody wrote it down. So the next person starts from zero — again.
No migration. No new tool for your team to adopt. Atlan reads the history you already have.
Atlan connects to Git, Slack, and your ticketing system. No new tools to adopt.
Atlan builds a decision graph — what changed, why, and who was involved.
Any engineer asks "why is this built this way?" and gets a sourced answer instantly.
New hires get a path built from real project history — not a stale wiki page.
