Where Does the Dia Browser Store Data?
Dia browser profile, skills and AI workspace data per OS.
Last updated
Dia builds on Chromium conventions with a per-OS user-data folder for profiles, skills, tabs and AI workspace state. Treat it like a Chrome profile with an AI memory layer on top.
Export skills and memory before reinstalls since sync coverage varies. Profiles copy between machines like Chromium ones when versions match.
Where Dia stores this, by platform
%LOCALAPPDATA%\Dia\User Data
Chromium-style profile tree with Default profile, skills and workspace state. Copy with Dia fully closed. Exact vendor folder casing may vary by release channel.
~/Library/Application Support/Dia/User Data
macOS profile mirror. Open through Finder Go to Folder. Same closed-before-copy rule.
Frequently asked questions
Can I migrate Dia profiles to a new Mac?

Where are Dia skills stored?
Inside the profile tree above alongside tabs and workspace state. Export from inside the app for portable backups.
