Kord is version control for engineering document sets. Point it at a OneDrive folder and it imports what is there, then watches for changes: every later edit becomes a revision you can compare, review, and approve. OneDrive stays the system of record - Kord never moves, renames, or deletes a file without someone asking it to.

What the integration does

• See what changed. Side-by-side and overlay diffs for the formats an engineering package is actually made of - PDF drawings and P&IDs, DWG, Word, Excel, PowerPoint, images, STEP models, and Rockwell PLC projects.
• Review before it ships. Changed files are grouped into a review session - the engineering equivalent of a pull request. Reviewers comment, give a verdict, and publishing holds until the required sign-offs land.
• Comments end up in the file. Comments on a Word or Excel document sync both ways with the file's own native comments, so someone working in Office against OneDrive sees the review without opening anything else.

Connecting OneDrive

1. Each member clicks Sign in with Microsoft from Settings → Connected accounts, or the first time they link a folder. There is no organization-wide setup step - every member brings their own access.
2. Pick the folder to track. Kord imports it in the background and from then on the folder is linked - files keep a live connection back to where they came from, and "Open in OneDrive" goes straight to the file.
3. The same Microsoft sign-in also connects SharePoint - one consent covers both, so a member who has already connected OneDrive doesn't authenticate twice to also link a SharePoint site.

If your tenant requires multi-factor authentication and a member's stored access predates it, Kord asks them to reconnect rather than silently failing the next sync.

How sync behaves

Sync runs when someone asks for it. Kord does not poll your tenant in the background, and file content never moves on its own.

• New files apply silently. A file added to the linked folder shows up in Kord marked as new.
• Edits become a review session. A modified file is flagged "Modified in cloud" and staged as a new revision to review against the last published one.
• Deletions are marked, never mirrored. A file deleted in OneDrive is badged in Kord and stays visible. The deletion only takes effect when a review session containing it is published.

Security

• OAuth 2.0 against your own Microsoft tenant, requesting only the Graph scopes needed to read and write the folders you connect. No Microsoft password is ever seen by Kord.
• Tokens encrypted at rest with AES-256-GCM, scoped to the individual user who granted them, and revocable at any time by disconnecting the account.
• Where the bytes sit. Kord keeps its own version history of the files you track, so it can diff a revision against one deleted upstream months ago. Enterprise plans can keep that history in their own S3 bucket instead.

Requirements

A Microsoft 365 account with access to the folder you want to track, and a Kord account. Setup takes under a minute and doesn't need anything installed on anyone's machine.
