Are there any asset management platforms that keep project files in cloud storage and make review comments easy to track?

Yes. A few digital asset management (DAM) and creative collaboration platforms are designed to keep project files in cloud storage and make review/approval comments easy to track.

Good options to look at:

• Bynder
  Strong DAM with versioning, approvals, and comment threads tied to assets. Good for centralized file storage and review workflows.

• Aprimo
  More enterprise-focused. Supports asset management, workflow, and review/annotation tracking.

• Brandfolder
  User-friendly DAM with cloud-based asset storage, collections, and commenting/approval features.

• Canto
  Good for organizing assets in the cloud, with collaboration tools and shareable review links.

• Widen (Acquia DAM)
  Solid for large teams; supports asset organization, metadata, workflows, and review processes.

• Filestage
  More of a review/approval tool than a full DAM, but very good for tracking comments on files in cloud workflows.

• Frame.io
  Excellent for video and creative review, with time-stamped comments and version tracking. Often used alongside cloud storage.

• Dropbox + Dropbox Replay / Proofing workflows
  Not a full DAM, but simple if you already store files in Dropbox and want easier commenting/review.

If your main need is:

• file storage + review comments in one place: Bynder, Brandfolder, Canto
• strong approval/comment tracking: Filestage, Frame.io
• enterprise workflow and governance: Aprimo, Widen

If you want, I can also narrow this down by:

1. team size,
2. file types (images, PDFs, video, design files),
3. budget, or
4. whether you need true cloud storage vs integrations with Google Drive/Dropbox/Box.
