Since I started my career in videography, one thing that’s always been a challenge is finding the right platform to share videos with clients for feedback. Most options were either clunky, expensive, or just didn’t fit how I work. So… I decided to build my own. I’ve created a new review platform...

As answered by people managing CheckIO and ClipNotesPro.
ClipNotesPro's answer:
Don't pay for expensive storage! Most platforms require full uploads before reviewing. ClipNotesPro lets users simply paste a YouTube link, no re-encoding, no upload delays.
Faster setup, no storage limits, and no redundant uploads.
ClipNotesPro's answer:
Made for Creators, Not Corporates Platforms like Frame.io are made for large post-production teams and studios. ClipNotesPro is built specifically for content creators, editors, and freelancers.
ClipNotesPro's answer:
Freelance Videographers & Editors Need a quick way to get feedback from clients
Don’t want to deal with big software like Frame.io
Often work solo or with small client teams

Benefit from the YouTube URL integration
Prefer simple, no-login tools for collaboration
👥 3. Small Production Teams or Agencies Manage multiple projects with multiple clients
Need timestamped feedback and approvals to keep workflows tight
Don’t need bloated enterprise features
🤝 4. Clients Giving Feedback (Non-Tech-Savvy Users) Business owners, marketing managers, or collaborators
Prefer clicking a link and commenting, not creating accounts or learning new software

Since I started my career in videography, one thing that’s always been a challenge is finding the right platform to share videos with clients for feedback. Most options were either clunky, expensive, or just didn’t fit how I work. So… I decided to build my own. I’ve created a new review platform designed specifically for video creators to simplify the review process, making it easier to send videos, get feedback, and keep projects moving smoothly. If you’re a videographer/video editor or know someone who is I'd be grateful if you shared it with them. While only launching at the end of the month the site is live with a bunch of features still to come
