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 Project Euler 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
📹 2. YouTubers & Content Creators Want to share drafts and get feedback from co-creators or sponsors
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
