“I recently used BugSmash for a website project where I needed to gather feedback without the hassle of scheduling meetings. The platform allowed me to record an asynchronous video using OBS, which I then uploaded to BugSmash. Clients were able to comment on specific timestamps of the video as I posed my questions, and surprisingly, even those who aren't very tech-savvy managed to provide insightful feedback. I had previously attempted similar processes with other platforms like Loom, but BugSmash stood out since it requires no sign-in (optional)—users simply add their name. Overall, the value and affordability of BugSmash make it an impressive choice for anyone needing a comprehensive review solution for PDFs, images, audio, video, and live websites.“
