As answered by people managing Revievv and Coggle.
Revievv's answer
Reviewers don't need a CAD license, an account, or any installed software. Just a link. Most design review tools charge per seat or require everyone to have CAD software. Revievv gives unlimited free reviewers on every plan - so your suppliers, clients and cross-functional teammates can give feedback without any barriers.
Revievv's answer
Some competitors costs six figures and takes months to deploy. Revievv starts at $0, works in 30 seconds, and does what engineering teams actually need: open a CAD file, pin comments on the 3D model, share a link, collect feedback. No procurement process, no IT department required.
Revievv's answer
Mechanical and electrical engineers in teams of 5-50 people — product design, manufacturing, automotive, aerospace. Engineers who send STEP files by email, mark up screenshots in PowerPoint, and lose feedback in chat threads. Also useful for engineering managers who need documented, traceable design reviews instead of meeting notes in Excel.
Revievv's answer
Built by an engineer with ADHD who got tired of the same broken design review process, also had problems with doing all those related topics — screenshots in PowerPoint, feedback lost in email threads, "see attachment page 3 top left corner." Every CAD collaboration tool was either enterprise-priced or view-only. Revievv fills the gap: real design review with 3D markup, simple enough to start in 30 seconds, affordable enough for a small team.
Revievv's answer
Three.js for 3D rendering, OpenCascade for STEP/STL geometry processing, Next.js for the web application, and cloud infrastructure for file conversion. Everything runs in the browser — no plugins or desktop installation needed.
Revievv's answer
Revievv is an early-stage product used by small and mid-size engineering teams. We're focused on onboarding our first 100 customers — teams that need fast, affordable design review without enterprise overhead.

I find that reflecting on my experiences and going out of my way to really analyze the pitfalls and things done correctly helps a lot. I normally use coggle.it to mind map the whole experience overview and then which elements of the... Source: over 3 years ago

I have spent more time than I'd like to admit researching the different programs out there. Mindmup , Coggle, and Mindmesiter came the closest, but definitely not perfect. These are some of the features I am looking for:. Source: about 4 years ago
