Revievv lets engineering teams review 3D CAD models (STEP/STL), PDFs and images directly in the browser. Pin comments on specific points of a 3D model, track issues with severity levels, and share a review link โ reviewers don't need a CAD license or even an account.
Upload a STEP file, invite your team or suppliers by link, collect feedback with precise visual context. No more screenshots in PowerPoint, no more "see page 3, top left corner" emails.
Key features: - 3D STEP/STL viewer in the browser โ no plugins, no installation - Pin comments directly on 3D model surfaces - PDF and image review with annotations and measurements - Share review links โ unlimited free reviewers on all plans - Issue tracking with severity, status and deadlines - Export review as PDF with all annotations - Wire tracing on electrical schematics
Free plan available. No credit card required.
A startup from Katowice, Poland that is founded by Tomasz Turek.
3D STEP/STL viewer in the browser
Open and inspect 3D CAD files directly in your browser. No CAD license, no plugins, no desktop software required. Works on Mobile as well.
Pin comments directly on 3D model
Click any point on a 3D model to pin a comment with exact visual context. No more describing "the corner on the left side."
PDF and image review
Review technical drawings, schematics and images with markup tools, distance and angle measurements โ all in the browser.
Share review links
Send a link to anyone - suppliers, clients, teammates. They can view and comment without creating an account or paying for a seat.
Issue tracking with severity
Assign severity levels, set deadlines, track resolution status. Every comment becomes a trackable issue.
Export review as PDF
Generate a PDF report with all comments pinned on the model or drawing. Ready to share with stakeholders or archive.
Wire tracing on PDF
Click a line on an electrical schematic โ the system highlights the entire connected circuit through connectors and branches. One click instead of tracing by eye.

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.
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.
Mechanical and electrical engineers in teams of 5-50 people โ 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.
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 โ 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.
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 โ no plugins or desktop installation needed.
Revievv is an early-stage product used by small and mid-size engineering teams. We're focused on onboarding our first 100 customers โ teams that need fast, affordable design review without enterprise overhead.
Revievv appears to be a solid choice for businesses looking to collect, manage, and showcase customer reviews, though prospective users should verify current features, pricing, and support directly given the evolving nature of review management platforms.
