Browser-native CFD: upload a 3D model and run a validated virtual wind tunnel — streamlines, pressure fields, lift and drag — all in your browser.

In-browser 3D Viewer: WebGL viewer that renders STL, OBJ, STEP, IGES, GLB, and FBX with orbit, wireframe, transparency, bounding box, and measurement tools.
Virtual Wind Tunnel: Animated streamlines, velocity vectors, pressure and velocity contours, vorticity, wake, and flow separation rendered live during the solve.
Full Flow Setup: Configure speed, direction, density, temperature, pressure, humidity, altitude, fluid, and turbulence model per run.
Engineering Results: Reports Cl, Cd, Cm, Reynolds, Mach, forces, centre of pressure, and surface maps — exportable to CSV and PDF.
Interactive Charts: Lift-vs-angle, drag-vs-speed, pressure and velocity histograms, plus residual convergence and mesh statistics.
Comparison Tool: Overlay two runs side by side and read a performance difference table across pressure and airflow.
AI Aero Assistant: Explains flow separation, high drag causes, and suggests design changes; can run on the user's own Claude key.
Validated OpenFOAM Backend: Parallel snappyHexMesh + simpleFoam in Docker, benchmarked to within about 10% of published wind-tunnel data.

Airfoil analysis: Study Cl, Cd, and stall behaviour on airfoils like NACA 0012 without booking a physical wind tunnel.
Drone frame optimisation: Simulate flow around quadcopter and drone frames to reduce drag and improve efficiency.
Automotive aerodynamics: Rapidly iterate on car body geometries and read off aero coefficients before CAD sign-off.
Rapid design iteration: Compare two design variants side-by-side and quantify aerodynamic improvements.
Teaching and demos: Run browser-based aerodynamics demonstrations without installing OpenFOAM locally.
BYO compute: Point Ventorah at a user's own OpenFOAM worker and Claude API key for private, unlimited runs.

AI visibility platform that tracks how ChatGPT, Perplexity, Claude, Gemini and AI Overviews cite your brand, and ships fixes.

AI Citation Tracking: Continuously samples roughly 50,000 prompts per week across ChatGPT, Claude, Perplexity, Gemini and Google AI Overviews to record where and how a brand is cited.
Per-Engine Visibility Scoring: Reports a composite AI Visibility score plus share of voice and prompts won or lost, broken out engine by engine so declines can be traced to a specific model.
Prompts & Citations Explorer: Lets teams open any tracked prompt and read the actual model answer to see which competitor was named and why.
Brand Entity Analysis: Maps the adjectives each engine associates with your brand versus competitors and suggests reframing plays to change that portrait.
Competitor Intelligence: Tracks rival citation share on comparison and 'alternatives to' prompts, highlighting categories where a competitor dominates.
Prioritized Action Plan: Converts findings into P0/P1 recommendations such as schema additions or comparison pages, each with a time estimate and projected score gain.
Site Audit for AI Parseability: Audits pages for missing entity definitions, structured Q&A data and other signals that prevent models from citing the site correctly.
White-Label Reporting and API: Higher tiers add white-label client reports, SSO/SAML and API access for agencies managing multiple brands.

AI Search Monitoring: Marketing teams track whether ChatGPT and Perplexity recommend their product or a competitor on high-intent category prompts.
Competitive Benchmarking: Brands quantify how much citation share a named rival is capturing on 'alternatives to' and 'best of' queries.
Content Prioritization: Content teams decide which pages to write or refresh based on which prompts are currently missed rather than on keyword volume alone.
Technical AEO Audits: SEO specialists find pages lacking FAQ schema or entity markers that keep answer engines from parsing them.
Agency Client Reporting: Agencies run pooled prompt tracking across multiple client workspaces and deliver white-label AI visibility reports.
Executive Reporting: Operators present a weekly digest showing search clicks alongside AI citation share to explain traffic shifts leadership sees.
