A side-by-side comparison of Assistly and Ventorah — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.

Assistly

Freemium

A live meeting assistant for Mac and Windows that reads call audio locally and shows guidance in an overlay excluded from screen shares.

Bot-Free System Audio Capture: Works from your computer's audio rather than joining the meeting, so nothing appears in the participant list and there is nothing to integrate with the call app.
Screen-Capture-Excluded Overlay: The assistant window is excluded from screen capture at the OS level, so it stays visible to you and invisible in shares and recordings.
Auto-Assist Without Prompting: Detects when a question lands or when you think out loud and streams structured talking points into your thread automatically, with no hotkey and no break in eye contact.
Multi-Speaker Language Tracking: Separates your voice from other participants and follows who said what across dozens of auto-detected languages, even when the call switches language mid-sentence.
Two-Way MCP Context: Pulls context from Google Calendar, Notion, Linear or any MCP server during the call, and exposes your meeting history back over MCP so Claude, ChatGPT or Cursor can query it later.
Personas from Your Material: Builds a persona from your CV, docs and notes and switches modes for a sales call, client review or interview so responses match your background and phrasing.
Automatic Recap and Action Items: Turns the transcript into a summary with owners and deadlines the moment the call ends, auto-saved and searchable across sessions.
Per-Client Projects: Files each session to a project based on the calendar, and scopes answers and mid-call lookups to that client's history so context never crosses between accounts.

Live Sales Calls: Surfacing objection handling and product detail the instant a prospect asks, without breaking eye contact to search a doc.
Client Account Reviews: Recalling what was committed to a specific client in a previous session, with the source call cited, while the review is still running.
Non-Native Language Meetings: Following a call that switches language mid-sentence and receiving guidance in clear English.
Customer Success Handoffs: Leaving every call with a written summary and assigned action items instead of reconstructing notes afterwards.
Meetings Where Bots Are Unwelcome: Getting live assistance on calls with clients or legal teams who object to a recording bot joining the room.
Querying Past Meetings from Your Editor: Asking Claude, ChatGPT or Cursor what was agreed in a past session over MCP without opening the app.

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.
