Heliciel discovery pass

Heliciel in ChatGPT: the computed propeller, in 3D, inside the conversation
Heliciel in your assistant: the computed propeller, in 3D, inside the conversation (interactive view in ChatGPT; image and link elsewhere).

Heliciel on Demand works from the AI assistant you already use — ChatGPT, Claude, Le Chat and most others. You describe what you need, the assistant drives the Heliciel software on our servers and returns computed results, never estimates: thrust, torque, power, efficiency, cavitation, 3D views. Nothing to install.

To try it you need a pass key. The discovery pass is free and is requested below, with no customer account.

 The discovery pass

What it gives: every design, analysis, optimisation and visualisation tool of the service, for 1 days, with 60 minutes of Heliciel instance time.

Instance minutes: not a number of computations, but the time during which a Heliciel instance is reserved for you, from the first tool called in a conversation until it is released after inactivity. A typical working session uses fifteen to thirty: enough to design a propeller, compare two variants and see it in 3D. A session in progress is never cut.

What it does not give: 3D file exports (STL, IGES, OBJ, GLB) and table exports, which need a paid pass. The assistant will tell you so if you ask for one.

Once per address: the key is sent by e-mail after your address is confirmed. It is not renewed.

How it works, in three steps:

   

A ChatGPT conversation with the Heliciel plugin: tool call, propeller in 3D, blade profiles

1. You receive your key by e-mail.

2. In ChatGPT, install the Heliciel Propeller Design plugin from the plugin directory; in Claude, the Heliciel connector from the connectors directory; elsewhere, add a connector (or “MCP server”) at https://mcp.heliciel.com/mcp.

3. On first connection a Heliciel page asks for your key: paste it, then describe your need to the assistant. The first answer can take up to two and a half minutes if an instance has to start. Detailed instructions, assistant by assistant.

 

After the discovery pass: pass durations

   

The Heliciel pass is bought for a number of days, from one day to several weeks, at a per-day rate that decreases with the duration. It is prepaid: it has an end date, stops by itself, and never triggers a renewal payment. The day count only starts when you start the pass from your customer area, not at purchase. While valid it has no minute cap and opens every export.

For regular use, the Heliciel licence installed on your computer remains the better deal: no time limit, free updates, and the same AI-assistant control, locally.
