P&ID diagrams with AI.
Describe your process system and AI generates piping and instrumentation diagrams with standard symbols for valves, pumps, vessels, instruments, and process equipment.
Process engineering diagrams in seconds.
No more searching through symbol libraries. Describe your process system in plain language and AI generates complete P&ID diagrams with proper engineering symbols, instrument tags, and piping connections.

Describe your process, get a P&ID.
Tell AI about your process system: tanks, pumps, heat exchangers, control valves and instrumentation. It builds a complete P&ID with standard symbols, piping connections and instrument tags.

A complete P&ID symbol library.
AI matches standard P&ID symbols from a specialized icon pack. Every valve, pump, instrument and vessel uses engineering notation recognized across the industry.
- Valves and actuators. Gate, globe, ball, butterfly, check and control valves.
- Instruments. Temperature, pressure, flow and level transmitters and indicators.
- Vessels and tanks. Reactors, columns, drums, storage tanks and heat exchangers.
- Pumps and compressors. Centrifugal, positive displacement, blowers, fans.

Fully editable after generation.
Every AI P&ID is fully editable. Change equipment tags, rearrange piping routes, add or remove instruments and adjust control loops to match your process. Try another prompt to explore alternative system configurations.
- Edit tags and labels. Update instrument tags, equipment IDs and line numbers.
- Rearrange layout. Move equipment, adjust piping routes and resize vessels.
- Add and remove equipment. Insert more valves, instruments or piping as needed.

Part of your AI whiteboard.
P&ID diagrams live on your MockFlow board alongside mind maps, documents, spreadsheets, and other AI-powered components. Generate process diagrams, document designs, and collaborate with your engineering team, all in one place.
- AI components. Mind maps, documents, charts, tables and more on one canvas.
- Real time collaboration. Work together with your engineering team on the same whiteboard.

Use your own AI. No limits. No credits.
Connect MockFlow to your Claude or ChatGPT account through MCP or GPT Actions. Your API, your usage: generate unlimited P&ID diagrams without worrying about credits or restrictions.
How AI P&ID generation works.
From process description to engineering diagram in three steps.
Describe your process
Type your process system, equipment and instrumentation needs. AI understands engineering terminology.
AI creates the P&ID
AI draws proper P&ID symbols, piping connections, instrument tags and equipment labels.
Refine and export
Edit symbols, adjust piping routes or try another prompt. Export as PNG or SVG, or share with your team.
P&IDs for every industry.
From chemical plants to water treatment, AI creates the right P&ID.
Chemical processing
Reactor systems, distillation columns and chemical mixing processes with proper safety instrumentation.
Water treatment
Filtration systems, chlorination processes and water distribution networks with flow control.
Oil and gas
Separation processes, compression systems and pipeline diagrams with industry standard symbols.
HVAC systems
Heating, ventilation and cooling systems with proper ductwork, valves and control loops.
Food and beverage
Clean in place systems, pasteurization processes and packaging line diagrams.
Pharmaceutical
Batch processing, sterile systems and purification processes with proper instrumentation.
