AI-powered synthetic biology IDE

Design genetic circuits with AI

Describe what you want in plain English. Nuclex finds the right parts, assembles your circuit, validates biosafety, and exports to Benchling in minutes.

Free to use. No credit card required. Guests get 2 AI credits, no sign-up needed.

Terminator

Promoter → RBS → CDS → Terminator — the building blocks of every genetic circuit

How It Works

Go from an idea to an exportable genetic circuit in three steps.

Describe Your Circuit

Type what you need in plain English: "Design a bacteria that produces GFP when exposed to IPTG."

AI Assembles & Validates

AI parses your intent, retrieves matching parts from our curated database, and assembles a validated circuit.

Export & Order

Export as GenBank, SBOL, or FASTA. Get synthesis quotes and order from Twist or IDT.

Everything You Need

A complete toolkit for designing, validating, and exporting genetic circuits.

AI-Powered Design

Natural language to genetic circuit in seconds. AI handles intent parsing, part selection, and circuit assembly.

Curated Parts Database

Thousands of parts from iGEM, NCBI, and AddGene with semantic search. Promoters, RBS, CDS, terminators, and more.

Biosafety & Validation

Every design is screened for biosafety. Five biological checks catch codon issues, restriction conflicts, and metabolic burden.

Visual Circuit Editor

Drag-and-drop SBOL-standard glyphs. Auto-layout, undo/redo, backbone selection, and 15+ starter templates.

Lab-Ready Export

Export GenBank, SBOL, or FASTA. Pick a backbone for full plasmid maps. Auto-generate PCR, Gibson, and Golden Gate primers.

Synthesis Ordering

Get estimated quotes from Twist and IDT. Complexity screening and biosafety gate before you order.
