TelesphorusQUILL

Describe the construct. Quill designs it.

Quill is Telesphorus's genetic design intelligence. Tell it what you want in plain English, and get back a synthesis-ready, validated construct.

The walkthrough below is an animated demo of a real Express run, from prompt to verdict, with the optimized sequence, the annotated plasmid map, and the biosecurity gate. It replays a recorded scenario; it does not compute live in your browser.

What lands on your bench

Not a drawing. Validated output, ready to order.

Optimized CDS

CAI-tuned, GC-compliant, synthesis-clean coding sequence.

GenBank plasmid

Annotated .gb that opens directly in your sequence editor.

PDF lab report

Decision-first: verdict, scorecard, plasmid map, decision tree.

Bench sheet

The protocol and parts list to take straight to the wet lab.

Design record

A full machine-readable .json: every decision, cited.

What Quill is · the Express flow

Eleven steps, one auditable flow.

AI handles the make-or-break judgment; deterministic engines do everything that has to be exactly right. The biosecurity gate is mandatory and never skipped.

Requirements parse

Plain English becomes a structured design: protein, host, expression level, tags, constraints.

Gene fetch

Curated registry → NCBI Entrez → UniProt fallback, with an LLM identity check that the gene matches the request.

Codon optimization

Simulated annealing balances CAI against organism-aware GC bounds, illegal sites and homopolymers. --harmonize for co-translational folding.

Regulatory design

Promoter, RBS and terminator selected from real parts, host-compatible by construction.

Assembly

The annotated plasmid is built, parts placed, provenance attached.

Structure check

A fast foldability heuristic in-loop; deep AlphaFold / ESMFold on demand.

4-layer validation

Sequence integrity, synthesis compliance, expression impact, biological sanity.

Biosecurity screen

commec (IBBIS) or a clearly-labelled synthetic fallback.MANDATORY GATE

Verdict

GO / CONDITIONAL / NO-GO, graded by real wet-lab expression impact, not a cosmetic score.

Auto-remediation

Fixable findings are re-run and re-screened (re-optimize, redesign RBS, reselect gene). Biosecurity blocks are never auto-fixed.

Deterministic export

No model. Exact field copy and arithmetic into .gb GenBank, .fasta, a .json design record, the PDF report and diagnostics, fully reproducible.

How Quill fits

A design layer, not a system of record.

Quill sits upstream of your ELN and sequence editor and feeds them. It proposes and ranks constructs from a goal, then hands off cleanly.

What Quill is not

  • An ELN / LIMS or system of record
  • A sequence-drawing tool you operate by hand
  • A black box (every claim is cited)
  • A lock-in: the data store is open-export

What Quill is

  • AI-native generative design that proposes & ranks
  • Synthesis-ready, validated, verdict-carrying output
  • GenBank that opens directly in the tools you already use
  • Open-export, with honest scope plainly stated

One product, a deep toolset

Express is the hero. These surround it.

Analyze

DNA linter, alignment & Sanger, primer QA, structure, maps and diff. Treat DNA like code.

Engineer

CRISPR editing, mutagenesis, cloning, fusions, libraries, multi-gene circuits. Instant & reproducible.

Predict

Off-target, on-target and yield, each with a confidence interval, a model name and grounded evidence.

Build & loop

Pareto optimization and an autonomous DBTL campaign agent with a human approval gate.

Workspace

Git-like version control, projects, an NL edit assistant and one-way ELN export.

Every tool, described

28 tools across six groups, with what each one does.

Where things stand

Honest about where we are.

Stage

A live beta, built by a student and getting better every week.

What it does

Turns a plain-English goal into a designed, checked construct. Fast.

Keep in mind

It's a design partner, not a replacement for the bench. Always confirm results in the lab.
