BioPath Sketch AI

Turn one sentence into editable, verifiable pathway diagrams without subscription lock-in

Problem

When immunology labs need a figure for group meeting, the same TCR proximal signaling diagram gets relabeled, expanded with checkpoints, and resized for journals. Editing an AI bitmap means redrawing, and subscription canvas files can't be taken away. Existing tools are either rented clipart libraries or expensive BioRender clones.

Solution

An AI scientific illustration tool that takes plain Chinese or English descriptions of cells, receptors, ligands and interactions, and outputs editable draw.io pathway diagrams. Each element carries bio_* semantics for verification, and SVG/PDF exports belong to the user for papers and slides.

Users

Lab researchers, postdocs and grad students in immunology and cell biology who frequently update figures for group meetings

MVP

Natural language to draw.io pathway generation; built-in templates for peptide-MHC, TCR-CD3, Lck/ZAP-70, LAT, PLC-gamma/Ca2+/MAPK components; bio_* semantic labels with a verification view; SVG/PDF export; version history and re-editing

Revenue

Monthly subscription for more templates, journal-size presets and team collaboration; or one-time export credits with annual lab licenses

Why now

LLMs now understand biological pathway semantics well enough, and draw.io is open and embeddable; an indie can build a moat with vertical templates rather than generic drawing
