Draw the architecture; Solarch writes the code that matches it
Model the whole backend — controllers, services, repositories, tables, DTOs and queues — on one surface with 16 semantic edge types across 8 families.
An illegal connection such as wiring a controller straight to a table is rejected the instant you draw it, based on 7 anti-patterns and 3 conditional checks.
Stage one compiles the graph deterministically into skeletons with zero tokens; stage two uses surgical AI to fill only the empty function bodies.
A LangGraph-powered architect grounds every plan in a vector-indexed library of canonical patterns instead of autocompleting from scratch.

The collaborative whiteboard built for product builders
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.

A spec-driven AI IDE and agent platform that plans, builds, reviews, and verifies real engineering work.
Free / Open-sourceCombines mind mapping and project workflows with AI agents, but less focused on pure visual diagramming and wireframes.
AI diagrams and technical design docs built from your code and systems
Robust collaborative whiteboard with strong AI diagramming tools, but less polished UI wireframing capabilities than Whimsical.
Free / Open-sourceReactive TypeScript backend with database, functions and AI gateway

Agent orchestration platform for your whole software development lifecycle

Dedicated diagramming platform with strong AI chart generation, but less focus on freeform collaborative brainstorming whiteboards.
SpecialistInstantly turns natural language prompts into mind maps and flowcharts, but offers less freeform canvas drawing flexibility.
Combines whiteboarding and documentation with AI generation, but lacks Whimsical's specialized wireframe shape library.
Exceptional UI wireframing and prototyping tools, but less versatile for general mind mapping and freeform brainstorming.

SpecialistTransforms documents into strategic diagrams using AI, but less refined for everyday collaborative visual brainstorming.
