Data analytics tool using LLMs with a focus on data privacy and ease of use.
VerbaGPT is a tool designed to make data analytics using large language models (LLMs) easy and private. It allows users to ask questions of their SQL data, CSVs, or personal notes in natural language and receive answers. VerbaGPT runs locally, ensuring data privacy by not giving the LLM direct access to the data itself, only the schema and explicitly provided information.
AI-powered platform for streamlining software project scoping and generating project scopes.
Scopilot is an AI-powered platform streamlining the software project scoping process. It helps users quickly generate comprehensive project scopes by producing feature sets, user stories, and clarification questions based on a given project description. It assists software agencies and product companies with software scoping and product requirements, accelerating product definition and helping with product discovery and specification.
Diagram-to-code platform transforming validated backend architectures into deterministic code.
Solarch is a diagram-to-code backend architecture platform powered by a strict, default-deny rules engine. It turns backend architecture into a live node and edge graph, validating structural connections as they are drawn to eliminate architectural drift. Once validated against canonical design patterns through GraphRAG and LangGraph, the platform uses a hybrid code engine to compile the graph into a deterministic skeleton with zero tokens before leveraging a surgical AI to fill empty function bodies. This guarantees type-safe development from the database schema up to the user interface contract.
