Show HN: GrantFlow (FastAPI and LangGraph) for donor-aligned NGO proposal drafts (github.com)

GrantFlow has introduced a sophisticated proposal drafting engine tailored for NGOs and consulting organizations, leveraging FastAPI and LangGraph. Designed to streamline the creation of donor-aligned proposal artifacts, GrantFlow facilitates the conversion of structured project ideas into essential documents, including Theory of Change (ToC) and Logical Framework (LogFrame). The system incorporates critique loops, citations, and human-in-the-loop (HITL) checkpoints, significantly reducing the time and effort required to draft compliant proposals for institutional funding. This innovation is particularly significant for the AI/ML community as it employs a stateful graph pipeline to manage specialized drafting processes, ensuring quality and alignment with donor strategies from various institutions such as USAID and the World Bank. The inclusion of compliance-aware donor logic enhances its functionality by enabling tailored responses based on specific donor requirements. Users can interact with the API for various tasks, including proposal generation and exporting documents in multiple formats. GrantFlow not only optimizes the proposal drafting workflow but also incorporates advanced AI techniques to improve proposal quality through iterative feedback, establishing itself as a critical tool for organizations navigating complex funding landscapes.
