The project
Cosmic Cassy brings hundreds of organizations into one place that families can trust: help with bills, lodging, travel, food, school, medical care and emotional support, across all 50 states. Version 3 adds an AI engine that reads each organization’s own website and pulls out who qualifies, what they give and how to apply, with a source for every fact and a person approving it. It also adds Cassy, a guide that asks what your family needs and explains why each program fits, plus workspaces for organizations and social workers. All of it is in English and Spanish.
Cassy, the AI guide
Families describe their situation in their own words. Cassy asks a couple of follow-up questions, searches, and sorts programs into Strong fit, Worth checking and Related, each with a plain-language reason.
Resource profiles
At a glance, eligibility, available assistance, how to apply step by step, documents and forms, and Sources & Verification with the date the facts were last checked.
AI enrichment engine
Crawls each organization’s site politely, extracts facts with a verbatim quote and source, verifies them, and queues them for human approval. It costs about a fifth of a cent per site.
For organizations
Claim your listing, post notices, add programs, contacts and PDF documents, and see Insights. Sensitive changes wait for approval.
Care team hub
A verified workspace for social workers and nurse navigators: search, compare, and build resource packets as a link or PDF in English or Spanish.
Trust & community
Helpful votes, suggested corrections, discussion, saved lists and push alerts when a saved organization posts a notice.

Under the hood
Built with
- Node.js
- Express
- MongoDB
- Claude (Haiku/Sonnet) + Ollama
- Vector search
- AWS S3
- Web Push
- Google sign-in
- PWA
Built for trust: AI never overwrites human-verified data, every fact links to its source, and risky changes need approval. The crawler identifies itself honestly, respects robots.txt and blocks server-side request forgery on every redirect. Search blends embeddings with keyword fallbacks that understand location. The screens below are version 3.0, which launches soon, running locally on a copy of the public directory data.
