This is a submission for Weekend Challenge: Generosity Edition
What I Built
The Generosity Matchmaker Voice is an interactive, multi-modal web application designed to bridge the gap between people wanting to give back (donating items, books, clothes, or volunteer time) and local charities or community organizations. Instead of wondering how or where to contribute, users input what they have or want to do, and the app instantly structures a custom action planโcomplete with verified platform search terms, an accessible audio voice guide, lightning-fast Solana micro-donations via scannable QR codes, and cloud impact logging powered by Snowflake.

An AI-powered community giving and charity companion built for the DEV Weekend Challenge: Generosity Edition.
๐ About The Project
The Generosity Matchmaker is a lightweight, interactive web application designed to bridge the gap between people wanting to give back (donating items, books, clothes, or volunteer time) and local charities or community organizations. Instead of wondering how or where to contribute, users input what they have or want to do, and the app instantly generates a custom action planโcomplete with verified platform search terms, an audio voice narration guide, lightning-fast Solana micro-donations, and secure impact tracking analytics via Snowflake.

-
Google GenAI SDK (
gemini-2.5-flash) (for fast, structured natural language generation) - ElevenLabs API (for accessible, human-like voice synthesis and audio guides)

How I Built It
How I Used Google AI (Gemini), ElevenLabs, Solana & Snowflake
To power this application, the project integrates the Google GenAI SDK using the gemini-2.5-flash model, the ElevenLabs API for text-to-speech voice synthesis, Solana with Python-QRcode for instant web3 micro-donations, and Snowflake for secure cloud data warehousing and impact tracking analytics.
The AI & Data Workflow
When a user submits their donation intent, the app executes a multi-step pipeline:
-
Intelligent Matching & Platform Sourcing: Gemini processes the user's input to dynamically generate:
- The Target Charity Category: Identifying the exact cause domain (e.g., Education, Warmth Drives, Food Security).
- Actionable Preparation Steps: Clear checklists on sorting, packing, or organizing contributions.
- Suggested Platforms & Search Terms: Verified organizations, platforms, or search queries to help users find active local drives and direct donation links.
- A Polished Outreach Draft: A professional template that users can instantly copy-paste to email or message local non-profits.
Multi-Modal Voice Narration: Using the
st.session_statepersistence layer, the generated action plan feeds seamlessly into the ElevenLabs API, allowing users to generate and listen to an audio narration guide of their complete generosity plan.Web3 Micro-Donations & QR Code Integration: Users can support community initiatives with low-fee ($0.00025) crypto contributions by instantly scanning the dynamically generated Solana QR code with a wallet like Phantom or Solflare.
Cloud Analytics Logging (Snowflake): Every user contribution and match category is securely recorded into a Snowflake cloud data warehouse table (
generosity_logs), enabling data-driven insights and impact tracking.

How It Works
- Step 1: Open the live app link and navigate to the clean Streamlit interface.
- Step 2: Enter your donation or volunteering idea in the text area (e.g., "I have 3 boxes of English storybooks to give away").
- Step 3: Click "Find Match & Generate Guide โจ" to receive your tailored plan and search terms instantly.
- Step 4: Click "๐ Generate & Play Voice Guide" to hear your complete action plan read aloud via ElevenLabs voice synthesis for seamless accessibility!
- Step 5: Scan the Solana QR code using a wallet like Phantom or Solflare to support community initiatives with lightning-fast, ultra-low-fee micro-donations.

Nice. but if you add a system prompt of donation link , it will be better.
Thank you! I totally agree about making it as actionable as possible. I've updated the prompt to pull in specific search terms and verified platform categories so users know exactly where to go next, alongside the new voice narration feature. Thanks for checking it out!
Great use of Google AI! How did you handle the API rate limits in your workflow?
