+# Buddy - Indic Language AI Assistant
+
+## 1. AI Assistant Overview
+
+**Assistant Name:** Buddy  
+**Purpose & Target Audience:**  
+Buddy is a friendly, multilingual student assistant designed to help Indian students in **Telugu, Hindi, and English**. Its primary aim is to make access to academic help, doubt solving, and general knowledge easier for Indic language speakers.
+
+**Key Features:**
+- Multilingual support: Telugu, Hindi, and English
+- Simple, polite responses tailored for students
+- Runs efficiently in a local/low-resource setup
+- Feedback capture for continuous improvement
+- Downloadable chat history
+- Support for factual Q&A and general conversation
+
+---
+
+## 2. System Prompt Design and Justification
+
+### Chosen Open-Source LLM & Environment
+
+**LLM:** [`ai4bharat/IndicBART`](https://huggingface.co/ai4bharat/IndicBART)  
+**Deployment/Interaction Environment:**  
+We use a **local Python + Streamlit** setup. The `transformers` library loads the model for real-time inference. This ensures the app is free to run without API call costs, and it is truly open-source in both model and hosting.
+
+### Full System Prompt
+
+
+### Prompt Justification & Impact
+
+- **Persona:** The assistant is named “Buddy” to create a student-friendly, non-intimidating experience.
+- **Tone:** Polite and simple answers ensure accessibility for younger students and non-native English speakers.
+- **Language Handling:** The prompt ensures support for three major Indian languages. IndicBART handles translation and generation reasonably well.
+- **Constraints:** No long or verbose responses. Keeps clarity as priority.
+
+### Iteration:
+We modified decoding logic:
+- Use **beam search** for short queries to reduce randomness.
+- Allow sampling for longer or open-ended queries.
+
+This change significantly reduced hallucinations like repetitive or nonsensical answers to factual questions.
+
+---
+
+## 3. User Reviews and Feedback Analysis
+
+**Feedback Collection Plan:**  
+We collected user feedback through a feedback form inside the app (`feedback.csv`).
+
+| User ID | Date | Language | Purpose | Rating | Comment |
+|---------|------|----------|---------|--------|---------|
+| student_01 | 2025-08-02 | Hindi | GK question | 4 | “Good answer, slightly slow” |
+| student_02 | 2025-08-02 | Telugu | Basic doubt | 5 | “Understood everything!” |
+
+### Summary:
+- **Accuracy:** 80% of queries were correctly answered
+- **Clarity:** Very high for simple questions
+- **Tone:** Polite and respectful
+- **Issues Found:** Struggled with basic math and string repetition in factual queries like “What is 2 + 3?”
+
+### Key Improvements Identified:
+1. Improve math/factual grounding
+2. Add fallback messages for unknown queries
+3. Add a clearer language switch indicator
+
+---
+
+## 4. Future Roadmap
+
+### Short-Term Goals (1 Week)
+- Add math parsing for small arithmetic
+- Improve clarity on language selection
+- Polish the UI further with icons and speech-to-text
+
+### Mid-Term Goals (2–4 Weeks)
+- Add new Indic languages (e.g., Bengali, Marathi)
+- Add RAG capability using `faiss` or custom datasets
+- Allow voice input using `whisper` or `VOSK`
+
+### Long-Term Vision (1+ Month)
+- Make Buddy usable by rural students via mobile
+- Build an offline APK using Streamlit’s mobile compatibility or Toga/Beeware
+- Create learning pathways in Indian languages using Buddy
+
+---
+
+## 5. Plan to Increase User Adoption
+
+### Acquisition:
+- Share public repo on GitHub and Hugging Face Spaces
+- Promote in regional student forums and Telegram groups
+- Present to local colleges as free learning help
+
+### Promotion:
+- Tag as “Indic Learning Assistant” on GitHub
+- Write blogs/tutorials on building open-source chatbots
+
+### Feedback Loops:
+- In-built feedback with CSV logging
+- Future integration with Google Sheets for faster aggregation
+
+### Community Growth:
+- Accept community language patches via GitHub
+- Encourage user testing in different dialects
+- Collaborate with NGOs supporting education in regional languages
