Reddit Persona Generator

Built for the AI/LLM Engineer Internship Assignment @ BeyondChats

A fully local, end-to-end pipeline to transform real Reddit activity into structured user personas — using Reddit API, Python, and the Mistral LLM running via Ollama.

---

📖 Project Description

Imagine being able to understand any user deeply — just by reading how they talk online.

Reddit Persona Generator does exactly that.
It takes a Reddit profile, scrapes public posts/comments, and uses a local LLM to generate a structured persona — complete with:

• Behavior patterns
• Frustrations
• Goals
• Motivations
• Tone
• Interests

…and even citations for every insight from real Reddit activity.

💡 Why This Project Matters

LLMs are powerful — but without real-world grounding, they're just words.
This project shows how LLMs can extract genuine human insight from everyday conversations online — for use cases like:

• Personalized marketing
• User segmentation
• Behavioral analysis
• Agent customization

And the best part? It runs entirely offline, using Mistral with Ollama.

Processed Reddit Users

Reddit Username	Persona Type
kojied	Urban, reflective tech worker
Hungry-Move-6603	Civic voice, realism, political concern
St0rmCh4ser	Tech & crypto guide
drywallwizard	DIY expert, knowledge sharer

⚠️ Invalid Profile Handling

The script gracefully exits if a profile doesn't exist or has no data:

Error fetching data for MasterOfNone_92: received 404 HTTP response
No data found. Skipping persona generation.
