title: PosterLens
description: Turn static scientific posters into interactive research insights
---

## 🔍 What is PosterLens?

**PosterLens** is a mobile app that transforms static scientific posters into interactive, explorable insights using OCR and AI.

Created for the Perplexity Hackathon 2025, it allows researchers, MSLs, and medical writers to:

- Scan posters using device camera + Apple Vision OCR
- Ask natural-language questions about the content
- Find semantically related studies using **Sonar Pro**
- Auto-generate research questions & future directions
- Validate citations with PubMed E-utilities

## 🧠 How PosterLens Uses Sonar Pro

PosterLens integrates **Sonar Pro** for:
- Semantic understanding of OCR-extracted poster text
- Factual Q&A grounded in scientific literature
- Retrieval of related studies and citation-backed content

Sonar Pro is essential for turning a static scan into a dynamic research experience.
