The Challenge

Citations for an AI Assistant

A popular AI writing assistant wanted to differentiate in the crowded productivity market by solving research needs for students, professionals, and writers. They faced key obstacles:

Citation friction: Users abandoned writing flow to manually search for, verify, and format citations from academic sources, killing productivity.

Accuracy concerns: Without integrated verification, users couldn't ensure citations were from reputable, peer-reviewed sources.

Educational market barriers: Schools hesitated to adopt AI writing tools that couldn't reliably connect to verified academic research.

The Solution

Real-time citation engine

The platform built a real-time citation engine that seamlessly integrates academic research discovery and citation formatting into the writing workflow, powered by Exa's search endpoint with neural search.

Working with Exa's API, the writing assistant created:

Contextual Citation Suggestions: Semantic analysis of user text intelligently suggests relevant academic citations while writing, without requiring explicit searches.

Live Content Extraction: Real-time extraction of academic paper content to find the best quotes for users to directly cite in their writing.

What's under the hood?

Integrating Exa's search and snippets

The citation engine leverages Exa's Search endpoint to provide contextual academic research discovery. The system analyzes user writing in real-time and surfaces relevant academic sources without interrupting the creative flow.
