This is a submission for the Hacktoberfest Open-Source AI Challenge Week 2: Side Hustle What I Built I built ContextBridge , a Chrome extension that helps you switch between AI models without losing the context of your work. Ever hit a usage limit while working on a project with ChatGPT, only to realize that switching to another AI means explaining everything all over again? ContextBridge solves…
ContextBridge is a Chrome extension created by Prathamesh2007-o7 to help users switch AI models without losing the context of their work. It was developed as part of the Hacktoberfest Open-Source AI Challenge Week 2, focusing on the theme of Side Hustle What I Built. The extension captures visible AI conversation messages from supported ChatGPT, Claude, and Gemini page layouts, using Ollama to run open-weight models like Gemma 3 (4B) for generating a structured continuation handoff.
This handoff covers key elements such as project state, decisions, constraints, failed attempts, blockers, and next steps. ContextBridge allows users to review, edit, copy, or export the handoff as Markdown, ensuring they can continue their work seamlessly with another AI model. By running inference locally through Ollama, ContextBridge minimizes reliance on paid cloud AI APIs, providing users with greater control over their conversation data and eliminating per-request charges.
The project exemplifies open innovation, leveraging open-weight AI through Ollama and making it easier for developers to build and customize tools that address practical challenges.
