Overview
Keeps your chat synced and allows you to ask doubts separately, without affecting the main conversation.
SubSync transforms AI conversations into a multi-threaded thinking experience. Open a synced sidebar next to ChatGPT or Claude and explore tangents, definitions, and experiments—without derailing your core conversation. Now with Prompt Improver: refine and strengthen your prompts in one click before sending, so you ask clearer, sharper questions every time. Features include real-time sync, multi-provider support, prompt enhancement, markdown formatting, and automatic conversation saving. Boost clarity. Reduce friction. Keep your flow. Permissions notice: Host permissions are required so SubSync can read and structure user conversations on supported pages (https://chat.openai.com/*, https://claude.ai/*). The extension only accesses these pages when the user explicitly opens it. No information is stored or sent externally without user action.
