Developer launches HighLights plugin for ChatGPT bookmarking and knowledge management

On 2026-11-02, an independent developer posted on V2EX about HighLights, a ChatGPT plugin built for highlighting and knowledge management. In the post, the developer explains that frequent use of ChatGPT for learning, research, and discussion made a recurring problem visible: after a topic has been explored in depth, the valuable questions, viewpoints, and conclusions that surfaced along the way become hard to retrieve. Reopening a long conversation means scrolling up and down through the transcript, even when the real prize is a handful of sentences rather than the whole exchange. The initial goal was straightforward: let ChatGPT conversations be annotated the way books are, so that worthwhile passages can be marked, saved locally, and revisited later.

What began as a single highlighting feature gradually grew into a notes tool. The developer describes adding a standalone workspace, notebook management, and data export, so that a user can collect, categorize, and comment on highlights after marking them, capturing the understanding and thinking at the moment of reading. The stated motivation for export is integration rather than isolation: highlights should be able to flow into knowledge management tools such as Obsidian and become part of a personal knowledge base instead of forming a new silo. As described, HighLights supports highlighting key passages inside conversations, local saving, organized classification through the independent workspace, and export to Obsidian.
