Having Notion-style writing tools on any random web page is super handy.
Being able to swap between Claude and ChatGPT in the sidebar is great.
UI can feel a bit cluttered when reading dense sites.
Open source goodness.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Summarize, analyze or rewrite text directly on the website you are reading, not only inside Notion.
Route prompts through Notion AI, ChatGPT Web, ChatGPT API, Bard, Bing, Google AI or Claude depending on what you have access to.
All of Notion AI's built-in prompts are available, so familiar actions work the same way outside Notion.
Save your own reusable prompts for recurring tasks like tone edits or structured summaries.
Answers render as they arrive, so long outputs start appearing immediately instead of after a pause.
NotionAI Plus takes the handy inline AI actions people know from Notion and decouples them from Notion itself. Once installed, the extension adds a sidebar to ordinary web pages and lets you run prompts over whatever text you have selected or are reading: generate a summary, analyze a passage, or judge the sentiment of a review thread.
A distinctive part of the design is the pluggable backend. Instead of locking you to one model provider, the extension can send requests through Notion AI, ChatGPT's web interface, the ChatGPT API, Google Bard, Bing, Google AI or Claude. That makes it a thin, flexible front end you can point at whichever service you already pay for or have access to.
The extension also mirrors Notion's own prompt library and lets you save custom prompts, with streamed responses so answers appear as they are produced. It is published under the MIT License with source on GitHub, and it stays deliberately lightweight — the extension itself collects no data, since your content goes to whichever AI provider you configure.
Pull a quick summary or key points from a dense paper, report or news piece without leaving the tab.
Run selection-based prompts to tighten phrasing, change tone or restructure a paragraph in place.
Scan reviews, forums or feedback threads and get a fast read on whether the tone is positive or negative.
Build and fork the MIT-licensed extension, swapping in the model provider and prompts your workflow needs.
