Tabchat AI

Tabchat AI is built around a simple observation: most people lose time not because they cannot find information, but because the information they already found is scattered across dozens of open tabs. The extension lives in the browser toolbar, so when you land on an article, a report, a price table, or a dashboard, you can open a side conversation with that specific page instead of switching context to a standalone chatbot and pasting fragments of it back and forth.

The underlying model is Amazon Nova Pro, chosen for its roughly 300k-token context window. That matters in practice because it lets Tabchat consider a whole long document or a dense page at once, which reduces the chunking and re-prompting that normally breaks multi-step research. Alongside conversational Q&A, the extension includes a data extraction mode that reshapes messy page content into clean CSV or JSON, plus summarization for people who need the gist of a long piece quickly.

It is aimed at researchers, analysts, students, and anyone who reads for a living. The distribution model is a paid Chrome extension with a 14-day trial and a promotional subscription price that works out to roughly a few dollars per month, so it competes more on workflow convenience than on being a free utility.
