Asynchronous software engineering and task agents that clone repositories, run terminal tests in sandboxed environments, resolve complex bugs, and submit pull requests.
Browses dozens of primary web sources, academic papers, and connected workspace documents over several minutes to compile structured, citation-backed analytical reports.
Provides a split-screen editor for inline prose and code revisions alongside low-latency voice conversations with live screen and camera grounding.

One-click AI summaries of any webpage from your Chrome sidebar
Press the sidebar button on any page and ReadSmart returns a condensed summary of the page's text without you scrolling through everything.
Rather than dumping the whole page into a summary box, the extension detects the main textual content, which works best on news sites and long-form blogs.
Summaries you have already generated are kept, so you can return to a page you read earlier and jump straight back into the gist.
The extension lives in the Chrome sidebar, so generating a summary never pulls you out of your current tab or workflow.
