OpenAI's flagship multimodal assistant powered by GPT-6 and GPT-5.6 for reasoning, coding, and deep research.
Automatically routes prompts or lets users select between Instant responses and Medium, High, or Extra High thinking depth across GPT-5.6 Luna, GPT-5.6 Sol, and flagship GPT-6 Pro/Astra models.
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.

AI replies and email drafts that sound like you wrote them
The extension generates ready-to-send comments and posts for LinkedIn and X with a single click, cutting the blank-page problem out of social engagement.
Replies can be tuned by style, tone and length so the output matches how you want to come across in a given conversation.
Replai builds a personal profile from emails you share, capturing tone, phrasing and sign-off so drafts sound like you rather than like a template.
Connected inboxes are automatically sorted into categories such as Priority, Needs Reply, FYI and Unsubscribe.
