Your research assistant
Give Codex the files, notes, data, decisions, and code behind the task. It works from the actual materials that shape the job, so you do not have to flatten real work into a single prompt.
Screen showing a text box with the prompt to use Gmail, Google Drive, and Slack to investigate wholesale order shipping delays, summarize root cause, impacted customers, inventory issues, and recommended fixes. Background shows a partial document titled "Investigation Summary: Wholesale Order Shipping Delays" with details on contributors and estimated impact.
Get finished work back

Make good work repeatable
For work you do again and again, Codex can gather the latest context from GitHub, Slack, and docs, then help turn proven workflows into updates, summaries, follow-ups, automations, and code changes.
A task list with three sections: Up next shows four tasks with statuses and start times; Unread shows two tasks marked with blue dots and recent times; Read shows two completed tasks with checkmarks and days since done.
For the work teams do every day
Use Codex for KPI readouts, pipeline updates, finance reviews, launch briefs, renewal prep, recruiting packets, customer summaries, bug triage, prototype builds, and follow-ups.
Text on a digital interface showing a weekly report titled "Team Update". A message bubble says, "That’s exactly what I wanted for this weekly report. Can you create an automation that does what we just finished every week at 4pm on Thursdays?" The interface includes options for GPT-5.5 and a microphone icon, suggesting AI-assisted report generation.
You stay in control
Codex shows the sources, assumptions, changes, and next steps so teams can review, refine, and decide what happens next.
