# Research brief: choose where to try one file task

Synthetic decision context. The products and linked documentation are real; the team and constraints below are fictional. This brief does not grant account or file access.

A fictional operations coordinator needs an editable weekly update from a supplied tracker and meeting notes. Compare ChatGPT Work and Claude Cowork for a first supervised attempt. The coordinator has not confirmed either product’s eligibility, file permissions or editable output support.

Criteria: can read the two authorized files, save inspectable editable output, retain source/exception notes, and finish without sending or sharing. No subscription budget or preferred provider is known. Do not assume either account is eligible or buy anything.

Read the supplied [primary-source notes](source-notes.md), observed 23 October 2026. If browsing is available, refresh the two pages before relying on current availability. If browsing is unavailable, use the dated notes and distinguish documented support at that date from current, unchecked account conditions.
