What to watch out for
This is not the official provider, so access to GPT-4o or Claude can change or disappear if the upstream terms shift. Because no login is required, treat the service as public: do not paste confidential documents, personal data, or credentials into the box. Free third-party endpoints also tend to add usage limits or advertising over time, so keep an official option in reserve for anything important, and verify answers before acting on them. For team use, agree on naming and editing conventions in advance to avoid version conflicts or duplicated work. Name and archive exported files consistently so you can find and reuse them, and keep a backup copy of key data. Save a backup of the original file before large batch jobs, and keep an exported copy of key results in case the page or service becomes temporarily unavailable.
