PROMPT
Users own their inputs and generated outputs. "Both Input and Output are considered User Content under these Terms, and as between you and Descript, you own all right, title, and interest in and to any Input and Output, to the extent protectable under applicable law."
OUTPUT
Users own their generated outputs but Descript notes that "the copyright status of the generated Output may not be clear and that the use of such Generative Tools may affect your ability to obtain or enforce any intellectual property rights."
TRAINING
Descript uses content to train models by default unless the user opts out. "Descript may access and use your Input and Output in order to create and operate Descript...including by Descript to train, improve, and develop its models and technologies (unless you have opted out of such use)."
COMMERCIAL
Commercial use of user-generated outputs is permitted. Specific commercial licensing applies to Storyblocks stock material.

WORKFLOW & AUTOMATION
PROMPT
Microsoft does not claim ownership of customer prompts or inputs. Customer data remains customer property under Microsoft's data governance framework.
OUTPUT
Microsoft doesn't claim ownership of the output of the service. Outputs are treated as customer data.
TRAINING
Microsoft does not use M365 Copilot customer content to train foundation models. The Microsoft Privacy Statement (March 2026) states for enterprise Copilot: 'Microsoft 365 Copilot...provides enterprise-grade data protection' and 'will use the content in your files only when you ask it to perform a specific action on that specific content.' General Microsoft AI statement covers manual review of automated method outputs for improving accuracy, but enterprise Copilot data is explicitly protected.
COMMERCIAL
Microsoft 365 Copilot is available as an enterprise add-on. Commercial use of all outputs is permitted.

“We claim no ownership rights in your User Content. You hereby grant to us a perpetual, irrevocable, nonexclusive, royalty-free, sublicensable, fully paid, worldwide license to create derivative works from, access, reproduce, distribute, process, publish, display, perform, adapt,…”
Despite claiming no ownership, Descript takes an extremely broad, perpetual, irrevocable, sublicensable license over all user content including name and likeness, across all current and future media channels, with no compensation.

Descript disclaims ownership of user content but takes back a sweeping perpetual, irrevocable license to outputs/edited content. The scope of 'improve the Descript Service' is broad and could encompass model training.

The license to 'analyze' and 'improve the Descript Service' could encompass AI model training on user content. There is no explicit opt-out mechanism referenced in the visible text.
Microsoft 365 Copilot
HIGH⚠ CAUTIONHIGH
Microsoft does not use M365 Copilot customer content to train foundation models. The Microsoft Privacy Statement (March 2026) states for enterprise Copilot: 'Microsoft 365 Copilot...provides enterprise-grade data protection' and 'will use the content in your files only when you ask it to perform a specific action on that specific content.' General Microsoft AI statement covers manual review of automated method outputs for improving accuracy, but enterprise Copilot data is explicitly protected.
“As part of our efforts to improve and develop our products, we may use your data to develop and train our AI models. Learn more here .”
Microsoft explicitly reserves the right to use user data to train AI models. This appears twice in the document, suggesting it applies broadly across products and tiers.

Commercial Use
Descript
HIGH⚠ CAUTIONHIGH
Commercial use of user-generated outputs is permitted. Specific commercial licensing applies to Storyblocks stock material.
“Additional content libraries (the “Additional Libraries”) are not subject to this license, may not be available for commercial use without a license, and may require that you obtain model clearance.”
Additional Libraries outside Storyblocks may require separate commercial licenses and model clearances, creating potential legal exposure for users who assume all platform content is commercially usable.
Microsoft 365 Copilot
HIGH⚠ CAUTIONHIGH
Microsoft 365 Copilot is available as an enterprise add-on. Commercial use of all outputs is permitted.
“The articles, text, photos, maps, videos, video players, and third-party material available on Bing and MSN, including through Microsoft bots, applications and programs, are for your noncommercial, personal use only. Other uses, including downloading, copying, or redistributing t…”
Bing and MSN content is restricted to noncommercial personal use. Using outputs/materials to build products or for commercial purposes requires explicit Microsoft authorization, which is not granted by default.

“Personalize and improve the Descript Service and for research and development purposes including training our artificial intelligence models;”
User data (including uploaded content) may be used to train AI models. An opt-out exists for Projects specifically, but this broad statement covers other collected information without a clear opt-out.
Microsoft 365 Copilot
HIGH⚠ CAUTIONHIGH
Enterprise/commercial M365 Copilot provides strong data protection — content not used for training, enterprise-grade compliance. Consumer Microsoft products (Bing, Cortana, etc.) have broader licenses. Bing Places grants a 'worldwide, royalty-free license to use, reproduce, save, modify, aggregate, promote, transmit, display, and distribute your Data and Your Content...and sub-license any or all of the foregoing rights to third parties.'
“If you fail to remove excess content or obtain sufficient additional storage after receiving notice from Microsoft, we reserve the right to delete or disable access to Your Content.”
Microsoft may permanently delete Outlook.com user content upon storage quota breach without a defined grace period in this clause.
