Specification

<https://webmachinelearning.github.io/writing-assistance-apis/#summarizer-api>
Summary
The Summarizer API can convert long input text to more
concise text, or recapitulate input text with various
requested options, such as text length, format and/or type.
Developers may use this API to provide a summary of news
articles, reviews or blog posts.

Risks
Interoperability and Compatibility
This feature, like all built-in AI features, has inherent
interoperability risks due to the use of AI models whose
behavior is not fully specified. See some general discussion
in https://www.w3.org/reports/ai-web-impact/#interop
<https://www.w3.org/reports/ai-web-impact/#interop>.
By providing a high-level API with clear output formats, as
well as a capabilities API for detecting what a given browser
supports, we believe we can guide web developers toward using
the API in an interoperable way that does not depend on the
specific models that a given browser or browser version uses.
Gecko: Defer
(https://github.com/mozilla/standards-positions/issues/1067
<https://github.com/mozilla/standards-positions/issues/1067>)
There was a request to comment when these features were moving
to the I2S stage - can we do to see if Mozilla is ready to
give a position?
Yes, we've given the intent to ship status update:
https://github.com/mozilla/standards-positions/issues/1067
WebKit: No signal
(https://github.com/WebKit/standards-positions/issues/393
<https://github.com/WebKit/standards-positions/issues/393>)
Web developers: Positive
(https://github.com/WICG/proposals/issues/163
<https://github.com/WICG/proposals/issues/163>)
Origin Trial signups have been 5x higher than what we see
from typical Origin Trials, suggesting a lot of developer and
partner interest. The survey conducted during the Origin
Trial, in February 2025, shows positive quantitative feedback
[1], and third-party partners have utilized the API for
various use cases [2] [3].
Do you have any qualitative feedback from the OT to share, in
particular around the API shape or platform availability
limitations (i.e., has anyone given any feedback on the
desktop-only nature of these APIs)?
Platform availability wise, several partners have asked for mobile
support, which is something we hope to fulfill in future
iterations, when possible.
Ergonomics wise, nothing in particular, partners seem to like the
API (also reflected in the scores we got via the readiness
survey[1]).

Other signals:
Activation
This feature would definitely benefit from having polyfills,
backed by any of: cloud services, lazily-loaded client-side
models using WebGPU, or the web developer's own server. We
anticipate seeing an ecosystem of such polyfills grow as more
developers adopt this API.
WebView application risks
Does this intent deprecate or change behavior of existing
APIs, such that it has potentially high risk for Android
WebView-based applications?
None
Debuggability
It is possible that giving DevTools more insight into the
nondeterministic states of the model, e.g. random seeds,
could help with debugging. See related discussion at
https://github.com/webmachinelearning/prompt-api/issues/9
<https://github.com/webmachinelearning/prompt-api/issues/9>.
Will this feature be supported on all six Blink
platforms (Windows, Mac, Linux, ChromeOS, Android,
and Android WebView)?
No
Not all platforms will come with a language model. In
particular, the initial launch focuses on Windows, Mac, and
Linux.
Is this feature fully tested by web-platform-tests
<https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>?
No
We have added some web platform test coverage for this
feature
(https://wpt.fyi/results/ai/summarizer?label=experimental&label=master&aligned
<https://wpt.fyi/results/ai/summarizer?label=experimental&label=master&aligned>).
How much we are able to test beyond the surface API is
unclear, given the nondeterministic nature of the output. The
explainer discusses this in
https://github.com/WICG/writing-assistance-apis/blob/main/README.md#specifications-and-tests
