Audioscrape keeps searchable transcripts of oral arguments from the Supreme Court of the United States, back to the October 2010 term, and from state courts in California, Arizona and Arkansas: the Supreme Court of California, six divisions of the California Courts of Appeal, the Arizona Supreme Court, and the Arkansas Supreme Court and Court of Appeals. You can search every argument at once by what was said (a doctrine, a statute, a case name, a phrase), and each result links to that second in the recording, so you hear the exchange before you cite it. The same search works inside ChatGPT and Claude.
What is covered
As of 7 November 2026:
| Court | Arguments in the record | Since | Speaker names |
|---|---|---|---|
| Supreme Court of the United States | 1,060 | October 2010 | Justices and advocates named on much of the record (43% of passages) |
| Supreme Court of California | 17 | October 2025 | Partly (13%) |
| California Courts of Appeal: First, Fourth (Div. 1), Fourth (Div. 2), Fourth (Div. 3), Fifth, Sixth | 382 | September 2025 | Mostly not yet (0–2%) |
| Arizona Supreme Court | 17 | March 2026 | Partly (37%) |
| Arkansas Supreme Court and Court of Appeals | 21 | February 2026 | Partly (6–18%) |
New arguments are added as the courts publish their recordings. The full list is at /court.
How to search it
On the website. Type the words into search; each court’s page lists its arguments. Use quotes for an exact phrase ("qualified immunity"), and plain words or a question for the idea behind it. Each hit shows the court, the case, the date, the speaker where the transcript names one, and a link that opens the audio at that moment.
In ChatGPT or Claude. With Audioscrape installed (ChatGPT, Claude), ask “In Supreme Court arguments since 2020, when did the justices ask about the major questions doctrine? Link the moments.” The assistant searches the arguments and answers with the passages, the speakers and the links.
Get told about new arguments. Follow a court from its page to get an email when a new argument is transcribed, or set an alert on a search (“Alert me on new results”) to hear when a phrase is said in any new argument. Email alerts need no account. See Alerts.
What it is and what it is not
- It is a search tool for what was said. Finding the argument and the minute where a question came up takes seconds instead of listening through hours of audio.
- It is not the official transcript. The Supreme Court of the United States publishes official argument transcripts on its own website, and some state courts publish their recordings only. Audioscrape’s transcripts are machine-made: cite the official transcript or the recording, and use the link to check the words.
- Speaker names are machine labels. The table shows the share of passages tied to a named person. Where no name is attached, speakers are still separated. A name can be wrong; the linked audio settles it.
- Coverage is the courts listed above. Courts that are not listed are not searchable here yet.
Other places to look
For the US Supreme Court, the Court’s own website has the official transcripts and audio, and Oyez publishes argument audio with transcripts synced to it. Commercial legal research services cover written opinions and briefs in depth. Audioscrape is useful when you need to search across many arguments at once by what was said, with the moment linked, or want to ask an assistant to do it.
