AssemblyAI Playground

Yes. AssemblyAI Playground is free (free (signed-in) / API billed).

AssemblyAI Playground runs in the browser, so it works on any desktop OS with a modern browser, and on phones and tablets.

There is nothing to install — AssemblyAI Playground is used in the browser. Create an account on the vendor's site and upload or connect your audio.

AssemblyAI Playground lists 99 languages. That is the Whisper-family multilingual set, so quality varies by language — English and the large European languages are strongest.

Audio uploaded for evaluation; API billing applies once exceeding free credits.

Developers evaluating AssemblyAI accuracy before integrating the API.

No. AssemblyAI Playground is a proprietary product. If you need source you can read and run yourself, the open-source tools in this directory are the place to look.

No — AssemblyAI Playground is browser-only. There is nothing to install and nothing runs on your machine.

In this directory AssemblyAI Playground is filed under playground, web app, developer as a product.

There is a side-by-side page at /tools/assemblyai-playground-alternatives comparing AssemblyAI Playground with the closest tools in the same category on price, platform and features.

Yes. If what you want is transcripts rather than the tool itself, Whipscribe does the same job as a hosted API: submit a file or URL, poll a job id, pull the result as txt, json, srt, vtt or docx. $0.008 a minute — about $0.48 an audio hour — bought as credits that never expire. The automation recipes on this site show it wired to Drive folders, Zoom recordings, S3 buckets and no-code platforms.

AssemblyAI Playground is another vendor's product; Whipscribe is a per-minute transcription service. We run the models on our own GPUs in a private cloud — audio is never forwarded to OpenAI or any third-party model — and every job returns five formats plus an AI summary, quotes and topics. Your first transcript in the web app is free at any length, no card.

$0.008 a minute — about $0.48 an audio hour — bought as credits that never expire. There is no subscription and no monthly minimum: a 3-hour recording is about $1.44, a thousand-hour archive is about $480 once. Your first transcript in the web app is free at any length, no card, so you can check accuracy on your own audio before paying anything.

Three things are moving across the whole speech-to-text market right now: summaries, action items and speaker insights generated on top of the transcript rather than sold separately; private, secured deployment where the audio never leaves a boundary you control; and agent access — transcription exposed as a tool that Claude, Cursor or a workflow runner can call directly. Whipscribe ships all three today: per-job insights, our own GPUs, and an MCP server.
