    Click Generate summary

    In the Summarize with AI block, choose a summary in paragraphs, bullet points, or meeting minutes and click Generate summary. The summary comes out in seconds, in the language of the audio, ready to copy.

    What it's for

    WhatsApp audio

    Got an 8-minute voice note? Read the summary instead of listening to it all: what the person asked, what was agreed, and what is still pending.

    Podcasts and interviews

    Summarize the episode or recorded interview as bullet points for show notes, an outline, quotes, or a post, with names and figures as they were said.

    Recorded meeting or appointment

    Recorded an in-person meeting, an appointment, or a client conversation on your phone? Choose the minutes format and get decisions, action items, and next steps.

    Dictated ideas

    Recorded a train of thought on the go? Transcribe it, summarize it in paragraphs, and use it as a draft for an email, a post, or a document.

    Frequently asked questions

    How do I summarize audio with AI?
    Upload the audio file on this page, enter your email (you get a 6-digit code, no password), and click Transcribe audio. Our engine transcribes the speech and, once the text is ready, the Summarize with AI block appears: choose the format and click Generate summary. You end up with the full transcript and the summary, both ready to copy.
    How do I summarize a WhatsApp audio?
    On your phone, press and hold the audio, choose share or export, and save the file (it comes as .opus or .ogg). On WhatsApp Web, hover over the message and download it. Then upload the file here and, once the transcript is ready, click Generate summary. The step-by-step for the transcription alone is on the transcribe WhatsApp audio page.
    What kind of summary does the audio become?
    Three formats, your choice after the transcription. Summary in paragraphs: 2 to 4 paragraphs with the subject, the main points in the order they were made, and how the audio ends. Bullet points: 8 to 16 lines, one point, decision, or fact per line. Meeting minutes: topics discussed, decisions, action items, and next steps. In all of them, names, figures, and dates stay as they were spoken.
    Can I summarize a podcast or a long interview?
    Yes. Upload the episode file (MP3 or M4A) and generate the summary as bullet points or paragraphs. On the free plan, we transcribe and summarize the first 10 minutes; full episodes, up to 2 hours, need Rollin Ferramentas Pro. The transcript does not separate speakers, so the summary does not attribute sentences to the interviewer or the guest.
    What are the limits on duration, size, and summaries?
    Files up to 500 MB. On the free plan, 2 transcriptions per account, up to 10 minutes each, and 3 summaries per day, counted together with the other AI writing tools; if the audio is longer than 10 minutes, we transcribe the first 10 and you decide whether you want the rest. With Rollin Ferramentas Pro, audio up to 2 hours per file, with no limit on quantity or summaries; the price is in the Pro block on this page.
    What language is the summary in? Does it identify speakers?
    The summary comes out in the language spoken in the audio, just like the transcript: English, Portuguese, Spanish, and others, detected automatically. The tool does not translate and does not separate voices: the transcript carries the speech in the order it happened, and the summary does not attribute sentences to people. Before clicking Generate summary, you can fix names and terms right in the transcript; the summary uses the edited text.
    Are the audio and the summary stored?
    No. The audio is sent encrypted and transcribed by an infrastructure provider contracted by Rollin Host only to produce the text. The file is deleted right after processing and the summary is not stored: copy it before leaving the page. We never sell or share the content with anyone.
    I have a video, a text, or a PDF. What now?
    Video (MP4, MOV, MKV): use the summarize video page, which extracts the audio on its own. Recorded meeting: generate meeting minutes. Typed text or a document: summarize text and summarize PDF. If you only want the transcript, without a summary, go to transcribe audio. The other free tools are in the tools hub.

    Need volume or a private API?

    This tool is free for occasional use. To transcribe at scale, with your own API and no duration limit, we offer a dedicated Whisper Server — audio processed on your infrastructure, nothing sent outside.
