Most recordings only become useful after they turn into text. A podcast needs show notes. A client call needs a recap. An interview needs quotes you can search and reuse.

Chat Octopus transcribes audio quickly and accurately. Upload an MP3, WAV, M4A, or any common audio format. You get a timestamped transcript with speaker detection, so you know who said what and when.

Speaker labels put a name on every line. Instead of scrubbing back through a long call to check who agreed to the deadline, you search the transcript and read the answer. And when something comes out wrong, say so in plain language: "That name is Priya, not Prya." "Label the second voice as the client." The whole transcript updates right in the conversation, no file editing, no starting over.

When the transcript is ready, send it where the work is going. Need it in a document or a report? Ask for a DOCX. Subtitling a video? Ask for an SRT and every line arrives matched to its timing. Only after one quote? Copy it straight from the chat and skip the file.

But a raw transcript is only the starting point. Ask Chat Octopus to summarize the key points, extract action items, pull out quotes, or reformat the transcript into meeting notes. The transcript is live context for the conversation, so every follow-up question builds on the full recording.

Podcasters use this to generate show notes and episode summaries. Sales teams use it to capture call highlights without manual note-taking. Journalists use it to find exact quotes across long interviews. Researchers use it to code qualitative interviews.

The transcript stays in your conversation thread, so you can come back weeks later and ask new questions about the same recording.
