Phone Call Transcription — FAQ

Phone Call Transcription is an AI transcription tool that turns speech into accurate, timestamped text using open-source speech models, in over a hundred languages. It runs free on Free.ai with no sign-up required to get started.

Phone Call Transcription is built for podcasters, journalists, and researchers who need a clean transcript without manual typing. It covers transcripts, captions, and other speech-to-text output — pick this tool when that’s what you need.

Give Phone Call Transcription the source (a file, a link, or pasted content) and it pulls out the text or information you need, cleaned up and ready to use.

Yes. You get 2,500 free tokens per day with no account at all, or 30,000 tokens/day with a free account. Phone Call Transcription draws from that daily pool; if you need more, token packs start at $1.

Phone Call Transcription outputs plain, copy-ready text. Copy it straight out, or export it — signed-in users can save and revisit results from their history.

Give Phone Call Transcription context: who it’s for, the tone you want, and roughly how long. The more direction you give, the closer the first draft lands — then regenerate or edit to taste.

Yes. Text you generate with Phone Call Transcription is yours to publish, edit, and use commercially. We claim no rights over your output.

No. Use Phone Call Transcription immediately as a guest. A free account doubles your daily tokens to 30,000, saves your history, and unlocks larger inputs — but it is optional.

What you type into Phone Call Transcription is not stored beyond the share window and is not used to train models. Signed-in users can choose to save results to their history.

Phone Call Transcription runs on best-in-class open-source AI models on our own infrastructure — no third-party API keys, no per-call surcharge. We update the underlying models as better ones are released.

Yes. Phone Call Transcription works in any modern mobile browser — the layout adapts to your screen, so you can use it on a phone or tablet with no app to install.

A lot. Beyond Phone Call Transcription, Free.ai bundles transcripts, captions, and other speech-to-text output alongside hundreds of other free AI tools — chat, images, audio, video, code, and more — all sharing the same daily token pool. Browse the categories to find your next one.
