Tonvo vs ChatGPT Voice Mode

ChatGPT voice mode lets you talk with ChatGPT and hear it answer out loud. Tonvo is for a different moment: you are talking with a person, and Tonvo listens from your side, shows the question you were just asked and up to three replies you can say.

Why choose Tonvo

Made for Talking With People

Tonvo stays quiet. The other person hears only you, and the suggestions appear on your screen while they wait for your answer.

The Question, Pinned

Tonvo shows the question you were just asked, so you can answer the part that matters even if you lost the thread for a second.

Up to Three Replies

Short replies you can say as they are or put in your own words. Tonvo can be wrong, so you decide what to say.

No Audio Stored

Tonvo does not record or store audio, and no bot joins the call. The text of your sessions is kept so you can read it again.

Talking to an AI or Getting Help While You Talk

ChatGPT voice mode suits a conversation with an assistant: you think out loud, practice a language or ask something quick, and it answers. Tonvo is built for the conversation itself, with a client, a landlord, a colleague or someone close to you, when you want the right words while the other person waits. They do different jobs, and you can use both.

Frequently asked questions

What is the main difference between Tonvo and ChatGPT voice mode?
In ChatGPT voice mode, ChatGPT is the one you talk to: you speak and it answers out loud. With Tonvo, the person you talk to is a human, on a call, in a meeting or in the same room. Tonvo listens from your side, shows the question that was just asked and suggests up to three replies on your screen. You say them in your own words, if you want to.
Can ChatGPT voice mode follow a conversation between two people?
OpenAI's help center (checked in October 2026) says its Live voice option is designed primarily for one-on-one conversation with ChatGPT, is not yet optimized for several speakers, and may respond when people are speaking to one another. Tonvo is built to follow a conversation between you and other people, and it never speaks in the conversation.
Can I use both?
Yes. ChatGPT voice mode suits thinking out loud with an assistant, practicing a language or asking a quick question. Tonvo is for the minutes when someone is waiting for your answer. Before a session, Tonvo can also turn a short description of the conversation into a goal, a few opening lines and the questions you may get, then keep that description in mind while it listens. The two do not overlap much.
Does Tonvo keep the audio?
No. Tonvo does not record or store audio. It transcribes live, and the text of your sessions is kept so you can read it again. For comparison, OpenAI's help center says audio clips from its Live and Advanced voice conversations are stored with the chat transcript and kept for 30 days.
Should I tell the other person I am using Tonvo?
Tonvo is meant for honest use. Tell the people you talk to when you use a tool like this, ask for consent where it is required, and do not use it where AI help is not allowed, such as an exam or a test.
