⚔️ Abrège vs ChatGPT
ChatGPT answers everything. Abrège summarises your voice notes.
ChatGPT is now reachable on WhatsApp, via a dedicated number: a general-purpose assistant you chat with. Abrège isn't a separate number but a contact you forward a received voice note to, and it replies with a summary, in the same thread.
Where ChatGPT is a good choice
Credit where it's due: ChatGPT is the most powerful model in this comparison. For reasoning, writing, coding, translating or explaining, it has no equal, and reaching it right inside WhatsApp is very handy. If you want an assistant that can do anything, one that can also summarise an audio clip you send it, OpenAI is hard to beat on raw model quality. Abrège is not a foundation model and doesn't try to be.
Where Abrège changes the game
The difference is in the flow, not the power. With ChatGPT on WhatsApp, you chat with a separate number: you open that conversation, send it the audio, phrase your request, read, then go back to the original thread to reply to the person. With Abrège, the voice note you got from a friend, you forward once to the Abrège contact, and the summary comes back without leaving the logic of the conversation. The summary is tuned for spoken language, and the product does only that: it has neither the latency nor the verbosity of a general assistant you have to explain everything to. You're not trying to have a dialogue with an AI, you just want to know what the voice note said.

Choose ChatGPT if...
- → You want an assistant that can do anything, not just voice notes.
- → Raw model quality matters more than the simplicity of the action.
- → Chatting with an AI in a dedicated chat doesn't bother you.
Choose Abrège if...
- You just want to know what a voice note says, without switching conversation.
- The action has to be a simple forward, with nothing to type.
- You want a summary built for the way people actually speak.
Frequently asked questions
- Yes, you can send an audio clip to ChatGPT on WhatsApp and ask for a summary. But it's a separate conversation: you open the ChatGPT number's chat, drop the audio there, phrase your request, then go back to the original thread. Abrège removes that detour: you forward, you get the gist.
- Abrège relies on OpenAI's models (Whisper for transcription, a language model for the summary). Abrège's value isn't the model, it's the product around it: one move inside WhatsApp, a concise summary tuned for spoken language, and nothing to explain.
- For the single case of WhatsApp voice notes, Abrège: the action is a forward, the reply is a summary, you stay in the conversation. ChatGPT is more powerful but routes you through a separate chat every time.
- Access on WhatsApp was first offered with no account and usage limits, and is gradually moving closer to the usual OpenAI plans. Abrège needs no account to start: you forward a voice note and get a summary, up to 5 a month for free.
