⚔️ Abrège vs Luzia
Luzia can do everything. Abrège does one thing.
Luzia is a general-purpose AI assistant, used mostly through its app and offered in beta on WhatsApp in select countries: it answers questions, generates images, translates, and lists transcription among its features. Abrège does one thing, summarise the WhatsApp voice notes you forward it, and does it thoroughly.
When is Luzia a good choice?
Let's be fair: Luzia does far more than Abrège. It's a free all-rounder, very popular in Spain, Latin America and Brazil (Luzia says it has more than 85 million users), that holds a real conversation, generates images, explains a topic, translates, and takes both text and voice. If you want a Swiss-army-knife AI for varied daily use, in its app or on WhatsApp where the beta is open, Luzia is an excellent choice, and Abrège competes on none of those fronts. We don't chat, we don't make images, we don't do homework.
What does Abrège do differently from Luzia?
The difference is this: a generalist treats voice notes as one feature among many, whereas we've made it our only job. With Abrège, you forward a voice note to the contact and get the gist back in two or three sentences tuned for spoken language, and the full transcription follows in the same thread. No prompt to write, no conversation to keep going: the action is a forward, the reply is a summary. Where a general assistant returns correct but standard text, a dedicated tool nails exactly what matters for a voice note received ten seconds ago: speed, brevity, and staying inside the WhatsApp thread.

Choose Luzia if...
- → You want a versatile assistant, in an app or on WhatsApp where it is open, not just for voice notes.
- → You ask questions, generate images, translate day to day.
- → A free, all-in-one service is enough for you.
Choose Abrège if...

- You want the gist in three lines, without writing a prompt.
- You want a summary tuned for the way people actually speak.
Frequently asked questions
- Luzia made its name in 2023 by transcribing WhatsApp audio, and transcription is still listed among its features. We could not verify in September 2026 what its WhatsApp contact, now in beta, does with a forwarded voice note. For Abrège it's the only job: you forward, you get the summary, then the full transcription.
- Because the need is narrow: to stop listening to voice notes. A generalist asks you to explain what you want and returns standard text; a dedicated tool turns the forward into a summary, with no prompt, in the brevity and tone suited to a message received a moment ago.
- Yes, Luzia is free, with an optional paid upgrade, Luzia+ (no ads, longer chats). Abrège offers 5 summaries a month for free, then €3 a month. For a versatile free assistant, Luzia; to just fix the voice-note problem, Abrège.
- Of course. Many keep a general assistant for everyday questions and a dedicated tool for voice notes. Abrège lives in WhatsApp; Luzia mostly in its app, and on WhatsApp where its beta is open. They don't get in each other's way.
