The essentials

Anthropic unveiled “Claude Duet” on 21 October, an AI agent that watches your connected apps and alerts you without being asked. For now it is a research preview reserved for Pro and Max subscribers in the United States, on a waiting list.

What it does

Each morning it sends a short summary of the important items in the connected apps, then checks them all every few hours and alerts you if needed. According to the press, it runs in its own virtual machine in the cloud, with a browser, and so keeps working after the computer or phone is closed.

Actions subject to approval

Duet acts on its own but asks the user’s permission before high-stakes actions: sending a message, paying, signing a document, deleting a file. The balance between warning first and not acting alone on what matters is at the heart of the concept.

Availability and price

Reserved for Pro and Max subscribers in the United States, after joining a waiting list; usable on claude.ai and in the apps (iOS in particular). Team and Enterprise plans are not yet included. No separate price: it is included in the subscription.

Competition and limits

Anthropic positions Duet against Muse (Meta) and Dots (OpenAI), agents that act by themselves. The company acknowledges an early research preview that may misjudge what is urgent, and says it will adjust it based on feedback. It is said to be less comfortable with personal tasks such as booking tickets.

To keep in mind

This article is based on Anthropic’s announcement and on MacRumors, 9to5Mac and other media. Details (apps, regions) vary between articles; check Anthropic’s official announcement.

LANGUAGE NOTES

Learn the grammar

Explained in English

French grammar

Learn sentence patterns and usage from the article’s own sentences.

01The present indicative
Structure

est / sont + attribute (noun, adjective, prepositional phrase)

In the article
Annoncé par Anthropic le 21 octobre : ce qu’est cet agent, qui peut l’utiliser et les limites.
Key points

Être in the present is est for a singular subject and sont for a plural one. It describes nature, state or place (“is”, “is located”). If what follows (the attribute) is a noun, adjective or prepositional phrase, it is not a passive. If a past participle follows, it is a passive (est annoncé). Headlines and summaries often use the present to describe the current situation.

02The passé composé
Structure

present of avoir + past participle

In the article
Les chiffres viennent des entreprises ou des organismes cités ; JAPANITIES ne les a pas vérifiés.
Key points

The passé composé is the most common past tense, used for “did” and “has done” — actions completed in the past. It is formed with the auxiliary avoir (a / ont…) in the present + a past participle. Past participles of -er verbs end in -é (annoncer → annoncé); learn the irregular ones (faire → fait, prendre → pris, voir → vu). In the negative, ne … pas wraps the auxiliary (n’a pas annoncé). In the news it reports facts that have already happened, such as “announced” or “voted”.

03The imparfait
Structure

stem (nous form of the present) + -ais / -ait / -ions / -iez / -aient

In the article
Anthropic a dévoilé le 21 octobre « Claude Duet », un agent d’IA qui surveille vos applications connectées et vous prévient sans que vous le demandiez.
Key points

The imparfait describes states, background, habits and actions in progress in the past (il était, elle avait, ils pensaient). Take the nous form of the present, drop -ons, and add -ais / -ais / -ait / -ions / -iez / -aient. If the passé composé gives “the event itself”, the imparfait paints “the situation at the time”.

04The present conditional
Structure

stem (infinitive) + -ais / -ait / -ions / -iez / -aient

In the article
Il serait moins à l’aise pour les tâches personnelles comme réserver des billets.
Key points

The conditional expresses possibility, supposition, unconfirmed information and polite requests (“would”, “might”). It uses the same stem as the future and the same endings as the imparfait (-ais, -ait, -ions, -iez, -aient): pouvoir → il pourrait. In the news it is used to avoid asserting, as in “is reported to…” or “there is a possibility…”.

05The present subjunctive
Structure

il faut que / pour que / bien que + subject + subjunctive

In the article
Anthropic a dévoilé le 21 octobre « Claude Duet », un agent d’IA qui surveille vos applications connectées et vous prévient sans que vous le demandiez.
Key points

The subjunctive expresses wish, need, purpose, doubt and feeling rather than “fact”. It is used inside a clause with que. Triggers: il faut que (must), pour que / afin que (so that), bien que / quoique (although), avant que (before), souhaiter que, vouloir que and others. Formation: stem of the ils present minus -ent + -e, -es, -e, -ions, -iez, -ent. Irregular: être → soit, avoir → ait, aller → aille, faire → fasse, pouvoir → puisse, savoir → sache.

06The passive voice in the present
Structure

être (est / sont) + past participle (+ par / de)

In the article
Pas de prix séparé : il est compris dans l’abonnement.
Key points

The passive means “is done” or “is being done”. It is formed with être + past participle, which agrees with the subject in gender and number (la mesure est adoptée / les mesures sont adoptées). The agent is introduced by par (or de). In the news it is common when the event, rather than the actor, is the focus (est prévu / est annoncé / est connu).

07The imperative
Structure

present vous form (-ez) / nous (-ons) / tu

In the article
Les détails (applications, régions) varient selon les articles ; consultez l’annonce officielle d’Anthropic.
Key points

The imperative expresses commands, requests and advice. It has no subject: the sentence starts with the verb (Consultez les informations.). The vous form ends in -ez, nous in -ons (Restons prudents.), and tu in -e for -er verbs (Consulte). It is very common in notices and warnings (Vérifiez, Consultez, Restez informé).

08Negation and its scope
Structure

ne / n’ … pas · ne … plus

In the article
L’équilibre entre prévenir en premier et ne pas agir seul sur l’important est au cœur du concept.
Key points

Normally ne and pas wrap the verb. Before a vowel, ne becomes n’. Check which part of the sentence the negation covers. Ne … plus means “no longer”.

09Citing a source with selon
Structure

selon + noun / organisation

In the article
Selon la presse, il tourne dans sa propre machine virtuelle dans le cloud, avec un navigateur, et continue donc à travailler une fois l’ordinateur ou le téléphone fermé.
Key points

Selon means “according to”. Put a person or organisation after it as the source. It separates facts the writer checked directly from what another body or report said. Citing a source does not turn a forecast into an accomplished fact.

10Pouvoir: ability and possibility
Structure

peut / peuvent / pourrait + infinitive

In the article
Annoncé par Anthropic le 21 octobre : ce qu’est cet agent, qui peut l’utiliser et les limites.
Key points

Put a base-form verb after pouvoir. Peut means “can” or “may”; the conditional pourrait gives a more reserved possibility, “might”. It does not necessarily mean implementation is settled.

11Purpose with pour
Structure

pour + infinitive

In the article
Un « aperçu de recherche » est une version encore incomplète confiée à quelques utilisateurs pour recueillir des avis.
Key points

This is the purpose, “in order to…”. Put the base form of a verb after pour. The purpose stated here is separate from whether the effect was actually achieved.

12The subject relative pronoun qui
Structure

noun + qui + verb

In the article
Anthropic a dévoilé le 21 octobre « Claude Duet », un agent d’IA qui surveille vos applications connectées et vous prévient sans que vous le demandiez.
Key points

Qui continues a description of the person or thing just mentioned (“the one that does…”). Because qui is itself the subject of the next verb, do not repeat the subject. The verb agrees with the noun qui refers to.

Explained in English

Japanese grammar

Understand the structure and usage from the text.

01Citing a source: によると
Structure

noun + によると

In the article
報道によると、専用のクラウド上の仮想マシンで、ブラウザを使いながら動くため、利用者が、ノートパソコンやスマートフォンを閉じても、作業が続きます。
Key points

As in “LCPによると”, it shows where the information comes from. What that source reported follows. It is used differently from “私にとって”, which gives one’s own opinion.

02Polite negation and plain form
Structure

〜ではありません / 〜ではない

In the article
航空券の予約のような、個人的な用事は、まだ得意ではないとも報じられています。
Key points

They negate a noun and similar content. “ではありません” is the polite form and “ではない” the plain form. “成立ではありません” shows that it cannot be said to have been concluded.

03Cause or purpose with ため
Structure

〜ため / 〜ために

In the article
「試験版(リサーチ・プレビュー)」は、まだ完成していない段階で、一部の人に使ってもらい、意見を集めるためのものです。
Key points

ため is used for both reason and purpose. “成立ではないため” is a reason and “運転手を守るため” a purpose. Decide from the whole sentence whether what precedes is a cause or a goal.

04Giving examples with など
Structure

noun / expression + など

In the article
WebのClaude.aiと、iOSなどのアプリで使えると、報道されています。
Key points

“暴言など” gives “abusive language” as one example. It is not necessarily a closed list of only the things named. It also helps when reading the scope of a news story.

05The polite past ました
Structure

verb stem (連用形) + ました

In the article
Anthropicが21日に発表しました。
Key points

In “発表しました”, ました makes a verb polite past. The negative is “ませんでした”. Read the actual date together with the date and time in the text.

06Quoting with と: content and report
Structure

plain-form sentence + と + verbe de parole (報じる, 説明する…)

In the article
「先に連絡する」ことと、「勝手に重要なことをしない」ことの両立が、設計の中心だと説明されています。
Key points

と takes the content that is reported or explained. In “改定する方針だと報じました”, “改定する方針だ” is what the report said. Separating the content from who said it and how makes long sentences easier to read.
