● B2B offer — Marketing & content

Copywriting assistant: your content, your brand tone

Writing an article, a product page or a newsletter takes less inspiration than method: going back to the documentation, respecting the template, holding the editorial line. Your agent produces a first version from your own documents and your brand tone, ready to work on. Hosted in France — local inference or an isolated resource — your documentation feeds no third-party model. The marketing manager keeps the final word.

✦ In brief

A Blue Lemon Agent marketing copywriting agent produces first versions — articles, product pages, newsletters, sales arguments — from your templates, your brand tone and your internal documentation. It looks nowhere other than in what you give it. It runs on local inference or is hosted in France: your unpublished content and your reference documents stay with you, architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity. Live within a few weeks,.

These figures describe our offer, not results measured at a client: how large the gain is on your volume of editorial production is confirmed by a pilot.

The context

What does an AI agent bring to your editorial production?

The first draft is the longest and least rewarding part of writing. But a consumer tool writes outside your editorial line, and learns from what you give it.

! The issue

Every format means going back to the documentation, finding the right template and holding a consistent editorial line — work of retrieval more than of writing. Yet a consumer assistant produces text outside your tone, often inaccurate, and above all absorbs your unpublished content, your forthcoming launches and your internal documentation into a third party subject to the Cloud Act.

Our answer

A writing AI is only of interest if it is sovereign and bounded by your sources. Local inference or an isolated resource hosted in France, writing from your documents alone, nothing published automatically: the first draft is supplied, the editorial line stays yours. The agent invents no argument you have not written.

The decisive point

Your editorial line and your reference documents: sovereignty & compliance

Your unpublished content reveals your commercial roadmap. Here is how the architecture of our agents protects it, document by document.

Local inference

The agent can run on a machine belonging to your organisation: no unpublished content leaves the network, no documentation passes through a public cloud.

Hosting in France

Otherwise, a dedicated and isolated resource hosted in France, under French law — your content and your internal documentation: processing and access within the European Union targeted by the architecture.

Reduced extraterritorial exposure

For your editorial line and your reference documents, the architecture aims to reduce exposure to the Cloud Act and FISA 702; being located in France or in the European Union does not, on its own, guarantee immunity.

Isolated resource

No pooling: an environment strictly dedicated to your brand and its documentation.

Templates and brand tone respected

Your templates and your editorial guidelines are applied as they stand; encryption, role-based access and logging of everything produced.

AI Act: governed deployment

An agent strictly in support; no content published automatically; traceability and human oversight from end to end.

What depends on the architecture chosen These points are not general guarantees: they are settled deployment by deployment, in the quotation.

  • The applicable location is that of the architecture set out in the quotation and verified before commissioning.
  • Local execution is announced only for the configuration explicitly described and accepted in the quotation.
  • The applicable isolation depends on the deployment mode set out in the quotation; no dedicated isolation is presumed.
  • Roles and permissions are configured and accepted for the identities and systems actually connected.
  • The events logged, their content, their retention period and who may access them are defined for the deployment chosen.
For launches under embargo or content tied to a financial transaction, SecNumCloud and reinforced hosting are options depending on your requirements. A single architecture is designed to answer both the GDPR and extraterritorial exposure. Designed for deployment in line with the GDPR and the AI Act, after the processing, roles and context-specific risks have been assessed.
Demonstration

See the agent at work

5 real situations, taken from those that come up most often. Pick one: the exchange unfolds as it would in your organisation.

A scripted demonstration. These exchanges show how the agent behaves — its sources, its refusals, what it leaves to your teams. Nothing is sent from this page, no model is queried here, and the matters named are fictional. That is precisely what we promise your data.
The behaviours shown here — monitoring, automation rules, routing and reminders — are configured with you during deployment, from your tools, your rules and your thresholds.
The architecture points named in these exchanges — location, local execution, isolation, encryption, role-based access, logging — are not a guarantee attached to the demonstration: they are those of the architecture set out in your quotation, and verified before commissioning.

The company in this demonstration

Fictional company

Hydralis — French manufacturer of pumps and water treatment systems for industry

Sector
Industry — dosing pumps and water treatment systems for food processing and local authorities
Headcount
140 staff, including 3 in marketing (1 marketing manager, 1 content writer, 1 apprentice), 11 in the engineering office and 9 field sales staff
Market
600 industrial customers in France and Europe — sales cycle of 4 to 9 months, technical decision before purchasing decision
Volume
340 catalogue references, 4 articles and 2 newsletters a month, 1 range launch a quarter
Tools in place
The site's content manager, the emailing tool, the catalogue PIM and a 9-year file server — manuals, test reports, press kits, visit reports; the agent plugs into them, nothing is replaced
Who decides
The marketing manager approves and publishes every piece of content; the engineering office signs off every technical claim; the sales director settles the sales scripts
Room for improvement
An article takes 11 days from brief to publication; 214 of the 340 product pages carry only 40 words lifted from the 2019 catalogue; the newsletter goes out late every other month

Hydralis lacks neither material nor rigour: it has nine years of manuals, test reports and visit reports, and an engineering office that reviews everything. What it lacks is the time to go back to that material, find the right template and hold a consistent editorial line across six formats. The agent runs with local inference on a machine at the plant and reads the file server, the PIM and the site: it produces sourced first drafts, marketing keeps the pen and publishes. The exchanges below span a quarter, from writing down the brand tone to the closing review.

This company, its figures and the exchanges that follow were invented for the demonstration. They illustrate a common situation; they describe no real client.

Copywriting assistant · hosted in France
I read nine years of your file server last night — 6,400 files — and wrote down what nobody here had written: your editorial line, as six templates and a tone guide.
Brand tone is the way of writing that belongs to a house: its sentence length, its register, its units, what it allows itself and what it rules out. Your two writers carry it in their heads. It was written down nowhere, so it could not be passed on.
The gap I measured, and it is the gap that decides the gain: I compared the successive versions of your last 22 published pieces. 7 corrections out of 10 were about form — the tone, the template, going back to the documentation. Only 3 out of 10 were about substance. Your content writer is not reviewing ideas, she is re-tuning a voice — the one job that can be written down once and for all.
What the guide contains, and all of it can be checked against your own texts:
· 18-word sentences on average, 81 % active voice, formal address throughout.
· Units always in SI, with the common equivalent in brackets — you have done it since 2019 without ever writing it down.
· No superlatives. Across your 180 approved pieces, « the best » does not appear once.
· The word « solution » is absent from your last 40 pieces — you say « pump », « system », « line ». It is the most discriminating trait of all, and no brand guide ever thinks to write it down.
· No promise of results without test conditions cited: a constraint of your trade, held by your writers without anyone reminding them.
The six templates I reconstructeda template is the imposed skeleton of a format: the order of the parts, what each contains, its length: technical article, product page, newsletter, sales script, application note, launch release. These are the six you already use; I have simply written them down.
What that gives you on the next request: a first draft arrives already in the right tone and already in the right template. Your content writer stops rewriting and starts arbitrating.
What I propose: that the marketing manager read back the guide and the six templates. Every trait can be corrected with a word: it is your own material, I have only made it explicit — and there is nothing to take on trust, everything checks against a text you have published. editorial-guide_tone-and-6-templates.pdf18 words a sentence, 81 % active voice, 25 banned words
⛓ Sourced · file server, 6,400 documents over 9 years, 180 published pieces, successive versions of the last 22
Our manuals, test reports and press kits — nobody can find anything. What do you do with that server?
I index it on the content of the files, not on their names — and every time I tell you which version prevails.
The case that sums it up: you asked me for the DP-40 pump manual last week. Eleven files for it exist on the server. The one that prevails is called DP40_manual_VF_v3_OK_final.pdf, it is dated 18/02/2026 and carries revision index D. The other ten are earlier indexes. I do not read the file name: I read the revision index, the signature date and the product reference inside the document.
What the index found, and what needs a decision:
· 1,940 files out of 6,400 have no usable name — exactly the ones you hunt for on a Friday evening.
· 240 version duplicates, with the risk of starting from an obsolete index.
· 3 obsolete manuals are still linked from your product pages. A customer downloading today receives a document whose index is no longer current. Those need handling this week: your customers read them, not your teams.
· 41 test reports later than 2024 that have never been used in any marketing content. That is your seam of fresh, verifiable arguments, and it is asleep.
The time this moves: finding the source documentation for a piece took 28 % of production time. It now takes 8 %. Your quarterly reports put document hunting at 62 hours — more than a week and a half of work for a team of three.
What indexing does not do, and it matters: it renames nothing, moves nothing, deletes nothing. Your existing paths keep working, and if you stop the monthly pass, the index already built stays.
What I propose: that I run once a month over recent deposits to record the product reference, the index and the signature date. And that the 3 obsolete manuals be replaced first — I have prepared the list of pages concerned and the current file for each. indexed-documentation_6400-files.pdf1,940 with no usable name · 3 obsolete manuals live
⛓ Sourced · file server, content of documents rather than their names, product page links, quarterly reports
Our launches aren't public before the announcement, and our test reports even less so. Where exactly does all this go?
It does not go anywhere. I run with local inference on a machine at the plant, and your file server is copied nowhere.
Local inference means the model computes on your machine: the text of a test report or of an embargoed release never crosses an outside network to be processed. If you would rather not host a machine, the other route is an isolated resource hosted in France, under French law, dedicated to Hydralis — no pooling with another manufacturer.
What that protects, document by document:
· Your unpublished content. The Neris range release has existed for six weeks and the announcement is on 14 October. It tells your commercial roadmap to whoever reads it.
· Your 41 recent test reports. Those are measurements your competitors do not have and would pay for.
· Your 340 visit reports for the year, naming your customers, their installations and their objections.
· And the very fact that you are preparing a launch, which can be inferred from a simple usage log.
How it is held: encryption in transit and at rest; role-based accessrights follow the job: the apprentice opens the templates and published content, not the test reports nor the embargoed documents; logging of every production — which template, which sources, who asked, who approved; hosting in France, architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity.
And none of your data trains a model: what I learn from Hydralis serves Hydralis. Nothing you entrust to me can surface elsewhere, because nothing goes there.
The figure that makes this commercial rather than technical: two of your 2026 public tenders scored data hosting out of 5 points, and your food-processing customer in Nantes prohibits, in its framework contract, any transfer outside the European Union, including for a writing tool. You were able to tick the box with no reservation and no clause to negotiate.
What I propose: that I keep up to date the technical sheet your customers ask for at renewal — hosting, sub-processors, retention periods, who accesses what. It is asked for once a year and hunted for over three days. technical-framework_where-your-content-lives.pdfLocal inference, role-based access, processing in the EU targeted

If adapting the AI agent to your constraints, your needs or your requests requires other paid components — a third-party publisher's software licence, paid API access to one of your applications, hosting of health data, for which French law requires an HDS-certified host (art. L. 1111-8 of the French Public Health Code), SecNumCloud-qualified hosting, a speech synthesis service, particular hardware —, they are offered to you as an option or on quotation and re-invoiced at the cost incurred; nothing is committed without your written agreement. Where the artificial intelligence model you choose entails an additional cost, that cost is shown to you before you order and re-invoiced to you at the cost incurred, with no margin.

Frequently asked questions

Your questions, our answers

Does the agent publish the content itself?
No. It produces a first version, which you work on and publish yourself. Nothing is published automatically: editorial responsibility remains entirely yours.
Can the agent invent arguments or figures?
It writes from the documents you supply alone and is not there to produce new statements. Reading over before publication remains essential nonetheless, as it does for any text prepared by a third party.
How does the agent learn our brand tone?
At the design stage, from your existing content and your editorial guidelines. The tone is configured, not guessed, and you can change it.
Is our unpublished content protected?
Yes. The agent is hosted in France, on local inference or an isolated resource, with the deployment objective of processing and access operated within the European Union and an architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity. Your documents are not used to train a third-party model.
How long does it take to deploy this assistant?
A few weeks as a rule, depending on the number of formats to cover and the volume of documentation to index, after a free audit then a phase of design, integration and testing.
Can it be used for highly technical content?
Yes, provided you give it the corresponding technical documentation. The more precise your sources, the more usable the first version — and a specialist reading it over remains the rule.
