“Doxycycline for acne in a patient 8 weeks pregnant?”

Tetracyclines are contraindicated beyond the 1st trimester and discouraged from early pregnancy[1]. For acne in pregnant women, benzoyl peroxide and certain topicals are preferred[2]. A dermatology reassessment is recommended[3].

The right answer exists.
Finding it takes too long.

Between one consultation and the next, you have a few minutes to decide. The answer is somewhere — in a guideline, a recent article, a drug-safety notice, a PDF you filed away last year.

But finding it means juggling ten tabs, cross-checking sources that contradict each other and rephrasing the same query three times. Too often, you decide from memory for lack of time.

01

Sources scattered across official guidelines, literature and your own documents

02

Generic AI answers, with no citation, impossible to verify

03

The nagging doubt: is this information still up to date?

Everything you need for smart consultations

Chat, documents, forum and multi-agent search — built for physicians, hosted in France.

Deep search

Multi-agent coordinator

For complex questions, a coordinator breaks down your query and dispatches agents in parallel across your documents, the forum, official guidelines and articles. One single, sourced, verifiable answer, reasoning streamed in real time.

Guidelines and scientific articles

French guidelines (HAS, ANSM, learned societies) and international articles (PMC, Lancet…) through a dedicated pipeline. Every answer cited.

Your documents, AI-searchable

Upload your PDFs: automatic extraction, hybrid indexing (vector + full-text), per-page citations. Scoped to your account or your team.

Instant context: screenshots & documents

Drop a screenshot or a document into the conversation: automatic OCR, text used as context at once, no storing first. Perfect for a one-off question about a report or a lab result.

Collaborative medical forum

Ask the community, upvote the best answers, let the AI synthesize the threads in your specialty.

Clinical document drafting

Discharge summary, referral letter, prescription or free-form synthesis: the AI drafts a structured document from the conversation, editable in the chat and exportable to .docx. Missing values stay flagged "to complete" — never invented.

Data sovereignty

AI model and data processed and stored in France at OVH, never with a foreign provider. Your interactions stay private: chat history is stored locally on your device. Per-team scoping and access logging.

From question to sourced answer, in three steps

No prompt to fine-tune. Ask the way you'd ask a colleague.

01

Ask your clinical question

In plain language, the way you'd ask a colleague. No identifiable patient data required.

02

The coordinator dispatches its agents

It breaks down your question and queries official guidelines, scientific articles, your documents and the forum in parallel — reasoning streamed in real time.

03

Get a verifiable answer

A single synthesis, every claim linked to its cited source. You always have the final say.

I built Horizon as the tool I wanted between two patients: a reliable, sourced answer without leaving my workflow or exposing any patient data. Not a gadget — an assistant that cites its sources and leaves the decision to you.

Frequently asked questions

What every healthcare professional should know before getting started.

Is my patient data exposed?+

No. Don't include any identifiable patient data in your questions. Horizon is built for general clinical reasoning, not for handling named records. The AI model and data are hosted in France, at OVH, with per-account and per-team scoping.

How do you avoid AI-fabricated answers?+

Every search answer is grounded in real, cited sources: HAS/ANSM guidelines, learned societies, PubMed/PMC articles, or your own documents. You can trace each one back to its source in one click before you decide.

Does this replace my clinical judgment?+

Never. Horizon synthesizes and sources information to save you time. The decision, the interpretation and the responsibility remain entirely yours.

How long does it take to get started?+

A few minutes. Create your account, ask your first question — no installation, no credit card required to start.

Which sources does Horizon query?+

French guidelines (HAS, ANSM, learned societies), international literature (PubMed, PMC, The Lancet…), your uploaded documents and the peer forum — in parallel, then synthesized.

Do my documents stay private?+

Yes. Your uploaded PDFs are scoped to your account or your team, indexed for search and never shared outside your perimeter.
