Human and AI
remote simultaneous interpreting
No booth to build the day before, no receivers to count at the door, no deposit to advance. Your interpreters go on air from a browser; your attendees listen on the phone already in their pocket. One more language can be added mid-event, with no hardware and no technician. Bring your usual interpreters — or we book one for the date.
One free 4-hour event · no card required · nothing to install
Your interpreters, or ours
They go on air from a browser, one per language. Don't have one for that date? Book an interpreter from the console.
No hardware
A link to share, a QR code at the door. Everyone listens on their own phone — no attendee app to install.
52 languages and dialects
Including Moroccan Darija, Algerian, Tunisian, Egyptian and Levantine Arabic — as they are actually spoken, not Modern Standard Arabic.
Options, if you need them
Live captions, AI interpretation, hybrid mode: switched on when you ask, never by default.
You have seen what SIWEL does. Here is what its name means.
SIWEL, letter by letter
Five letters, five promises. The logo stands up and reads top to bottom: follow it from the S down to the L.
Solution
A complete solution, not a component to integrate. You create the session, you share a link — that is all. No equipment to rent, no app to install, no IT project.
Intelligent
AI when you ask for it, never by default. Machine interpretation for an internal stand-up, human interpreters for a board meeting, and both in the same session if that is what you need.
Worldwide
Your audiences are not in the same place and do not speak the same language. SIWEL streams as many languages as you need, to listeners in the room and across three continents.
E-remote
Everything runs in a browser. Interpreters work from home or from their booth, attendees listen on their phones. No headsets to hand out, no console to install on site.
Liability
Who interpreted what, in which language, at what time: every session is traceable. Human or AI, the origin of each voice stays identifiable — which is what sensitive files require.
52 languages, live voice and text
When no interpreter covers a language on the day, the automatic mode takes over: it listens to the speaker, translates, and speaks into the attendee's ear — who can read the text at the same time.
languages understood. The speaker talks, the system transcribes, the attendee hears their own language — with nothing added to the room.

GDPR compliant,
and processed in France.
Your event audio does not leave France. The service is hosted in France, transcription runs on our own machines in Paris, and so do the synthetic voices. That is every account's default setting, not an option you have to ask for — and we publish, on a separate page, exactly what is processed where.
for hosting and listening. Server in France, compute card in Paris, synthetic voices on our machines. The GDPR frames every step, and we name who does what.
and the text is erased. An automatic purge takes care of it: not a commercial promise, a server task that runs on its own.
recordings, unless you ask. And then it requires a declared purpose and legal basis before the first byte, then erases itself after 7 days.
Human interpretation produces no text at all: nothing to transcribe, nothing to keep, nothing to transfer. We name our sub-processors, we state what each one receives and when, and an account can be locked to "nothing leaves the server" — which is what sensitive files require, and we document it rather than simply asserting it.
Three minutes of setup, no logistics
Same day, from a browser. Nothing to rent, nothing to hand out.
You create the session
You set the floor language and the languages to interpret into. The listening link and its QR code are ready straight away.
Your audience scans
The QR code on a sign at the door, or the link sent the day before. Each person picks their language as they arrive.
Your interpreters go on air
One per language, several taking turns if the session is long. The console shows who is interpreting and how many people are listening.
What you stop renting
A quote for interpretation equipment hire means a booth, headsets, receivers, a technician on site and a deposit. SIWEL removes the whole line: your audience listens on the phone already in their pocket.
No equipment to rent, hand out or collect
No booth to build, no headsets to give out at the door, no rental receivers to count back at the end, no deposit. A QR code on a sign, or a link sent the day before.
Make an existing event multilingual
A room, a webinar, or a hybrid event running both at once. You change nothing about your venue or your video platform: SIWEL sits on top, the same day if you need it to.
Dialects, not just official languages
Someone from Morocco does not speak the Modern Standard Arabic of the evening news. Your interpreters hold Darija, Algerian, Tunisian and Levantine the way your audience actually speaks them.
Nothing is kept after the session
Neither the audio nor the captions. What remains is the usage line that justifies your invoice — and you can read it back whenever you want.
What you can add, if you need it
Human interpretation is enough for most sessions. Everything else is switched on account by account, at your request.
Live captions and transcription
What is said appears as text alongside the voice. Useful in a noisy room, and for anyone who reads better than they hear. The text stays readable during the session and goes away with it.
Book an interpreter
A form in the console: date, duration, floor language, target languages, location. The request reaches us and we call you back to confirm it.
AI interpretation
The machine transcribes, translates and speaks. For a language no interpreter covers that day, or for an always-on helpdesk. In hybrid mode the interpreter holds the sensitive language and AI takes the rest.
A quote, not a grid
Your audience size, your languages, your duration: no two events are alike, and a price grid always ends up charging one client for what another one needs. Describe your programme and we price it on the real configuration — answer within one working day.
Public tender, purchase order or framework agreement: tell us the format your finance team needs. Write to us.
Try it on a real meeting
One free four-hour event, no card, with your own interpreters. Enough to run a full morning and judge it on the evidence rather than on a sales demo.
