The customer can’t describe the fault, the advisor can’t see it. So someone is sent out just to look, sometimes with the wrong part.

incl. VAT: the public price of a home service visit at two major French appliance makers.
Your customer installs nothing and creates no account. They tap a link, that’s all.
One click from their screen, during the call. The voice stays on the phone line, nothing drops.
The link opens the rear camera in the browser. Their face never appears. Weak signal? The video adapts.
Photos, serial number, error code, diagnosis: the report fills in during the call and goes to your CRM.

Other tools stop at the video. Letmisi keeps going: the report is already written, photos are filed, the customer record is up to date. The advisor reads, corrects if needed, approves.
Customer reports a red light and error E04. Pressure read: 0.6 bar. Guided refill to 1.5 bar, then reset: the unit restarts.

Fictional example
Your customer talks to your advisor. AI writes, afterwards.
We don’t put a bot on the line. AI works for your team: it reads, summarises and fills in. The advisor keeps the relationship, and the decision.
90% of French consumers would rather wait for a human than talk to a virtual agent.
Four situations your advisors know by heart.
The customer films the display and the pressure gauge. The advisor guides the refill. No visit on Monday.
Heat pumps
You see the panel and find the circuit. If a technician must go, they leave with the right part.
Electrical and alarms
The model is read off the plate, the setting is fixed live. The report logs the steps.
Heating
Code, model, serial number: all captured without spelling it out over the phone.

Indicative estimate. Assumptions: 1.5 h per visit, van at 8 L/100 km, 3.1 kg CO₂e per litre of diesel (ADEME Base Carbone, via Banque de France 2026).
We spell out where your data goes, AI included. Platform commitments, detailed in the data processing agreement (DPA).
The site you are reading uses neither Google Fonts nor ad trackers.
Nothing to install for your advisors either. The report goes out by email or PDF from day one. CRM and telephony connectors come next.
Planned connectors
Letmisi is just starting. Rather than invent numbers, we offer to measure them with you, on your real calls.

Letmisi is a visual call tool for after-sales service. During a phone call, the advisor sends a text message; the customer taps the link and films the device with their phone’s rear camera, with no app. AI then writes the report (photos, serial number, error code, diagnosis), which the advisor reviews before sending it to the CRM. Letmisi is published by Smartekko SAS and hosted in France.
No. The text contains a link that opens in their phone’s browser. No account, no install.
Video adapts to bandwidth. If it drops, the voice carries on over the phone and the advisor can ask for a photo.
Never. The rear camera opens, pointed at the device.
To servers in France, kept 90 days by default. Details in the security section and the DPA.
A thirty-minute scoping call, then your advisors get their access: everything runs in the browser, nothing to install. Reports go out by email or PDF from day one; CRM connectors come next.
One button on their screen, a report they no longer have to write: it gives time back, it is not one more tool.
Pricing depends on your volumes and options (AI report, connectors). We send a proposal after the scoping call.
A few lines are enough: your business, your volumes, what costs you most.
