Push-to-talk for fleets

Hold to talk.

Drivers send a voice note. Dispatch hears it at once. AI transcribes, translates and colour-codes every message, so emergencies surface in seconds.

How it works

Voice first. Sorting follows.

A voice note never waits for AI. Dispatch hears the driver within a second, then the transcript, translation and colour arrive a few seconds later.

1

Driver holds to talk

One big button. No typing, no menus. With no signal, notes queue on the phone and send in order when the connection returns.

2

Dispatch hears it at once

The voice note plays in Lighthouse straight away, with the driver's truck, tanker and position attached.

3

AI sorts, people decide

Each message gets a colour and a tag. A rules engine checks the call. A dispatcher confirms, corrects or closes it.

The product

Built for the control room and the cab.

Use cases

For crews that cannot stop to type.

Hailer fits any operation where people drive or work away from a desk, speak different languages, and need dispatch to hear problems fast.

See use cases by sector
Industrial gas and bulk liquids

Hazardous loads on the road

A gas leak or spill on a truck carrying hazardous product is always critical, whatever the AI first thought.

  • Rules override the AI for hazardous cargo
  • Safety words in five languages raise a flag
  • HSE sees every critical item
Fuel and water tankers

Long routes, many drops

Drivers report arrivals, loading and delivery by voice. Dispatch sees them as status updates without a single tap.

  • Status updates tagged automatically
  • Idle and at-site counts on the dashboard
  • Fuel low and breakdown surface as urgent
Construction materials

Time-critical deliveries

When a site is closed or a pour is delayed, dispatch hears it straight away and can re-plan before the next truck leaves.

  • Site closed and waiting at site tagged as notices
  • Geofences show who is at which site
  • Reports list the slowest responses
Distribution and last mile

Customer not available

Every failed delivery is counted and tied to a place, so repeat problem sites show up in the weekly report.

  • Top customers not available, per period
  • Wrong address and refused delivery tags
  • Typed replies are read aloud in the driver's language
Plants, depots and ports

Operators on foot

Facility operators use the same app, located by site. A fall followed by no movement sends an automatic SOS.

  • Fall and no-movement detection
  • Location shown as the site zone on weak GPS
  • Sign-in by QR code, approved by an admin
Mixed-language workforces

Everyone speaks their own language

Drivers speak English, Arabic, Hindi, Urdu or Tagalog. Dispatch reads the original script with a translation beneath it.

  • Mixed-language speech handled
  • Interface mirrors for Arabic and Urdu
  • Safety phrases translated by native speakers

Languages

Say it your way.

Drivers talk in the language they think in. Transcripts keep their own script, with the English translation on the next line. Dispatch works in English or Arabic.

Sample phrases. Safety phrases in the product are translated by native speakers.

Safety and privacy

Safety over silence. Privacy by design.

When the system is unsure, it flags. A false alarm costs a minute. A missed emergency can cost a life. Every company's data stays separate and stays in region.

Each company is private

Every organisation has its own space, users and data. Separation is enforced in the database on every table, and tested.

Data stays in a Gulf region

Storage and processing run in one Gulf cloud region. Only alerts, never audio, leave it, as push, SMS and email.

Audio is encrypted and short-lived

Encrypted in transit and at rest. Audio opens only through links that expire in 15 minutes.

Location only on shift

Drivers always see when location is shared. It stops the moment the shift ends.

No training on your data

Customer audio and text are never used to train AI provider models.

Everything is logged

Sign-ins, approvals, tag changes, exports and access to another person's audio are written to an audit log.

Questions

Plain answers.

Does a voice note wait for the AI?

No. The voice plays in Lighthouse as soon as it arrives. The transcript, translation and colour follow within a few seconds.

Does the AI decide what is an emergency?

The AI suggests a tag. A rules engine in our own code makes the final call, and a dispatcher confirms, corrects or closes it. SOS never depends on AI.

What happens with no signal?

The phone keeps the note and shows how many are queued. When the connection returns, notes send automatically, oldest first.

Which languages are supported?

Drivers can use English, Arabic, Hindi, Urdu and Tagalog. Lighthouse runs in English and Arabic, with Arabic mirrored right to left.

How do drivers join?

An admin creates a QR code. The driver scans it, enters their details, confirms their mobile number by SMS, and waits for approval.

Can drivers chat with each other?

No. Drivers talk only to dispatch. This keeps the channel clear and the driver's attention on the road.
