[Frequently Asked Questions](https://getnatalia.com/en/comparisons/natalia-vs-diago#faq) - ### Outsourced Receptionist Third-party operators answering your dealership phone. They know cars exist, but not your stock, your workshop schedule, or your DMS. Average cost: $2,000-4,500/month. They read from a script and take messages. Most calls require a callback anyway. Suited for dealerships wanting a human voice regardless of efficiency - ### Dealer Phone System Your existing PABX or VoIP system with auto-attendant. Press 1 for sales, press 2 for service. Routes calls but qualifies nothing. After-hours, it goes to voicemail, which 80% of callers do not leave. Cheap to run, expensive in missed opportunities. Suited for basic routing during business hours - ### Diago AI voice agent specialized for car dealerships, founded in 2023 in Paris. Raised €1M in June 2025 from the Peugeot dealers' association (GCAP) — a first for a dealer association (according to Le Journal de l'Automobile). In September 2025 the professional body Mobilians also entered its capital, for an undisclosed amount (according to L'Argus). Deployed in 30+ dealer groups including Mary Automobiles (according to their website). Handles 80,000+ calls per month. Specialized in workshop scheduling, DMS integration, and automotive-specific vocabulary. Suited for dealerships with high workshop call volume ## AI Voice in Automotive: 2026 Landscape The automotive sector was slow to adopt AI voice. By 2026, two dedicated players have emerged in France: Diago (workshop-first, DMS-native) and Natalia (full dealership phone, multichannel). Generic voice AI platforms also serve automotive but lack DMS integration and auto-specific vocabulary. Natalia covers the entire dealership phone: sales inquiries, service scheduling and general customer service, with WhatsApp and SMS built in. ## Detailed Comparison | Criteria | Outsourced Receptionist | Dealer Phone System | Diago | Natalia | | --- | --- | --- | --- | --- | | Workshop scheduling | Manual (callback) | No | Core strength (DMS-native) | Yes (through your tool's API, Web service action) | | DMS integration | No | No | Yes (native, auto-specific) | Through your DMS or CRM API | | Auto vocabulary | Basic (script) | None | Deep (makes, models, services) | Trained on automotive context | | Sales call handling | Script-based | Routes to sales | Secondary focus | Core strength | | WhatsApp/SMS | No | No | Not documented | Yes (texts the caller during or after the call, answers incoming messages) | | After-hours coverage | Limited (shift-based) | Voicemail | 24/7 | 24/7 | | Deployment time | 1-2 weeks | Already installed | Project-dependent | 48 hours (pilot) | | Monthly cost | $2,000-4,500 | Included in telecom | Contact for pricing | From €99 | | Multichannel | Phone only | Phone only | Phone (voice-focused) | Phone + WhatsApp + SMS | | Dealer groups served | N/A | N/A | 30+ (according to their website) | Automotive clients active | ## What makes Natalia different from Diago - ### Full dealership phone, not just workshop Diago excels at workshop scheduling. Natalia handles everything: sales inquiries, service booking and general customer questions. One AI for the whole dealership, not just the service department. - ### WhatsApp and SMS alongside the phone The agent texts the caller during or after the call, and answers customers who write on WhatsApp or by SMS, at any hour, alerting the right team. Diago focuses on voice. - ### 48-hour pilot, transparent pricing Running in 2 days, starting at €99/month. No multi-week integration project. Natalia connects to your existing phone system, and to your CRM through its API (Web service action), without touching your DMS if you prefer. - ### Not locked to automotive Natalia works across sectors. If your group also runs rental, insurance, or other businesses, the same platform covers all of them. Diago is automotive-only, great focus, but limited if you diversify. ## How to Choose Between Natalia and Diago Choose Diago if workshop scheduling is your number-one problem and you need deep DMS integration (native connection to your dealer management system). Choose Natalia if you need full dealership coverage (sales + service + customer questions) with WhatsApp/SMS multichannel. For large dealer groups with a dedicated DMS workflow and high workshop call volume, Diago's specialization delivers real value. For dealerships wanting a single AI that handles every call type and also answers on WhatsApp and SMS, Natalia is the broader solution. ## Hidden Costs in Dealership AI DMS integration projects can take weeks and involve your DMS vendor's professional services team (billable). Factor in: DMS connector fees, staff training on new workflows, and the opportunity cost of calls missed during deployment. Also consider: what happens to calls outside the workshop workflow? If Diago handles workshop but sales calls still go to voicemail after hours, you have solved half the problem. Calculate the revenue impact of every call type, not just service. ## When Diago Is the Better Choice Diago has a clear edge on DMS workshop integration and automotive vocabulary. If 90% of your calls are workshop-related (scheduling, service follow-up, parts ordering) Diago is probably the better pick. Their native DMS connection means workshop appointments land directly in your system without middleware. Natalia brings multichannel (voice + WhatsApp + SMS) and covers other dealership needs (sales, general customer service, web leads). If your calls are diverse, Natalia handles the full spectrum. ## Frequently Asked Questions ### Does Natalia integrate with dealer management systems? Natalia connects to your CRM or DMS through its API (Web service action), provided your DMS exposes one. Diago has native DMS integration built for automotive specifically. ### How many dealerships use Diago? 30+ dealer groups including Mary Automobiles (according to their website), handling 80,000+ calls per month. Diago raised €1M in June 2025 from the Peugeot dealers' association (GCAP), and the professional body Mobilians joined its capital in September 2025 for an undisclosed amount (according to Le Journal de l'Automobile and L'Argus). ### Can Natalia handle workshop-specific vocabulary? Yes. Natalia is trained on automotive context: makes, models, service types, parts terminology. The difference is that Diago's vocabulary is deeper on workshop-specific flows (oil change intervals, brake pad references, service history). ### Which is better for a multi-brand dealership group? Depends on your priority. Diago for uniform workshop scheduling across brands with DMS sync. Natalia for full-phone coverage (sales + service + customer questions) with multichannel across all brands. ### Can I use both? Technically possible: Diago for workshop-specific calls, Natalia for everything else. But running two AI voice systems on the same phone line adds complexity. Most dealerships pick one and optimize it. - ### Missed Call Cost What a missed call really costs your dealership - ### SMS vs WhatsApp Channel comparison for dealerships - ### Locomotive Alternatives Alternatives to Locomotive for dealerships ## AI for your entire dealership phone 30-minute demo.
