## Pricing Comparison
### SmartAlex Pricing
| Plan | Monthly Price | Key Inclusions |
| ---------------- | ------------- | -------------------------------------------------------------------------------------- |
| **Professional** | \$99 | 250 included minutes, 1 phone number, 5 concurrent slots, knowledge base, integrations |
| **Dental** | \$349 | Pre-tuned for dental practices |
| **Real Estate** | \$3,000 | 10 phone numbers, lead tracking and CRM, showing bookings, dedicated account manager |
| **Enterprise** | Custom | Volume pricing, SSO/SAML, custom integrations, uptime SLA |
Overage minutes run at roughly \$0.05/min; numbers start at \$2/month across 9 countries. SmartAlex serves restaurants through its general platform and hospitality patterns rather than a dedicated restaurant plan.
### Slang.ai Pricing
Slang.ai uses restaurant-focused subscription plans, reported in the range of roughly \$99 to \$599/month depending on features such as VIP call handling, real-time topic alerts, and AI-powered texting, with unlimited call handling on plans. Confirm current tiers on Slang.ai's pricing page.
### Total Cost of Ownership
For a restaurant that only needs reservation-focused call answering with native OpenTable handling, Slang.ai's specialised plans are purpose-built and include restaurant analytics out of the box. SmartAlex's general platform starts lower and adds outbound campaigns, multi-channel messaging, and CRM, which matter if a restaurant group wants marketing outreach and guest follow-up beyond answering, but it reaches reservation systems through Custom HTTP Tools rather than native restaurant integrations. Match the choice to whether you want restaurant-specific depth (Slang.ai) or a broader, multi-use platform (SmartAlex).
***
## Voice Quality & Vertical Fit
Both deliver natural, guest-ready voice. Slang.ai's strength is fit: it is tuned to how restaurants take calls, with reservation flows, OpenTable integration, and metrics like covers and peak-time analysis built in. SmartAlex uses a curated, low-latency voice stack with 50+ voices and can serve a restaurant well, but its depth is breadth across industries rather than restaurant-specific reservation tooling. If reservations and restaurant operations are the entire job, Slang.ai's specialisation shows; if you want one platform that also does outbound, CRM, and other locations or business lines, SmartAlex is broader.
***
## Integrations
### SmartAlex Integration Ecosystem
SmartAlex ships 40+ integrations as part of the platform, so most connections work out of the box:
* **Telephony**: managed carrier infrastructure across 9 countries, numbers from \$2/month, with geographic permissions and fraud prevention
* **Calendar**: Google Calendar, Outlook, Calendly, Nightsbridge, and iCal for real-time booking
* **Email**: Gmail and Outlook for inbound and outbound, plus dedicated outreach campaigns
* **Payments**: Stripe and Yoco, including secure payment links sent mid-call
* **Messaging**: WhatsApp Business, SMS, and Telegram, plus social channels
* **CRM**: a built-in CRM and deals pipeline, plus HubSpot, Intercom, and Notion
* **AI assistants**: a 28-tool MCP server compatible with Claude, ChatGPT, Cursor, Gemini, and VS Code
* **Custom**: Custom HTTP Tools (Power Tools add-on) so an agent can call your own HTTPS endpoint mid-call
### Slang.ai Integration Ecosystem
Slang.ai integrates natively with restaurant systems, most notably reservation platforms like OpenTable, so it can read availability and manage bookings without custom work. Its integrations are focused and deep on the restaurant stack rather than broad across general business tools.
### Integrations Verdict
For restaurant reservation platforms, Slang.ai's native integrations are the cleaner fit. For general business tools, payments, multi-channel messaging, and programmatic control, SmartAlex covers more ground and can reach reservation systems through Custom HTTP Tools. Choose based on whether restaurant-native or broad-platform integration matters more.

### Choose SmartAlex If You:
* Run any business, or multiple business lines or locations
* Want inbound plus outbound campaigns and multi-channel
* Need a built-in CRM, payments, and analytics in one platform
* Want programmatic control via an MCP server and Custom HTTP Tools
* Are a restaurant group that also wants marketing and follow-up

***
## Migration Considerations
A restaurant moving from Slang.ai to SmartAlex would rebuild the agent in Studio, connect its calendar or reservation system (via Custom HTTP Tools for platforms like OpenTable), and gain outbound campaigns, CRM, and multi-channel. This makes sense for groups that want more than reservation answering. A general business on SmartAlex would only consider Slang.ai if it were specifically a restaurant wanting deeper native reservation tooling.

## Frequently Asked Questions
Both work for restaurants. Slang.ai is purpose-built for restaurants with native reservation management and OpenTable integration, so for reservation-first call answering it is a clean fit. SmartAlex is a general platform that serves restaurants through hospitality patterns and reaches reservation systems via Custom HTTP Tools, while adding outbound campaigns, CRM, and multi-channel. If reservations are the whole job, Slang.ai's specialisation shows; if you want a broader platform, SmartAlex.
Slang.ai integrates natively with OpenTable and similar reservation platforms. SmartAlex does not ship a native OpenTable integration; it handles calendar-based booking and can connect to reservation systems through Custom HTTP Tools (Power Tools add-on). For out-of-the-box OpenTable reservation handling, Slang.ai is the more direct route.
It depends on features. SmartAlex starts at \$99/month for a general voice agent. Slang.ai's restaurant plans are reported from around \$99 up to \$599/month depending on capabilities like VIP call handling and AI texting. For basic answering, entry pricing is comparable; Slang.ai's higher tiers reflect restaurant-specific features. Compare the exact features each includes for your needs.
Yes. SmartAlex includes an outbound campaign system for follow-ups, reactivation, and promotions, plus multi-channel messaging (WhatsApp, SMS, email). Slang.ai focuses on inbound guest calls and reservations, so proactive outbound marketing is not its core use case. If you want to reach guests as well as answer them, SmartAlex covers both.
SmartAlex's multi-tenant workspaces let a group manage separate locations from one account, alongside outbound campaigns and a shared CRM. Slang.ai serves multiple restaurants with its restaurant-tuned product and reporting. For groups that want marketing, CRM, and broader operations beyond reservations, SmartAlex offers more; for reservation-focused multi-location answering, Slang.ai is purpose-built.
