Kovo vs Slang.ai: Which Fits Your Restaurant?
Slang.ai is reservation-first phone AI at $450–$600 a month. Kovo is a takeout line at $99. Compare where the call ends, what each costs, and who should buy which.
On this page
Two restaurants can sit on the same block, field the same number of calls, and need opposite phones. One is a 60-seat room where every caller wants a table on Saturday or a question about the prix fixe. The other is a takeout counter where the caller wants a large pepperoni and will hang up if the line rings out.
Kovo sells the takeout counter's phone. It builds the order the way the caller says it and reads it back before it is placed. The ticket prints where the kitchen already looks. A caller who has paid before is recognized by number, and the card the shop already holds is charged while the caller is still on the line.
A table request goes into Kovo's own reservation book. The order limit belongs to the shop, and a website chat runs on the same engine. $99 a month for 750 connected minutes, or $299 for 5,000.
Slang.ai sells the first phone. Its Superhost plan is published at $450 to $600 a month per location (checked October 2026), and the product is organized around reservation requests, guest questions, and pointing order-intent callers at online ordering. Same category on a vendor comparison sheet, different job in the building.
TL;DR
- Kovo is an order line: $99 for 750 connected minutes or $299 for 5,000, with the order read back and the ticket written to Toast, Square, Clover, Olo, or a receipt printer.
- The card closes on the call: a card the shop already holds is charged while the caller is still talking. A first-time caller gets a Stripe link with the line held open. Slang.ai publishes no payment path we could find.
- A table request goes into Kovo's own reservation book, the order limit is the shop's own, and a website chat runs on the same engine.
- Slang.ai is reservation-first: $450 to $600 a month per location for Superhost, published October 2026 per the vendor, with order-intent callers sent to online ordering.
- The entry-tier gap is roughly 4x to 6x, and it buys different work. If your calls are mostly a host stand, that is the product. If they are orders, take one test call on Kovo: 14 days free, no card at signup.
What Kovo is
Kovo answers the phone, takes the order the way the caller says it, reads the order back before it is placed, and sends the finished ticket to Toast, Square, Clover, Olo, or an Epson or Star receipt printer. The menu comes from the shop's own POS catalog or from a menu page, refreshed once a day in the background so an answered call never waits on a vendor. The Toast path is the one most shops test first.
Payment closes on the call. A caller who has paid before is recognized by number, and the card the shop already holds is charged off-session while the caller is still talking. The ticket reaches the kitchen during the call. A first-time caller gets a Stripe link by text with the line held open, and paying it vaults the card for the next call. No card number is spoken to the agent, recorded, or transcribed.
A table request goes into Kovo's own reservation book. Availability comes from the shop's hours and holiday exceptions, one seat is written per slot, and the caller gets a confirmation text. The order limit belongs to the shop: defaults of 10 items in total and 8 of one item. An owner can add a value limit, and a zero turns any of them off. Above a limit, the call rings the handset if the owner routed large parties there, and otherwise the agent says the order is too large to send through and keeps taking what fits. A website chat runs on the same engine, so both channels read one menu.
Pricing is Starter at $99 for 750 connected minutes and Unlimited at $299 for 5,000. Minutes are connected call time: a call under 10 seconds is never billed, no single call bills past 12 minutes, and there is no overage. When the month runs out, calls forward to the shop's own phone instead of being answered, so the invoice cannot run away.
What Slang.ai is
Slang.ai is restaurant phone AI built around the reservation. It answers in a polished voice, handles reservation requests and guest questions, and directs callers who want to order to the online ordering page. Pricing for the Superhost plan reads $450 to $600 a month per location in the October 2026 material we could see, and that figure came through Loman's public review of Slang, which cites Slang's own page. Confirm it on Slang's pricing page before signing anything.
The strength is the conversation and the workflow behind it. A caller asking whether the patio is heated or whether there is a table at 8:30 is the caller this product was designed for. That is a full-service problem, not an order problem.
The 30-second comparison
Every cell below is published by the vendor or observable on a live call. A blank is a fact worth noticing, and any price should be re-checked on the vendor's page before you sign.
| Kovo | Slang.ai | |
|---|---|---|
| Starting price | $99/mo, 750 connected minutes; $299 for 5,000 | $450–$600/mo per location for Superhost, published October 2026 |
| What the call ends with | Order read back, ticket written to the POS | Reservation request or inquiry; order-intent callers directed to online ordering, per the vendor's positioning |
| Where the ticket lands | Toast, Square, Clover, Olo, Epson Server Direct Print, Star CloudPRNT | Not publicly listed — confirm whether an order reaches a POS at all |
| Card handling | A card the shop already holds, charged on the line; a Stripe link for a first-time caller | Not publicly listed — confirm whether a payment path exists |
| Reservations | Its own book, one seat per slot; does not write into OpenTable or Resy | Reservation requests and guest questions are the core of the product |
| Setup | Self-serve: connect ordering, import menu, take a test call | Not publicly listed — confirm the timeline and who imports the menu |
| Website chat | Yes, same engine, embeddable | Not publicly listed — confirm |
| Orders above the limit | The shop's own; defaults 10 items and 8 of one item, optional value limit | Not publicly listed — confirm |
Two rows decide most of these deals, and neither is the price row: where the reservation lands and where the ticket lands.
The price arithmetic at your volume
Start with the plan you would buy. Take a shop answering 900 calls a month at a four-minute average: a four-item pizza order, a read-back, one correction, a question about the wait.
- 900 calls × 4 minutes = 3,600 connected minutes.
- 3,600 minutes fits Kovo Unlimited at $299, with 1,400 minutes to spare.
- Slang.ai Superhost at $450 to $600 leaves $151 to $301 a month on the table, or $1,812 to $3,612 a year.
That gap is the price of the reservation workflow, not a markup on the same service. A restaurant where half the calls want a table is buying a host; a restaurant where nine in ten calls are orders is paying for a feature it will never switch on. The pricing page shows the same minute arithmetic from Kovo's side.
The other half of the case is the call that never gets answered. A QSR Magazine analysis estimates the average restaurant misses about 150 calls a month, and roughly 85% of callers do not try again, a figure usually attributed to BIA/Kelsey. At $35 to $85 a ticket, that is $5,250 to $12,750 a month, and the missed-call math walks through the multiplication.
Two questions to ask on either demo
"A caller wants two pizzas for pickup in twenty minutes. What does the kitchen see, and when?" Do not accept a transcript. Ask for the kitchen ticket, with modifiers, on the POS you actually run. An agent that reads the order back is building it; one that never reads back is narrating, and you find out which you bought on your busiest night.
"Who takes the money, and at what moment?" For Slang.ai the answer begins with whether a payment path exists, because the vendor does not publish one. For Kovo, a card the shop already holds is charged while the call is still running, and a first-time caller gets a link with the line held open.
The decision, by situation
No scorecard, no weighted rubric. Three shops, three answers.
| Your phone, honestly | Pick | Why |
|---|---|---|
| A full-service room where reservations and guest questions are most of the calls | Slang.ai | The host-stand workflow is the product, and Kovo's own book will not put a booking inside OpenTable |
| A takeout line of 400 to 900 calls a month, two to four minutes each, ending in an order | Kovo | Unlimited is $299 for 5,000 minutes, the ticket lands in Toast, Square, Clover, Olo, or a printer, and Kovo's own book takes the table request |
| One line with mixed calls and a hard budget under $150 a month | Kovo | Starter is $99 for 750 connected minutes, and calls forward to your own phone at the cap instead of billing an overage |
Who should pick Slang.ai
Pick Slang.ai if the phone rings for a host stand — tables, pacing, party size, patio questions — and the booking has to land in the platform your room already runs; OpenTable publishes the voice AI partners for its Core and Pro products, which is the cheapest due diligence available.
Who should pick Kovo
Pick Kovo if the phone is a takeout line: pizza, deli, QSR, a counter spot with a queue at noon. Pick it if the calls are "large pepperoni, half mushroom" and "how late are you open". Pick it if you want to be live without a scheduled onboarding and if 750 connected minutes is a realistic month at your call length.

FAQ
Is Slang.ai or Kovo cheaper for a full-service restaurant?
Slang.ai is published at $450 to $600 a month per location for Superhost (October 2026), which is $5,400 to $7,200 a year. Kovo is $99 for 750 connected minutes or $299 for 5,000. The gap is real, but the two bills buy different work: Slang is priced around reservation handling, Kovo around an order read back and printed. Compare the yearly numbers only after you know which calls you get.
Can Kovo handle reservations the way Slang.ai does?
Partly, and the gap is the book rather than the booking. Kovo takes a table in its own reservation book: availability comes from your hours and holiday exceptions, one seat is written per slot, and the caller gets a confirmation text. It does not write into OpenTable or Resy, so a shop whose book is OpenTable has that page read out and texted instead. Slang.ai is organized around reservation requests and guest questions, which is why its price is four to six times Kovo's at the entry tier.
What happens to a caller who wants to place an order?
Slang.ai's public positioning, as Loman's public review of the product summarizes it, sends order-intent callers to your online ordering page. Kovo takes the order on the call, reads it back, and writes the ticket to Toast, Square, Clover, Olo, or a receipt printer. With cards on, a caller the shop already holds a card for is charged on the line; a first-time caller gets a Stripe link, the line stays open, and the ticket prints when payment lands.
Does either product take a card during the phone call?
Slang.ai does not publish a payment path we could find, so ask for it on a live demo rather than a slide. Kovo does. If the shop already holds a card for that number, it is charged off-session while the caller is still on the line, and the ticket reaches the kitchen during the call. A first-time caller gets a Stripe link by text with the line held open, and no card number is spoken to the agent. One call under 10 seconds is never billed.
How long does setup take on each, and how do I test the order path?
Kovo is self-serve: sign up, connect ordering, import the menu, take a test call, and the test prints a $0.00 ticket that never marks an order paid. Most shops get there in a day, and the 14-day trial needs no card. Slang.ai does not publish a setup timeline, so ask who imports the menu, how long it takes, and what a failed import costs you in reservations.
Final Thoughts
The decision is not Slang.ai against Kovo. It is a host stand against a takeout counter, and most operators already know which one their phone is. Slang.ai charges $450 to $600 a month for the reservation workflow and earns it in a room where tables pay the rent. Kovo charges $99 for the order, the read-back, the in-call charge on a card the shop already holds, and a table in its own book.
Take one call with your own menu: a pizza with a half-and-half, one correction after the read-back, then look at what printed. That ticket is the whole argument. Starter is $99, the first 14 days need no card, and you can take a test call with your own menu.
