8 Best Ada Alternatives for AI Customer Service (2026)
Ada, the Toronto AI customer service company formerly known as Ada Support, has been building AI agents since 2016, and more than 350 enterprises run on it. People start looking for an Ada alternative at two moments: when the quote arrives (there’s no price list, and the contract is annual and paid upfront), and at renewal, when Ada’s standard terms add 10%.
The other reason is the phone. Ada’s voice agent is built to plug into an enterprise contact center, and Ada’s own docs say it may not be in your package.
The quick answer: The best Ada alternative for support teams whose customers call and text is Carly. Carly Phone puts an AI agent on your business number that answers calls and texts from your own FAQs, documents and website, already knows a returning customer from their email thread and CRM history, books and reschedules appointments on your real calendar, and hands off to a person in one shared inbox. You get going without an enterprise contract. Try Carly on your own number. For a like-for-like enterprise swap, Decagon and Sierra are the closest matches. Fin (formerly Intercom) and Salesforce Agentforce publish their prices, and Zendesk and Freshworks build the AI agent into the help desk you may already pay for.
Ada alternatives compared
Prices are in US dollars, checked against each vendor’s US site on October 1, 2026. Most enterprise AI agents don’t publish prices, and that’s part of the comparison.
| Tool | Pricing | Voice | How you buy | Best for |
|---|---|---|---|---|
| Carly | AI agents from $35/mo | Answers calls and texts on your number, books appointments, transfers | Sign up and connect your number | Support that arrives by phone, text and email |
| Ada (for reference) | Not published; annual contract metered by conversation | Ada Voice, plugs into your contact center; may not be in your package | Enterprise sales, demo first | Global enterprises with heavy chat and messaging volume |
| Fin (formerly Intercom) | $0.99 per outcome; Fin Voice $1.99 per voice outcome | Fin Voice, through sales | Trial on Intercom’s help desk, or sales | Chat and email teams that want a visible price |
| Zendesk AI Agents | Suite Team $55/agent annually; extra resolutions $1.50 to $2.00 | Telephony in Suite; generative AI for voice on Enterprise | Online or through sales | Teams already on Zendesk |
| Decagon | Not published; sales quote | Decagon Voice | Enterprise sales | Consumer brands running a bake-off |
| Sierra | Not published; outcome-based | Inbound and outbound, 55+ languages | Enterprise sales, 12-month contract | The largest consumer brands |

Why teams leave Ada
- No price until you’ve had the demo. Ada’s pricing page is a “Book a Demo” form with no rates. Vendr, which brokers software deals, puts the median Ada contract at $72,000 a year across 116 purchases, with deals running from about $36,000 to $300,000. Vendr also says Ada typically bills implementation separately, at $15,000 to $100,000 or more depending on scope.
- You pay per conversation, resolved or not. Ada’s customer terms sell a set number of Conversations, defined as all the messages between the bot and one customer in one channel within a 24-hour window. That definition counts messages exchanged, not problems solved. Conversations past your limit are billed at Ada’s “then-current rates,” a number the terms don’t state.
- Annual, upfront, and 10% more at renewal. Unless your order form says otherwise, Ada invoices annually upfront, renews automatically for another year unless someone gives 30 days’ notice, and states that fees for any renewal term “will be subject to a 10% increase for the same Services.”
- Voice is a contact-center project, and maybe an upsell. Ada Voice usually runs on Twilio numbers Ada’s team provisions and hands calls to people through platforms like Genesys, NICE CXone or Amazon Connect. Ada’s onboarding docs warn that voice “may not be included with your organization’s subscription package.”
- Buyers rate it far higher than the customers who talk to it. Ada averages 4.6 across 180 ratings from G2, PeerSpot and AWS Marketplace reviewers. On Trustpilot it’s a 1.7 across 21 reviews, mostly end customers describing bots that loop or stand between them and a person. A September 2026 reviewer wrote that it “seems to be purely an interface to prevent customers liaising with support teams.”
Here’s the math for Claire, who runs customer care at a home-fitness brand handling about 5,000 conversations a month, a third of them phone calls about deliveries, subscriptions and installation appointments. At Vendr’s median, Ada is $72,000 a year paid upfront: about $1.20 per conversation across 60,000 a year, counted whether or not the agent solved anything. Year two is $79,200 under Ada’s default renewal terms, before implementation or a voice package. And until a contact-center integration ships, those 1,700 or so monthly calls still hit the same phone tree. If your queue looks like Claire’s, get started with Carly.
1. Carly: best Ada alternative for support calls and texts
Carly is an AI assistant for businesses, and Carly Phone gives it a business line for calls and texts: a new local number or the one you already have. Give it what you’d load into Ada (help-center articles, return and shipping policies, documents, your website) and its voice agent answers the phone with it. A customer calls at 9 pm to move an installation appointment: Carly looks them up, finds an open slot on the real calendar, books it while they’re on the line and texts a confirmation link with their consent. A “where’s my refund” text gets your refund policy and timelines from your own knowledge, and when a question needs someone to check the account, Carly saves the details and hands the thread to your team. Photos customers text in, like a damaged delivery, get read and saved too.
Ada’s pitch is one reasoning engine across every channel. Carly’s is one assistant across the business. The same Carly works your email, calendar and CRM, so when Emily, who emailed last week about a late delivery, calls to follow up, Carly already has that thread and her CRM history instead of opening a fresh 24-hour conversation from zero. Try Carly and call your own number as a returning customer.
Handoff is built in. Calls and texts land in one shared inbox per number with transcripts, summaries, outcomes and voicemail recordings. Threads can be assigned and marked open, closed or unread, each has a “Carly replies / Human replies” switch, and on a live call Carly can transfer the caller to a teammate. Completed calls log to HubSpot, Salesforce or Dynamics 365, plus Carly’s built-in CRM.
What you set up in Carly:
- One number for calls and texts, with STOP and HELP opt-outs handled automatically. The same setup works as an AI receptionist or for SMS appointment booking.
- Call routing that rings your team all at once or in order, with business-hours and after-hours rules, phone menus and voicemail with transcripts.
- An email agent on your own domain, such as support@yourcompany.com, with a draft-for-review mode while you build trust.
- Thousands of apps. Carly connects to thousands of apps, including Zendesk, Salesforce, Intercom, Freshdesk, Gorgias, Shopify, Stripe, HubSpot and Slack.
Best for: Support teams where reschedules, policy questions and returning customers arrive by phone and text, and who want an AI agent live without an enterprise contract. Pricing: Free Zapier-style workflows; AI agents from $35/month. Setup: Connect your business number in Carly (the one you already have or a new one), then give it your knowledge, routing and handoff rules. The Carly team can help with setup. Set up Carly on your support line.
2. Fin (formerly Intercom)
Fin is the AI agent from the company formerly called Intercom, which renamed itself Fin in May 2026 and joined Salesforce in a roughly $3.6 billion deal that closed in September. It runs on Intercom’s help desk or on top of Salesforce, HubSpot, Freshworks and others. More in our Intercom pricing and Intercom alternatives guides.
Best for: Chat and email teams that want to see a price before signing anything. Pricing: $0.99 per outcome, charged at most once per conversation, plus help desk seats if you use Intercom’s. On another help desk there’s a 50-outcome monthly minimum. Fin Voice is sold through sales at $1.99 per voice outcome. Watch out for: Procedure handoffs and self-serve routings bill at the same $0.99 as resolutions, so an outcome isn’t always a solved problem.
3. Zendesk AI Agents (and Forethought)
If Ada hands off to Zendesk today, Zendesk’s own AI agents take a vendor out of the stack. They’re included in every Suite and Support plan, and since buying Forethought in March 2026, Zendesk also sells Forethought AI Agents by Zendesk, which run on other help desks too. See our Zendesk alternatives and Forethought alternatives.
Best for: Support teams already running Zendesk. Pricing: Suite Team $55 an agent a month billed annually ($69 monthly), Suite Professional $115 ($149). Each plan includes a small allowance of automated resolutions per agent, then $1.50 each committed or $2.00 pay-as-you-go. Forethought is a sales quote. Watch out for: Seats and resolutions are two meters that both grow, and generative AI for voice sits on Suite Enterprise.
4. Decagon
Decagon is a direct enterprise rival: AI agents that follow Agent Operating Procedures written in plain language across chat, email and voice, with Chime a named Decagon Voice customer. Bloomberg reported a $4.5 billion valuation in January 2026. More in what is Decagon AI and our Decagon AI alternatives.
Best for: Consumer brands running a formal bake-off against Ada. Pricing: Not published; sales quote. Watch out for: The same enterprise motion as Ada: a sales cycle, a custom contract and an implementation project.
5. Sierra
Sierra, the Bret Taylor and Clay Bavor company, sells AI agents across chat, SMS, WhatsApp, email and voice. By its own count, one in four of its customers has revenue over $10 billion. Compare it in what is Sierra AI, Decagon vs Sierra and our Sierra AI alternatives.
Best for: The largest consumer brands, with budgets to match. Pricing: Not published. Outcome-based, sold on 12-month contracts with pricing set by private offer. Watch out for: What counts as a billable outcome is negotiated per contract, so the unit price isn’t real until legal signs off.
6. Salesforce Agentforce
Agentforce puts the AI agent next to the customer record when Salesforce is your system of record, and Agentforce Voice takes it to the phone. With Fin now part of Salesforce too, one company sells two of the agents on this list.
Best for: Service teams standardized on Salesforce. Pricing: $2 per conversation for customer-facing agents, or Flex Credits at $500 per 100,000, where an action uses 20 credits and an Agentforce Voice action uses 30. A free Salesforce Foundations edition lets you start building. Watch out for: Every action is metered individually, so a multi-step support call burns several.
7. Freshworks (Freddy AI)
Freshdesk includes Freddy AI Agent on every plan, the simplest way on this list to price an AI agent without a sales call. It’s a help desk first, so the AI sits where your human team already works.
Best for: Mid-market teams that want the help desk and the AI agent on one self-serve bill. Pricing: Growth $19 an agent a month billed annually, Pro $55, Enterprise $89. Each includes the first 500 Freddy AI Agent sessions, and more cost $49 per 100. Freddy AI Copilot for human agents is $29 an agent a month annually ($35 monthly). Watch out for: A session is any interaction with the AI agent (an email session spans 72 hours), resolved or not. Phone runs through Freshcaller, a separate Freshworks product with its own pricing.
8. PolyAI
PolyAI is the voice specialist: enterprise “dialog agents” built for businesses that live on the phone, with named customers including PG&E, Fogo de Chão and UniCredit and a 99.9% uptime SLA on phone lines.
Best for: Phone-heavy enterprises that want a voice-first platform rather than a chat platform with voice added. Pricing: Per minute of voice agent use, including maintenance, improvements and 24/7 support. The rate isn’t published. Watch out for: Per-minute billing means long calls cost more whether or not they end in a resolution.
Matching the replacement to how your team uses Ada
- Customers call and text, and you want them answered, booked and handed to a person cleanly: Carly. It runs on your number and knows the customer from your email and CRM. Try Carly, or compare it with other AI answering services and AI customer service tools.
- Most of your volume is web chat and email, and you want a published price: Fin.
- Ada already hands off to Zendesk: Zendesk AI Agents, or Forethought if you want it on another help desk.
- An enterprise bake-off with an Ada-sized budget: Decagon or Sierra.
- Salesforce is your system of record: Agentforce.
- You want the help desk and the AI agent on one self-serve bill: Freshworks.
- The phone is your main channel at contact-center scale: PolyAI.
- Website chat on one tool, calls and texts uncovered: keep a chat-first pick for the site and put Carly on the business line.
Before Ada’s 30-day renewal notice window closes, put last month’s conversation report next to your phone system’s call log. Count the contacts that came in by phone or text, and how many were a reschedule, a policy question or a returning customer following up. If that’s a big share, get started with Carly and route those calls first. For the wider field, see the best AI agents for customer support and our AI customer service agent guide.
FAQ
What is the best alternative to Ada?

How much does Ada cost?
Ada doesn’t publish pricing; its pricing page books a demo. Vendr reports a median of $72,000 a year across 116 purchases, with deals from about $36,000 to $300,000, and implementation usually billed separately. Conversations over your contracted number bill at Ada’s then-current rates.
Can I cancel or change my Ada contract?
Under Ada’s standard terms, contracts are invoiced annually upfront, renew automatically for a year unless either side gives 30 days’ notice before the term ends, and renewal fees rise 10% for the same services. Your order form can override both, so check it. Carly can cover calls and texts on your business number while you sort out timing. Set up Carly on your support line.
Does Ada answer phone calls?
Yes. Ada Voice answers calls in 42 languages and hands off through contact-center platforms like Genesys, NICE CXone, Amazon Connect, Twilio Flex and Aircall, though Ada’s docs say voice may not be in your subscription package. Carly answers on the business number you already have, without a contact-center integration project. Try Carly.

For an address that is already connected, I open Manage access and click Connect next to anything missing. Repeat for every address. Carly connects to thousands of apps, so ask which other tools I want in too (CRM, Slack, Notion, and so on).
3. Check it worked: list my connected mailboxes and calendars and tell me every account you can see.
4. Then ask me what to hand off first, for example: "Check all my inboxes for anything that needs a reply today."See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
