“No-code” gets thrown around a lot in chatbot marketing. Here is what it should mean for this list: you can provision a business phone number, build a conversation flow visually, connect AI replies, and handle a real customer conversation over SMS, all without writing code or hiring someone who does.
That bar disqualifies more tools than you would expect. Several popular chatbot builders handle web chat or WhatsApp beautifully but need Zapier, custom webhooks, or a developer to touch SMS at all. They are not on this list. Every builder below supports genuine no-code SMS deployment as of September 28, 2026.
One more honest note on the “AI” in the title. Some of these tools give you true conversational AI that answers open-ended questions. Others give you an AI writing assistant that helps you draft messages, bolted onto keyword triggers. Both are useful, but they are not the same thing, and we say which is which for every pick.
How we ranked these
- True no-code SMS: number provisioning, inbound SMS, and visual flow building with no code required.
- AI depth: conversational AI that talks to customers beats writing assistants that help you draft.
- Keyword triggers and automation: the bread and butter of SMS bots.
- Human handoff: how easily a conversation escalates to a real person.
- Compliance tooling: consent capture, STOP handling, quiet hours.
- Pricing honesty: published prices and clear trial terms.

1. ManyChat: the most polished builder, with real conversational AI
ManyChat’s visual flow builder is the benchmark the others get judged against. Drag-and-drop flows, branching logic, and integrations with the usual business tools, all wrapped in an interface a non-technical person can learn in an afternoon. On the Pro tier ($39 a month, or $29 billed annually), you get SMS as a channel plus ManyChat AI, which handles open-ended customer questions instead of forcing every conversation through a rigid menu.
The free tier (25 active contacts, 2 channels) is fine for learning the builder, but SMS requires Pro. Billing is per active contact per month, not per message, with carrier fees on top at roughly $0.01 to $0.03 per message. If your audience lives on Instagram and you want SMS as the follow-up channel, nothing else on this list does the combo as well.
2. BotPenguin: conversational AI without the enterprise price
BotPenguin’s headline feature is that AI is included on every plan, including the free tier (around 1,000 messages a month) and the Little plan at $29 a month. Most competitors gate real AI behind their expensive tiers. Here you get a drag-and-drop builder, an AI that handles customer questions, live chat handoff to a human, and integrations with HubSpot, Salesforce, and Zoho among 40+.
The SMS catch: BotPenguin is not an SMS-native platform. You connect your own Twilio number, provision it on Twilio’s side, and build the bot in BotPenguin. Your per-message costs follow Twilio’s rates. That is a small extra setup step, but it also means your SMS pricing is transparent and portable. With GDPR, HIPAA, and CCPA compliance claims plus ISO certification and SOC 2 attestation, it is also one of the safer budget picks for sensitive conversations.
3. Avochato: pay-as-you-go with every AI feature included
Avochato takes a different approach to pricing. The usage-based plan costs $1 a month plus about $0.08 per message segment in the US and Canada, and it includes every AI feature: the AI chatbot, automated workflows, and keyword-activated responses. There is no tier where the AI suddenly appears. You also get SMS, MMS, RCS, voice, and live chat in one inbox.
That makes Avochato the most flexible pick here. A business with spiky volume (a seasonal shop, an event venue) pays almost nothing in quiet months and scales without changing plans. Keyword triggers fire automated responses, the AI handles open-ended replies, and conversations can escalate to a human agent in the same thread. Integrations include Salesforce, HubSpot, Slack, and Zapier.
The trade-off is that $0.08 per segment is expensive at high volume compared to the subscription plans above. Avochato rewards low and unpredictable volume. If you send tens of thousands of messages a month, do the math against SimpleTexting or EZ Texting first.
4. SimpleTexting: the reliable SMB workhorse
SimpleTexting is less of an “AI chatbot builder” and more of a superb SMS platform with automation and an AI assistant layered on. The AI Assist feature helps you write better messages; it does not hold conversations with customers. What it does brilliantly is the core SMS playbook: keyword opt-ins, auto-replies, drip campaigns, scheduled messages, and two-way conversations, all no-code.
Plans start at $29 a month for 500 credits with a 14-day trial (50 test messages). Credits roll over, which is unusually generous. It is owned by Sinch, so the infrastructure is serious, and it ships real 10DLC registration guidance. For the small business that needs reliable automated texting with light AI help rather than a full conversational agent, this is the pragmatic pick.
5. EZ Texting: the easiest workflows to build
EZ Texting’s strength is how fast a beginner goes from signup to a working automation. The Launch plan ($25 a month, or $20 annually) covers basic campaigns, while Boost ($75 a month) unlocks the workflow builder for drip sequences and triggered replies. AI Compose drafts your messages, and AI Reply on higher tiers helps handle responses.
The 30-day trial with 120 credits and no credit card is the most generous test drive on this list. Unlimited contacts and keywords on every tier make it friendly to list builders. Just remember the $5 monthly telecom fee on the Launch plan when comparing prices, and note that the deepest AI features sit on the higher tiers.
6. Textedly: the simplest keyword bots
Textedly is the minimalist of the group. There is no conversational AI here in the true sense; there are keyword triggers, drip campaigns, and conversation triggers that fire automated sequences. For a large share of small business use cases (text JOIN for a coupon, text INFO for hours and location), that is genuinely all you need.
The free account (50 messages, one keyword, no credit card, no time limit) makes it the cheapest way to test the concept. Paid plans start at $29 a month. An $8 monthly telecom surcharge applies on every plan, and the public API is still coming soon, so treat it as a closed but simple system.
What to check before you commit
Three questions separate the right pick from an expensive mistake. First, who provisions the number? SimpleTexting, Textedly, EZ Texting, and Avochato give you a business number directly. BotPenguin needs your own Twilio number. Second, what does the AI actually do? Ask for a live demo of an unscripted customer question, not the scripted tour. Third, what happens at 10x your current volume? Per-contact billing (ManyChat), per-segment usage (Avochato), and credit pools (SimpleTexting, EZ Texting) scale very differently.
Also confirm the compliance basics: automatic STOP handling, consent capture on opt-in forms, and 10DLC registration support. Our guides on TCPA consent and opt-out keywords cover what the law expects. This is general information, not legal advice.

Frequently asked questions
What is the best no-code AI SMS chatbot builder?
ManyChat has the most polished builder and true conversational AI on its Pro tier. BotPenguin is the best value, with AI included even on the free plan. Avochato is the most flexible with pay-as-you-go pricing. The right pick depends on your volume and whether your audience lives on social media.
Can I really build an SMS chatbot with zero coding?
Yes, with the six tools on this list. You can provision a number, build flows visually, set up keyword triggers, and connect AI replies without writing code. You need a developer only for custom integrations or logic these builders do not offer.
What is the difference between an AI chatbot and keyword automation?
Keyword automation matches incoming texts to preset triggers (text PIZZA, get the menu) and sends scripted replies. A conversational AI chatbot understands open-ended questions (“do you have gluten-free options near me?”) and responds naturally. ManyChat, BotPenguin, and Avochato offer the latter; Textedly and SimpleTexting lean toward the former with AI assistance.
How do conversations hand off to a human?
All six builders support it, but the mechanics differ. ManyChat, BotPenguin, Avochato, and Heymarket-style inboxes route to a live agent view with full conversation history. Simpler tools notify you and pause the automation. Test the handoff before launch; a bot that traps frustrated customers is worse than no bot.
Do these builders handle opt-outs automatically?
Yes, the reputable ones do. STOP, QUIT, CANCEL, and similar keywords must immediately suppress future marketing messages, and all six platforms handle that automatically. What they cannot do for you is collect proper consent in the first place or register your 10DLC campaign. Those are your responsibility.
Which builder is best for appointment-based businesses?
Avochato’s AI chatbot with keyword triggers works well for booking flows, and SimpleTexting’s drip campaigns handle reminder sequences reliably. For a deeper look at reminder automation, see our guide to AI SMS appointment reminders.
