Key takeaways

• An AI chatbot is only as good as the content it learns from. Pick a tool that trains on your website, documents and FAQs, and lets a person take over.

• Pricing models differ: per conversation, per message credit, per seat, per resolution or flat. The cheapest entry price is not always the cheapest at your volume.

• Channel coverage matters more for a small business than model names. If your customers use WhatsApp and Instagram, check those first.

• Very few vendors publish a clear bring-your-own-key option. We could not verify it for the other tools in this guide.

What is an AI chatbot for small business?

An AI chatbot reads a customer's question and writes an answer in natural language, using your business content as its source. Unlike a menu-driven bot, it handles questions you did not script. For a small business the typical jobs are answering common questions, qualifying leads, booking appointments and handing hard cases to a person.

What should a small business look for?

• Training on your content: website pages, PDFs and FAQs, not generic answers.

• Human handover: a shared inbox where your team can step in.

• Channels: WhatsApp, Instagram, Messenger and your website.

• Predictable pricing: know what happens when conversations grow.

• Model choice: the ability to change the AI model or use your own key as prices and quality change.

Best AI chatbots for small business at a glance

1. BossReply: best for small teams that sell on chat apps

BossReply puts WhatsApp, Instagram, Messenger, Telegram and website chat in one inbox and adds an AI agent trained on your own content. You can choose the model (OpenAI, Claude, Gemini or Grok) and bring your own key to pay your AI provider directly. Instagram comment-to-DM sends the DM automatically and does not post a public reply. Plans are $14, $29 and $69 per month with yearly billing saving up to 17%, and they are not priced by stored contacts.

2. Tidio: best for website-first stores

Tidio combines live chat with its Lyro AI agent and Flows. The free plan includes 50 billable conversations; Starter is $24.17 and Growth starts at $49.17 per month. Lyro is an add-on from $32.50 per month, so budget for it. Messenger, Instagram, WhatsApp and email are listed across plans. We could not verify bring-your-own-key or comment-to-DM.

3. Chatbase: best for answering from documents

Chatbase trains on your files and pages and offers a helpdesk inbox and voice. Hobby is $32 per month for 700 message credits, Standard $120 for 4,000 and Pro $400 for 15,000, with a 7-day trial and no free plan. WhatsApp, Messenger and Instagram integrations are listed on every plan. Removing the "Powered by Chatbase" badge costs $1,188 per year. We could not verify bring-your-own-key.

4. Botpress: best when you have a developer

Botpress is a flexible agent builder. The free plan allows 100 conversations; Plus is $150 per month with 250 conversations, $25 of AI usage and WhatsApp; Team is $750 for 1,500 conversations. Extra conversations cost $65 per 100 on Plus, and AI usage passes through at provider prices. Its Instagram channel handles DMs only, not comment-to-DM.

5. Landbot: best for guided flows

Landbot builds conversational flows, with WhatsApp as a focus. Free allows 100 chats on web only without AI; Starter is €32 per month on annual billing with 500 chats and 100 AI chats. Professional is €80 annual and a WhatsApp number adds €100 per month on that plan, plus Meta costs and €0.05 per message.

6. Freshchat: best for support teams

Freshchat is free for up to 10 agents and paid plans run $19, $49 and $79 per agent per month billed annually. The Freddy AI agent includes 500 free sessions once per account, then $49 per 100 sessions. Instagram, Facebook, SMS and WhatsApp are on Growth and above.

7. Intercom and Zendesk: best for larger helpdesks

Intercom charges $29, $85 or $132 per seat per month, and its Fin AI agent costs $0.99 per resolution. Intercom staff have said Instagram comments are not supported, only DMs. Zendesk starts at $19 per agent on Support Team and $55 on Suite Team, with AI agents billed at $1.50 to $2 per automated resolution. Both suit teams with several agents more than a one-person shop.

8. HubSpot: best if you already use HubSpot

HubSpot's Service Hub has a free tier with limited bots. Its Customer Agent is reported at around 50 credits per resolved conversation, which is about $0.50. It needs a Professional or Enterprise Service Hub plan, which also carries onboarding fees.

9. respond.io: best for messaging-first teams

respond.io starts at $79 per month for Starter and $159 for Growth, with AI agents from Growth. It is priced by monthly active contacts, with overage of $12 per 100 on Growth. See our best WhatsApp chatbots guide for more on the WhatsApp side.

How do you choose the right plan size?

1. Count your monthly conversations, not your followers.

2. List your channels and make sure each is supported on the plan you want.

3. Test the AI with ten real customer questions from your inbox.

4. Check what happens at the limit: overage fees, a paused bot or a forced upgrade.

5. Read the cancellation terms before you pay for a year.

How much does an AI chatbot cost for a small business?

Costs have two parts: the platform and the AI. A flat plan covers the platform for a fixed monthly fee. Per-conversation and per-resolution plans scale with traffic, so they feel cheap while you are small and larger as you grow. The AI itself costs fractions of a cent per reply on small models: using published API prices, a six-turn conversation on a low-cost model such as OpenAI's gpt-6-luna costs about $0.002, while a premium model can cost several cents. That is why bring-your-own-key matters when you can choose a cheaper model. For a deeper look see our chatbot pricing models guide.

Mistakes to avoid

• Letting the AI answer pricing, refunds or legal questions without human review.

• Training the bot on outdated pages.

• Choosing a tool for one channel when customers use three.

• Ignoring how conversations are counted by each vendor.
