Chat Support Software for Busy Support Teams

1. momo: for teams that want knowledge-grounded AI and a human inbox

It is a fit for store owners and startup support leads who spend too much time repeating answers about products, shipping, returns or company policies. It uses the business’s own content: a website crawl, PDFs, Word files, plain text and Q&A pairs. The AI retrieves relevant passages, drafts a response and checks that draft against those sources. When it is confident, the visitor receives an answer with citations. When it is not, the visitor is told it is unsure and a ticket is opened for the team.

The concrete distinction is that the shared helpdesk inbox is included on every plan, including Free. This makes it a chat support software option for teams that want AI answers alongside human follow-up. A teammate can take over a conversation live, and the business chooses what details the handoff collects. A human response can later be saved as approved knowledge through the Teach step. Current live channels are the website widget, email and Slack; Shopify is in preview, so do not choose this on the assumption that it can look up orders or take Shopify actions.

Plans have a flat fee and include a set number of AI conversations. There is no per-resolution fee or credit pack. Paid plans allow up to 25 AI replies in a conversation, while Free allows up to 10. The hosted service is available, and the same code can be self-hosted under the PolyForm Internal Use License. The product is source available, not open source. That license allows a company to run and modify the code for its own use, but not to resell it, host it for others or redistribute it. The code is source available, not open source.

2. Help Scout: for small teams that prefer a shared workspace

Help Scout suits teams that want to work together on customer conversations and offer live chat on a website or in an app. Its Free plan includes five users, one inbox and one Docs site. AI Answers uses knowledge-base content and custom sources to provide answers. Help Scout also prices an AI resolution as a conversation resolved by AI Answers without human assistance, so teams comparing AI costs should account for that usage unit rather than looking only at the inbox plan.

The concrete differentiator is the combination of a shared workspace and website or in-app live chat, with AI Answers drawing on knowledge content and custom sources. Help Scout describes its Inbox as bringing email, SMS, social, chat and voice together. Compare the channels and workspace limits your team needs, and account for AI resolutions when estimating usage. If you are comparing it with a flat conversation allowance, make sure your expected AI-resolved volume is part of the calculation.

3. Chatwoot: for technical teams that want to self-host

Chatwoot is worth considering when your team wants a support inbox that brings live chat, email and social conversations together and has the engineering capacity to run its own infrastructure. Chatwoot offers both a self-hosted edition and a cloud option. That comparison lists cloud prices per agent: $19 per agent per month for Startups, $39 for Business and $99 for Enterprise. Those are per-agent figures, unlike a flat plan fee.

The concrete trade-off is the work of self-hosting. Self-hosting calls for DevOps expertise and involves Docker, PostgreSQL and Redis. Teams that manage the deployment also take responsibility for its infrastructure. Chatwoot’s paid plans include monthly Captain AI credits, and additional credits are billed separately. Its listed allowances differ by plan, and the stated additional-credit rate is $20 per 1,000. Check whether that credit-based approach suits your team’s usage before comparing it with conversation-based pricing.

4. Zendesk: for teams building configurable bot flows

Zendesk may suit teams that need live chat alongside business and social channels and want to design conversational flows for different scenarios. Its drag-and-drop bot builder lets non-developers create chat flows. Bots can collect customer information before handing a query to a live agent, helping carry details into the human conversation.

The concrete differentiator is the flow builder and its ability to collect details before handoff. That can matter when agents need a little context before they take over, rather than starting each exchange from scratch. Zendesk’s live chat material also describes in-app and website chat, chatbot builders and built-in social messaging integrations in a free trial. AI agents are billed around automated resolutions, with plans including an allowance that depends on plan and agent count. Pricing and included usage depend on the plan, so compare the expected volume and escalation pattern against the resolution unit before committing.

5. Tidio: for teams bringing website chat, email and Messenger together

Tidio is a candidate for teams looking for website live chat alongside email and Facebook Messenger. Tidio’s free plan allows live-chat conversations with up to 50 users, and its Communicator and Chatbots plans have a seven-day free trial.

The concrete point to check is the free-plan user limit against the kind of usage your team expects. A user limit is not the same thing as a monthly AI conversation allowance, so confirm that the plan’s terms match your contact volume and the work you want the software to handle. Consider its website chat, email and Messenger channels alongside the free-plan limit and trial. They do not establish PDF support, source citations in AI answers or what happens when a bot is unsure. If those are requirements, ask specific questions during evaluation rather than assuming that live chat and chatbot features work the same way across tools.

How to choose by team size, channels and budget

Start with the work that lands in your queue, not with a feature checklist. If customers mainly need to talk to an agent in real time, prioritize website chat, routing and a clear way to continue the conversation when the first agent is unavailable. Zendesk’s bot flows can collect customer details before a live-agent handoff; Help Scout offers live chat on a website or in an app. Those workflows are different from an AI that answers from business knowledge before a human gets involved.

If the same questions arrive repeatedly, check what material the AI can use and what it does when the answer is uncertain. A confident answer should have a basis your team can review. A fallback should make it clear who receives the question and what details they get. With momo, the AI checks its draft against retrieved business sources, cites confident answers and opens a ticket when it is unsure. The shared inbox is included on every plan, and teammates can take over live. For more on AI live chat for customer support, see how to evaluate the answer and handoff workflow.

For a small team, compare the number of people who need access with the inbox and knowledge limits on the plan. Help Scout’s Free plan has five users, one inbox and one Docs site. momo Free is a one-time allowance, not a recurring monthly allowance: it includes 30 AI conversations, one agent and one team member. Paid plans include monthly AI conversation allowances. Do not compare those numbers directly with Chatwoot’s per-agent cloud prices or Help Scout’s per-resolution AI unit; each measures a different part of the work.

Channels can rule out an otherwise suitable tool. List where customers contact you today, then distinguish live channels from features in preview or coming soon. If self-hosting is important, account for the technical work as well as the license: Chatwoot self-hosting calls for DevOps expertise and involves Docker, PostgreSQL and Redis. See more about self-hosting live chat. momo can also be self-hosted for a company’s own use, under its source-available license. Finally, test how the handoff feels to the person asking for help and the teammate receiving it. A good choice leaves neither side guessing what happens next.
