Build a Slack AI Agent That Answers Questions (Step-by-Step Tutorial)

1. Question Base

Question Base is a Slack-native AI answer agent built to provide enterprise teams with verified answers directly within Slack. Unlike general-purpose AI tools that simply summarize past conversations, Question Base connects to your trusted documentation sources - including Notion, Confluence, Salesforce, Google Drive, Zendesk, Intercom, and more. This ensures that answers are accurate and sourced in real time. Setting it up is straightforward: install the app from the Slack App Marketplace, invite the bot to your channels using /invite @questionbase, and link your knowledge sources. No engineering expertise is required.

Integration Capabilities

Question Base seamlessly integrates with a variety of enterprise platforms, pulling information from the tools your team already relies on. For example:

• Notion: Syncs pages and databases.

• Confluence: Accesses spaces, pages, and blog posts.

• Salesforce: Retrieves accounts, cases, contacts, and opportunities.

This deep integration ensures that employees receive answers directly from official, trusted documentation, rather than AI-generated summaries of Slack conversations. Whether used in public channels, private channels, or direct messages, Question Base offers the flexibility to support different teams, such as HR, IT, and operations. These integrations enable precise, context-aware responses tailored to your organization’s needs.

Accuracy & Contextual Responses

To maintain accuracy, Question Base incorporates human oversight. While the AI drafts initial responses, teams can review, edit, and approve them before they’re shared. Each response includes exact quotes and source annotations from your connected documents, so employees can see where the information originated. If a question can’t be answered, it’s escalated to an expert for resolution.

During a typical 30-day pilot, Question Base managed to auto-answer 35% of repetitive questions, saving internal experts over 6 hours per week on average[1]. The platform boasts a 4.8/5 answer accuracy score and an average response time of just 3.2 seconds[1].

"Since we started using QB we haven't used our Google support docs. And if I go on vacation or sick leave, I feel comfortable that QB will just take over." - Linn Stokke, Online Events & Marketing Specialist, Ticketbutler[1]

With its focus on both accuracy and efficiency, Question Base goes beyond simple automation to deliver real value for enterprise teams.

Enterprise Features

Security and customization are at the core of Question Base. The platform is SOC 2 Type II Certified and provides encryption both at rest and in transit. For organizations with stringent data residency requirements, it also offers on-premise deployment. Teams have full control over what content the AI can access and can tailor the AI’s tone, behavior, and escalation workflows to suit specific channels. For instance, your IT team can set up a different response style and knowledge base than your HR team, all within the same Slack workspace.

For larger organizations, Question Base offers additional features such as white-labeling and support for multiple Slack workspaces through its Enterprise tier, ensuring it scales with your needs.

Knowledge Management

Question Base doesn’t just answer questions - it also helps structure and maintain your team’s knowledge base. When experts reply to questions in Slack threads, the tool identifies recurring patterns and suggests adding those answers to the knowledge base with a single click. It also tracks unanswered questions and provides analytics on resolution rates, automation success, and areas where the AI struggles to respond. This helps knowledge managers pinpoint content gaps and improve the system over time.

The result is a living FAQ that grows and adapts with your team’s needs, eliminating the need for periodic manual updates. By reducing the time spent searching for information, Question Base delivers measurable productivity gains. At $8 per user per month, it’s also a cost-effective alternative to Slack AI’s $18 per user per month, offering deeper integrations and advanced knowledge management features[1].

2. Slack AI

Slack AI is seamlessly embedded into Slack, offering features like integrated search, conversation summaries, and daily recaps. It delivers answers while keeping all data securely within the Slack environment. Let's dive into its integration, accuracy, enterprise-level features, and approach to knowledge management to better understand its strengths and limitations.

Integration Capabilities

Slack AI builds on Slack's existing framework, drawing exclusively from its own ecosystem and select external tools. It uses data from messages, threads, channels, and files within Slack. For teams on Business+ and Enterprise plans, it can extend its search to external tools integrated through Enterprise Grid, such as Google Drive or GitHub. However, it stops short of connecting to platforms like Notion, Confluence, or Salesforce, where verified documentation often resides. This means Slack AI only retrieves content already shared within Slack, leaving external verified sources out of its scope.

Accuracy & Contextual Responses

The AI generates responses using historical Slack conversations and shared files. While this works well for summarizing discussions or providing recaps, it lacks human oversight. Without a verification layer, responses may include outdated or unverified information. Unlike specialized tools that pull answers from trusted, up-to-date sources, Slack AI is limited to the data already within its Slack environment. This can be a hurdle for teams that require precise, compliant, and verified information.

Enterprise Features

Slack AI is offered as an add-on for paid Slack plans, priced at $18 per user per month [1] [2]. Features such as the "Channel Expert" agent and organization-wide search are accessible only on higher-tier plans. While Slack AI prioritizes data privacy by keeping information within Slack, it lacks the customization options found in more specialized tools. For example, you can’t adjust the AI’s tone or behavior for specific channels, nor can you implement escalation workflows for unresolved queries.

Knowledge Management

Slack AI shines when it comes to summarizing existing conversations, but it falls short in organizing or updating new information. If an expert answers a question in a thread, that answer remains buried in the chat history unless someone manually documents it. Slack AI doesn’t capture or structure new knowledge - it simply retrieves what’s already been said. For teams aiming to build a self-improving knowledge base from daily interactions, this limitation can be a roadblock. While Slack AI helps locate past information, it doesn’t actively evolve or systematize that knowledge over time.

3. Guru

Guru takes a distinct approach to knowledge management by focusing on curated, expert-approved answers. Unlike tools such as Question Base that leverage generative AI, Guru relies on "Guru Cards" - short, verified snippets of information that are delivered directly in Slack. These cards are reviewed and approved by subject-matter experts, ensuring reliable and accurate knowledge sharing. This makes Guru particularly well-suited for mid-to-large teams that prioritize governed, dependable information in their workflows.

Integration Capabilities

Guru seamlessly integrates with popular enterprise tools like Salesforce, Zendesk, Google Workspace, and Microsoft 365, enabling unified search across connected platforms. When a question is asked in Slack, Guru's Enterprise AI Search scans these integrations and suggests relevant Guru Cards or synthesized answers that pull from multiple sources. Teams can even create or update cards directly from Slack, eliminating the need to switch between tools to maintain the knowledge base. This streamlined integration ensures that knowledge is always accessible without disrupting the natural flow of work. Unlike tools that depend solely on historical chat data, Guru’s method centers on delivering vetted, curated content.

Accuracy & Contextual Responses

Guru stands out by prioritizing verified answers over generative content. Each Guru Card is assigned to an expert for review, and the platform automatically prompts re-verification to keep the information accurate and current. When Guru's AI suggests an answer, it includes citations linking back to the original verified source. This transparency addresses common issues with chat-based AI, like outdated or unreliable information buried in threads. For industries where compliance and accuracy are critical, such as healthcare or finance, this governance model is a key advantage. By focusing on rigorously verified content, Guru ensures that its Slack-surfaced answers remain trustworthy and up to date.

Enterprise Features

Guru is packed with enterprise-level capabilities, making it a strong choice for large organizations. Features include SSO/SAML for secure access, SCIM provisioning for user management, granular permissions, and content lifecycle controls. These tools are tailored for Slack-centric workflows. Pricing starts at roughly $15 per user per month, with higher-tier plans adding advanced analytics and governance options. Guru also provides insights on card usage and identifies content gaps, helping teams refine their knowledge base over time. While its pricing may be higher than some lightweight alternatives, the cost reflects its robust security and customization features designed for enterprise needs.

Knowledge Management

At its heart, Guru organizes information into Cards, which are grouped into Collections. This structured approach offers a clear alternative to the often chaotic nature of Slack threads. When a new question is asked, Slack discussions can be transformed into reusable Guru Cards, which the system will suggest for similar queries in the future. This process turns informal Slack conversations into a continuously improving knowledge base without requiring experts to document answers manually. However, Guru’s emphasis on concise, card-based knowledge may not appeal to teams that prefer lengthy, document-style resources. By converting casual exchanges into structured knowledge, Guru supports scalable documentation that grows alongside your team’s needs.

4. ClearFeed
