Slack gets smarter: New AI tools summarize chats, explain jargon, and automate work

Slack is rolling out an extensive array of artificial intelligence features that promise to eliminate routine tasks and turn the messaging platform into a central hub for enterprise productivity, marking owner Salesforce’s direct challenge to Microsoft’s workplace AI dominance.

The announcements, set to roll out over the coming months, include AI-powered writing assistance embedded directly into Slack’s canvas feature, contextual message explanations, automated action item identification, and enterprise search capabilities that span multiple connected business applications. The moves come as Salesforce simultaneously restricts external AI companies from accessing Slack data, creating a walled garden approach that mirrors broader industry trends toward platform consolidation.

“Unlike some AI tools that sit outside the flow of work, Slack’s AI shows up where work happens – across conversations, decisions, and documentation,” said Shalini Agarwal, Vice President of Slack Product at Salesforce, in an exclusive interview with VentureBeat. “The key differentiator is context, which comes in the form of structured and unstructured data in Slack.”

The timing underscores intensifying competition in the $45 billion enterprise collaboration market, where Microsoft’s Teams platform and its Copilot AI assistant have gained significant traction against Slack since Salesforce’s $27.7 billion acquisition of the messaging service in 2021. Google is also pushing its Duet AI across Workspace applications, creating a three-way battle for corporate customers increasingly focused on AI-driven productivity gains.

How Slack’s contextual AI works inside workplace conversations

Slack’s new capabilities depart from traditional AI assistant models that require users to actively prompt for help. Instead, the platform will proactively surface relevant information and automate routine tasks within existing workflows.

The AI writing assistance, launching soon within Slack’s canvas feature, will allow teams to automatically generate project briefs from conversation threads, extract action items from brainstorming sessions, and reformat meeting notes into structured updates. When combined with Slack’s existing AI-powered meeting transcription in huddles, the feature creates an end-to-end documentation workflow.

“AI needs to feel easy and seamless, and you shouldn’t have to work hard to use it,” Agarwal told VentureBeat. “Since the release of AI in Slack, customers have summarized more than 600 million messages, saving a collective 1.1 million hours across users.”

Perhaps more intriguingly, Slack will introduce contextual message explanations that activate when users hover over unfamiliar terms, acronyms, or project references. The feature draws from the organization’s unique vocabulary and conversation history stored within Slack, potentially solving a persistent onboarding and cross-team collaboration challenge.

“Ever hit an unfamiliar acronym or bit of jargon in a Slack message? That moment of confusion, of searching or asking, slows everything down,” the company noted in its announcement.

Enterprise search becomes the new battleground for workplace data

The centerpiece of Slack’s AI strategy is enterprise search, now generally available, which allows users to query information across connected applications including Salesforce, Microsoft Teams, Google Drive, Confluence, and Box from a single interface within Slack.

The capability addresses a persistent productivity drain in modern workplaces, where employees spend an estimated 41% of their time on repetitive tasks like searching for information across disconnected systems, according to Slack’s research. By positioning Slack as the unified search interface for enterprise data, Salesforce is making a bold play to become the primary workspace hub for knowledge workers.

Rather than building point-to-point connections between applications, Slack is positioning itself as the universal translator for workplace information. The approach acknowledges a harsh reality: most organizations have accepted that their data will remain scattered across dozens of applications, but they desperately need a better way to find and use that information.

For IT departments, Slack promises minimal deployment complexity. “Generally, it should be a light lift for IT teams,” Agarwal said. “Connectors will be out of the box as they become available. Once admins enable an app, and users authenticate to it, results will be available immediately.”

Why Salesforce is blocking AI competitors from accessing Slack data

Even as Slack opens its search capabilities to customers’ connected applications, Salesforce has been aggressively restricting how external AI companies access Slack data. In May, the company amended its API terms of service to prohibit bulk data exports and explicitly ban using Slack data to train large language models.

The move affects third-party AI search companies like Glean, which had been indexing Slack conversations alongside other enterprise data sources to provide unified search experiences. Under the new restrictions, such companies can only access Slack data through real-time search APIs with significant limitations.

Salesforce is making a calculated gamble. By restricting access to Slack data, the company is betting that its own AI capabilities will prove superior to external alternatives. But enterprise customers have consistently shown they prefer choice and flexibility over forced vendor lock-in. If competing AI platforms deliver significantly better results using data from other sources, Salesforce risks pushing customers toward alternative messaging platforms that offer more open integration.

The restrictions underscore how valuable workplace conversation data has become. With over 5 billion messages exchanged weekly on Slack, the platform contains what Agarwal describes as “the history of your company, and all the information across teams and projects.”

This conversational data offers something unique in the enterprise software landscape: unstructured, context-rich information about how work actually gets done, rather than formal documentation about how it should get done.

Enterprise security concerns drive AI trust and compliance features

Salesforce has built its AI capabilities around what it calls “the Einstein Trust Layer,” emphasizing that customer data never leaves the company’s infrastructure or trains external AI models. The approach addresses enterprise concerns about data sovereignty that have slowed AI adoption in regulated industries.

“Protecting our customers’ data is Slack’s top priority,” Agarwal said. “Customer data stays in-house, Slack does not share customer data with LLM providers, and Slack does not use customer data to train LLMs.”

The platform’s AI features inherit Slack’s existing enterprise-grade security controls, including support for FedRAMP compliance, encryption key management, and international data residency requirements. Search results automatically respect existing user permissions across connected applications, preventing unauthorized data exposure.

Early customer results show measurable productivity gains from AI features

Early customer results suggest meaningful productivity gains, though the sample size remains limited. Salesforce’s internal engineering team reports that its AI agent has handled over 18,000 conversations across 3,500 users in six months, potentially saving the equivalent of eight full-time employees worth of work annually.

Other customers report similar metrics. OpenTable handled 73% of restaurant web queries using Salesforce’s Agentforce AI in just three weeks, while payment processor Engine reduced average handle time by 15% and projects $2 million in annual cost savings.

These early results, while promising, should be viewed with appropriate skepticism. Productivity measurements in enterprise software often suffer from selection bias, where only the most successful implementations generate public case studies. The true test of Slack’s AI capabilities will come as adoption scales beyond early adopters to mainstream enterprise customers with more complex, less standardized workflows.

How Slack’s AI strategy compares to Microsoft Copilot and Google Workspace

The announcements position Slack more directly against Microsoft’s comprehensive AI strategy, which includes Copilot integration across the Office 365 suite and Teams platform. Microsoft’s approach has gained significant enterprise traction, with the company reporting that Copilot adoption is driving workplace productivity gains across its customer base.

However, Slack’s conversational-first approach may offer advantages for organizations where informal communication drives decision-making. “Slack’s conversational interface and rich context make it a very natural home for AI agents,” Agarwal noted.

The company is also extending its reach through new pricing strategies, including significant government discounts that mirror Google’s competitive tactics. In May, Salesforce announced up to 90% discounts for federal agencies through November, replacing fragmented agency-by-agency negotiations.

The future of autonomous AI agents in workplace collaboration

Agarwal’s vision extends beyond current capabilities toward autonomous AI agents that can execute complex workflows across multiple systems. “Our vision for an agentic work operating system is that everyone can bring AI, agents, customer data, team collaboration, and connected systems into a single place so they can work faster and smarter,” she said.

The company recently launched Agentforce in Slack, bringing task-specific digital teammates that can update CRM records, post in channels, and assist with employee onboarding. Early results show Salesforce’s sales team saving 66,000 hours annually through AI assistance with deal insights and executive briefings.

As AI capabilities become table stakes for enterprise software, Slack’s success may depend on execution rather than innovation. The platform’s strength lies in its position as the de facto standard for workplace messaging, providing the conversational context that makes AI responses more relevant and actionable.

Whether this contextual advantage proves sustainable against Microsoft’s integrated ecosystem and Google’s search expertise remains an open question. But for now, Salesforce is betting that the future of work happens in conversations — and that whoever controls those conversations controls the workplace AI market.

The new AI features will be included in all paid Slack plans, with advanced capabilities reserved for higher-tier subscriptions. Enterprise+ customers will receive the full AI experience, including enterprise search and governance controls designed for large-scale deployment.

For enterprise decision-makers evaluating AI collaboration tools, Slack’s approach offers a compelling alternative to Microsoft’s suite-wide integration strategy. The question is whether contextual AI within conversations can compete with the broader productivity gains promised by AI assistants embedded across entire software ecosystems.
