Slack - 2026 Pricing, Features, Reviews & Alternatives

Slack is a cloud-based AI work platform that consolidates people, projects, knowledge, and tools into a single interface. Teams communicate through organized, searchable channels grouped by project, topic, or team; exchange direct messages and threaded group conversations; and collaborate with external partners, clients, and vendors in real time via Slack Connect — without leaving the platform. Built-in audio and video huddles include AI-generated transcription and meeting notes. Async communication is supported through Clips, a video and audio messaging tool. Canvases provide shared documents, while Lists enable task and project tracking directly within conversations. Workflow Builder supports no-code and code-based automation for recurring processes such as stand-ups, approvals, and project updates. Over 2,600 third-party app integrations — including Salesforce, Google Drive, GitHub, Jira, Workday, and Microsoft apps — keep work consolidated in one place. Available on desktop (Windows, Mac), mobile (iOS, Android), and web browser, with Enterprise Grid available for large organizations requiring cross-workspace management and advanced security controls.

AI capabilities are embedded throughout the platform. An AI assistant understands workspace context and can summarize threads and files, draft content, answer questions, analyze documents, find and schedule meetings, and trigger actions across connected apps. AI-powered enterprise search uses natural language queries to surface cited answers across messages, files, canvases, and connected third-party apps. Channel and thread summaries, daily recaps, huddle notes, message translation, and conversational workflow generation are all available as AI features. Agentforce integration brings AI agents built on Salesforce directly into channels, threads, and direct messages, with access to real-time messages, files, CRM data, and connected app data. Out-of-the-box agent apps include Adobe Express, Asana, Box, Cohere, Workday, and Writer. All AI features run on Slack-controlled infrastructure; large language models are hosted in Slack-controlled virtual private clouds, and customer data is not used to train LLMs.

Enterprise-grade security and compliance controls include FedRAMP Moderate authorization, admin-controlled encryption key management (Enterprise Key Management), data residency controls, and compliance exports. The platform serves teams of all sizes across technology, retail, marketing, finance, sales, engineering, customer support, and general enterprise sectors, with more than 200,000 organizations worldwide using the platform.
