Slack vs Intercom
Side-by-side trajectory, velocity, and editorial themes.
Slack rebuilds its developer platform around shipping in-channel AI agents.
Slack is well into a platform pivot, restructuring its CLI, Block Kit, and APIs around AI agent use cases. The 4.0.0 release in April formalized this with an agent-scaffolding command, sample agent apps, and a live-reloading dev workflow. Recent additions — streaming chat APIs, Card/Carousel/Alert blocks, and continued MCP server expansion — show the surface area for in-Slack agents widening fast.
The platform is shifting from 'agents can post messages' to 'agents are first-class UI citizens'. The new chat.startStream / chat.appendStream / chat.stopStream methods change what an agent reply looks like, and the Card and Carousel blocks hint at richer multi-turn agent flows. Security work on PKCE and optional scopes is keeping pace, which tells you third-party agent developers are the audience, not just first-party features.
Expect Slack to publish reference agents and likely a discovery or marketplace surface for agent apps within the next minor cycle, with streaming Block Kit becoming the canonical pattern shown in the docs.
Fin breaks out of the inbox: Intercom's AI now sells, not just supports.
Intercom is using its release cadence to push Fin from a support deflection agent into a broader commerce co-pilot, while continuing to polish inbox operations for human teammates. Recent shipping splits roughly in two: AI-side features that extend Fin's reach (Shopify selling, Guidance versioning, proxied content sync) and inbox-side workflow polish (WhatsApp voice notes, AAHT measurement, macro analytics exports).
The direction is clear: Fin is being repositioned from cost-saver to revenue-driver, with the Shopify integration making it answerable for catalog, pricing, and inventory rather than just helpdesk articles. Around it, Intercom is hardening the operational backbone (versioning, auditing, finer time accounting) that enterprise buyers will demand once an AI is closing carts. Expect the human-agent surface to keep getting incremental refinements while spark releases concentrate on Fin's job scope.
Next likely move is extending Fin's commerce skill set beyond Shopify, either to another storefront platform (BigCommerce, WooCommerce) or to post-purchase territory like returns and order status. A pricing or packaging change tied to Fin-driven conversion is the obvious follow-up if the Shopify pilot lands.
