Slack vs Zoho Notebook
A side-by-side editorial comparison of Slack and Zoho Notebook — release velocity, themes, recent moves, and the top alternatives to consider.
Slack vs Zoho Notebook: at a glance
What is Slack?
Slack now hosts any A2A agent without Slack-specific code.
Slack's developer channel is almost all agent plumbing. On 10 November Slack became an A2A (Agent2Agent) client: a team hosts its own agent, publishes an Agent Card, and Slack calls it when people talk to it, with no request URL, event handling or Slack-specific logic. This follows Slackbot skills managed through Web API methods, a Slack CLI that points coding agents to the Slack MCP server, and a new requirement that Work Objects embeds allow the slack-mcps.com frame ancestor.
What is Zoho Notebook?
Zoho Notebook layers AI onto a note app, but its feed runs heavy on marketing.
Zoho Notebook's tracked feed is a slow, marketing-heavy blog — digital-minimalism essays, year-in-review recaps, and seasonal posts interleaved with a few genuine product announcements. The real signal in the window is the product's AI buildout: Notebook AI (an in-app assistant) and AI Meeting Notes, plus periodic Apple-OS support refreshes. Cadence is low and entries span more than a year.

Slack
6.3COMMSCOLLAB
Slack now hosts any A2A agent without Slack-specific code.
◆ Current state
Slack's developer channel is almost all agent plumbing. On 10 November Slack became an A2A (Agent2Agent) client: a team hosts its own agent, publishes an Agent Card, and Slack calls it when people talk to it, with no request URL, event handling or Slack-specific logic. This follows Slackbot skills managed through Web API methods, a Slack CLI that points coding agents to the Slack MCP server, and a new requirement that Work Objects embeds allow the slack-mcps.com frame ancestor.
◆ Where it's heading
Slack is lowering the cost of putting outside agents in front of its users: first skills as code, then MCP pointers for coding agents, now a standard protocol in place of the Slack app model for agents. The platform is positioning itself as the place where agents built anywhere meet the people who use them.
◆ Prediction
Expect more A2A follow-ups, such as agents appearing in Slackbot or skills surfaces and richer Agent Card features, given how fast the agent releases have stacked up since October.
Zoho Notebook
2.5COLLAB
Zoho Notebook layers AI onto a note app, but its feed runs heavy on marketing.
◆ Current state
Zoho Notebook's tracked feed is a slow, marketing-heavy blog — digital-minimalism essays, year-in-review recaps, and seasonal posts interleaved with a few genuine product announcements. The real signal in the window is the product's AI buildout: Notebook AI (an in-app assistant) and AI Meeting Notes, plus periodic Apple-OS support refreshes. Cadence is low and entries span more than a year.
◆ Where it's heading
The product's arc is a steady move from manual note-taking toward an AI-assisted workspace, with the assistant and meeting-notes features as the substantive steps amid a stream of content marketing. Because the feed mixes promotion with releases, the genuine shipping signal is sparse and easy to lose in the noise.
◆ Prediction
Expect continued AI feature extensions (capture, summarization, organization) and routine Apple-OS support updates, with marketing posts dominating volume. Deeper integration into the wider Zoho suite is the likely direction, though the slow feed makes timing hard to call.
