What is Count?

Count's agent now shows the chain of cells and assumptions behind every answer it gives.

Count is a data-canvas analytics tool organized around an AI agent. Its late-October release added Reasoning Chains, which link each claim and chart in an agent answer back to the cells, sources and assumptions behind it. Over the summer it rebuilt the agent with web data and auto layout, moved Python to a server sandbox with any PyPI package, and added longer agent conversations, a faster empty-canvas start and catalog views that stay populated while they refresh.

What is Marker.io?

Marker.io stops waiting for bug reports and starts scanning sites for accessibility issues.

Marker.io began as a widget for reporting website bugs and spent the past year adding AI to every step: translation, rewriting, title generation and an MCP server that lets coding agents fix issues from a Marker URL. In late October it launched Website Monitoring, which scans chosen pages on a schedule with 90 WCAG 2.2 AA accessibility checks and turns failures into issues.

Count's agent now shows the chain of cells and assumptions behind every answer it gives.

◆ Current state

Count is a data-canvas analytics tool organized around an AI agent. Its late-October release added Reasoning Chains, which link each claim and chart in an agent answer back to the cells, sources and assumptions behind it. Over the summer it rebuilt the agent with web data and auto layout, moved Python to a server sandbox with any PyPI package, and added longer agent conversations, a faster empty-canvas start and catalog views that stay populated while they refresh.

◆ Where it's heading

Count is making the agent the main way to work in the canvas, then adding the checks that let people trust its output. Reasoning Chains and server-side Python with managed secrets point at analysis that can be audited and run on real data. Steady fix lists for agent edits show the agent is still being hardened.

◆ Prediction

Expect more ways to inspect and correct agent work, building on Reasoning Chains. The entries don't show whether chains will extend to Slack answers.

3.8

Marker.io stops waiting for bug reports and starts scanning sites for accessibility issues.

◆ Current state

Marker.io began as a widget for reporting website bugs and spent the past year adding AI to every step: translation, rewriting, title generation and an MCP server that lets coding agents fix issues from a Marker URL. In late October it launched Website Monitoring, which scans chosen pages on a schedule with 90 WCAG 2.2 AA accessibility checks and turns failures into issues.

◆ Where it's heading

The product is moving from collecting problems people report to finding problems on its own, and then handing them to coding agents through MCP. Accessibility is the first monitoring check, and the release title says it is only the start. Workflow statuses and analytics fill in the team side.

◆ Prediction

Expect more monitoring checks beyond accessibility, since the release frames accessibility as the first. How monitoring is priced is not clear from the entries.
