Agent harness V2
Today we launch agent harness V2. The agent behind Splitleaf is now faster and cheaper to run, and it can do more. Give it a whole website to clone, a product update to change across all blog posts or an SEO task. It works until the job is done.
A quarter of the tokens
Each step now sends about a quarter of what it used to. Most of that comes from the provider's cache. You get the same work for less money, and answers arrive faster.
Longer jobs
Ask for a full redesign, ten new pages or a site-wide fix. The agent keeps going until it is finished.
When a chat gets long, it summarises what it has done and carries on. You see a Summarising step, then the work continues.
Even better SEO agent
Ask for a SEO audit and let the agent do all changes needed. It now has all the tools to perform and test all changes. Change URL's with forwards, check internal links in huge projects, change robots.txt or llms.txt, set the favicon, append fonts instead of CDN.
Each change shows in the chat. You keep or discard it, as usual.

Updated table designer

You now edit a table in a content item on the table itself.
Move the pointer to the edge of a row or column to see its grip. Drag the grip to move it, or select it to open a menu.
Use the bars on the right and below the table to add columns and rows. Right-click a cell for more actions.
Align each column left, centre or right, and your site shows it.
