Build with agents

The agent works on the same files you do, on your own device. It reads your real project, proposes edits, and waits for your review. You use your own key, at the provider's price.

One place to rule them all

Built in tools and skills

We have built extensive tooling that enables agents to efficiently create, edit and review your site.

Staged, reviewable diffs

Users will visually see what's changed, and decide to keep it or not

Bring your own key

We don't want to be a middleman, bring your own key for Anthropic, OpenAI and OpenRouter.

Chat lives with the site

Chat history stored with the site, building on the context of the AI.

AI without a workflow becomes chaos

AI without a workflow becomes chaos

Prompting a coding tool can ship a first page. Ongoing marketing work needs review, constraints, and a place where changes become publishable history.

The agent should see the same files you ship

Guessing from a pasted snippet creates drift. Grounded edits on the live project keep the site coherent.

You should not pay rent on someone else's model meter

Hosted builders resell AI as credits. By Framer's own figures, a generated landing page costs about 300 credits of a 1,000-credit Basic month, and unused credits do not roll over. Splitleaf does not insert itself as a middleman tax on every token. You bring the key. You pay the provider. The agent stays a feature, not a new subscription layer.

Safe by construction

Project-scoped assistant

The agent works on the currently open site. File access stays sandboxed to that site root.

Safe by construction

Edits are staged with baselines. Writes use precise replacements. Nothing is committed to Git by the agent. You review before publish.

BYOK

Connect your model API key in site settings. Keys are stored for that site's agent connection. Splitleaf is not the LLM bill.

Local-first chat trail

Sessions and staging live under .opt-one/agent/ in the site. Usage can follow the site across devices. The conversation stays near the work.

Common questions

Does the agent publish for me?
No. It stages edits. Publish stays a deliberate step with a change review.
Do I need to be technical to use it?
No. The agent is built for non-technical users working on a real site, with reviewable results instead of raw repo commands.
Is agent usage included in the license?
The desktop license covers the app. Model usage is billed by your provider through your key.
Why not just use Cursor or Claude Code?
Keep them. They are excellent at creating a site. Splitleaf is where the site lives afterwards. It gives you a visual canvas, a CMS and a publish board, all on the same files. People who do not code can review, edit and publish. The built-in agent stages every change for you to keep or undo.
Is the AI local today?
Not yet. The agent calls the provider you connect, on your own key. The app, your files and your edits are already on your machine, and no server of ours sits between you and the model. Local models are the next step, and the architecture is built for them.
