Customise Any Site for Yourself or for Your AI Agent. Customaise.
Custom programmable tools
for every open tab.
For you, or for your AI.
Your AI writes the tool. Customaise runs it. No API keys. No OAuth. No headless. No vendor browser. Just the Chrome you're already in.
Add to Chrome
One extension. Two paths.
Unlimited solutions.
Same install. Same consent model. Two completely different jobs.
Reshape any page
Describe the change in plain language. Customaise writes a reversible tweak under the hood, applies it to the live page, and brings it back every time you return. Toggle it off any time.
Create any tool
Create the tools your AI agent can call on the page. Read a dashboard, archive an inbox, submit a form. Every call runs in your signed-in session, gated by your rule: allow, prompt, or deny. You have the final word.
Your web. Not the web.
Every fix you describe becomes a UserScript in your personal library. Running on your sites. Following you across devices. Yours to keep, export, or share.
Inbox that dims promotions. Feed that kills the sidebar. CRM that sorts itself. The web, rewritten one script at a time.
Customaise MCPCustomaise3 toolsStop your agent from guessing.
Your agent can already click through sites, slowly, by reading screenshots. AgentScripts turn that into a sure thing. Describe any action once. Customaise exposes a named tool any agent can call in milliseconds. Every site you use. Under your own session.
Archive the inbox. Place the trade. Export the lead. Book the flight. Your agent, fluent in your sites.
What will you build?
Some start with the fix that's been bothering them for years. Others hand their agent the task they keep doing by hand. Both count.
Cleaner tables.
Filter, sort, hide, dim. Columns that finally behave the way you wanted.
Shortcuts they skipped.
Keyboard controls the tool's designers left out. Back in your muscle memory.
A menu they never shipped.
A floating palette on any page. Every script you install adds an entry. One click, any automation.
Decide, per item.
Agent reads every row, picks the right tool for each. Archive, flag, reply, escalate. Not 'archive fifty'. Fifty judgments in one ask.
Nuance in, tool out.
Agent reads the signal, sizes the risk, fires a bounded order with exact args. Thinking ends in a precise call, not a guess.
Whole workflows, one ask.
Read the lead. Update the CRM. Book the call. Post to Slack. One intent chains through every tool in the right order.
Ready when
you are.
Describe what you want changed, or what you want your agent to do. Customaise runs the rest.
