Maho vs Chrome with Gemini: agentic-first vs AI-bolted-on
Google ships Gemini inside Chrome. Maho ships an agentic side panel with BYOK. Two AIs, two invocation models, two views of what is happening on your screen.

Tool calling is not a feature. It is a contract. This is the long version of how we honor that contract inside Maho’s side panel.
An agentic browser that does not ask is not safe. An agentic browser that asks too much is not usable. The middle is engineering work, not a slogan.
Dia and Maho are both agentic browsers shipped in 2026. They make different bets about where context lives, who owns the model, and what the browser is allowed to do on your behalf.
MCP gave language models a way to call tools. The browser is the right host for the result. This post is the long version of that claim.
Both browsers are Chromium forks. Both target AI-assisted workflows. They disagree on almost everything else: how AI should be priced, how many devices it should run on, and how much autonomy an agent should have.
Arc reached for a browser that worked the way power users actually browse. The Browser Company moved on before that idea was finished. Maho picks up the parts that mattered.
Every browser now has a chat panel. Some of them can take action. The difference matters more than the marketing copy admits.
Agentic browsers fail in four shapes. The shapes are old. The defenses are not magic. Here is what each looks like in the wild and how the Maho host responds.
Every agentic browser has three modes hiding inside it: chat, act, and refuse. The bug is when the user cannot tell which mode the assistant is in. Here is how Maho makes that visible.
Most agentic browser demos stop at the summary. The interesting work starts after the summary, when the agent has to do something with what it just read.
Opera ships Aria as a bundled, hosted AI sidebar. Maho ships an agentic panel with BYOK. The comparison is less about features than about defaults.
Safari is good. Safari is the default. Those two facts are the entire reason most Mac users never try anything else. This post is for the rest.
Maho’s AI panel has two scopes: the page in front of you, and the conversation you have been having. They are not flavors. They are different inputs with different failure modes.
Most browsers put the assistant somewhere convenient and call it done. The placement choice is doing more work than it looks. Here is the reasoning.
Prompt history is the kind of data that should live where you can read it, back it up, and grep it. SQLite was the dull, correct answer.
Every browser now has an AI sidebar. But which ones can actually do things? We compare Maho’s agentic AI panel against Dia, Chrome + Gemini, Edge + Copilot, Brave Leo, Opera Aria, and SigmaOS.
