Claude Overlay Review (2026): Pricing, Features & Honest Verdict

TLDR

Claude Overlay is a free, open-source floating desktop chat that puts Claude Code on top of every window and lets it see your screen. It runs the full agent on your existing Claude subscription, so it edits files and runs commands, not just talks. Best for: Windows developers already paying for Claude. Price: Free (open source), needs a Claude Pro/Max plan. Rating: 7.1/10

What is Claude Overlay?

Claude Overlay is a frameless, always-on-top chat window that floats over everything you do on Windows. You summon it with a hotkey, ask about whatever is currently on screen, and it captures all your monitors before answering. Crucially, it is not a wrapper around a chat API. It spawns the actual Claude Code CLI as a subprocess, which means the same agent that edits files and runs shell commands is now looking at your screen and acting on your desktop, not just returning text.

It launched on Product Hunt on July 14, 2026, where it landed at #7 with 42 upvotes, and it is built and maintained by a solo developer, shengyanlin. The project is open source under the MIT license and, in a nice bit of self-reference, was built with Claude Code itself. This is a third-party community tool, not an official Anthropic product, so there is no company behind it and no support desk. What makes it matter is the workflow shift: instead of alt-tabbing to a terminal or a browser tab, the agent comes to you and can see the document, spreadsheet, or bug you are staring at.

What Are Claude Overlay’s Key Features?

Screen vision on every message

The overlay automatically grabs a screenshot of every connected monitor before each message you send, labelling primary versus secondary displays so Claude knows which screen you mean. You can also paste any image directly with Ctrl+V. This is what lets you say “fix the typo on this slide” or “fill in this cell” without telling it where the file lives or even switching windows.

Full Claude Code agent, no API key

Because it drives the real Claude CLI, it inherits the full agent: it can edit files, run commands, and reach into the app on your screen. It runs entirely on your own Claude Pro or Max subscription with no separate API key and no metered per-token billing, which is a genuine cost advantage over tools that bill through the API.

Collapsible floating orb and multi-overlay support

When idle, the window collapses to a small draggable orb that stays out of your way, then expands on demand. You can run multiple overlays at once and name each one for a different task, so a debugging session and a document-editing session do not share the same context.

Live streaming, model switching and a read-only mode

Responses stream token by token with tool-call chips so you can watch what the agent is doing. There is an in-app model selector with a context-usage meter, Ctrl +/- text zoom, and an optional “plan” (read-only) mode that restricts Claude to viewing without changing anything, which you will want given the defaults.

How Much Does Claude Overlay Cost?

Claude Overlay itself is completely free. It is open source under the MIT license, so there is no license fee, no subscription for the overlay, and no per-token charge from the tool. The only real cost is the Claude subscription it runs on: a Claude Pro plan at $20/mo or Claude Max at $100-200/mo, which most people in the target audience already pay for. Compared to a commercial screen-aware assistant like Cluely, which charges around $20/mo on top of its own model costs, Claude Overlay adds nothing to your bill because it reuses the subscription you already have. You do need Python 3.10+ and the Claude Code CLI installed and on your PATH, but those are free too.

Who Is Claude Overlay Best For?

This is a tool for people who already live in Claude Code and want its agent available everywhere on a Windows machine, not just in a terminal.

• Use Claude Overlay if you are a Windows developer or power user with a Claude Pro/Max subscription, you are comfortable installing a CLI and running Python, and you want an agent that can see and act on any app on your screen for free.
• Skip Claude Overlay if you are on macOS or Linux (it is Windows 10/11 only for now), you do not have a Claude subscription, or you want a polished, supported commercial product with a company behind it and safe defaults out of the box.

Best Claude Overlay Alternatives

Screen-aware desktop AI assistants are a crowded space in 2026. If Claude Overlay’s Windows-only, bring-your-own-CLI approach does not fit, these are the closest options.

Cluely

Cluely is a commercial always-on-top assistant that sees your screen and listens to meetings, with a real company, cross-platform builds, and support. It starts around $20/mo on top of its own AI costs, so it is more polished but not free the way Claude Overlay is.

Cursor

Cursor is an AI-native code editor rather than a floating overlay, but for the developer use case it covers a lot of the same ground with a far more integrated agent experience. It runs $20/mo for Pro and works on Windows, Mac and Linux, though it lives inside the editor rather than over your whole desktop.

ClaudeBar

ClaudeBar is a macOS menu-bar companion for Claude Code that tracks usage quotas rather than acting as a full agent overlay. It is free and open source, and it is the closest thing to a native-Mac Claude companion while Claude Overlay remains Windows-only.

Final Verdict: Is Claude Overlay Worth It?

For the right person, Claude Overlay is a genuinely clever piece of free software. Getting the full Claude Code agent floating over every window, seeing your screen, and acting on your files with no extra cost beyond a subscription you already pay for is the kind of workflow upgrade that feels obvious once you have it. The multi-overlay support and read-only plan mode show real thought, and being MIT-licensed means you can inspect and modify everything.

The caveats are real, though. It is Windows-only, it requires installing a CLI and Python, there is no company or support behind it, and the default “bypassPermissions” mode lets the agent edit files and run commands with no confirmation, which is a serious footgun if you do not switch on read-only mode first. If you are a Windows developer with a Claude subscription who is comfortable with those trade-offs, install it today. If you want something polished, cross-platform, and safe by default, wait or pick a commercial alternative.
