Comparison
Echo vs Claude on a Mac.
Claude’s desktop app can be summoned from anywhere on your Mac. So can Echo. What happens next is where they stop resembling each other.
· Written by the people who make Echo
The short version
Claude is an assistant you talk to: its Mac app has quick entry — double-tap Option by default — which opens a box from any app and starts a new conversation. Echo has no conversation. You select text where it already lives, press one shortcut, and the translated, cleaned-up or summarised version replaces it in place. Claude is where you think something through; Echo is where you fix the sentence in front of you without going anywhere.
What Claude’s Mac app gives you
Claude’s desktop app is a serious piece of work: long context, files, projects, and an interface that stays out of the way. Quick entry makes it fast to reach — double-tap Option (or set your own shortcut) and a small box appears over whatever you are doing, ready for a message. It is available on the free plan as well as the paid ones.
What that box does is start a conversation. You type, Claude answers in its own window, and the result is yours to read, refine and — when you want it somewhere else — copy. That is exactly right for the work Claude is best at: reasoning about something long, drafting from a blank page, going back and forth until the thing is good.
It is a poor fit for the twenty-second job. Fixing the tone of a Slack message you have already written should not involve starting a conversation about it.
What Echo does instead
Echo begins where Claude ends: with text that already exists. Highlight it anywhere on your Mac — Mail, Safari, Slack, Notes, a PDF, a code editor — press ⌘1, and a popup opens on top of the app you are in. Five tools sit one keystroke away: Translate, Reply, Clean Up, Summarize, Write as Email. Pick one and the result is written back over your selection, or copied if you prefer to place it yourself.
Nothing about that flow involves a window you have to come back from. There is no prompt to compose, no thread to name, no answer to copy. Echo reads your selection through macOS Accessibility, so it is not a list of supported apps — it is anywhere text can be highlighted.
The trade is obvious and deliberate: Echo cannot discuss anything with you. Ask it something open-ended and you are using the wrong tool. That constraint is what lets the whole interaction fit in about two seconds.
Side by side
What the shortcut opens
Echo: A popup over your current app, acting on the text you selected.
Claude desktop: A quick-entry box that starts a new Claude conversation.
Where the result lands
Echo: Over your selection, in place — or on the clipboard if you choose.
Claude desktop: In the Claude window, for you to read and copy.
What you have to write
Echo: Nothing. Pick one of five tools, or type an instruction if you want one.
Claude desktop: A message — the prompt is how you get anything at all.
Best at
Echo: Fast, repeated edits to text you already have.
Claude desktop: Long documents, reasoning, projects, code, anything open-ended.
Reach into other apps
Echo: Reads and replaces the selection in any app, via macOS Accessibility.
Claude desktop: Lives in its own window; moving text in and out is copy-paste.
Your text afterwards
Echo: Nothing kept or logged on our servers. A local history stays on your Mac, yours to delete or expire.
Claude desktop: Conversations are stored in your Claude account until you delete them.
Price at the time of writing
Echo: 7-day free trial, then $9.99 / month or $79 / year.
Claude desktop: Free tier available; Claude Pro is $20 / month, less annually.
Platform
Echo: macOS 13 or later, native Swift, Apple Silicon and Intel.
Claude desktop: macOS, Windows, web, mobile.
They are not really competitors
It is tempting to line these up as rivals because both answer a keyboard shortcut. But one is a place you go to think, and the other is a thing that happens to the sentence you are looking at. The honest recommendation is that if you already pay for Claude and it is doing the job, keep it — and notice how often you use it for something that took ten seconds of thought and a minute of copying.
That gap is the whole reason Echo exists. Not the hard questions, which deserve a real assistant, but the small ones you would rather not leave the app for.
Which one, when
Reach for Claude when
- The work is long: a document, a report, a codebase, a decision.
- You want to go back and forth until the answer is right.
- You are starting from nothing rather than editing something.
- You need files, projects, or context that spans a whole session.
- You work on Windows or the web as much as on a Mac.
Reach for Echo when
- The text exists and the job is obvious: translate it, tidy it, shorten it, answer it.
- You are mid-sentence in another app and do not want to leave it.
- You do it many times a day and the copying is what actually costs you.
- You want the result written back in place, not handed to you in a window.
- You would rather nothing was stored anywhere afterwards.
Questions
Only for one part of what Claude does. Claude is a full assistant — long documents, reasoning, projects, code. Echo does five fixed jobs on text you have already selected, inside the app you selected it in. If you use Claude to think, Echo does not replace it. If you use Claude mostly to rewrite short passages, Echo does that without the trip to a chat window.
Not at the time of writing. Claude’s quick entry — a double-tap of the Option key by default, and configurable — opens a box from anywhere and starts a new conversation with what you type. It is a fast way into Claude, not a way for Claude to reach into your email and change a paragraph. Echo works the other way round: it never opens a conversation, it changes the selection in place.
Claude, comfortably. It handles long context, files and multi-step work that Echo is not built for. Echo is deliberately small: a selection, a tool, a result, in about two seconds.
At the time of writing, Claude has a free tier and Claude Pro is $20 a month, less on annual billing. Echo is $9.99 a month or $79 a year after a 7-day free trial. Plenty of people pay for both, because they are not doing the same job.
Echo sends your selection to a large language model through Echo’s own backend, and the API key never ships inside the app. Which model provider sits behind that is something we tune for quality and speed; from your side it is one subscription and one shortcut.
No — there are no conversations to keep, and nothing is stored or logged on our servers. On your Mac, Echo keeps a local history so you can look back at what you did — it is never synced or uploaded, you can delete any entry, and you can have it drop the text automatically after a while.
Echo is free to try for 7 days. Download it for macOS.
