Guide
Echo for students, on a Mac.
Forty pages of reading before Thursday, a source in a language you half-speak, and an email to a professor you have rewritten four times. None of that needs a chat window.

The short version
A study day is mostly reading things that are too long and writing things that are too careful. Echo sits over whatever app you are in: select a passage and it summarises it, translate a source without leaving the PDF, tidy the paragraph you already wrote so it says what you meant, and get the email to your professor sent instead of rewritten. What it will not do is write your essay — there is no blank page in Echo, and that is on purpose.
A study day, with Echo
Six moments where the tab-switching normally happens. Every one of them is a selection, a shortcut and about two seconds.
The 40-page PDF before a seminar
Select a section, press your shortcut, Summarize. You get the argument in a few lines and can decide which parts genuinely need reading closely.
A source in another language
Select the paragraph in the PDF and translate it in place — no copying into a translator tab and losing your position in a 300-page document.
The email to a professor
Write it badly and quickly, select it, Clean Up. The tone lands where you wanted it on the first try instead of the fourth rewrite.
Lecture notes into something readable
Half-sentences typed during a lecture become a paragraph you will still understand in six weeks, in the notes app you already use.
A group chat in a language you are still learning
Follow the thread without a translator app open beside it, and answer in the same window.
Applications and internships
A cover letter you wrote yourself, cleaned up so a rushed sentence does not cost you the interview.
Why not just use a chatbot
You can do all of this in a chat window, and plenty of people do. The cost is the trip: copy the paragraph, find the tab, paste, explain what you want, wait, read, copy the answer, find your document again, paste. It is thirty seconds each time and it takes your attention out of the thing you were doing — which, when the thing you were doing was concentrating on a hard reading, is the expensive part.
Echo removes the trip rather than the work. The popup opens on top of the PDF, the email, the notes app, and closes when it is done. You never leave the page you were on, so you never have to find your place again.
About writing your own work
Worth being blunt, because it is the question everyone actually has. Echo is built to help you read faster and to finish writing that is already yours. Clean Up fixes grammar, spelling and clumsy phrasing while keeping your voice; it does not invent arguments, and it cannot do your thinking for you.
It also has no idea what your university allows, and we are not going to pretend otherwise. Academic integrity rules vary a lot, they are changing quickly, and they are the ones that count — go and read yours. Fixing the grammar of a paragraph you wrote sits in a very different place from submitting work you did not write, in almost every policy we have seen.
If what you want is something that produces an essay you can hand in, Echo is genuinely the wrong tool, and we would rather say so on this page than have you find out after paying for it.
The three you will use most
Summarize
Long readings, dense chapters, threads — condensed to the point, in the app you are reading them in.
How it worksTranslate
Sources, messages and papers in another language, translated where they sit.
How it worksClean Up
Your own writing, fixed for grammar and phrasing without losing the way you write.
How it worksQuestions
No, and it is not built to. Echo works on text you have already selected — it will tidy a paragraph you wrote, translate a source, or condense a reading. There is no “write me 2,000 words on the French Revolution” in it, because there is no blank page and no conversation. If that is what you are after, this is the wrong tool.
That depends on your institution, and its rules are the ones that count — read them. As a rough guide, most policies treat fixing your own grammar and phrasing very differently from submitting text you did not write. Echo is designed for the first: understanding sources faster, and finishing writing that is already yours.
Yes, as long as the text can be selected. Echo reads your selection, so a normal PDF, a slide deck or a web page all behave the same way. The one case that will not work is a scanned page with no text layer — there is nothing to select.
Yes. Select the passage, use Translate for the language you want, or type your own instruction — “summarise this in French, in five bullet points” — and Echo follows it. Reading in a second language and thinking in your first is exactly the case it handles well.
Not today. Echo is $9.99 a month or $79 a year, with a 7-day free trial that needs no card. If a student plan appears, it will be on the pricing page — we would rather say no now than imply something that does not exist.
Not by us. Your selection goes over HTTPS to Echo’s own backend, which produces the result and then keeps neither the text nor a log of it. 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, no card. Download it for macOS.
