aiCat vs DeepL
DeepL: free tier with a character cap; Pro starts from about $9/month. aiCat: free to start, Premium starts from $6/month. Neither is a superset of the other, and this page says which is which.
DeepL is not a weaker version of anything — between European languages it is frequently the best translation you can buy, and a translator who is paid by the word notices the difference. The question this page is actually about is narrower: whether translation is a job you do, or something that happens forty times a day in the middle of doing something else.
What follows is written to be usable by somebody who ends up choosing DeepL. Prices are floors — the cheapest tier each product is honestly available at — checked in August 2026 and worth re-checking on the vendor's own page before you decide on price alone.
Where the two differ, and where they do not
| aiCat | DeepL | |
|---|---|---|
| What it is built to do | Whatever the selected text needs — translate it, but also explain, proof-check, rewrite or answer questions about it | Translate text and documents as well as it can be done |
| Raw quality, European pairs | Very good; an LLM reading the surrounding context | Frequently the best available, and the benchmark others quote |
| Language coverage | Whatever the underlying model speaks, which is far wider outside Europe | Around 35 languages, with the depth concentrated in Europe |
| Glossaries and formality | Asked in words, not stored as a rule | Stored glossaries and an explicit formal/informal switch |
| Whole documents | No — it works on a selection | Yes, with the layout preserved |
| Mixed-language text | Handled: one selection can hold three scripts and come out right | Assumes a single source language per request |
| Learning aids | Up to ten keywords with translations and transcriptions | None |
| Price floor | Free; Premium starts from $6/month and covers every other task too | Free tier with a character cap; Pro starts from about $9/month |
What aiCat adds around the translation
- Translation is one of several things the same key does, so there is no second subscription for the other five
- Any language the model speaks, including scripts DeepL does not cover, and text that changes language mid-sentence
- Up to ten keywords with transcriptions, so reading in a second language gets easier rather than staying the same
- Starts free; Premium starts from $6/month
What DeepL is simply better at
- Often the best raw translation between European language pairs, and the difference is audible to a native reader
- Glossaries: your product names come out the same way every time
- Formality control as a switch rather than a request
- Whole files — a PDF or a .docx goes in and comes out translated
Choosing between them by the text in front of you
You translate documents for clients
DeepL. Files, glossaries and formality control are the job, and aiCat does none of the three.
You read foreign-language messages all day
aiCat. The cost there is the round trip, not the translation.
Your languages include Hebrew, Arabic, Thai or Hindi
aiCat. This is where DeepL's coverage thins out and a frontier model's does not.
One message contains two languages
aiCat. DeepL expects a single source language per request.
You are learning the language you are reading
aiCat. The keyword lists with transcriptions exist for exactly that.
Consistency of terminology matters more than anything
DeepL. A stored glossary beats a well-phrased request every time.
Hands-on: the same week of foreign-language reading
One person's account of using both. It is an opinion, it is not a benchmark, and it is here because the rest of this page is a table.
A week of reading German and Hebrew support threads made the difference concrete. On the German, DeepL's output was better often enough to notice — smoother, and it never fumbled a separable verb the way the LLM occasionally did. On the Hebrew it was not close, and on the three threads that switched between Hebrew and English mid-paragraph DeepL had nothing sensible to do at all. What ended up mattering more than either was the round trip: with DeepL open in its own window, I translated the messages I could not guess at; with a hotkey, I translated all of them, including the ones I would have skimmed and misread.
Stay on DeepL for professional European translation
If you translate professionally between European languages, or you send whole documents through, DeepL is the better tool and the glossary feature alone is hard to give up: product names, legal terms and job titles coming out the same way every time is not something you can ask an LLM for and rely on.
aiCat is for the other pattern — reading in a second language all day, in a dozen applications, where the cost is not translation quality but the fifteen seconds it takes to get the text into a translator and back.

Frequently asked
Is aiCat a good DeepL alternative?
It depends on why you are looking. aiCat replaces DeepL for people who want one key that acts on text anywhere on the machine, in any language. It does not replace DeepL for translation quality between european languages that is still the reference point for everyone else, which is what DeepL is built around.
Is aiCat cheaper than DeepL?
aiCat's floor is lower, but the comparison is only fair if you count what each price covers. DeepL Pro starts from about $9 a month for translation. aiCat Premium starts from $6 and the same coins pay for proof-reading, explanation, AI detection, dictation and read-aloud — and can be bought outright instead of subscribed to, which is the right shape if you translate something twice a week. If translation is most of your work, DeepL's quality is worth more than the three dollars.
Can I use aiCat and DeepL together?
Yes, and it is a common setup. DeepL for the documents and the European pairs where its quality shows; aiCat for the in-place reading — a message, a code comment, a support thread — and for the languages DeepL does not cover.
What does DeepL do that aiCat does not?
Often the best raw translation between European language pairs, and the difference is audible to a native reader; Glossaries: your product names come out the same way every time; Formality control as a switch rather than a request; Whole files — a PDF or a .docx goes in and comes out translated.
What is aiCat?
aiCat is a desktop app for macOS, Windows and Linux. You select text anywhere on your computer, press one hotkey, and an AI does what you need with it — proof-read, translate, explain, check the facts, read it aloud, or answer a question about it.
Does aiCat work in every application?
Yes. It works at the operating-system level rather than through per-app plugins, so it covers native apps, browsers, IDEs, terminals and PDF viewers alike.
