A freelance translator’s income is words per day times rate, and AI has put pressure on both sides of that equation. Clients expect faster turnaround, some expect machine-translation post-editing rates, and agencies still ask for files in the format their CAT tool produces.
This guide is for the translator’s side of the desk: the computer-assisted translation (CAT) tools and machine translation (MT) engines you work in every day. If you are a business owner who wants to translate your own website or product pages, our guide to AI translation tools for solopreneurs covers that instead. Pricing below comes from vendor listings and third-party trackers, so confirm on each site before buying.
The best tools for freelance translators
Trados Studio: the agency standard
Trados Studio is the CAT tool many agencies expect you to own, and its file formats show up in a lot of job postings. Capterra lists a Freelance Subscription at $408 per year and one-time Freelance and Freelance Plus licenses at $915 and $1,110. All listed plans include machine translation, terminology, and review features, and recent releases add AI-assisted suggestions.
Best for: translators who get most of their work from agencies that specify Trados. Watch out for: it has a steep learning curve and is Windows-only.
memoQ translator pro: the strongest alternative
memoQ translator pro is the main rival to Trados, praised for translation memory and termbase handling and its LiveDocs reference corpus. A pricing tracker verified in October 2026 lists it at $54 per month billed monthly or $436 per year, with a 14-day free trial.
Best for: translators who want a full desktop CAT tool on a subscription without Trados’s price.
Smartcat: free, cloud-based, with a marketplace
Smartcat runs in the browser and has a free plan with built-in AI translation, translation memory, and glossaries. It also runs a marketplace where companies hire linguists and pay through the platform. Paid tiers are aimed at companies rather than individual translators.
Best for: new translators building a client base, or anyone who works on several machines. Watch out for: there is no offline client, and it lacks some advanced editor features found in Trados and memoQ. Check the marketplace’s payout terms directly with Smartcat.
DeepL Pro: the MT engine you plug into your CAT tool
DeepL Pro is not a CAT tool, but many translators run it inside one. Its listing shows Starter at €8.99 per month (€5.99 billed annually), Advanced at €29.99 (€19.99), and Ultimate at €59.99 (€39.99). It integrates with Trados Studio and memoQ, and DeepL says Pro texts are deleted after translation rather than stored.
Best for: translators who post-edit MT output and want a higher-quality first draft for European languages.
OmegaT: free and open source
OmegaT is a free, open-source desktop CAT tool that runs on Windows, Mac, and Linux. It supports translation memory, glossaries, and MT plugins, and it costs nothing to try.
Best for: translators starting out, Linux users, or anyone who wants a second CAT tool without another subscription.
Confidentiality comes first
Before you paste client text into any MT engine or general AI chatbot, check your NDA and the client’s instructions. Some clients forbid MT entirely, and consumer AI tools may retain inputs. A Pro-tier MT service with clear data terms, used inside your CAT tool, is easier to defend than pasting text into a free web page.
Which one should you choose?
- Mostly agency work: Trados Studio, since compatibility matters more than price.
- Want a full desktop CAT tool for less: memoQ translator pro.
- Just starting out: Smartcat or OmegaT, then upgrade when clients ask for a specific format.
- Doing MT post-editing: add DeepL Pro to whichever CAT tool you use.
Translators who also handle video work can expand into subtitling and dubbing. Our guide to AI video dubbing tools shows what clients are using on that side.
A short newsletter for past clients and agency contacts is one of the easiest ways to stay booked. Beehiiv and Kit both make that simple to set up. Beehiiv also powers The Solo Stack, our weekly roundup of tools for one-person businesses.
Frequently asked questions
Do I need Trados to get agency work?
Not always, since memoQ and other tools can handle many Trados file formats. But some agencies require it, so check the job requirements.
Is there a good free CAT tool?
Yes. OmegaT is free and open source, and Smartcat has a free cloud plan.
Is DeepL a CAT tool?
No. DeepL is a machine translation engine. Most translators use DeepL Pro as a plugin inside a CAT tool.
Can I use ChatGPT or Claude for translation work?
They are useful for terminology research and style checks. Only paste client text if your agreement allows it and you understand the provider’s data terms.
Should I buy a perpetual license or subscribe?
Subscriptions cost less up front and keep you on the latest version. Perpetual licenses can be cheaper over several years if you do not need every upgrade.
