Common questions

Can I use Polyglot AI or Smartcat on my phone?

No, neither tool has a mobile app. You can only use them on a computer through a web browser.

Which is better for translating a website: Polyglot AI or Smartcat?

Smartcat is better because it can sync with your website and manage ongoing updates. Polyglot AI can translate a webpage you paste in, but it won't handle the full site.

Is Smartcat worth the $1,200/year for a freelancer?

Only if you translate large volumes regularly and need human review features. For occasional work, Polyglot AI or free tools like Google Translate are more cost-effective.

Does Polyglot AI have a free version?

The pricing is not clearly published, so it's unclear if a free tier exists. You may need to contact their sales team.

Which tool is easier to learn for a beginner?

Polyglot AI is simpler — just paste text and get a translation. Smartcat has a steeper learning curve because of its project management features.

Can I use these tools for translating legal or medical documents?

Both tools recommend human review for critical content. Smartcat makes that easier by including human review in its workflow. Polyglot AI is AI-only, so you'd need to arrange review separately.

Polyglot AI wins on simplicity and price, Smartcat wins on power and workflow — choose based on whether you need a quick translation or a full localization system.

If you just need to translate a few things now and then, start with Polyglot AI — it's simpler and likely cheaper. But if you're running a business or regularly handling translations that need to be polished and reviewed, invest in Smartcat despite the cost and learning curve. Neither works on your phone, so plan to use a computer.
