For everyday users who just need quick, affordable translations of documents or text, Polygloss is the simpler choice despite its limited free plan and lack of mobile app. Smartling is a powerful but expensive platform built for teams managing large-scale localization projects, not for casual use. The single biggest difference: Polygloss is a lightweight translation tool, while Smartling is a full-blown translation management system with a steep learning curve and high cost.

Common questions
Yes, for a single document Polygloss is better because it's simpler, cheaper, and you can upload and translate in minutes. Smartling would require you to set up a project, define workflows, and pay more for a single use.
Neither tool has a mobile app, so you cannot use them on your phone. Both require a computer with internet access.
Polygloss is more affordable for a freelancer. Smartling's pricing is high and designed for teams, so it's not cost-effective for an individual.
Yes, Smartling supports code, JSON, XML, and other developer-friendly formats. Polygloss does not support code — it's limited to documents like DOCX and XLSX.
Polygloss is much easier — you just upload a file and get a translation. Smartling has a steep learning curve for its advanced features, though basic translation is still manageable.
Polygloss has a free plan with limited language support. Smartling offers a free tier as well, but it's likely limited in features. Both let you test before paying.
Polygloss wins for everyday users needing quick, cheap translations; Smartling is for businesses with complex localization needs and a bigger budget.
If you're an everyday person who just needs to translate a document or two without fuss, go with Polygloss — it's simple, affordable, and gets the job done. If you run a business with a team that needs to localize an entire website or app with professional review, Smartling is the right tool, but be ready for the cost and learning curve.
