Letterin vs Resume.io: which one fits you?

What Resume.io does well

Resume.io's editor is simple and fast, its templates are clean, and you can make a CV and a cover letter in the same look. It runs local sites for several countries. For someone who wants a tidy resume with little effort, it is a comfortable tool.

Pricing: the trial and the 4-week renewal

In October 2026 Resume.io's pricing page limited the free plan to one resume and one cover letter, downloadable as TXT only. A PDF needs the 7-day trial at $2.95; if you do not cancel, the plan renews at $29.95 every 4 weeks. A 4-week cycle bills 13 times a year, so that is a little over $30 a month. The quarterly plan is $49.95.

Letterin has no trial and no subscription that starts on its own. A free account opens as many CVs as you like and downloads PDF and DOCX files with no watermark. Only AI usage is paid: about three tailoring runs a month on the free plan, Pro at $7.99 a month or $17.99 for three months.

Tailoring: one resume, or one per posting

On Resume.io you write the resume yourself and get AI help with sentences. A version for each posting means copying the resume and changing it by hand.

Letterin is built for that loop. Your master CV is kept once; paste a posting or give its link and it gets its own copy, with the match score and the missing terms, and the AI proposes a rewrite of your summary, bullets and skills for it. You approve each suggestion section by section, and nothing that is not on your CV is added. It writes the cover letter for the same posting from the facts on your CV, and the application goes on a tracking board.

Language: one interface, another CV language

Letterin works in English, German, French, Spanish, Portuguese and Turkish, and the interface language and the CV language are chosen separately, so you can run the app in English and write a German CV. Every AI suggestion is written in the CV's language, and that is checked, not hoped for.

Which one to pick

If you want one tidy resume, quickly, and a short subscription is fine, Resume.io does the job; note when the trial ends.

If you apply a lot and want a CV written for each posting, apply in more than one language, or do not want to pay a subscription just to download, Letterin fits better.
