Keep the PDFs, handouts and recordings from your language course together. Translate words as you read, hear text read aloud, get transcripts of short recordings you upload, and keep one word list for the whole course.

A few weeks into a course

Every lesson comes with more files.

A PDF in one email, a Word document in another, the audio for a listening exercise somewhere in your downloads, and your notes in yet another app. Glotsmith puts all of it in one place.

How it works

Your course does the teaching. Glotsmith is where you study it.

  1. Create a course

    Choose the language you're learning and your own language. Naming the course is optional.

  2. Add files as they arrive

    Upload the PDFs, handouts and recordings you get in each lesson. They all stay together.

  3. Study on the page

    Open a PDF and highlight a word you don't know to translate it, hear it read aloud, or save it to your word list.

Study tools, right where you're reading

No more copying and pasting into a translator in another tab.

Read your PDFs

Pages that already contain text read free on every plan. Scanned pages and photos can be read too, whenever you ask.

Translate and listen

Highlight a word or a sentence to translate it or hear it read aloud. For longer texts, go line by line with the translation next to each line.

Transcripts of recordings

Turn a short recording you upload into text, so you can read what was said and look up the words.

Notes on the page

Draw on a page with a pen or highlighter, add your own notes, and leave notes at the exact moment in a recording.

One word list for the course

Every word you save goes into one list for the whole course, with its meaning. A word links back to the section you saved it from.

Search your course

Find a note, a translation or a word you saved weeks ago, anywhere in your course.

Translating, listening, transcripts and scanning come with a monthly allowance on every plan. Paid plans include more.

Why it exists

I built it for my own Italian course.

I signed up for an online Italian course: one teacher and a group of twenty students. Every lesson, we worked from documents, audio and video files the teacher sent over, and it got very messy. I wanted one organized place for all of it, so I built Glotsmith.

I still make and run it on my own, with no investors and no ads. If you have a question or an idea, email me at mihail@glotsmith.com. I read every message.

Questions, answered

What is Glotsmith?

Glotsmith is one place for everything from your language course. Upload the files you're given and keep them together, then study your PDFs right on the page: translate a word, hear it read aloud, take notes, and build one word list for the whole course.

Who is Glotsmith for?

Adults taking a language course, whether online, at a language school or at university, who get their study material as files. It also works if you're studying from material you already have, like a coursebook you own and its audio. If you're starting from scratch with nothing to read or listen to, an app with built-in lessons will suit you better.

What files can I upload?

PDFs, Word documents, text files, photos (JPG, PNG or WebP), and audio and video. PDFs and photos open in Glotsmith, so you can read them and mark them up. Word and text files are stored with the rest of your course but don't open inside Glotsmith, so if you want to study a Word document on the page, save it as a PDF first.

Is Glotsmith free?

Yes. You can start for free with no credit card. The Free plan lets you read your own PDFs, translate, build a word list, take notes and more, with a monthly allowance for translating, listening, transcripts and scanning. Paid plans include more. See the Pricing page for details.

Is my content private?

Your content is not made public by default. Only you, and anyone you share a link with, can open it, and search engines won't list anything you share unless you choose to publish it. We don't use your content to train AI, and we only send what a feature needs: the text you select to translate or read aloud, the audio you choose to transcribe, and the pages you ask us to read text from. Everything you keep in Glotsmith is stored on servers in the US and sent over encrypted connections. We don't sell your data, and there are no ads. See our Privacy Policy for details.

Can I download or delete my data?

Yes. You can download everything you've made, including your notes, word lists and files, in one go. You can also delete your account from your settings at any time. Our Privacy Policy explains what we keep afterwards and why.
