Add study material

atode works best when you add the material your tutor actually used.

Supported sources

• Pasted text in the Add lesson form.
• Local PDF, TXT, JPG, JPEG, PNG, GIF, or WebP files up to 20 MB.
• A public HTML or text URL.
• A YouTube transcript URL when a transcript is available.

Choose pasted text for a quick excerpt, a local file for a handout, and a public URL when the lesson is already online. A source is processed for your account; it is not published by adding it.

Sources that will not work

Remote PDFs, sign-in pages, paywalls, and JavaScript-only pages cannot be retrieved reliably. Download a file you are allowed to use and add it locally, or paste the relevant text instead. A YouTube video without an available transcript needs a pasted note.
