TeraBox

TeraBox costs nothing to start, and the free account comes with up to 1 TB of cloud storage. That is the main draw.

The service is a cloud storage and online file transfer platform that also includes AI writing tools, so your files and your drafts can live in one place.

The AI side covers three jobs: an AI Presentation Maker that builds slide decks, an AI Essay Writer, and Smart Paraphrase for rewording text.

These are aimed at academic work and presentations, which makes TeraBox a reasonable pick for students who already need somewhere to keep documents.

If you only want a dedicated writing assistant, the storage focus may feel like extra baggage, but the free pricing makes it easy to try the AI tools alongside it.
