TeraBox is a cloud storage and file-backup app that gives every signup 1TB of free space, growing past 400 million users by January 2025. Its built-in AI toolkit handles transcription, presentation generation, and document scanning at no extra cost, syncing across web, Windows, macOS, iOS, and Android.
About TeraBox
Flextech Inc., a company headquartered in Tokyo, built TeraBox as a cloud storage and file-backup app in 2020. Its free-storage hook, combined with a built-in AI layer that goes well beyond typical storage apps, is the main reason it grew into one of the more widely used consumer cloud tools. The free plan is aimed at individual users who want a big storage cushion for photos, videos, and backups, such as students and casual creators, rather than teams that need audited compliance: TeraBox has not published a SOC 2 report and has no formal trust center. Privacy-focused users should also note there is no zero-knowledge or client-side encryption, and the company offers no official public API, leaving only unofficial, community-built tools on GitHub for developers who want to integrate with it.
Pricing
Free plan includes 1TB of storage with ads and a 4GB per-file upload cap. Premium starts around 2.99 USD/month for 2TB with faster downloads and no ads; a Premium+ tier runs around 3.33 USD/month in some regions. Separate regional storage add-on packs are priced near 19.99 USD/year. Exact pricing varies by country.
Key Features
- 1TB Free Cloud Storage: Every new account gets 1TB of free storage on signup, far above the 15GB Google Drive or 2GB Dropbox free allowance.
- AI Transcribe: Converts recorded or live audio and video into text with automatic subtitles and an AI-generated summary of key points.
- AI Presentation Maker: Generates a formatted slide deck from a single text prompt with one click, without needing a separate design tool.
- Document Scan & OCR: Scans multiple physical documents into a single searchable PDF with automatic text recognition for editing and organizing.
- AI Writing Tools: Bundles an essay writer and a paraphraser for drafting and rewriting text directly inside the storage app.
- AI Image Generator: Turns a text prompt into an image using named art styles such as Snoopy, Miyazaki, and Cyberpunk, without leaving the app.
- Cross-Platform Sync: Automatically syncs files across web, Windows, macOS, iOS, and Android so files stay reachable from any device.
Pros
- 1TB of genuinely free storage on signup, more than 66x Dropbox's 2GB free tier and 65x Google Drive's 15GB.
- Premium removes ads and doubles storage without the enterprise-style upsells common among mainstream cloud storage apps.
- The built-in AI toolkit (transcription, slide generation, OCR, and writing tools) would cost extra as separate subscriptions elsewhere, but ships free with every account.
Cons
- Free tier shows frequent full-screen ads that reviewers describe as disruptive to the app experience.
- Free plan caps individual file uploads at 4GB, a hard limit for video creators working with larger files.
- No zero-knowledge or client-side encryption, so file privacy depends on trusting Flextech's internal policies rather than technical guarantees.
- Deleted files can only be restored within a 10-day window, and download speeds are reported as among the slowest of major cloud storage apps.
Frequently Asked Questions
How much does TeraBox cost in 2026?
TeraBox's Premium tier runs about 2.99 USD per month for 2TB of storage with ads removed and faster downloads, and a Premium+ tier is priced near 3.33 USD per month in some regions. A separate regional add-on pack for extra storage costs roughly 19.99 USD per year. There is no published enterprise or team-seat pricing, and exact amounts vary by country.
Is TeraBox free to use?
Yes, TeraBox's Free plan is permanent and never expires. The tradeoff is frequent full-screen ads, a 4GB cap on individual file uploads, throttled download speeds, and only a 10-day window to restore deleted files before they are gone for good.
What are the best alternatives to TeraBox?
Google Drive suits users already inside Google Workspace who want real-time Docs and Sheets collaboration, despite its smaller free tier. Dropbox fits teams that need polished Slack, Zoom, and Microsoft Office integrations plus document e-signing. pCloud and Sync.com are better picks for privacy-conscious users who specifically need zero-knowledge encryption, since TeraBox offers no client-side encryption.
How does TeraBox compare to Google Drive in 2026?
TeraBox wins on free storage capacity and bundles AI transcription and presentation tools at no extra cost, while Google's equivalent AI features sit behind a separate Google One subscription. Google Drive wins on trust and collaboration: it publishes SOC 2 and ISO 27001 certifications and integrates natively with Docs, Sheets, and Gmail. Pick TeraBox to maximize free personal storage; pick Google Drive for compliance-conscious team collaboration.
How do you get started with TeraBox?
Create a TeraBox account on the web or download the app for Windows, macOS, iOS, or Android to claim the 1TB free storage tier immediately. Start by uploading photos or video, or open the built-in AI Transcribe or Presentation Maker tools to turn an existing recording or prompt into text or a slide deck. Upgrading to Premium or Premium+ is optional and only needed for extra storage or an ad-free experience.
