TeraBox is a consumer cloud storage service that gives 1024GB free on signup, with cross-device backup, link sharing and paid tiers for larger files, and it has since added an AI layer covering slides, notes, transcription, PDF conversion and image generation. It suits individuals who need capacity cheaply rather than teams needing enterprise controls.

TeraBox is a high-capacity cloud storage service designed for individuals, and that self-description is worth taking at face value: this is a consumer product, not a business platform. The headline proposition is unusually blunt — 1TB of free storage capacity on signup, an allocation several times larger than what Google Drive, Dropbox or OneDrive give away. Everything else about the product follows from the economics of making that number work.
But describing it only as a cloud drive would now be out of date. Alongside storage, the company has built a substantial AI layer, marketed as an all-in-one AI productivity platform with its own navigation and product identity. That layer includes a general assistant called Tera AI, an AI notebook, three different modes of AI slide generation, image generation, video generation and speech-to-text, plus deep research and writing tools. A separate image product, TeraAIpix, ships with its own desktop client. TechRadar has reviewed TeraBox AI as a product in its own right, which is a reasonable signal that this is more than a marketing label.
The ownership question deserves a direct answer, because it is the single most searched thing about this service and most of what circulates online is second-hand. The company addresses it on its own About page: headquarters and R&D center are located in Tokyo, Japan, and its corporate timeline records that following the exit of certain board members, the business is fully held, managed, and operationally steered by the Japanese team. The operating entity named in the site footer is Flextech Inc. That is the company's own account of a change that did occur, rather than a denial that anything changed — which is the honest framing to carry forward.
Scale is large and self-reported. The About page cites 320 million registered users and 20 million daily active users across more than 231 countries, while the homepage carries higher figures still. Neither has been independently audited, and the gap between the two pages is a reason to treat any exact number as approximate rather than measured.
The free tier is the product's centre of gravity: 1024GB of storage at no cost, plus free AI trial credits, original-quality video playback and cloud unzipping. The pricing panel labels the free capacity as time-limited, which is worth verifying at signup rather than assuming it is permanent.
Paid membership is inexpensive by category standards. Premium is advertised at a $3.49 introductory rate against a $6.99 list price, raising capacity to 2048GB and adding 128GB large-file uploads and the encrypted vault. Annual billing works out lower per month. The company also lists a Premium Plus tier and separate capacity add-ons for users who need more than the standard allocation.
The renewal terms matter more than the headline. Monthly subscriptions renew at $3.49 a month after the introductory period, and the annual plan renews automatically at $35.99 a year. Introductory pricing is a discount on the first period rather than an ongoing rate, so the number to budget against is the renewal figure. The site also notes that actual prices are confirmed after login, meaning displayed rates can vary by account and region.
Beyond subscriptions, there is an unusual reverse cash flow: the referral programme pays users for new sign-ups, for views on shared videos, through advertising revenue share and through paid content sales. That structure explains a great deal about how the service is distributed, and about why public link sharing is so central to its traffic.
The certification position is documented and checkable. The About page states that parent company Flextech Inc. has been certified for ISO/IEC 27018:2019 and 27701:2019, following ISO 27001:2013 — a combination covering information security management, protection of personal data in public clouds, and privacy information management specifically. For a free consumer service, holding all three is more than most peers offer.
The technical description is specific rather than vague. The company states that the source data and file data are stored separately, and the sensitive marks are desensitized by encryption and digitization; personal files are split into different file blocks and stored on different servers. Transmission uses HTTPS, sharing defaults to extraction codes, and shared links are blocked from search engine indexing. These are meaningful protections against interception and casual discovery. What they are not is end-to-end encryption: the architecture described is one where the provider operates on your data, not one where it cannot.
The transparency reporting is the most unusual element and cuts both ways. The company published takedown figures showing it had taken down 1,294,285 public links reported to contain illegal and objectionable content in the first half of 2024, deleting 1,147 associated accounts, plus 462,762 links removed for copyright infringement, alongside a published takedown guidance policy describing how it balances user privacy against legal requests. Publishing these numbers is a genuine transparency practice. The numbers themselves are also evidence of the scale of misuse that a mass free-storage platform with public sharing attracts, and prospective users should read them as both reassurance and warning.
One practical limitation of this assessment: the full privacy policy and transparency report pages are served through a client-rendered shell that returned no readable text during research, so this section relies on the company's security page, About page and published reporting rather than on the policy document itself. Anyone with a compliance requirement should obtain the current policy directly.
Yes, on signup, and that allocation is the product's main draw. Two caveats: the pricing panel describes the free capacity as time-limited, so confirm the current terms when you register, and the free tier carries advertising plus bandwidth throttling that paid tiers reduce.
The operating entity is Flextech Inc., and the company states that its headquarters and R&D center are located in Tokyo, Japan. Its own corporate timeline records that after certain board members exited, the business became fully held, managed, and operationally steered by the Japanese team. Third-party accounts of this history conflict, so the company's own record is the most reliable available statement.
Both, and the AI side is larger than most descriptions suggest. Storage remains the core, but the company has built what it calls an all-in-one AI productivity platform with a general assistant, AI notebook, three slide-generation modes, image and video generation, transcription, research and writing tools, and eight document conversions. TechRadar has reviewed the AI product separately from the storage service.
Not without your own encryption. The company documents strong server-side measures — HTTPS, access controls, and an architecture where personal files are split into different file blocks and stored on different servers — and holds ISO 27001, 27018 and 27701 certifications. But it does not claim zero-knowledge encryption, and independent reviewers explicitly advise using it with a reliable encryption utility. For financial, medical or identifying documents, encrypt locally first.
Because speed is throttled by design on the free tier. Independent testing found that none of TeraBox's competitors also seek to throttle users' bandwidth, and that this pushed measured upload speeds below Dropbox and OneDrive. It is the trade-off that funds the free terabyte.
Premium is advertised at a $3.49 introductory rate against a $6.99 list price, taking storage to 2048GB and adding 128GB large-file uploads, an encrypted vault, ad removal and more than 22 membership privileges in total. Note that monthly renews at $3.49 and the annual plan renews automatically at $35.99 a year, so budget against the renewal rate.
Web, Windows desktop, Android including a direct APK download, and iOS. Backup and sharing work from the desktop app, mobile app or the web with changes syncing across devices. Reviewers have noted the absence of a macOS client as a gap, so verify current availability if that is your platform.
Actively, and it publishes the numbers. Its transparency report states it had taken down 1,294,285 public links reported to contain illegal and objectionable content in the first half of 2024 and deleted 1,147 accounts, plus 462,762 links removed for copyright infringement. Publishing this is unusual and to its credit; the magnitude also indicates how much abuse a large free-sharing platform attracts.
There is a referral programme paying for new user sign-ups, video views on shared content, advertising revenue share and paid content sales. It is a real feature rather than a promotion, and it explains much of how the service spreads — though it is also the mechanism behind a substantial share of the platform's moderation workload.
Generally not. It is a high-capacity cloud storage service designed for individuals, without the admin controls, audit trails, retention policies or contractual assurances business buyers usually require. Teams with compliance obligations should choose a provider built for that purpose; individuals wanting affordable capacity are the intended audience here.
