How can we help?

Fastio is cloud storage built for teams that work alongside AI agents. Your files live in workspaces: permissioned, versioned containers owned by your organization rather than by any one person. From there you can search across everything, ask questions of your own documents and get cited answers, share folders and files with clients, and connect AI agents that read and write the same files your team does.

Sign up at go.fast.io/signup. Creating a personal user account is free. To actually store or share anything you need an organization, and every organization runs on a subscription. New organizations start on a 14 day trial, which requires a credit card so your workspace can keep running when the trial ends.

Your organization is the billed account. It owns the files, holds the member list, carries your branding, and keeps the audit log. A workspace is a permissioned container of files inside that organization, closer to a repository than to a personal drive. Because workspaces are owned by the organization and not by an individual, ownership can be transferred when someone changes role or leaves, and the files stay exactly where they are.

Create your organization, then create a workspace and put real files in it. Fastio indexes files as they arrive, so give it a moment and then ask a question about a document you just uploaded. Once that works, invite a colleague from Settings, then share a folder with someone outside your company to see the client side of it.

Open Settings, then Manage People, and invite by email address. Each plan includes a number of seats, and members beyond that are billed per additional user. You can also set an authorized email domain under Settings, then Authentication, so people from your company domain join the right organization.

Yes. The developer and API documentation lives at docs.fast.io, and the product pages on this site walk through each capability in detail. If you would rather be shown around, ask for a walkthrough using the support form on this page.

Start at go.fast.io/login and use the password reset link. The reset email arrives within a few minutes, so check your spam and quarantine folders before trying again. If your company mail server blocks external senders, that is usually the cause. Two other things catch people out: signing in with a different email address than the one you were invited on, and being removed from the organization you are trying to reach. If none of that applies, use the support form on this page and tell us the exact email address you are using.

Open Settings, then Profile. Your name and photo are what teammates and clients see next to your activity, so it is worth setting them properly before you start sharing with people outside your company.

Under Settings, then Authentication, you can set an authorized email domain so that people signing up on your company domain land in your organization. Member roles and permissions are managed under Settings, then Manage People. Single sign-on and SAML are not available today.

An organization owner can remove any member from Settings, then Manage People. To close your account entirely, or to request deletion of your personal data, follow the process on our data deletion page. Deleting an organization also removes the files it owns, so export anything you need first.

Yes, always. You can download files and folders from the web app, mount your workspaces on your Mac with the desktop app and copy them anywhere, or pull them programmatically through the API or CLI. Your files are yours, on any plan, including during and after a trial.

Starter is $29 per month, or $24 per month billed annually, and includes 5 seats, 1 TB of storage, and 300,000 AI credits. Business is $99 per month, or $83 billed annually, with 20 seats, 10 TB, and 1.2 million credits. Growth is $299 per month, or $249 billed annually, with 50 seats expandable to 200, 50 TB, and 4.5 million credits. Additional seats beyond the included count are billed per user.

There is no permanent free tier. Creating a user account costs nothing, but an organization needs either an active 14 day trial or a paid subscription. The trial requires a credit card so that your workspace continues without a gap if you decide to stay.

The trial runs for up to 14 days, or until your trial credits run out, whichever comes first. At that point the plan you selected activates automatically and billing begins, so your workspace keeps running. You can change plan or cancel at any time before then, and your files remain yours to export either way.

Credits meter AI work only. They are consumed by token usage, at roughly one credit per one hundred tokens, when you ask questions of your files, run extractions, or have an agent do work for you. Storage and seats are not metered in credits, they come with your plan. If you use more than your plan includes, overage is billed at $10 per 100,000 credits. Anything on this site or elsewhere that quotes a per gigabyte credit rate for storage or bandwidth is wrong: there is no such rate.

Open Settings, then Billing. The Summary tab shows your current plan, billing period, billable users, and credits consumed. Workspace Usage breaks storage down by workspace, and Credit Usage shows where your AI credits went.

Settings, then Billing, then the Invoices tab. Every invoice on the account can be viewed and downloaded there. If you need an invoice reissued with a different company name, VAT number, or billing address, use the support form on this page and tell us which invoice.

From Settings, then Billing, use the upgrade option to move between Starter, Business, and Growth. Adding people beyond your included seats is done from Settings, then Manage People, and the additional seats appear on your next invoice.

Open Settings, then Billing. At the bottom of the Summary tab there is a Danger Zone with a Cancel Subscription button. Only the organization owner sees it. Cancelling takes effect at the end of the current billing period, so you keep full access until the period you have already paid for runs out. Nothing is deleted at the moment you cancel, but export anything you need before your access ends.

Subscription fees are non-refundable except where our Terms of Service say otherwise or where the law requires it. If you are a consumer in the European Union or the United Kingdom you may have a 14 day right of withdrawal under the Consumer Rights Directive, unless you expressly consented to immediate provision of digital content and acknowledged losing that right. If you think you have been billed in error, or you were charged after intending to cancel, contact us using the form on this page before disputing the charge. We would much rather sort it out directly, and we can usually do it the same day.

Payments for Fastio are processed by Stripe on behalf of Fastio Inc. Charges recur automatically on the plan and billing period you chose, monthly or annually, until the subscription is cancelled. If a charge looks unfamiliar, it is most often an annual renewal, or a colleague on your team who set the account up. Send us the date and amount, plus the last four digits of the card, through the form on this page and we will identify it and resolve it. Please do that before filing a dispute with your bank, because a dispute freezes the account while it is investigated.

Major credit cards, processed through Stripe. For high volume accounts, or accounts flagged by our risk checks, we may require payment by ACH or prepayment of credit before service is consumed. That is decided case by case as part of fraud prevention.

Update the card on file under Settings, then Billing, and the outstanding invoice retries automatically. Cards most often fail because they expired, because the issuing bank blocked a recurring international charge, or because the billing address does not match. If it keeps failing after the card is updated, contact us through the form on this page rather than repeatedly retrying.

Drag and drop into the web app, save straight into a mounted workspace with the Mac desktop app, push them with the CLI or the API, or let an agent write them for you. You can also bring in files from a public URL as a one-time import.

Yes. For Dropbox, Box, and OneDrive you can connect the account and keep a remote folder in step with a Fastio folder, either on a schedule or on demand, one way or two way. For Google Drive you can import your files today, and continuous sync is coming. Connections are made per user rather than per organization, so the person who connects an account is the one whose access keeps it running.

Large uploads are the usual culprit. Keep the browser tab open and awake while it runs, since sleeping laptops and closed tabs interrupt transfers. Corporate VPNs and proxies also break long uploads, so try without the VPN if you can. For anything very large, or for a big batch, the desktop app and the CLI are more reliable than the browser because they resume rather than restart. If a specific file fails every time, tell us its name, size, and type through the support form.

Every file in a workspace keeps its version history, so if a file was overwritten you can open it and restore an earlier version. If a file or folder was deleted outright and you cannot find it, contact us through the form on this page quickly, with the workspace name and the file name, and tell us roughly when it went missing.

Search combines exact keyword matching with semantic matching, so you can find a file by its filename or by what it is actually about. You can also search by extracted metadata values, for example every contract with a particular counterparty, and preview which files match before you run anything expensive across them.

Metadata Views pull typed fields out of your documents, such as parties, dates, amounts, or reference numbers, and put them into a sortable table across a whole folder. They are available on every plan, and they can be set to run on new uploads so the table fills itself in as files arrive.

There are three. A file share sends a single file, either as a durable link or one that expires, with per-recipient access and version history. A shared folder gives someone the full app experience inside one folder, with granular permissions. A branded portal gives clients a polished space of their own, with your branding, where they can browse what you have published and ask questions about the content.

No. People you share with can open a link and work with what you sent without creating an account or paying anything. Your seats cover your team, not your clients.

You can set an expiry date, require a password, restrict downloads, and grant access to named recipients rather than to anyone holding the link. Every access is recorded in the audit log, so you can see who opened what and when.

Check three things in this order. First, whether the link has expired. Second, whether it is restricted to specific recipients and they are opening it from a different email address than the one you granted. Third, whether a password is set and they were never given it. If all three look right, send us the link through the support form and we will look at it from our side.

Yes. Under Settings, then Branding and Customization, you can set the logo and styling that clients see on portals and shared links.

Every workspace has AI built in. Files are indexed automatically as they arrive, and once a file is indexed you can ask questions about it and get answers that cite the source. Answers are drawn from the current version of each file. If you need an answer from an older version, attach that specific version to the question.

Indexing takes a moment after upload, and very large files take longer. If it still cannot see the file after a few minutes, check that you are asking inside the workspace that actually holds it, since chat is scoped to a workspace or a share rather than to your whole organization. Scanned documents with no text layer and unusual file formats are the other common causes.

Fastio speaks MCP, so agents like Claude, ChatGPT, Gemini, Cursor, and OpenClaw can connect to your workspaces directly. Point your client at https://mcp.fast.io/mcp and authenticate with a key created under Settings, then API Keys. Every plan includes MCP, CLI, and REST API access.

Almost every failed connection is one of three things. The key is wrong or was revoked, so create a fresh one under Settings, then API Keys. The key does not have access to the workspace being requested, since keys are scoped. Or the endpoint is wrong: it is https://mcp.fast.io/mcp, and if your client sends an Authorization header use https://mcp.fast.io/mcp/key instead.

At docs.fast.io. The base URL is https://api.fast.io/current/, and the machine-readable reference for agents is at https://api.fast.io/current/llms/full/. Note that some older third-party write-ups reference an api.fast.io/v1 namespace. That namespace does not exist and never did, so ignore any example that uses it.

That is the intended flow. An agent can sign up and build out a workspace, then hand it to a person who creates or joins the organization and takes ownership. Ownership of a workspace is transferable, so nothing needs to be copied or rebuilt.

Yes, for macOS today, with Windows in development. Your workspaces mount into Finder and behave like any other folder, so the apps you already use can open and save into them directly. You choose what is kept on disk and what arrives on demand.

Yes. The CLI is available on every plan and is the most reliable way to move large batches of files, script routine work, or run Fastio from a server.

Under Settings, then Connected Devices, you can see every machine and client signed into your account and revoke any of them. Do this immediately if a laptop is lost or a contractor leaves.

Files are encrypted at rest with AES-256 and in transit with TLS 1.3. Workspaces are isolated from one another, access tokens are scoped, and every action taken by a person or an agent is written to an append-only audit log. Shared links support expiry, passwords, and download controls.

No, and we will not tell you otherwise. Fastio runs on certified infrastructure partners, including Google Cloud Platform and Cloudflare, and we build the controls described above on top of that, but Fastio itself does not currently hold those certifications. If your procurement process needs a specific attestation, tell us through the support form and we will be straight with you about what we can and cannot provide.

Access is determined by workspace permissions inside your organization, plus whatever you have deliberately shared outside it. Our staff do not browse customer content. If you ask us to investigate a problem in a specific file or workspace, we will tell you what access we need and why before we do anything.

Yes. Our DPA is published on this site, along with the list of subprocessors we use.

Follow the process on our data deletion page, which covers deleting your account, deleting organization data, and exercising rights under GDPR and CCPA.

For content abuse, follow the reporting process on our abuse page. For a suspected security vulnerability, use the support form on this page, choose the security topic, and describe the issue. Please do not post vulnerability details publicly before we have had a chance to respond.

Do a hard refresh first, since a stale cached build is the most common cause. Then try a private window with extensions disabled, because aggressive ad blockers and privacy extensions can break parts of the app. If it works in a private window, an extension is the problem. If it fails everywhere, and on a different network, tell us your browser and version through the support form.

Very large folders and very large individual files take longer, and so does the first AI answer on a freshly uploaded document while it is still being indexed. If ordinary browsing feels slow, test on a different network, since VPNs and corporate proxies are frequently the bottleneck. If it is slow everywhere, tell us which workspace and roughly how many files it holds.

The more of this you give us, the faster it goes: what you expected to happen, what actually happened, the exact error text if there was one, the name of the workspace or file involved, when it started, and whether it happens on another browser or machine. The form on this page asks for most of it already.

We aim to reply to every request within one business day, and we treat billing problems and anything blocking a whole team as urgent. Marking your request as urgent in the form genuinely moves it up the queue, so please save it for cases where it is true.
