The primary cost of usage in Explorer is charged by volume, i.e. number of texts.

Each row in an file uploaded to Explorer is counted as one credit in the system. To be able to explore a file of a given size, you must have sufficient credits in your account.

Here is an example file:

In this case, exploring the column "review" would be 20 rows or 20 texts, which in turn would require 20 credits to carry out the analysis.

More specifically:

  1. Explorer accounts are monthly subscriptions, paid for in advance.
  2. The number of credits included in Explorer every month depends on the plan you chose.
  3. These plans are different prices, have different features and include a different monthly top-up of credits. (See details here).
  4. Extra credits can be bought at any time. These are priced according to the size of the batch purchased. Larger batches are cheaper.
  5. Credits never expire.
  6. You can upgrade or downgrade (or cancel) your plan at any time and the effect will be instant. If you upgrade, you will have to pay the difference between your new plan cost and the old plan cost. If you down-grade you will not get a refund, but your next scheduled charge, at the end of the account period, will reflect your new plan.


  1. Starting a project means you have uploaded a set of data (like above) and use credits to begin exploring your text data
  2. Projects take up a project slot, depending on your plan you have a certain limit of project slots.
  3. Additional projects will be an additional charge, depending on your subscription.

Please note:
  • The credits are charged to you account when you select the column for analysis and proceed to explore (rather than at the moment of upload).
  • Texts appended to an existing project are charged right away, however.
  • Empty rows are charged normally. If you don't want to be charged for these, you should clean them from your input file.
  • You may access your projects fully for one billing period after you cancel or stop paying for your account (but you won't be able to start new projects or append new data to the existing projects).
  • You will have limited access to your projects (data export only) for another 3 months after you cancel or stop paying for your account. Then your account and all its data will be deleted. Please tell us if you want us to delete your account before that.
  • If your organization is using manager/managed accounts (where one account handles the billing and all associated secondary accounts share its credits) there are special rules below.

Managed accounts:

  1. The main account (the manager) has to have a payment method configured (either credit card or invoicing) and must be on a Large plan.
  2. The manager can invite other users accounts to be managed. They have to exist and they have to have logged in at least once.
  3. If a user accept an invitation to be managed, that user will be managed by the manager. This means that:
    1. The manager is the only account required to pay.
    2. Each managed account will also be charged as a Large account.
    3. The managed account will share the manager account's credits with the manager and any other managed accounts.
    4. The default monthly top-ups for each account will appear in the manager account. (So a manager account with 2 managed accounts would receive 3*1200=3600 monthly credits).
    5. Any extra credits purchased in a managed account will be charged to the manager's account.
    6. These circumstances continue until the manager or the managed user disconnects the accounts (done through the Account page).
    7. When a managed account is disconnected from a manager it reverts to a normal account and normal payment responsibilities are applied again. To protect the managed user from unwanted charges, the user has to explicitly and manually re-activate the account for this to happen. If the managed account user does not re-activate the account it will be left in a canceled state and the above information for unpaid accounts will be in effect. Any responsibilities of the manager are also ended when a managed account is disconnected.
