Questions

The short answers, with the same rule the rest of this site follows: nothing is claimed that is not built. If something here is wrong, tell us.

• Is Sparkslingo free?

  Yes, and there is nothing to buy. Sparkslingo is free while it is in active development: no pricing page, no plan to choose, no card to enter.

• Which languages can I use?

  You write in the language you are learning and read the explanation in the one you already speak, and both pickers offer the full ISO 639-1 set. English is the only language whose reviews a human has read so far. The picker says "Tested so far: English" where you choose.

• Does the AI correct me while I write?

  No. A review starts only when you ask for one, after the thought is finished. Nothing is corrected in the background and nothing runs on a schedule.

• What does the AI actually see?

  For a review: the text of that journal and the two languages, the one you are learning and the one you read explanations in. When a correction becomes an exercise, the corrections drawn from your own sentence are sent too. Nothing else in your account is.

• Does the review change my writing?

  No. Your original is kept exactly as you wrote it and the reviewed version is shown beside it. Every change is something you can open and read the reason for.

• Which devices does it work on?

  iOS, Android and the browser, from one app. Your journals, corrections and practice are the same wherever you sign in.

• Can I delete what I have written?

  Yes. A single journal can be deleted in the app. Erasing your whole account (journals, reviews, corrections, exercises and sessions) is an email request for now, and the contact page says how.
