Tuba correction
Last summer my family and I went on a holyday1 to Greece. We has went2 to the beach every day and eat3 a lot of ice cream.
„y" becomes „i" + „day".
No auxiliaries in Past Simple.
Past, parallel to „went".
How it works

Transcription, correction, feedback, points. You decide what makes it into the grade.

AI correction for school and teaching
Built for teachers, but useful for other texts too: Tuba corrects photographed texts with markings and explanations.
Simply take a photo. Tuba transcribes handwriting and print before correction, feedback and grading are created.
Phone photo instead of retyping: read several pages, review marked corrections and reuse the result.
One email to sign up, one click to delete. Images disappear after correction, only the text stays in your account. EU hosting, no tracking pixel, no third‑party analytics.
Buy red pens once — leftovers never expire. If an analysis fails, they flow back automatically. No renewal, no newsletter without your opt‑in, no paywall that suddenly appears.
Tuba suggests, and the model gets things wrong — sometimes even on correctly spelled words. That is why the original and the suggestion sit side by side, every mark with a reason. Accept, adjust or reject — it is your call.
