Your personal AI tutor for every subject, from notes to exam day.
Upload your notes, slides or past papers, set your exam date and target grade, and Astra assembles a topic-by-topic revision plan built around exactly what you'll be tested on.
Ask by typing, speaking or snapping a photo. The tutor explains concepts at your level, asks follow-up questions and keeps going until the idea actually clicks.
Generate guided lessons, flashcards, quizzes, true/false and smart-text exercises, plus an auto-generated podcast so every learning style is covered.
Practise with realistic oral and timed written mock exams that get graded, so you know where you stand before the real thing.

Describe the data you want in plain English and Chat4Data explores the page, picks the right fields and works through pagination and clicks.
The AI reads both how a page looks and how it is built, so it keeps finding the right data even when layouts shift or the underlying code changes.
When a site asks for verification or a login, Chat4Data pauses and hands control to you, then resumes exactly where it stopped so no run is wasted.
Images, links, emails, phone numbers and hidden elements are captured in the same run, then exported ready for analysis.
