A 16-year-old girl pleaded guilty to terror offences after bomb making instructions were found on her phone.
The teenager from Manchester, admitted the charges at the city's Magistrates' Court.
The court heard the girl used her school IT system to source information on Jihadi John and images of Michael Adebolajo, Lee Rigby's killer.
She also had images of a dead child, IS executions, guns and knives and jihadi terror 'heroes', including Abu Bakr al-Baghdadi.
The girl spoke only to confirm her name and age and she pleaded guilty to two offences under section 58 of the Terrorism Act 2000. She was granted bail by Judge Khalid Qureshi, which includes a 9pm to 7am curfew, reporting to police three times a week.
There is also a ban on applying for travel documents or a passport and a ban on travelling outside England and Wales.
Judge Qureshi said: "The youth offending team will want to interview you and your family.
"It is very much in your interests you are open and honest with them about what's happened, if you are able to tell them why you got involved in what you got involved in.
"I will be asking you some questions directly about your conduct, your behaviour, why you think it has happened. I need to try to understand why this happened."
The schoolgirl was arrested in April following an investigation by the North West Counter Terrorism Unit which also led to the arrest of a boy, 14, who admitted involvement in a plot to attack police in Australia.
No evidence was found that the girl was aware or played any part in the Anzac Day plot or any plan to harm others, the court was told.
