Why students switch
The 3 ways ChatGPT quietly fails in study work
Every example below is a real failure mode students hit on academic prompts.

““71% of Earth's surface is ocean… approximately 79%.””
Truth: Lecture said 71%. ChatGPT rephrased and the figure shifted.
ThetaWave extracts numbers verbatim from your source — keeps them tied to the source.
Long-PDF truncation
“Detailed summary of chapters 1–4, then forgets chapter 7 ever existed.”
Truth: Context window cut off your 120-page reading.
ThetaWave indexes the full document and cites across chapters without dropping pages.

Frequently Asked Questions
Questions, answered
For study notes that need to match a real lecture or PDF — yes. ChatGPT generates from memory, so it invents citations and shifts numbers. ThetaWave only writes what your uploaded source says, and every line links back to the PDF page or transcript timestamp.
