CastReader vs Read&Write
Read&Write Needs a School License. CastReader Is Free for Everyone.
TextHelp Read&Write is the K-12 standard — but it costs schools $143/seat/year and students can't use it on personal devices. CastReader gives any student free TTS with paragraph highlighting, Kindle textbook reading, and AI chat support.

Why Choose CastReader Over Read&Write
K-12 literacy toolbar by TextHelp with TTS, dictionary, and writing tools? Here's what CastReader does differently.
No License Required
Students Can Install It Themselves
Read&Write requires a school or district license — students can't use it on personal devices unless the school pays. CastReader is free for everyone. Any student installs it from the Chrome Web Store and starts listening in 10 seconds.
Better Voices
AI Voices vs Browser Speech
Read&Write primarily uses browser speech synthesis voices. CastReader uses Kokoro AI — a purpose-trained TTS model that sounds natural, handles emphasis, and makes long reading sessions comfortable.
Kindle Textbooks
Read Your Kindle Textbooks Aloud
Many students buy textbooks on Kindle. Read&Write cannot read Kindle Cloud Reader — CastReader is the only extension that can, using OCR to bypass Amazon's encrypted fonts. Also works on arXiv papers and Google Docs assignments.
Frequently Asked Questions
CastReader vs Read&Write — common questions
Can CastReader replace Read&Write for students?
For text-to-speech: yes. CastReader offers better AI voices, paragraph highlighting, and works on more platforms (Kindle, ChatGPT, arXiv). However, Read&Write also includes a dictionary, picture dictionary, writing tools, and text highlighting — features CastReader doesn't have. For pure TTS, CastReader is better and free.
Does Read&Write work on Kindle?
No. Read&Write cannot read Kindle Cloud Reader because Amazon uses encrypted fonts. CastReader is the only Chrome extension that works on Kindle, using OCR technology.
Is CastReader approved for IEP/504 accommodations?
CastReader provides TTS functionality that meets common IEP and 504 accommodation requirements for text-to-speech. However, it doesn't have district admin dashboards or usage reporting. Schools that need compliance tracking may still need Read&Write for administration alongside CastReader for student-facing TTS.
Can students use both?
Yes. Use Read&Write in school (if the district provides it) for its writing tools and dictionary, and CastReader at home on personal devices for TTS reading. They don't conflict.
Does CastReader have a dictionary like Read&Write?
No. CastReader is focused on reading aloud with paragraph highlighting. For dictionary lookups, use a separate extension or Read&Write if available. CastReader pairs well with dictionary extensions.
