Question: I need a tool that helps my kid build fluency in reading with phonics-based methods.

If your child wants to learn to read fluently using phonics-based methods, Ello is a good option. This adaptive reading companion is geared for kids in Kindergarten to 3rd Grade and comes in two subscription options, digital and physical, that combine the two. The app offers real-time help, gentle corrections and motivation as kids read aloud, using an AI engine that personalizes the reading experience to each child's level and interests. It's geared for phonics-based reading methods and decodable books that are proven to help kids develop fluency and a lifelong reading habit.

Another option is Khan Academy, a free online learning platform covering a range of subjects including reading and language arts. It's got a large library of materials and is personalized so students can learn at their own pace. The site is good for kids and parents, offering a wealth of high-quality learning materials and tools to help kids get caught up and improve reading skills. Teachers have been successful with it for years, so it's a good choice for building reading fluency.

You could also try Storyville, which offers AI-powered personalized bedtime stories that are interactive and immersive. Though it's geared more for storytelling, the educational content and personalization can help with reading skills and instill a reading habit. The service accommodates multiple child profiles and offers unlimited stories for a relatively modest monthly subscription.
