If you want a service that uses Telegram to track your reading activity and offer recommendations, BookSlice is a good choice. This gamified book reader is a Telegram bot that lets you set personal reminders, keep daily challenges and track progress with streaks. It uses AI to provide in-context answers to questions about the books you're reading. With a one-month free trial and a $2 monthly subscription, it's a relatively inexpensive way to spice up your reading.
Another good option is The StoryGraph. The service tracks and analyzes your reading activity to offer personalized book recommendations based on your preferences, mood and themes. It offers features like tracking and insights, AI-based recommendations, mood-based discovery and reading challenges. You can import data from Goodreads and use a mobile app on the App Store and Play Store, with most features available for free and more personalized features available on a paid plan.
Lunabot is also an option, particularly if you want an AI assistant that works in a browser and Telegram. It offers translation, summarization and writing integration features, with a free tier and several paid tiers to choose from. Lunabot can be triggered with Siri voice commands and works with multiple browsers, so it's a good option if you want to boost productivity and efficiency.
