Description

Merlin AI (by Foyer Inc) is an all-in-one AI assistant, delivered as a Chrome extension, web app and mobile apps, that puts GPT, Claude, Gemini, Llama, Mistral and Perplexity behind a single subscription and lets you summarize pages, YouTube videos and PDFs, draft in Gmail, and generate images without switching tabs. It's aimed at individuals, freelancers and small teams who want casual-to-moderate access to multiple premium models without paying for each one separately. Its main differentiator is model aggregation in the browser: rather than committing to one provider, users switch between frontier models in-context and split the cost of many subscriptions into one.

CastReader is a text-to-speech reader available as browser extensions and mobile and desktop apps. It reads webpages, PDFs, Kindle books and AI chatbot answers aloud with synced highlighting.
