Tandem GPT

What is Tandem GPT?
Tandem GPT puts you in realistic back-and-forth chats with an AI partner so you practice speaking a language, not just memorizing words. Pick from pre-built scenarios or write your own, then talk by text or voice message whenever you have a few minutes. The homepage advertises 24/7 access so sessions fit commutes or late-night study blocks.
Most language apps optimize for vocabulary drills and grammar exercises. Tandem GPT bets on open-ended dialogue, which is closer to how you actually need to speak when traveling or working abroad. You trade structured lesson progression for scenario flexibility, and the built-in voice messaging pushes you past typing-only comfort zones. The team notes they are evolving the product into Parlai, a separate app linked from the homepage.
Self-directed learners and busy professionals use Tandem GPT when they want conversational reps without booking a human tutor every week. Juan and Felipe, two Colombian software engineers based in Austria, built it after struggling with German immersion. The site reports more than 8,000 AI conversations and 900 new users, with a free entry point at tandem-gpt.com/new.
PrepAI

What is PrepAI?
PrepAI turns lesson notes, PDFs, documents, web links, and videos into quizzes and test papers for educators and trainers. Built by DataToBiz, it offers Standard, Subject, and HOTS quiz modes, academic question banks, and LMS export so teachers can generate assessments without writing every question by hand.
Many quiz builders stop at multiple-choice recall. PrepAI adds HOTS mode aligned to Bloom's taxonomy, a Smart Variations Generator for parallel quiz versions, hosted online assessments with auto-grading, and a REST API for LMS integration. That stack targets schools and training teams that need drafting, delivery, and grading in one workflow.
Teachers, corporate trainers, and EdTech teams use PrepAI to cut assessment prep time. The India pricing page lists a free trial on signup, credit-based solo practice, subscription tiers up to 3,000 quizzes per year, and API access for developers integrating quiz generation.
