Bangla-native AI research lab building sovereign, low-resource models and on-premise infrastructure
Trains its own Bangla language, speech and multimodal models rather than only fine-tuning existing weights, including the 0.8B-parameter Sangbad-SLM news model.
Designs on-premise and private-cloud inference pipelines, MLOps, data governance and compute strategy so institutions run models on their own servers and data.
Research and pretraining techniques tuned for limited compute budgets, so capable models stay affordable to build and to operate at national scale.
Document intelligence, computer vision, predictive modelling and retrieval-augmented assistants delivered as working systems and evaluated against real-world data.
Turn any text, PDF, image or book into lifelike AI speech
Voices trained on large language models deliver lifelike delivery, while Content Aware voices read the text and adjust tone to fit the material.
Speak in over 90 languages and create a custom multilingual AI voice by uploading or recording your own.
Read PDFs, Word documents, ePub, web pages and images, and scan physical books with the built-in OCR camera scanner.
Turn long readings into AI podcasts, get instant recaps, analyse screenshots and equations, chat with your document and generate practice quizzes.
