B27 Escola: Brazilian AI Tutoring Platform - Sell Project

B27 Escola helps Brazilian students study school subjects, practice exercises and prepare for exams through a live AI-powered platform in Portuguese. It brings everyday study tools together in a responsive web interface. WHAT STUDENTS CAN DO • Explore subjects through guided explanations and questions. • Practice exercises and use mock exams. • Access English and writing support. • Copy, print or save responses as PDF. SEE THE PRODUCT WORKING The gallery shows real study workflows, exercise feedback and mock exams, including a Volume explanation and a History answer linked to a Senate source. New screenshots show a student explicitly asking for help and the resulting step-based explanation. Buyers can also explore the live demo and its public validation panel. The platform also features an interactive robot that uses colors and expressions to indicate system status. Clicking it displays verification results, resolved reviews and pending issues, making the continuous monitoring process visible to users. RECENT PROGRESS B27 now reuses previously verified answers and retrieves documentary evidence to support factual checks. A documented update resolved 48 historical pending reviews across four answer families, preserving the original records and review history. These are targeted improvements, not a platform-wide accuracy guarantee. October 25 update — Contextual Sensitivity A first contextual adaptation is now integrated into the existing core, preserving the six-engine architecture. It recognizes selected explicit statements of difficulty or frustration at the start of a study request, keeps the question on topic and guides generated explanations toward smaller steps and concrete examples. Curated facts and sources remain preserved. This is a bounded first version, not a claim of general emotion recognition. The update passed 62 local checks and two live study examples. Exercise handling also improved: students can submit five numbered answers in one message, even when line breaks are removed. A live Chemistry test recognized all five answers and returned 5/5. These results apply to the tested workflows. WHAT THE BUYER GETS An operating product with source code, a knowledge base displaying over 161,000 stored records, interface assets, AI integrations, scheduled workflows, documentation and transfer assistance under the existing sale package. PHP, JavaScript, SQLite and six existing engines provide the technical foundation. CURRENT STAGE B27 is a working, pre-revenue educational platform with a live demo and documented improvements in source-linked answers, answer reuse and validation workflows. It offers a practical foundation for a buyer to develop further with Brazilian education expertise, content and distribution. Development continues to broaden coverage and refine the learning experience; verified results apply to the tested cases, with longer-term performance still being assessed.
