Additio App vs Gradebox

Additio App is a formative assessment and daily classroom management platform for teachers and educational centers. Teachers Standard provides a customizable gradebook, educational monitoring and planning, assessment tools, attendance records, class scheduling, and student progress reports. Assessment options include customizable rubrics, self-assessment, peer assessment, skills-based assessment, and formative feedback. Teachers Pro AI adds an AI chat assistant, AI-generated customizable rubrics, AI-assisted lesson planning, and new AI features during the school year. Additio App integrates with Google Classroom, Microsoft Teams, and Moodle, and offers an API. Users can export data in Excel format at any time. The company says it follows GDPR and Spain’s Organic Law 3/2018, uses Hetzner and Amazon servers with 256-bit encryption, and does not sell or reuse customer data for other purposes. Teachers Standard costs €13.99 a year; Teachers Pro AI costs €29.99 a year, both VAT included.

Gradebox digitizes physical student assignments and provides feedback for teachers. Teachers can scan work with a mobile device; Quick Scan OCR reads student names and matches submissions to its internal gradebook. AI analyzes student work and drafts instructional feedback, while teachers review and approve recommended grades. Teachers can also grade by hand or digitally, or scan work that has already been graded. For unnamed assignments, Gradebox can suggest likely students by comparing the roster with earlier submissions for teacher review. The current app supports CSV grade exports; API integrations with popular systems are planned, and home submissions are still in development. Gradebox is intended for teachers and school administrators, with parent and guardian access to student work and feedback. Its terms say Student Data is not sold or used for targeted advertising or behavioral profiling, and is not used to train or improve AI models by default. The free plan costs nothing and covers one classroom and 120 single-page assignment submissions or grades per month. Pro costs $11.99 a month, with an annual commitment and cancellation before renewal.
