Frequently Asked Questions
Get answers to common questions about using Flexi in your classroom.
What if students use AI to cheat instead of learning?
Flexi guides thinking with hint-first prompts, step-by-step breakdowns, and follow-up questions. Flexi encourages students to think things through on their own, and you can specify whether the students can get direct answers or only Socratic-style thinking-aid questions.
Will AI take over my classroom or interfere with my teaching style?
You stay in charge. Choose what Flexi can do, and how it responds. Use it for scaffolds, examples, or practice while your routines and expectations remain the anchor.
I’m already stretched thin. Will setting this up take too much time?
Type what you need, and Flexi drafts it in seconds. Start with one lesson, warm-up, or exit ticket. No special training required.
How can I be sure my students’ data is safe with Flexi?
Flexi prioritizes privacy. It limits what is collected, uses secure storage, and follows school and district privacy requirements. No selling of student data. You have visibility into how it is used in class.
Can Flexi help me support students with IEPs or unique learning needs?
Yes. Ask for leveled versions, extra scaffolds, alternative formats, visuals, or enrichment. You set the goal, and Flexi adapts materials so you can meet students where they are.
Will Flexi fit into the curriculum I’ve worked hard to build?
Yes. Give Flexi your topic, standards, and the way you teach it. It creates examples, practice, and explanations that align with your scope and sequence instead of pulling you off course.
Does AI actually help students learn, or is it just another tech trend?
Flexi uses practices that improve learning: worked examples, deliberate hints, error analysis, retrieval and spaced practice, and metacognitive prompts. Teachers report stronger engagement and clearer explanations from students.
I already use so many tools. Why should I trust Flexi to make a difference?
Use Flexi where it saves you time immediately. Drafting problems and explanations, differentiating versions, generating feedback text, and turning your notes into materials. If it does not cut prep time or improve student responses, do not keep it for that task.
Is Flexi going to replace me as a teacher?
No. Flexi handles repetitive drafting and guided practice so you can focus on instruction, relationships, and feedback. Your judgment and classroom culture are the difference-makers.
What if my school or colleagues don’t trust AI yet?
Start small and transparent. Share sample outputs, show the prompts you used, set classroom guardrails, and invite a colleague to observe a short activity. Collect a few student work samples before and after. Let the evidence do the talking.
