Our philosophy
Teachers should stay in the loop.
I have taught English for more than fifteen years. I built The Alchemy Lab to connect what happens in a lesson with what students practice afterward and help teachers follow through.
The gap after the lesson.
My students were taking my courses, but they had no clear way to practice the content immediately afterward and get feedback. Some went off to practice with tools like ChatGPT. I could not see what they had tried, where they were struggling, or what advice they had received.
I wanted them to work on the sounds we had studied, use the language from a lesson, and rehearse situations they might actually face. I also wanted to see enough of that work to help them when we met again.
That became the starting point for Alchemy: activities connected to the lessons I was already teaching, with immediate feedback for students and a clear view of their work for me.
Learning, practice, feedback.
These three things belong together. A lesson introduces something; practice gives the student a chance to use it; feedback helps them see what to work on. The platform is built to keep that connection intact.
- Practice needs a purpose.A useful activity grows out of what the student is learning. The lesson gives it direction; the student's attempt shows what they can do with it.
- Feedback should lead to a next step.Students need to understand what worked, where they struggled, and what to try next. Feedback is most useful when it connects to the goal of the activity.
- The teacher stays in the loop.You can review the student's work and the feedback they received, then decide how to follow up. Your knowledge of the student and your relationship with them guide what happens next.
What that looks like in practice.
You build an activity around a teaching goal and share it with your students. They get feedback while the task is still fresh. You can review their responses and reports before deciding what to revisit, explain, or practice together.
- Practice pronunciation with feedback on the recording.
- Complete a speaking or writing assignment tied to your lesson.
- Use a level check to get an indication of their current English level.
- Rehearse a situation through a guided role-play.
- Choose the lesson context, task, and available evaluation criteria.
- Share activities by link or embed them on your course website.
- Review learner responses and the full feedback reports.
- Use that evidence to plan your next lesson or follow-up.
The judgment stays with you.
AI feedback can give students something useful to work with between lessons. It can also miss context or get things wrong. Level checks are formative estimates, and feedback reports need to be read with your knowledge of the learner in mind.
The teacher still chooses the learning goal, reviews the evidence, and decides what help the student needs next. That is why visibility matters as much as the feedback itself.
I built Alchemy for teachers who want to extend what they can do for their students beyond the lesson, while keeping the relationship at the center. I want it to help us follow through on our teaching and keep more of our weekends.
