Based on your search query, I believe MagicSchool AI and Pedagogical could be beneficial for you.
MagicSchool AI offers a content generation feature that allows for the quick creation of original, standards-aligned educational content. This could be used to generate essay prompts or outlines for your students. Additionally, its advanced proofreading feature could be useful in identifying writing issues in students' essays and providing constructive feedback.
On the other hand, Pedagogical has a specific feature called the "History A Level Essay Feedback Copilot" that can quickly provide feedback on student essays. This could be particularly useful if you're teaching History at the A Level. It also allows you to customize the kind of feedback each essay receives, including exam-level pointers, which could be beneficial in guiding your students' essay writing.
Both tools offer unique features that could assist you in generating and assessing essays. You might find it beneficial to use MagicSchool AI for generating essay prompts and Pedagogical for providing tailored feedback on the essays. However, please note that Pedagogical is still in beta, meaning it could have bugs or incomplete features.
I hope this helps! If you have any other requirements or need further assistance, feel free to ask.
