I am currently building a directory which features a carefully curated list of free AI tools (or AI tools with good free plans).

Here's the list of free AI tools for students - https://www.freeaitools.fyi/tools/students

You'll discover AI tools for essay writing, academic writing, article writing, academic research, productivity, data analysis, AI detection tools (to ensure your AI write-ups are not detected), AI tools for creating PowerPoint presentations, excel etc.
