Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Photomath

  • Full free step by step solutions make it straightforward for a student to submit copied working without doing the reasoning themselves, which is a real concern for teachers assigning homework.
  • Word problems, a common school assessment format, are gated behind the Plus subscription, so the free tier is weaker on exactly the problem type many students struggle with most.
  • Camera recognition of messy handwriting or complex notation such as matrices or multi-line proofs is unreliable, and misreads produce confidently wrong steps.
  • Since the 2022 Google acquisition, the product sits inside a company whose primary business is advertising and data, which is a relevant factor for schools with strict student data policies.
  • It solves problems rather than teaching underlying concepts from scratch, so a student with no foundational understanding gets a worked answer but not necessarily comprehension.

Replit AI Agent

  • Agent performance varies and becomes slower with larger projects
  • Unpredictable credit costs and billing, with users reporting bill shock
  • Usage-based credits burn faster than expected, making pricing unpredictable
  • Support response times are weak on critical issues
  • Interface still feels like a developer tool rather than beginner-friendly
