Roadmap — v1.3

Here's what we're working on for the next major release. Expect v1.3 in Q2 2025.

  • Numerical Integration — integrate(f, a, b) for definite integrals
  • Function Plotting in Discord — PNG plot images directly in embeds
  • Batch API Endpoint — evaluate multiple expressions in one request
  • API Key System — authentication for high-volume API users
  • LaTeX Output — render results as formatted LaTeX in Discord embeds
  • Variable Persistence — store variables across a session with /set x = 5
  • Probability Distributions — normal, binomial, Poisson distributions
