Frequently asked questions
Honest answers about what Atomly is and isn't.
- What is Atomly? +
- Atomly is an AI chemistry and biochemistry tutor for university students. Unlike general-purpose AI chatbots, Atomly's tutor Clara grades your answers point-by-point against an explicit mark scheme — the way a real tutor would. It covers organic, inorganic, physical, analytical, and biochemistry topics from first year through MSc level.
- How is Atomly different from ChatGPT or Claude for chemistry? +
- General AI chatbots explain concepts but they don't mark exam-style answers against a mark scheme. Atomly does: every Grader response shows your score per criterion, what you nailed, and exactly where you lost marks. It's also calibrated to a chemistry undergraduate's level and built by an MSc chemist, with strong opinions about getting curvy arrows, stereochemistry, and mechanism conventions right.
- Who is Atomly for? +
- Undergraduate, MSc, and early PhD chemistry and biochemistry students at any university. The tools are calibrated for university level — not high school, not research chemistry.
- What can I do with Atomly? +
- Five tools, all included on every plan: (1) Grader — get marked on exam-style questions across 19 topics; (2) Mechanism Explainer — step-by-step mechanisms with curvy-arrow electron flow; (3) Concept Q&A — chemistry-focused chat with exam-answer summaries; (4) Biochemistry Pathway Explainer — metabolic pathways enzyme-by-enzyme; (5) Paper Helper — summarise or search PDFs.
- How much does Atomly cost? +
- Three monthly plans, all in USD: Starter $5.99/month (200 credits), Standard $9.99/month (1,000 credits, most popular), and Pro $14.99/month (1,700 credits). Each tool has a fixed credit cost — Grader 20, Mechanism 50, Q&A 10, Pathway 15, Paper summary 15. Cancel any time.
- Is Atomly accurate? +
- Atomly uses top-tier AI models (Claude Opus for grading and mechanisms, Claude Sonnet for Q&A and pathways) and is built by an MSc chemist who tunes the prompts for chemistry accuracy. That said, AI can still make mistakes — Atomly always tells you to verify critical answers against a textbook or your tutor before relying on them.
