- -Core "undetectable" and "cheat" positioning creates ethical, academic-integrity, and employment risk
- -The "undetectable" claim is contested; interviewers can spot behavioral tells
Spellbook
- +Native inside Microsoft Word, where transactional lawyers already work, so there is low workflow friction
- +Multi-model (GPT plus Claude) with citation-linked answers and playbook-encoded standards
- +Spellbook Associate extends from single-document copilot to supervised multi-document agentic workflows
- -Output requires lawyer review; like all legal LLM tools it carries hallucination and wrong-citation risk
- -Pricing is opaque (demo-gated), with reported enterprise rates high and rising and seat minimums
