Feature-by-feature
ChatGPT is a full-stack assistant: text chat, image generation, voice/video, web browsing, file analysis, code execution, deep research, agent mode, custom GPTs, projects, and group chats. Its latest move into advertising and a Linux desktop app show broad consumer reach. Spellbook is laser-focused on legal contracts: it applies AI redlines in Microsoft Word, auto-detects risks, drafts clauses, benchmarks market standards, and finds conflicting terms. Its new Associate multi-document agent handles due diligence across documents. Spellbook integrates with Word and iManage; ChatGPT hooks into Canva, Spotify, Zapier, Gmail, and more. ChatGPT’s image generation and deep research suit content creators and students; Spellbook’s playbooks and clause library serve transaction lawyers. If you need case law research, Spellbook isn’t for you; if you need contract redlining, ChatGPT lacks that specialized touch.
Pricing compared
Both are freemium, but the paid paths differ. ChatGPT’s free tier includes unlimited chats with GPT-5.6 Luna; paid tiers (Go, Plus, Pro) add advanced reasoning (Sol/Sol Pro), faster image generation, and larger context windows—Pro reaching 400K tokens, enough for ~250-page documents. Free tier now shows ads. Spellbook also has a free tier, but its premium features (Associate agent, Benchmarks, Playbooks) likely require a paid plan—you must book a demo, so pricing isn’t public. Spellbook’s $50M Series B suggests a serious enterprise product with corresponding enterprise pricing. For a solo developer, ChatGPT Pro (~$200/mo) is steep but powerful; Spellbook’s demo-gated pricing suits law firms that need certainty. If you’re a lawyer, Spellbook’s specialized value may justify a higher price than ChatGPT’s general plan.
