NOT REALLY
why this verdict
Keep paying — Anthropic has not replaced it
Anthropic's version overlaps, but does not finish the legal job, so this one still earns its $129/mo.
- A named launch, not a vibe named, unlinked
- Built on frontier models rather than against them. Anthropic, June 25, 2024 — no announcement link recorded yet.
- How much of the job it covers not the job editorial call
- Parts of it. The job still needs the tool to get finished.
- Is there a free way to do it? yes
- 1 of 2 listed replacements have a usable free tier: Claude.
- What the call is worth $1,548/yr
- $129/mo at the entry paid tier — $1,548 a year per seat.

The backstory
Spellbook drafts and reviews contracts inside Microsoft Word, where lawyers actually work. Rather than competing with frontier models it packages them with legal-specific prompting, precedent libraries and the redlining workflow. Being AI-native turned out to be the safest position in legal tech.
