Spellbook
The easiest install in the category: a Word add-in that drafts and redlines where fee-earners already work. The trade is a thin evidential trail.
Tier C — watch. Brilliant ergonomics and a low barrier to entry, which is precisely why it spreads before it is governed. For a firm that must show its work, 'the tool wrote it in the document' is not yet a record. Pilot with a strict no-client-data rule until the logging convinces you.
What it does
Clause drafting, redlining, contract review and suggestion generation inside Microsoft Word.
Where it holds up
- Works inside Word — no new destination to learn
- Fast clause-level suggestions with useful redlines
- Low cost per seat relative to enterprise platforms
Where it doesn't
- Weak audit trail on what the tool changed and why
- Data posture questions need direct answers, not marketing copy
- Review discipline is entirely on the user
Data posture, as documented
What the vendor's own material and terms say — and where the answer was not published, we say so rather than guess.
| location | US/EU hosting; confirm region |
| training | Tier-dependent — establish the position in writing |
| retention | Not prominently documented; ask |
| subprocessors | Ask for the current list before signing |
What it costs, realistically
Per-seat subscription; low entry point, annual commitment.
Who it suits
Small teams that want an immediate drafting uplift on non-confidential work.
Client-confidential drafting until the evidence trail is documented.
How we assessed it
Documentation review; the transparency score reflects absent public logging detail.
