goHeather
goHeather wins for boutique firms in 2026 because you can start without a sales call: published pricing ($400 a month, or $2,400 a year), a free trial with no card and cancel-anytime terms. It covers document summarisation, clause extraction and basic redlining on standard agreements, without drafting. Spellbook is the runner-up for firms drafting in Word (7-day free trial, prices by quote). LegalFly is the specialist where on-device anonymisation is a compliance requirement, with a catch: it publishes no prices and, per third-party reviews, needs a demo call before access.

Frequently Asked Questions
goHeather is the best AI contract review for boutique firms in 2026 for firms that want to start without a sales call: published pricing ($400 a month, or $2,400 a year) and a free trial with no card. LegalFly is the specialist where on-device anonymisation is a requirement, but it publishes no prices and, per third-party reviews, needs a demo call before access.
It depends on how many agreements you review. As an illustration, at $300 an hour the $200 a month annual plan is recovered by about 40 minutes of review time saved per month.
Generally no. Harvey is built for Am Law 50 firms with dedicated procurement and four-to-five-figure monthly budgets. For boutique firms, the pricing math does not work. LegalFly or Spellbook deliver most of the value at a fraction of the cost.
On-device anonymisation masks personally identifying information (client names, deal values, sensitive terms) on the lawyer's machine before any data is sent to the language model. This means the LLM never sees raw client data, satisfying GDPR Article 6 and most boutique firm confidentiality requirements without bespoke vendor negotiation.
Yes. One stack to consider is LegalFly for review of inbound third-party paper plus Spellbook for drafting outbound paper inside Word. Neither publishes prices, so a combined cost cannot be stated here; get both quotes before committing.
