goHeather
goHeather is the pick on transparency: it is the only tool here you can price and start without a sales call. Contract review software is priced two ways in 2026: published plans and quotes. goHeather is the only tool here with a published self-serve price, at $400 a month or $2,400 a year on its Starter plan, with a free trial and no card. Spellbook prices by the number of team members on a licence, publishes no rates and offers a 7-day free trial. Definely is quote-based, and LegalFly and Harvey prices could not be verified for this guide. The practical rule is to get quotes against your own seat count and contract types before committing, and to treat any per-seat figure quoted without a source as unverified.

How This Was Tested
The goHeather and Spellbook pricing pages were read in October 2026. LegalFly and Harvey prices could not be read, and Definely and other enterprise tools are quote-based, so no price is quoted for a tool whose page was not read. Performance and fit judgements are editorial opinion based on vendor documentation, not measured results or independent benchmarks.
Frequently Asked Questions
Published self-serve pricing is rare in this category. goHeather lists $400 a month or $2,400 a year on its Starter plan, Spellbook prices by team size on a quote, Definely is custom-quoted, and LegalFly and Harvey prices could not be verified for this guide.
It depends on how much review time the tool saves and what the quote is. As an illustration, at $300 an hour a $200 a month annual plan is recovered by about 40 minutes of time saved a month. Check the maths against your own volume before subscribing.
The gap reflects what the vendor takes on rather than what the software does. Self-serve tools ship standard terms, shared tenancy and no negotiation. Enterprise quotes include dedicated tenancy, custom data-processing terms, procurement support and named-account service, which firms below the largest tier rarely need.
A combined tool is usually simpler, because lawyers do not move between two apps. Splitting the stack only makes sense when a specific requirement, such as on-device anonymization, is only available in a review-only product. Price both options from quotes against your own seat count.
Typically 10 to 20 percent. Pay monthly for the first quarter regardless. Playbook quality and document-type coverage only become clear after a few real matters, and switching after an annual prepayment means eating the balance. Move to annual once the tool has handled a full quarter of your actual contract mix.
Free tiers exist but cap document counts at levels a real caseload passes in days, and general-purpose AI chatbots lack the legal-specific playbooks that make redlining reliable. The lowest published professional price in this guide is goHeather at $200 a month on annual billing.
