goHeather vs LegalOn
Both review contracts against a playbook. They differ on where the playbook comes from and what else sits around it.
LegalOn and goHeather both review contracts against a written standard and produce redlines. LegalOn ships with a large library of attorney-built playbooks, named agents for intake, triage, drafting and translation, and a post-signature repository called Vault. goHeather builds the playbook from your own contracts and positions, and puts drafting from a description, its own document editor, e-signature and a choice of AI model in the same workspace as review. The choice comes down to two things: whether you'd rather start from LegalOn's playbooks or your own, and who on your team will use the tool every day.

goHeather vs LegalOn at a glance
| Compared | goHeather | |
|---|---|---|
| Where it runs | A web app with its own Word-style editor, and a Microsoft Word add-in. Work with Word, PDF and scanned documents in most languages, keep several documents in one chat, and connect other systems through a REST API and webhooks. | Microsoft Word or the browser, with .docx and PDF files. |
| Contract review against your own standards | Yes. One click starts a review: goHeather identifies both parties, your side and the governing law, and you choose how deep it goes, from deal-breakers only to every issue. It runs a standard review and checks the contract against your playbook, then lists each finding as High, Medium or Low risk with the original clause, a suggested redline and a plain-English explanation. Apply, dismiss or flag each finding, or add it to your playbook. Later negotiation rounds can be reviewed redline-only, and Legal Summary, Deal Abstract and Negotiation memos export to Word. | Yes. Review flags risks and ranks them Low, Medium or High, with one-click redlines you accept or apply. Its Assistant adds inline citations and a preview of redlines before they are applied in Word. It handles first- or third-party contracts, playbooks are written for your role as sender or receiver, and Cross-Document Review (announced in LegalOn's August 2026 product update) reads amendments and side letters as context. |
| Who builds the playbook, and from what | You do. Generate a playbook from a contract you already use in about a minute, build one from scratch, or start from a sample, then edit it by describing the change. Each rule sets your position, with fallback positions, unacceptable deviations and guidance notes, and any finding can become a new rule. Playbooks can be private or shared with your team. On the Team plan, goHeather builds your playbooks for you, and on every plan free one-on-one sessions with a lawyer help you set them up. | Both. LegalOn ships "135+ playbooks built by our experienced attorneys" across NDAs, MSAs, DPAs, SaaS terms, leases, construction, clinical trial agreements and more, plus International Playbooks for NDAs and MSAs in 23 countries outside the US, reviewed by jurisdiction-specific attorneys. Custom playbooks come from a Playbook Agent that converts "contract templates, review guidelines, or prior redlines" into a playbook, from an Excel upload, or from plain English. Rules hold "preferred positions, fallback language, and risk tolerances." |
| Drafting a full document from scratch | Yes. Describe the document and goHeather asks a few questions (or makes the call for you), has you approve an outline, then drafts each section into an editable Word document and flags any section that needs a second look. Anything you didn't supply stays a labeled blank instead of being made up. It can work from your own templates and reference files, search the web while drafting, and produce memos, letters and tables as Word, PDF or Excel files. | A Drafting Agent "drafts and edits legal documents directly in Microsoft Word," and LegalOn ships 100+ market-standard templates and 100+ attorney-built prompt workflows across ten practice areas. |
| Edits delivered as tracked changes | Yes. Every edit arrives as a tracked change under your name, with a short comment explaining it to the other side, in the browser editor or in Word. Accept or reject changes one at a time or all at once, or just tell goHeather what to change. Each document keeps its full version history, and you can compare versions. | Yes. One-click redlines in Word or the browser that you accept or apply. |
| Where signed contracts live | In goHeather's contract list, with start, end and notice-to-terminate dates pulled from each contract automatically, obligation tracking, version history, and every review and chat about that contract. Documents can be sent for e-signature from goHeather. | Vault: "one home for every executed contract," with automatic extraction of key data into an editable table, auto-identified renewal and expiration dates, email notifications tied to contract terms, and import from DocuSign. |
| Choice of AI model | Yes. Pick the model for each chat from six current models from OpenAI, Anthropic and Meta, including GPT-6 Astra and Claude Opus 5.5, with unlimited use on every plan. If a provider is busy, goHeather switches to another model automatically. You can also train your own AI model on your organization's standards. | LegalOn's security page says it works with Microsoft's Azure OpenAI service. Its AI team publishes contract review benchmarks across GPT, Claude and Gemini models, and LegalOn says it aims to deploy the best model for each use case. Translation uses DeepL plus LegalOn's own agent, in 30 or more languages. |
| Agentic review(the AI plans and runs a multi-step review on its own, rather than answering one prompt at a time) | In beta. An agentic review mode runs reviews in chat. With email intake, you forward an NDA or any other contract and get it back in your inbox reviewed against your playbook, redlined with tracked changes, with a short memo. | Yes. LegalOn Agents are "specialized AI agents [that] execute defined legal tasks": Playbook, Intake, Triage (screens low-risk agreements and routes exceptions to an attorney), Drafting and Translation. |
| Contract lifecycle management, CLM(a repository of signed contracts with statuses, dates, search and renewals) | In beta. The Vault keeps a team's contracts, amendments, memos and email in one place, filed by AI into folders with per-folder access. Each contract shows its type, counterparty, key dates and status (Template, Draft, Out for signature, Signed, Expired, Terminated), with a Deadlines view, renewal reminders and search across contracts, reviews, playbooks and chats. | Vault covers the post-signature side: repository, extraction, renewal and expiration dates, and notifications. Matter Management covers intake, triage and a Matter Dashboard. LegalOn says Vault "isn't just another repository" and positions it against multi-quarter CLM implementations rather than as a CLM. |
| Pricing | Starter is $400 a month, or $2,400 a year, for one seat. Team is custom-priced for two or more seats. Every plan includes every feature and unlimited use. | Quote-based. Three plans are listed: Core Review, Contracting Suite (includes Vault) and Productivity Suite (adds intake and triage agents and a matter dashboard), with add-ons and view-only licenses for business users. Book a demo. |
| Free trial | Yes. 7 days with every feature, no credit card required. | LegalOn's July 2026 announcement says prospects "can request a demo or free trial." |
| Security claims(as listed on each vendor's site) | Customer data is never used to train AI models, and AI providers keep request logs only for abuse monitoring, for up to 30 days. Data is hosted in the US on AWS and encrypted in transit (TLS 1.3) and at rest, with private file uploads and single sign-on (SSO). See goheather.io/security. | SOC 2 Type II, ISO/IEC 27001:2022 and ISO/IEC 27017:2015 listed, with GDPR and CCPA compliance. No customer data used to train models and none retained by the AI provider. Encrypted at rest and in transit, hosted on AWS and Google Cloud, with US, EU (Germany) and Singapore data residency options since April 2026, and annual penetration testing. |
| Built for | Business teams that handle contracts and everyday legal work, such as sales, procurement, HR and finance, plus in-house counsel and law firms. Everything a legal team does except litigation, from one user to enterprise teams on a custom agreement. | In-house legal, legal operations, procurement, contract management, sales and law firms. |

How goHeather and LegalOn differ
Who it is built for
LegalOn is built for in-house legal, legal operations, procurement, contract management, sales and law firms, with attorney-built playbooks at its core. goHeather is designed to be used by non-lawyers and lawyers alike: the business teams that handle contracts every day, and the general counsel who work with them.
Where the playbook comes from
LegalOn's distinctive offer is a library that exists on day one, written by its attorneys for common contract types and jurisdictions, which you can customize or supplement with your own, converted from templates, guidelines or prior redlines. goHeather starts from your standard: generate a playbook from a contract you already use in about a minute, build one by hand or start from a sample, then edit it in plain language. Both let a rule hold a preferred position and fallbacks; goHeather also records the deviations you never accept and guidance notes, and turns any finding into a new rule in one click.
What surrounds review
LegalOn offers an Assistant with 100+ attorney-built prompt workflows, intake, triage, a Matter Dashboard, named agents for each of those jobs, translation in 30 or more languages, optional entity and board management, and a vault that extracts dates and sends renewal notifications. goHeather puts drafting, editing, review and contract tracking in one workspace: whole agreements drafted from a description, tracked changes with an explanation beside each edit, a contract list with extracted dates and obligation tracking, and e-signature, with the Vault and email intake in beta.
Drafting
goHeather drafts a whole agreement from a description: it asks a few questions, has you approve an outline, drafts each section and leaves anything you didn't supply as a labeled blank. LegalOn's Drafting Agent drafts and edits directly in Word, and LegalOn ships 100+ market-standard templates.
Model choice
goHeather lets you choose between six current models from OpenAI, Anthropic and Meta in each chat, with unlimited use on every plan. LegalOn says it evaluates each major model release and deploys the best models for each use case, and its AI team publishes contract review benchmarks.
Pricing and trial
goHeather publishes its price, $400 a month for Starter with every feature, and offers a 7-day free trial. LegalOn's pricing is quote-based, with a demo or free trial on request.
What business teams say about goHeather
“Easy to use, quick, credible and efficient!”
Andrea Anders Inc. “Cool stuff, I like the comments I’m getting. It’s super helpful.”
MattHealthcare Technology Entrepreneur “I enjoyed using the platform, I will certainly use it again when I have other leases to review.”
Carlos DeOliveiraPresident & CEO, Wine & Spirits Retail Marketing Inc.
goHeather or LegalOn: which fits your team?
When LegalOn is the better fit
You want a ready-made playbook for a common contract type or one of 23 foreign jurisdictions on day one and will adapt it. You need contracts translated as part of review, or data residency in the EU or Singapore. You want intake, triage and a Matter Dashboard in the same tool as review, with agents handling the routine parts. You want a vault that extracts dates and emails you before renewals.
When goHeather is the better fit
Your contracts are handled by people who aren't lawyers, such as sales, procurement, HR and finance teams, or by a general counsel working with them. Every finding and every edit comes with a plain-English explanation, so anyone on the team can act on it. You want to start from your own positions rather than a library playbook, generated from your own contracts and sharpened by every review. You draft whole agreements as often as you review them. You want to pick the AI model, see a published price, or start a free trial today.
