As a commercial lawyer, I saw many deals that did not justify spending thousands of dollars on legal review. I wish goHeather’s AI contract review had existed back then.”

Spot Issues And See Insights

goHeather contract review AI ranks what it finds by severity: High, Medium or Low. Every finding cites the clause and the page, quotes the wording, and explains the risk in plain English. You set your side of the deal and the governing law before the review starts, so the findings are written for your position. Choose how deep it goes, from deal-breakers only to every clause, and add a playbook to check the contract against your own standards.

Examples of real insights from goHeather

AI InsightRisk Level: High

This indemnity runs one way and covers any claim connected to the agreement, including claims caused by the vendor's own conduct. Consider making it mutual and limiting it to claims caused by the customer's breach or negligence.

Quote from contract

“Customer shall indemnify, defend and hold harmless Vendor from any and all claims arising out of or relating to this Agreement.”

AI InsightRisk Level: High

The renewal is automatic, and the notice window closes 90 days before the term ends, which is easy to miss. Consider a shorter notice period, a reminder from the vendor before the window closes, or a right to terminate for convenience after the first term.

Quote from contract

“This Agreement shall automatically renew for successive one-year terms unless either party gives written notice of non-renewal at least ninety (90) days before the end of the then-current term.”

ChatGPT, Claude and Gemini vs goHeather

ChatGPT, Claude and Gemini are good at reading a contract, explaining a clause and drafting new wording, and goHeather runs on the same kind of models. What a chatbot can't give you is someone standing behind the result: no lawyer-made playbook, no lawyer to check the output, no tracked changes in your document. So you are left to act on it alone. goHeather adds the lawyers and the workflow. Here is how we compare:

Nobody stands behind the output: you act on it alone
Lawyer-built guardrails and lawyer-made playbooks, and a lawyer reviews your output when you ask
Doesn’t confirm which side of the contract you are on or applicable jurisdiction
Confirms what side of the contract you are on and which jurisdiction's law applies

Tell them what you will not accept

Mark the findings you will not accept and goHeather writes the letter to the other side: one entry per term, the clause as it reads today next to the wording you propose, and an editable position for each. Export it as Word or PDF, or open it in your email. When their version comes back, compare the two and see exactly what changed.

    Built from your review

    Choose which flagged terms go in. The letter numbers them in order.

Review Depth

Pick one of four levels before each review: Existential flags only deal-breaking risks, Issues adds what is worth redlining, Warnings adds non-standard clauses, and Everything goes clause by clause.

Review Redlines Only
