Loio
Pros
- + Aggressive pricing: Pro at $30/month month-to-month or $22/month billed yearly covers unlimited signing, 2,500+ templates and 10 AI summaries (loio.com/pricing, at time of writing)
- + Template breadth (2,500+ documents claimed) with interview-style customization beats editing raw DOCX for standard agreements
- + AI summary cleanly extracts parties, dates, key clauses and one-sided terms — good triage for non-lawyers in my testing
- + Honest free tier lets you complete one real task (one signed document, one AI summary per month) before paying
- + End-to-end small-business flow in one place: template, edit PDF, sign, request signatures
Cons
- - The Word add-in contract-review heritage is gone from the current product — no playbook review, no redlining, no clause risk scoring
- - AI summary quotas are small on every tier (max 10 uploaded-file summaries/month on Pro)
- - Trial of paid tiers caps signing at 3 signers per document, which limits realistic testing of routing flows
- - No repository, obligation tracking, or CRM/CLM integrations for legal-ops workflows
- - Small review footprint (G2 3.9/5 from 11 reviews) and a small parent company — support depth is limited
Harvey AI
Pros
- + Vault review workflow extracted clause data across a SaaS agreement set with page-level citations and caught a buried liability carve-out I nearly missed
- + Assistant handles ambiguous legal questions with jurisdictional clarification and explicit hedging instead of fluent overconfidence
- + Enterprise posture is serious: document-management integrations, audit trails, SSO and zero-retention options that pass firm security review
- + Proven at scale — used by more than half the Am Law 100 per Harvey's blog, with HEUKING expanding firm-wide after a two-year pilot
- + Workflow Agents compress first-pass multi-document review from hours to minutes while keeping an inspectable run history
Cons
- - No public pricing, no trial; third-party reports point to roughly $1,200/seat/month with 20-25 seat minimums — a six-figure annual floor
- - Not a citator; case-law validity checking still needs traditional research tools
- - Extraction output needed human correction on some cells in my test — supervision is mandatory, not optional
- - Multi-jurisdiction depth is uneven outside the US and UK and must be piloted, not assumed
- - Renewal risk at a vendor that raised $550M at a $15.5B valuation with growth expectations — negotiate price caps up front
