What is it?

Freelancers and small business owners accept unfavorable contracts because they lack legal review resources. They read boilerplate and miss critical issues: payment holdback clauses, non-compete language, liability caps, IP ownership gaps. TermsGuard solves this by parsing contracts via Claude, flagging specific high-risk clauses, explaining them in plain English, and suggesting negotiation language for common scenarios. A freelancer pastes a client SLA; TermsGuard identifies a 30-day payment term as 'above market (typical 7–14 days for your industry)' and suggests counter-language. This is not legal advice (disclaimer is clear), but a decision-support tool. It converts risky situations from 'unknown unknowns' to 'known unknowns.' The business model: freemium (1 analysis/month) → Pro ($19/month, 20 analyses/month) → Teams ($79/month). Why 100% buildable right now: Claude's function calling works great for clause extraction, prompt engineering can tune risk scoring per industry, and no training or custom models needed.

Why now?

Freelancer economy has exploded (50M+ freelancers globally). Contract disputes are rising (Better Business Bureau reports 15% increase in 2024–2025). Claude's function calling is now stable for structured extraction. This is a 2026 pain point waiting for a tool.

▸Paste-in contract analysis (PDF or text)
▸AI clause extraction and categorization
▸Plain-English risk summaries
▸Industry-specific risk scoring
▸Negotiation suggestions with counter-language templates
▸Comparison to market standards (e.g., 'payment terms 30 days above market')
▸Downloadable risk report

Target Audience

Freelancers (5M in US), agencies, and bootstrapped startups (2–20 people). 40% face contract reviews monthly. TAM: ~2M people willing to pay $19/month for risk screening.

Example Use Case

Jordan, a freelance designer, receives a 40-page brand design contract with a 6-month non-compete. She pastes it into TermsGuard. Claude flags: (1) non-compete is 'high risk — unusual for design work in US,' (2) payment term is 50% upfront + 50% on delivery (standard), (3) IP ownership clause: 'client retains all IP — typical, but consider negotiating mockups.' Jordan pushes back on the non-compete and gets it removed. She pays $19/month for that one negotiation win.

User Stories

▸As a freelancer, I want to paste a contract and get instant red flags before negotiating, so that I don't miss unfavorable clauses.
▸As a small business owner, I want plain-English explanations of legal jargon, so that I understand what I'm signing.
▸As a contractor, I want to know if contract terms are above or below market for my industry, so that I can negotiate from data.

Acceptance Criteria

Contract Analysis: done when 10 real contracts are analyzed and top 3 risks match manual lawyer review 90% of time. Clause Extraction: done when all major contract sections are identified correctly. Explanations: done when non-lawyers understand flag explanations (test with 5 users). Risk Scoring: done when high-risk flags are differentiated from low-risk. PDF Export: done when downloadable report is formatted correctly.

Is it worth building?

$19/month × 400 Pro users = $7,600 MRR. $79/month × 50 Team users = $3,950 MRR. Total: $11,550 MRR at month 4.

Unit Economics

CAC: $50 via organic (ProductHunt + Twitter). LTV: $19/month × 12 months = $228 (conservative, many users cancel after 1 year). Payback: 2.6 months. Gross margin: 90% (API costs < $2/month per user at tier 1).

Business Model

Freemium SaaS subscription

Monetization Path

Free: 1 contract/month, 500 word limit. Pro: $19/month, 20 contracts/month, full-length. Teams: $79/month, team seats + API access.

Revenue Timeline

First dollar: week 2 (freemium trial). $1k MRR: month 2 (100 Pro subs). $5k MRR: month 4. $10k MRR: month 7.

Estimated Monthly Cost

Claude API: $100 (token usage for analysis), Vercel: $20, Supabase: $25, Stripe: $30 (payment processing), monitoring: $10. Total: ~$185/month at launch.

Profit Potential

Full-time at $8k–$18k MRR. High margin.

Scalability

High — can add video explanation, industry-specific templates, integration with signature tools.

Success Metrics

Week 1: 500 signups. Month 1: 50 paid conversions. Month 3: 300 active Pro users. Retention: 75%+ monthly (high for free-to-paid).

Launch & Validation Plan

Interview 20 freelancers about their contract pain. Build landing page with 3 contract analysis examples. Recruit 30 beta users from freelancer communities. Survey them on risk accuracy and usefulness. Iterate on prompt.

Customer Acquisition Strategy

First customer: Post on Twitter/Reddit about a contract analysis example (famous bad clause). DM 20 freelancers on Upwork offering free first analysis. Then: ProductHunt, Freelancer communities (r/freelance, FreeUP, Upwork forums), Twitter #freelance, sponsorship of freelancer newsletters.

What's the roadmap?

Feature Roadmap

V1 (launch): contract paste/upload, Claude analysis, risk flags, plain-English summaries, PDF export. V2 (month 2-3): industry-specific scoring (e.g., 'tech', 'design', 'consulting'), comparison to market standards, negotiation templates. V3 (month 4+): real-time editing with AI suggestions, Slack bot integration, client negotiation tracking.

Milestone Plan

Phase 1 (Week 1-2): Claude analysis endpoint, test on 20 real contracts. Done when top 3 risks match manual review. Phase 2 (Week 3-4): UI, Stripe billing, PDF export. Done when 10 beta users can complete full workflow. Phase 3 (Month 2): Legal disclaimers, privacy policy, launch.

How do you build it?

Tech Stack

Next.js, Claude API (with function calling), Stripe, Supabase — build with Lovable for forms, Cursor for Claude integration.

Time to Ship

2 weeks

Required Skills

Claude API, Stripe, basic Next.js.

Resources

Claude docs, Stripe docs, contract law blogs for prompt tuning.

MVP Scope

1. Next.js form for contract paste/upload. 2. Claude API integration with contract analysis prompt. 3. Risk summary + flag extraction. 4. Clause-by-clause explainer. 5. Negotiation suggestions UI. 6. Stripe billing (free/Pro tiers). 7. Download PDF report. 8. Legal disclaimer modal.

Core User Journey

Architecture Pattern

User pastes contract text -> Claude function calling extracts clauses -> risk scoring + explanation generation -> Postgres stores analysis -> user downloads PDF.

Data Model

User has many Analyses. Analysis has many Flags. Flag has risk level, clause text, explanation, and negotiation suggestion.

Integration Points

Claude API for analysis, Stripe for payments, Supabase for storage, Vercel for hosting, Resend for email (optional).

V1 Scope Boundaries

V1 excludes: legal advisor chat, document generation, signature integration, multi-jurisdiction comparison, batch analysis.

Success Definition

A freelancer finds the product via ProductHunt, analyzes a real contract, acts on 1 risk flag (e.g., negotiates a clause), and subscribes to Pro without outreach.

Challenges

Ensuring Claude doesn't hallucinate legal advice (must be clear about disclaimers). Tuning risk scoring per industry (contracts differ wildly across fields). Churn from users only needing 1–2 analyses per year.

Avoid These Pitfalls

Do not claim to be legal advice (use disclaimers heavily). Do not promise 100% accuracy (AI can miss edge cases). Do not build AI that generates legal language — stick to summaries and suggestions. Do not oversell to small biz that truly need a lawyer (focus on 'first-pass screening').

Security Requirements

Auth: Supabase Auth + Google OAuth. RLS: analyses visible only to owner. Input validation: contract size max 5MB, text sanitization. Rate limiting: 20 analyses/day per free user. GDPR: auto-delete analyses after 90 days (user-configurable), no third-party sharing.

Infrastructure Plan

Hosting: Vercel (frontend + API). Database: Supabase (PostgreSQL). File storage: Supabase Storage for PDFs (optional). CI/CD: GitHub Actions. Monitoring: Sentry for errors. Cost breakdown: Vercel $20, Supabase $25, Stripe fees $30, monitoring $10.

Performance Targets

Expected DAU: 50, API calls/day: 500. Analysis latency: under 60s per contract. Page load: under 2s. API response: under 3s for Claude analysis (async).
