Lexarith

Revenue intelligence for agencies, contractors, and service businesses.

Lexarith is an AI-powered Gmail extension built exclusively for service-based business owners who bill clients for their time — freelancers, agencies, contractors, consultants, coaches, lawyers, accountants, architects, photographers, developers, and marketing professionals. Every month, service businesses lose between $2,000 and $8,000 to scope creep — clients quietly adding work, requesting revisions beyond what was agreed, and asking for extras disguised as small favors. Most business owners never notice it happening until the project is over and the profit is gone. Lexarith sits silently inside your Gmail sidebar and catches scope creep in real time, before you respond. HOW IT WORKS When you open a client email in Gmail, Lexarith instantly analyzes the message using Claude AI — one of the most advanced AI models in the world. It compares the email content against your saved contracts and your business profile to detect unauthorized requests, risky language, and hidden revenue threats. The entire analysis takes under 3 seconds. THREE POWERFUL SCAN MODES Scope Guard — The core detection mode. Scans every client email for deliverables that fall outside your agreed contract scope. Flags risky phrases, estimates the dollar value of the out-of-scope request, and generates a professional response you can send in one click. Compliance Check — Compares email content directly against your uploaded contracts and SOW documents. Identifies when a client is requesting something that contradicts your written agreement, backed by your actual contract language. Profit Leak Detector — Deep analysis mode that identifies favor language, unpaid time requests, and patterns of scope expansion. Surfaces revenue leaks before they become habits. KEY FEATURES Real-Time Email Analysis — Lexarith analyzes client emails the moment you open them. No manual copying and pasting. No switching between apps. The analysis appears instantly in the sidebar while you read the email. Dollar Value Estimates — Every detected risk comes with an estimated dollar value so you can see exactly how much revenue is at stake before you respond. AI Response Generator — When scope creep is detected, Lexarith generates a professional, firm but friendly email response that acknowledges the client's request and presents a clear path forward. Review it, edit if needed, and send with one click directly from Gmail. Change Order Generator — Automatically drafts a formal change order document when out-of-scope work is requested. Professional language that protects your position and gets you paid for extra work. Invoice Generator — Create and send professional invoices directly from the Lexarith sidebar without leaving Gmail. Contract Vault — Upload and store your client contracts, proposals, and SOW documents directly in Lexarith. The AI references your agreements on every scan for hyper-accurate, contract-aware detection. Scan History — A complete log of every scan performed, with verdicts, risk scores, flagged phrases, and dollar values. Export your history as CSV for record keeping or dispute resolution. Action Queue — A prioritized list of all flagged emails requiring your attention, sorted by risk level. Respond to clients, generate change orders, and close revenue leaks from one organized view. Team Collaboration — Business and Agency plan users can invite team members, share the contract vault, and leave sticky notes on flagged items so the whole team stays aligned on revenue protection. Weekly Summary Reports — A weekly digest of all scans performed, revenue protected, and risks detected, delivered automatically to help you track your protection over time. PERSONALIZED AI ANALYSIS During signup, Lexarith collects information about your business — your industry, services, charging model, client type, and whether you use contracts. This profile is sent to the AI on every scan so the analysis is specific to your business. A construction contractor gets completely different analysis than a web designer, even for the same email. PRIVACY AND SECURITY Lexarith is built with a privacy-first architecture. Email content is analyzed and immediately deleted — it is never stored on our servers. Your scan history, contracts, and business profile are stored locally on your own device using Chrome's built-in storage. All data in transit is protected by TLS 1.3 encryption. Our backend runs on Google Cloud Platform — the same infrastructure as Gmail itself. Your clients never know Lexarith exists. SUBSCRIPTION PLANS Starter — Free.
