Nothing in these docs grants a license to copy the product. ## Common questions **Does rei.OS work with ChatGPT and Claude?** Yes. AI Connect is rei.OS's MCP server. Connect Claude or ChatGPT and it reads your live pipeline, properties, budgets, scope, comps, contacts, deal analyses and activity. When it writes, it drafts first and you approve. AI Connect is included in the $99 plan. **How is rei.OS different from FlipperForce?** FlipperForce is a rehab estimator and scheduler. rei.OS runs the whole deal: comps and underwriting, an AI-drafted scope of work from a walkthrough or photos, the schedule and budget, books and rentals, plus AI Connect so your own assistant can work in it. One price for the whole team instead of per seat. **How is rei.OS different from REsimpli?** REsimpli is a sales CRM for wholesalers with a strong dialer and SMS stack. rei.OS starts where the contract does: underwriting, scope, construction management and accounting, with AI across every step. If your bottleneck is outbound calling, REsimpli is the better fit. If it is running the deal after you find it, rei.OS is. **Where do the comps and bank data come from?** Property, owner and comp data come from rei.OS Data, powered by BatchData, so Auto-enrich fills a property card from an address and the Comps Engine pulls real sold comps. Bank and credit card transactions come in through Plaid; you sign in to your bank inside Plaid's window and rei.OS never sees your credentials. **How much does rei.OS cost?** $99 a month for your whole team, unlimited properties, no per-seat pricing. Thirty days free with no card. Subscribe before January 1, 2027 and the rate is locked for life; it is $129 after. **Who is rei.OS for?** Fix-and-flip investors, wholesalers who also rehab, and BRRRR or buy-and-hold investors who manage their own projects. It was built by an active Ohio flipper for his own deals first. **What does rei.OS not do?** It has no dialer and no marketing lists. Bring your own lists from PropStream, DealMachine or your county; rei.OS enriches and runs the deal from there. The full list of what is still coming is on the roadmap. ## Getting started - [Sign up, free trial and your first property](https://reiosapp.com/docs/getting-started): From no account to your first property - [Billing and the $99 Founding rate](https://reiosapp.com/docs/billing): One plan, $99 a month, locked for life - [Team members, settings and profile](https://reiosapp.com/docs/team-and-settings): Invite your team and manage your account ## Underwrite - [Add a property](https://reiosapp.com/docs/add-property): Add a lead or owned property fast - [Deal Pipeline](https://reiosapp.com/docs/deal-pipeline): Every deal from lead to sold - [Comps Engine](https://reiosapp.com/docs/comps): Find, save and appraise sold comps - [Deal Analyzer](https://reiosapp.com/docs/deal-analyzer): Underwrite a deal step by step - [Deal Snapshot](https://reiosapp.com/docs/deal-snapshot): Share a deal as a link and PDF ## Scope - [Walkthrough Mode](https://reiosapp.com/docs/walkthrough-mode): Narrate a property walk, get a report - [Photo Studio](https://reiosapp.com/docs/photo-studio): Scope and render from one photo - [Scope of Work Builder](https://reiosapp.com/docs/scope-of-work): Build, price and lock your rehab budget ## Build - [Project Gantt](https://reiosapp.com/docs/project-gantt): Turn your scope into a dated schedule - [Budget vs Actuals](https://reiosapp.com/docs/budget-vs-actuals): Catch rehab overruns by category early - [Property Portal](https://reiosapp.com/docs/property-portal): One QR code per property for uploads - [Professionals directory](https://reiosapp.com/docs/professionals): Your contact book for every deal ## Books - [Bank Feed](https://reiosapp.com/docs/bank-feed): Categorize every bank and card transaction - [CSV and Google Sheets import](https://reiosapp.com/docs/csv-import): Fill missing months from your bank's export - [Reports](https://reiosapp.com/docs/reports): Your reporting rhythm, plus on-demand reports ## Workspace - [Tasks and Calendar](https://reiosapp.com/docs/tasks-calendar): Your to-dos and schedule in one place - [Daily Digest](https://reiosapp.com/docs/daily-digest): One morning email with today's tasks - [Templates, QR Studio and business cards](https://reiosapp.com/docs/templates-qr): Brand your exports, cards and QR codes ## AI - [rei.AI assistant](https://reiosapp.com/docs/rei-ai): Ask questions or co-work through tasks - [Ella, your AI executive assistant](https://reiosapp.com/docs/ella): Automatic check-ins on your active projects - [AI Connect](https://reiosapp.com/docs/ai-connect): Use Claude or ChatGPT with your data ## Reference - [What rei.OS does not do yet](https://reiosapp.com/docs/not-yet): Straight answers on what is still coming - [Glossary](https://reiosapp.com/docs/glossary): The terms you meet in rei.OS ## Comparisons - [Best AI software for real estate investors (2026)](https://reiosapp.com/compare/best-ai-real-estate-investor-software): Seven tools, sorted by what their AI actually does: runs the deal, finds the deal, makes the calls, or crunches one number - [CompanyCam vs rei.OS](https://reiosapp.com/compare/companycam): A jobsite photo app for contractors versus photos that turn into the scope, schedule and books - [DealCheck vs rei.OS](https://reiosapp.com/compare/dealcheck): A $20 deal calculator versus the AI operating system that runs the deal after the math - [DealMachine vs rei.OS](https://reiosapp.com/compare/dealmachine): Driving for dollars, owner data and mail versus the AI operating system for the deal you found - [FlipMantis vs rei.OS](https://reiosapp.com/compare/flipmantis): AI voice agents and lead scoring versus AI scope, underwriting, construction and books - [FlipperForce vs rei.OS](https://reiosapp.com/compare/flipperforce): A rehab estimator and scheduler versus an AI operating system that runs the whole deal - [PropStream vs rei.OS](https://reiosapp.com/compare/propstream): Nationwide data with predictive scoring versus the AI operating system for underwriting, scope, construction and books - [REsimpli vs rei.OS](https://reiosapp.com/compare/resimpli): A wholesaler's sales CRM with a dialer versus an AI operating system for underwriting, scope, construction and books ## More - [All docs in one file](https://reiosapp.com/llms-full.txt) - [Feature Roadmap](https://reiosapp.com/roadmap): what is shipped, coming soon, or on the backlog - [Policies](https://reiosapp.com/policies)
