Mastersheets.ai
Mastersheets.ai turns a single master spreadsheet into a permissioned business system: each role sees only its own filtered view, AI generates the structure from a plain description, and every change is recorded in a full audit trail.
What is Mastersheets.ai?
Mastersheets.ai is a web-based spreadsheet platform that adds role-based permissions, approval workflows and audit logging to an interface most teams already know. Its own terms of service describe it as a SaaS platform for building structured, no-code ERP systems powered by spreadsheet logic and AI automation, and it is positioned as the middle ground between a spreadsheet a team has outgrown and a full enterprise system too rigid or too costly to adopt.
The central idea is a single master sheet acting as the source of truth. Rather than copying files for each department, administrators create filtered views: data can be restricted by row, by column or by value according to a user's role, so sales sees prospects while HR sees salaries and neither sees the other. Any authorised change propagates instantly to every view, removing the version conflicts that duplicated files create.
AI intervenes mainly at setup. Describing a requirement in plain English — the publisher's own example is a sales CRM with columns for lead name, deal size, stage and expected close date — produces a structured sheet with the matching columns and data types. Each plan carries a monthly allowance of AI credits, from 50 on the free tier to 5,000 on the most expensive one.
Around this sit validation rules (imposed data types, dropdown lists, numeric ranges, required fields), automated approval chains with real-time status, deadline reminders and escalations, and a complete audit trail. Existing data arrives from CSV or Excel files and can be exported at any time.
Documented use cases cover order tracking, inventory and supplier data for operations teams; financial models, KPI dashboards and departmental budgets for leadership; multi-stakeholder project trackers; and department-level tools such as sales pipelines, campaign trackers and HR onboarding checklists. Capacity is bounded: plans run from 4 to 50 users and from 2,000 to 1,000,000 cells. The product is web-only, with no public API and no mobile application, and its interface is English only. It is published by Kloud Komputing Software Systems Pvt. Ltd., an Indian company.

Data, GDPR & hosting
A consolidated view of how Mastersheets.ai handles your data.
GDPR overview
GDPR compliance is claimed explicitly in the terms of service, alongside India's Digital Personal Data Protection Act, and the implementation is more concrete than most tools of this size: a standalone Data Processing Agreement is published, data subject rights are enumerated twice (access, rectification, erasure, portability, objection, restriction, withdrawal of consent), international transfers are covered by standard contractual clauses, breach notification to the controller is promised without undue delay, and customers hold audit rights over processing activities. Dedicated addresses exist for privacy and DPA questions. Two gaps stand out: no EU representative is designated under Article 27 even though the publisher is established in India, and no data protection officer is named. No subprocessor is listed by name and no hosting country is disclosed.
Who owns the data?
Customers keep ownership of everything they upload or generate; the publisher explicitly disclaims any claim over customer content, including templates and configurations. In exchange, users grant Kloud Komputing Software Systems Pvt. Ltd. a worldwide, non-exclusive, royalty-free licence to use, store, display, reproduce, modify and distribute that content, limited to providing, maintaining and improving the service. Users warrant they hold the rights needed to grant it. Contractually the publisher acts as data processor and the customer as data controller. The platform itself, its software, design and brand remain the publisher's exclusive property, and any feedback submitted may be reused without compensation.
Reuse rights
Customers may reuse their own data freely: ownership stays with them, exports to CSV or Excel are offered at any time, and the privacy policy lists data portability among the rights available on request. No permission needs to be sought to extract or reuse content the customer put in. On the publisher's side, data is used to run and maintain the service, process transactions, send notifications, improve the platform, detect fraud and meet legal obligations. Anonymised data may be analysed internally to develop new features. Selling, renting or sharing data for marketing purposes requires explicit consent. Sharing is otherwise limited to service providers, legal authorities on lawful request, and third parties the customer has consented to. Nothing anywhere on the site addresses whether customer data is used to train AI models, nor offers any way to opt out.
Data retention & training
Hosting summary
No hosting country or region is published. The privacy policy refers only to secure data centres with 24/7 monitoring, and targeted searches across both the extracted text and the archived HTML found no mention of any provider, country or region. Security measures are described in more detail: end-to-end encryption in transit, AES-256 encryption at rest, TLS 1.2 or above, regular security audits and penetration testing, access controls and authentication. International transfers are anticipated and covered by standard contractual clauses and data processing agreements. Backups follow a documented schedule of real-time replication, daily full backups and weekly archives with a 30-day retention period. The publisher is established in India, the governing law is Indian and arbitration takes place in New Delhi, which is the only jurisdictional anchor the documents provide. As a purely technical observation, the domain resolves to an address geolocated in the United States, but this is an infrastructure measurement rather than a statement by the publisher and should not be read as a hosting commitment.
Things to keep in mind
Risks and trade-offs to weigh before adopting Mastersheets.ai.
- Both demo routes published on the site return 404, including the booking link also used as the contact link on every main page
- The only real contact page is linked from no menu and absent from the sitemap; the address it publishes is personal and on a third-party domain
- Nothing is said about whether customer data is used to train AI models, and no opt-out is documented — a real concern for HR and finance data
- No hosting country is disclosed and no subprocessor is named, which makes data location impossible to verify or contract on
- Homepage testimonials use stock photography and unverifiable names, and the productivity figures on comparison pages are unsourced
- Concentrating a whole department's data in one master sheet creates a single point of failure: permissions misconfigured once expose everything at once
- The convenience of an audit trail on every change also makes the tool a fine-grained surveillance instrument over colleagues' work
Setup & Integrations
Technical difficulty
Low. Nothing is installed: an account is opened online, with no credit card for the free plan, and sign-in works by email or Google account. No code is required — the sheet structure is generated by AI from a description written in plain English, and existing data is imported from CSV or Excel. The real skill needed is not technical but organisational: modelling roles properly and writing validation rules that match the process. The publisher claims a working system in minutes rather than months. Note that with no API or webhooks, there is nothing to integrate but also nothing to automate outside the tool.

Should you pick Mastersheets.ai?
Mastersheets.ai answers a real and well-identified problem: the point where a shared spreadsheet stops being enough because everyone can edit everything, nobody can see who changed what, and approvals are chased by email. Its response — one master sheet, filtered views per role, validation rules, approval chains and a full audit trail, with AI generating the structure from a plain description — is coherent and clearly documented across the product pages.
Two things stand out favourably. The contractual apparatus is unusually complete for this price bracket: terms of service, privacy policy, a standalone Data Processing Agreement and a Service Level Agreement are all published and readable, with a quantified 99.9% availability commitment and contractual support response times. And the permanent free plan makes evaluation genuinely risk-free.
Against this, the product is young and shows it. There is no public API, no mobile application, and a hard ceiling of fifty users. No hosting country is disclosed, no subprocessor is named, no security certification is claimed, and no EU representative is designated despite an Indian publisher claiming GDPR compliance. The complete silence on whether customer data trains AI models deserves a direct question before committing HR or financial data.
Editorial care is uneven too: both demo links published on the site return errors, the only real contact page is reachable from no menu, homepage testimonials are illustrated with stock photography, and several figures in the SLA template were left blank. None of this affects the working product, which responds normally, but it does set expectations about the maturity of the company behind it. Worth a trial on the free plan for a team of under fifty; worth direct questions before anything sensitive.
