How we research
and publish.

Who is responsible

Zahi Cohen publishes this site and develops Muchita Shopping under the Muchita AI name. Articles name Muchita AI as their organization author. Our comparisons explain our own product alongside other tools; they are publisher comparisons, with a commercial interest in our extension.

Muchita Shopping is free. We do not receive affiliate commissions or payment for retailer placement, and we do not sell placement in these guides. The guides link to our extension where it is relevant. We identify other products by name without implying their endorsement.

For a correction or a question about our sources, email support@muchita.ai. Include the page URL, the statement you are questioning and a source if you have one. Do not send payment details, passwords or personal shopping records.

What our sources establish

Calendar and shopping guides use linked organizer, retailer, public-authority and consumer-information sources. Each source has its own checked date. A date calculated from a calendar or standing rule is identified separately from an organizer’s announcement. An unannounced future sale or delivery deadline stays unconfirmed.

Competitor comparisons distinguish the other publisher’s statements from Muchita’s own product behavior. A feature described by a publisher is not a performance result we measured. Silence in a listing is not evidence that a product lacks a feature or follows a particular business model. Each comparison explains situations in which the other product may fit better.

Browser observations record what selected public product pages displayed at the stated time. They are not physical product tests, completed purchases or a survey of the entire market. We preserve unavailable variants, exclusions, contradictory page information and unresolved fields instead of treating them as successful comparisons.

How AI and translation are used

We use AI tools to assist research, drafting, translation, source review and page generation. Our publishing workflow also checks generated pages, links, language alternatives and required source dates. These checks can catch errors; they do not establish that every statement is correct.

AI-assisted review does not establish review by a qualified human expert or a native-language editor. Some translations share a source record; country guides can have separately maintained records and local primary sources. Check the country, source dates and scope on the page. A translated interface alone does not establish retailer coverage or the consumer rules for your purchase.

Where a page reports an original observation, its method and linked evidence take precedence over a generated summary. We label synthetic examples as examples. We do not generate retailer observations, expert credentials, user reviews or research results to fill missing evidence.

How we describe price evidence

A comparable offer needs the exact product and required variant, equivalent quantity or contents, identified seller, available stock, condition, comparable currency, tax basis, membership eligibility, purchase model and delivery market. With Local sellers only selected, a storefront naming another country remains visible. We feature its offer only with evidence that it delivers to the shopper's market. A monthly payment, trade-in benefit or a different bundle cannot substitute for an eligible full item price.

We compare normalized item prices only. Shipping stays separate as free, a stated charge, or unknown and may be added. It never changes the item-price order. A lower item price does not mean a lower checkout total, and a savings statement concerns the normalized item price.

An observed price is a dated snapshot. Two observations do not establish continuous price history, the lowest market price or a holiday discount. Missing evidence prevents a fully verified winning-deal claim.

Our price-comparison calculator works with offers you enter. Its eligibility checks are your confirmations; the calculator does not fetch retailers or independently verify prices. Use the same currency for all entered offers and convert amounts yourself before entry. Its fictional example is not a live deal.

Dates, corrections and limits

The page’s updated date describes its editorial revision. Source checked dates describe when those sources were inspected; they can be earlier than the page revision. A navigation or layout improvement does not mean every source was rechecked.

We revise an affected statement and its source checked date together when new evidence changes it. Original observations retain their earlier dates and remain distinguishable from later checks. A recent source date is not a guarantee that an offer, law or product has stayed unchanged.

A substantiated correction replaces the unsupported statement. A material change to a research conclusion should also explain what changed. Email reports help identify issues, but we cannot promise a response time or monitor every retailer continuously. Consumer-rule summaries are general information and do not determine the rights or tax treatment of an individual purchase.

Read the work and its limits

Our Sony headphone field note now retains one dated BUG observation and explains the unresolved stock and comparison limits. The other retailer rows and public download were withdrawn after source-terms review; they are not a public evidence set. The retained note does not establish a winning offer or current price.
