Getting started

What RealSiteWorth is

You give it a domain, a website URL, or a social handle. It gives you back a conservative value range and a confidence score.

Not a single number. From the published methodology:

Real Site Worth publishes an automated value range with a confidence score. We avoid single-number precision because websites, domains, and creator assets trade in markets with uncertainty, negotiation, and incomplete public data.

The range is deliberately cautious. Where inputs disagree, the public estimate leans low:

We intentionally avoid inflated values. Where model inputs or comps point in different directions, the public estimate leans conservative. A conservative estimate is still imperfect, but it is more useful than a promotional number that cannot survive diligence.

What it is not

This matters more than the feature list. The disclaimer is explicit:

Every value range on Real Site Worth is an automated estimate. It is not a certified appraisal, broker opinion of value, fairness opinion, securities analysis, tax opinion, legal opinion, investment advice, lending decision, insurance valuation, or guarantee of any sale price.

Using the product creates no professional relationship. No attorney-client, no advisor-client, no broker-client, no appraisal relationship.

The methodology page frames the intended use directly: a conservative starting point for diligence, not a certified appraisal, broker opinion, investment recommendation, tax opinion, or legal conclusion.

A report cannot replace verified revenue records, analytics access, contract review, account-transfer review, tax analysis, broker diligence, or buyer-specific negotiation. Verify independently before any transaction that matters.

Every surface that displays a value carries a standing notice: the value range is an automated estimate, and the Memo and Roadmap explain the estimate after it exists rather than generating the number.

Run your first valuation

The fastest path costs nothing and needs no account.

1. Go to the homepage.
2. Paste a website URL or a bare domain.
3. Read the range and the confidence score.

Anonymous limit: 3 valuations per day. The counter runs on a UTC calendar day and is enforced against two subjects at once, your IP address and a browser cookie. Clearing cookies still hits the IP bucket. Rotating IPs still hits the cookie bucket. There is also a burst guard of 8 requests per IP per minute.

When you hit the wall you get a plain message, not an error page: anonymous use is capped at 3 valuations per day, with a prompt to create a free account.

One thing to know up front: free runs are teaser runs. You get the range, the confidence score, and the asset classification. Confidence on a free run is capped at LOW / 35% no matter how strong the underlying signals are, and the written Valuation Memo and Value-Gap Roadmap are not generated. Report exports from a free account carry a TEASER watermark.

What an account adds

Sign-in is passwordless. You enter an email address and get a sign-in link. No password, no credit card.

A free signed-in account raises the allowances:

Website valuations move from a daily bucket to a monthly one. Social surfaces stay on a daily bucket. The monthly allowance resets at the start of the next UTC calendar month.

A free account is still the teaser tier. It raises volume and saves your history. It does not unlock the Memo, the Roadmap, or a watermark-free export.

Note on sign-in availability. Sign-in sits behind a server-side launch flag that defaults to closed. The flag is checked before anything else on a sign-in-link request, so while it is closed it blocks every request for a link — existing account holders as well as new sign-ups. You see this instead of an error:

Account sign-up isn’t open yet. RealSiteWorth is free to use without an account.

The anonymous path always works regardless.

What a paid plan adds

Paid runs are not teaser runs. That is the real difference:

• The full AI Valuation Memo and Value-Gap Roadmap are generated.
• Confidence is not capped at 35%.
• Report export drops the TEASER watermark.
• Watchlist goes to 10 slots on Basic and 50 on Pro.
• Pro adds CSV export and Domain vs. Business mode (MRR/SDE).
• Pro includes MCP and agent access over Bearer auth, rate limited to 5 requests per second, metered against the same Pro monthly quota.
• Basic's 10 advanced valuations per month are included in the plan, and the in-app way to run them is rolling out. Today advanced runs enter only through the agent/API transports, and MCP/agent access is Pro-only, so there is no dashboard button that spends them on Basic yet.

Programmatic access

Pro includes an MCP endpoint with four methods: value_website, value_social, get_watchlist, and get_history.

Tool discovery needs no auth:

curl https://realsiteworth.com/api/mcp

Point an MCP client at it with a Pro key:

{
  "mcpServers": {
    "realsiteworth": {
      "url": "https://realsiteworth.com/api/mcp",
      "headers": { "Authorization": "Bearer rsw_<your-pro-key>" }
    }
  }
}

How the estimate is produced

The order matters, and it is the single most important thing to understand about the product.

1. Classify the asset. A model reads the sanitized text of the homepage and returns structured labels only: category, operating site vs. aged domain vs. bare domain, name type, pronounceability, keyword tier. Text from the page is wrapped in explicit untrusted-data delimiters, and the classifier is instructed to treat it as data rather than instructions.
2. Assemble signals. Domain age, traffic, traffic concentration, referring domains, rank, archive history, and similar public signals. Signals that are missing stay missing. They are recorded as omitted rather than filled with a guess, and missing data lowers confidence.
3. Compute the number. A deterministic function takes the signals and produces the range (low, mid, high), the confidence label and percentage, and the multiple. No model is involved in this step.
4. Explain the number. Only after step 3 does AI write the Valuation Memo and the Value-Gap Roadmap, and only on paid runs.

The constraint given to the model at that fourth step is explicit in the prompt:

CRITICAL RULE: Every dollar figure, percentage, score, and multiple in the data below was computed by RealSiteWorth's deterministic valuation engine. You must NOT invent, change, recompute, or contradict any number. Use ONLY the numbers given. Do not state facts you cannot derive from the supplied data (e.g. never claim a past sale price). Write analysis, not arithmetic.

Currency tokens are stripped from AI-written impact strings before display, so the model cannot smuggle a number back in through prose.

If the memo or roadmap call fails, the report still ships with the computed number and empty narrative sections. The number never depends on the model being available.

What is and is not sent to AI providers

Sent:

• The submitted domain or handle.
• Text extracted from the target's homepage, after sanitization.
• Numbers the deterministic engine already computed, for narration.

Sanitization is not a policy statement, it is code that runs at the model boundary. Before homepage text reaches a provider it is stripped of script, style, comment, and hidden blocks, then email addresses become [email], phone numbers become [phone], and IPv4 and IPv6 addresses become [ip]. The result is truncated to 20,000 characters.

Not sent: your email address, your name, payment details, account identity, your IP address, or support messages. The privacy policy states this as a commitment, and the sanitizer enforces the free-text half of it in code.

If you send a support request containing personal information, it is handled in the support workflow and not fed into a report prompt.

Where to go next

• Valuation surfaces. Which asset types are supported and what each one needs as input.
• Plans and quotas. Every limit, which bucket it uses, and when it resets.
• Reading your report. What the range, the confidence score, and the Roadmap lifts actually mean.
• Dashboard. Saved reports, watchlist, and report export.
• MCP and agent access. The Pro programmatic surface, method by method.
