Data sources & disclaimer

1. Official data sources

Yasnify property reports draw on the following publicly available datasets:

2. How we use this data

Yasnify does not alter or manipulate source data. We aggregate, geocode, and compute summary statistics (incident counts, proximity calculations, year-over-year trends) to generate property reports. The methodology is documented on our How It Works page.

The Yasnify Score (0–100) is a proprietary composite metric that weighs multiple factors: crime density, 311 complaint volume, school quality, transit access, greenery, traffic exposure, and fire protection. The weighting formula is calibrated for Edmonton-specific data patterns.

3. AI-generated report commentary

Yasnify reports include AI-generated text commentary in addition to deterministic data. This section explains what is AI-generated, what is not, how the AI is constrained, and where it can fail. Disclosure of AI involvement is a legal and ethical requirement under emerging Canadian AI transparency norms (Bill C-27 / AIDA) and reflects industry best practice.

What is AI-generated

Yasnify uses Google Gemini 2.5 Flash (with Gemini 2.0 Flash as an automatic fallback) to produce the following sections of each report:

• Executive Summary — the 4–6 sentence overview paragraph at the top of the report.
• Yasnify Score commentary — the plain-English explanation of the 0–100 score and its tier label (e.g. "Above-average", "Mixed", "Below median"). The numeric score itself is computed deterministically; the AI only describes it.
• Key Insights bullets — the positive / warning / neutral one-line observations.
• Common Questions & Answers — property-specific Q&A generated from the data payload.
• Topic insights — one-sentence summaries for gentrification velocity, traffic exposure, flood risk, snow-clearing priority, fire protection / insurance, and tree canopy.

What is NOT AI-generated

The following report content is computed deterministically from official datasets and is never written or modified by AI:

• Crime incident counts and year-over-year trends (EPS data)
• Building permit lists with permit numbers, issue dates, and declared construction values
• 311 service-request counts and category breakdowns
• Flood-zone boundaries, fire-hydrant distances, and fire-station distances (City GIS)
• School names, distances, and Alberta Education PAT scores
• Zoning codes and permitted uses (Zoning Bylaw 20001)
• Property assessment values (City Assessment & Taxation)
• The Yasnify Score number itself (computed by our scoring formula, not by Gemini)

How AI commentary is generated

Gemini receives a structured JSON payload containing only the factual data extracted from official sources for the property you searched. The AI does not have internet access during generation, does not search external sources, and cannot retrieve any information beyond what we send in that payload.

The Gemini system prompt enforces hard constraints, including:

• Use ONLY facts from the JSON payload — never invent numbers, road names, school names, BIA names, or trends.
• Cite exact figures from the source data with their time window (e.g. "513 reported incidents in 2025 within ~1 km").
• No marketing language, no exclamation marks, no emojis.
• Be honest about weaknesses — not just strengths.
• Use Canadian spelling and plain English (residential audience) or investor-focused language (commercial audience).
• Never call airport zoning overlays a "hazard" — they regulate aircraft noise and building height, not safety risk.
• Never claim work was "done illegally" — state "no permit on record" instead, and remind users the permit dataset starts in 2009.
• Never tell users to "verify with a realtor, agent, broker, lawyer, or inspector" inside answer text.

AI limitations & accuracy

AI-generated commentary is not guaranteed to be accurate. Known limitations include:

• Interpretation errors: the AI may characterise data context incorrectly (e.g. calling an incident count "low" when it is actually average for the area).
• Tone inconsistency: AI text can sound confident even when the underlying data is incomplete, ambiguous, or stale.
• Hallucination risk: despite strict prompt constraints, large language models can occasionally produce plausible-sounding but factually incorrect statements. We apply validation rules to catch obvious cases, but errors may still occur.
• Subjective framing: tier labels and qualitative phrasing are algorithmic interpretations, not objective property assessments.

What AI does NOT do

Gemini commentary in Yasnify reports does NOT:

• Access real-time news, social media, MLS listings, or any external database.
• Know your personal preferences, budget, family situation, or investment thesis.
• Provide legal, financial, tax, or professional real-estate advice.
• Make purchase recommendations ("you should buy this property").
• Predict future crime trends, neighbourhood appreciation, or development plans.
• Replace human judgment from licensed REALTORS^®, appraisers, lawyers, or home inspectors.

Verification required

Always cross-check AI-generated commentary against the underlying data tables in the same report. If the summary says "low crime", verify against the actual EPS incident counts shown below it. If it says "no recent permits", verify against the building-permit list. The raw data tables are the source of truth — the AI commentary is a convenience layer on top.

For critical decisions (offer price, inspection scope, insurance binding, financing), rely on the raw data and consult licensed professionals — not the AI summary.

Google's use of report data

We send Gemini only aggregated property statistics (crime counts, permit counts, zoning code, computed Yasnify Score inputs) for the address you searched. Google does not receive your name, email address, account identifiers, payment information, or search history through the Gemini API. Under our API agreement, Google does not use this data to train its AI models.

See our privacy policy for complete details on sub-processors and AI data sharing.

4. Known limitations & data quality

General limitations

• Reporting bias: public datasets reflect reported incidents (crime, 311 complaints), not actual incidence. Reporting rates vary by neighbourhood, demographic factors, and incident severity.
• Temporal lag: data sources refresh at different intervals (more frequent for crime and permits, annual for school ratings). Reports show a refresh timestamp for each dataset.
• Geocoding precision: crime data is geocoded to intersections and 311 complaints to block-level locations. This protects privacy but reduces spatial precision.
• Incomplete coverage: some properties (new developments, rural areas on Edmonton's edge) may have sparse historical data.

Dataset-specific limitations

• Crime statistics: reflect police-reported occurrences only. Not all crimes are reported or recorded.
• Building permits: coverage begins in 2009; earlier work is not digitized. Permit issuance does not imply code compliance — always verify with the City.
• 311 complaints: reflect resident engagement, not objective quality. High-complaint areas may indicate active community advocacy rather than poor conditions.
• School ratings: based on standardized test scores (PAT). They do not capture arts programs, extracurriculars, special-needs support, or school culture. Enrolment capacity and waitlist data are not available in public datasets.
• Flood zones: based on the 2014 City study. Climate patterns change and flood risk is probabilistic, not deterministic. Always consult insurance brokers for current flood insurance requirements.

5. What Yasnify is NOT

Yasnify is not:

• Legal advice. Reports do not constitute legal opinions on zoning compliance, easements, title defects, or property rights. Consult a real estate lawyer for legal questions.
• Financial advice. Yasnify Scores are research tools, not investment recommendations. Consult financial advisors, mortgage brokers, or CPAs for financial decisions.
• Property appraisal. Reports do not determine market value. Only licensed appraisers can provide compliant valuations.
• Home inspection. Reports analyze public data, not physical property condition. Always hire a licensed home inspector before purchase.
• Professional real-estate advice. Reports are tools for REALTORS^® and buyers, not a substitute for professional guidance. Work with licensed agents and brokers.
• Insurance underwriting. Fire protection class and flood zone data inform insurance decisions but do not replace broker quotes. Always get binding insurance quotes before closing.
• A guarantee of accuracy. Public datasets contain errors, omissions, and lag. Always verify against official City of Edmonton portals, EPS reports, and Alberta Education sources before making property decisions.

6. Liability & indemnification

Yasnify reports are provided "as is" without warranties of any kind, express or implied, including but not limited to warranties of accuracy, completeness, merchantability, or fitness for a particular purpose.

You acknowledge and agree that:

• Yasnify is a research tool, not professional advice.
• All property decisions should be verified independently with licensed professionals.
• Yasnify is not liable for errors, omissions, or outdated information in source datasets.
• You use Yasnify reports at your own risk.

• Building permits: City of Edmonton Open Data Portal or call Development Services at 311.
• Crime data: EPS Neighbourhood Crime Statistics.
• Flood zones: City of Edmonton Planning & Development (311) or consult a land surveyor.
• School ratings: Alberta Education PAT results or visit schools directly.
