Tools with clear limits.
Simple tools to structure a question. For each one, I explain what it does, who it is for and where its scope ends. Any calculations take place in your browser: nothing is sent or saved.
Each entry explains what it is, who it is for, what its limits are and when it was reviewed. If a tool changes, its date changes too.

AI management maturity self-assessment
Interactive page · local calculation in your browser
Eight questions to give an indicative picture of how an organisation is managing its AI against ISO/IEC 42001:2023.
Open tool →Who it is for
Management, compliance officers and technical teams who need to structure the internal conversation about AI.
Scope
Returns a score, an estimated level and the dimensions worth starting with. The result can be copied as a text summary.
Declared limits
- Measures self-reported perceptions, without verifying evidence.
- The result is indicative: it is not an audit, certification or professional opinion.
- Does not save or send responses: the calculation takes place in the browser.

Regulatory timeline
Browsable timeline · filters by framework and status
Key dates for AI, data, cybersecurity and technical standards, with an official source for each milestone.
Open tool →Who it is for
Anyone who needs to know which rule applies, from when and with what weight before making a decision.
Scope
Each milestone shows its date, jurisdiction, type, status and official source. You can browse by year and filter by framework or status.
Declared limits
- Technical guidance: does not constitute legal advice.
- Dates must be checked against the current official source before using them for a legal decision.
- The selection covers milestones affecting management, certification and governance; it is not an exhaustive regulatory compendium.

Open-data glossary
JSON · open CORS · citable use with attribution
The complete glossary published as JSON: terms, definitions, categories and references.
Open tool →Who it is for
Developers, educators and media outlets who want to reuse authored definitions with clear attribution.
Scope
Includes the term, short and extended definitions, category, aliases, examples, references and canonical URL. Regenerated with each site build.
Declared limits
- Free to use with attribution to Fernando Arrieta and a link to the term's URL.
- These definitions are authored by Fernando: they guide interpretation, but do not certify anything.
- The file reflects the glossary as of the site build date.
-
Embeddable glossary terms
Lightweight iframe per term · /glosario/{slug}/embed
Each glossary term has an embeddable version: a lightweight card with an attributed definition and a link to the source.
Open tool →Who it is for
Websites, virtual classrooms and publications that want to cite a definition without copying it in full.
Scope
A self-contained card with no dependencies and built-in attribution. The term's page remains the primary version.
Declared limits
- The embed displays the short definition; the full text is on the term's page.
- Does not support custom styling: the card preserves attribution.
- Marked noindex: does not compete with the canonical URL.
How I build this index.
Inclusion criteria
I publish a tool when it helps structure a public question and I can keep it up to date. Entries are updated alongside the tool.
How they are built
Static site. Interactive tools use browser JavaScript with no external dependencies: responses are processed locally, and none are sent or saved.
Use and attribution
Free to use with attribution to Fernando Arrieta (fernandoarrieta.org). The full framework is in how I work.
