A desktop workspace for thinking and building with AI

What you build with AI
deserves more than a quick chat.

The best thinking you do with an AI vanishes into a scroll of throwaway conversations โ€” unsourced, unstructured, impossible to build on. Minerva is where that work lands and stays: knowledge you can check, connect, and keep. You and the AI build it together โ€” with you fully in control.

Full app window: sidebar with a thoughtbase, a note open in split view (source + live preview), and the query panel visible. Use the dark theme.

The Big Idea

Thoughtbases: webs of human and AI thought

A Minerva thoughtbase is where your thinking on a subject lives and grows. Instead of scattered documents and lost chat threads, you collect what you're working through as notes โ€” and those notes link to each other, so ideas connect the way they do in your head. Some you write yourself; some you draft side by side with the AI. Over time it becomes a living map of what you know, not a folder of dead files.

๐Ÿงต

Notes of every kind

A note can be a stray paragraph, a full essay, a table of data, a diagram, an image, a math derivation, or a captured web page. Whatever the thought needs.

๐Ÿ”—

Linked, not filed

Connect any note to any other with a link โ€” cite it, support it, contradict it, build on it. Follow the threads instead of hunting through folders.

๐Ÿค

Yours and the AI's, together

Write by hand when you want to, or let the AI draft, summarize, and gather โ€” with you approving what actually lands. Either way, it's yours to keep.

A view that conveys "richly linked notes": several notes visible with wiki-links between them, a mix of media (text, a chart, an image, a source), and hover-preview of a linked note. The connections should read at a glance.

The Editor

An editor that keeps up with your thinking

A fast CodeMirror 6 surface with live preview. Write plain markdown; get rendered callouts, math, diagrams, charts, and code without leaving the keyboard.

  • Three view modes โ€” source, preview, or split, toggled instantly.
  • Wiki-links & typed links โ€” [[note]] plus 11 semantic link types (supports, rebuts, depends-on, supersedesโ€ฆ) each color-coded.
  • Rich blocks inline โ€” callouts, tables, footnotes, highlights, math, diagrams, lists, and tables.
  • Code sections that run โ€” Python, SQL, SPARQL, and Vega/Vega-Lite charts render live against your data, enabling powerful data visualizations.
  • Voice dictation โ€” Native speech-to-text, take your notes by voice with AI-powered expansion.

The Knowledge Graph

A knowledge graph your AI can actually read

On every change, Minerva reads the structure out of your writing โ€” titles, tags, links, metadata, even data tables โ€” and weaves it into a knowledge graph: a precise map of everything you've written and how it connects. That map is what lets the AI search for your real notes instead of guessing, and use them with context and understanding.

  • Grounded, not guessed โ€” the AI queries your knowledge graph to answer from what you actually wrote, and points back to the exact notes it drew on.
  • Insights surfaced for you โ€” ask it to trace how a claim is supported, find where your notes contradict each other, or spot patterns across hundreds of them.
  • Built automatically โ€” titles, #tags, wiki-links, metadata, and data tables all fold in on save. No schema wrangling.
  • Query it yourself, too โ€” a built-in query panel is right there when you want to interrogate everything directly. Industry-standard SQL and SPARQL query languages supported.

Data & Analysis

Bring data into your thinking

Drop a CSV into your thoughtbase and it becomes a queryable table. Query it with SQL, run Python right in your notes, chart the result, and let Minerva help you find what's interesting.

๐Ÿ

Python cells

A python code fence turns any note into a notebook. A minerva.* library API โ€” notes(), sparql(), sql(), table() โ€” hands you your own library as data; output renders inline.

๐Ÿ—ƒ๏ธ

CSV โ†’ SQL tables

Any .csv becomes a DuckDB table with inferred types. Run SELECT/WITH queries and bind results straight into charts.

๐Ÿงฎ

The library is the data source

Notebooks live inside the thoughtbase, not the other way around. Derived outputs save as notes with a derivedFrom link back to the computation.

๐Ÿ“ˆ

Generate Visualizations

Point Minerva at a table and it proposes the right charts for the shape of your data โ€” as a note you review.

๐Ÿ”Ž

Find Outliers

Flag anomalous values in tabular data, with the reasoning written up as a reviewable note.

๐Ÿ”—

Find Correlations

Surface the strongest relationships across your data before you go looking for them by hand.

Tools for Thought

Skills โ€” thinking moves, one click away

Minerva ships with a library of skills: structured thinking operations you invoke from the Learning, Research, and Analysis menus. Each runs a careful prompt over your note and returns something you review. Author your own in a markdown file; they show up in the menus alongside the built-ins.

You Decide

The AI proposes. You confirm.

"The AI suggests; you decide. What it produces is evidence for you to weigh and file โ€” never a change to what you know until you say so."

โ€” Minerva's core design principle

Nothing an AI generates touches your thoughtbase directly. Every suggested claim, edit, tag, or source arrives as a proposal you review side by side and accept with a single keystroke โ€” or reject. Approved changes are written into your notes; ignored ones simply expire.

  • Review before it counts โ€” see exactly what would change, side by side, before it does.
  • You set the line โ€” new claims require your sign-off; trivial tags can apply quietly. Tune what needs approval.
  • Full provenance โ€” everything the AI touches records what proposed it and when.
  • Guaranteed, not promised โ€” a built-in integrity check can prove nothing the AI created ever skipped your approval.

Structured Reasoning

A vocabulary for how you know things

Under the hood, Minerva models the shape of an argument, not just its text. Its thought ontology captures claims, the grounds and warrants behind them, and the ways reasoning goes wrong โ€” so your thoughtbase can hold not only what you believe, but why.

๐Ÿงฉ

Claims & evidence

Claims, grounds, warrants, backing, qualifiers, and rebuttals โ€” an extended Toulmin model of argument.

โ“

Questions & hypotheses

Track open questions, tentative hypotheses, findings, and the tensions between competing ideas.

โš ๏ธ

Epistemic defects

Name fallacies, cognitive biases, rhetorical moves, and structural problems where reasoning breaks down.

๐Ÿ“Œ

Anchored excerpts

Pin verbatim quotes to a source by page, line, or text anchor โ€” evidence you can always trace back.

๐Ÿงฌ

Provenance throughout

Aligned with W3C PROV-O: who or what created each node, and when, is always on record.

๐Ÿ”

Queryable structure

Because it's all connected and queryable, you can ask: which claim is load-bearing? What's unsupported?

Sources & the Web Clipper

Capture the web, keep the receipts

Minerva manages the sources behind your thinking โ€” PDFs, web pages, papers, books โ€” with real metadata and citations. The companion browser clipper saves what you're reading in one click, correctly, even behind a login.

  • Minerva Clipper โ€” one-click web capture that grabs the rendered page and a canonical source ID; save a selection as a linked excerpt.
  • Import anything โ€” PDFs (with OCR), DOI / ISBN / arXiv IDs, BibTeX, and Zotero RDF exports.
  • Real metadata โ€” author, date, DOI, abstract, reading status, and collections โ€” manual or auto-extracted.
  • Source viewer โ€” read the source inline, anchor excerpts, and see every note that cites it.
  • Citations & bibliographies โ€” CSL styles (APA, Chicago, MLAโ€ฆ) and BibTeX export.

Stop losing your best thinking.

The insights you get when working with AI are worth keeping. Give them somewhere to live โ€” structured, sourced, and checkable โ€” where you and the AI can keep building on it instead of starting every conversation over.

That's Minerva.
