The Problem Gnosi Solves

Your research is a workflow, not a collection of disconnected apps.

References in one tool, project views in another, notes elsewhere and the final paper in a fourth editor. The friction is not capturing more data, but keeping the trail from every claim back to evidence.

↔

Duplicated effort

The same source and metadata copied across your reference manager, reading notes and project board.

⌁

Evidence without context

Highlights and ideas drift away from the page, paragraph or original text that supports them.

□

Knowledge on borrowed ground

Price hikes or policy changes can trap years of structured research behind vendor rules.

The Gnosi Answer

A single, open chain of custody for your knowledge.

Sources, evidence, notes, links, project views and citations stay connected while files remain readable anywhere.

Core Journey

A complete research cycle in four steps

Start with your own material. AI can assist, but the workflow never depends on it.

01

Capture or import

Add sources via DOI, ISBN, arXiv, PMID, BibTeX or RIS. Save web pages and open PDFs or EPUBs inside your workspace.

Zotero-compatible import · Web Clipper
02

Read with evidence

Annotate sources while preserving citations tied to page, paragraph, chapter or timestamp so claims stay verifiable.

PDF/EPUB Reader · Lineage tracking
03

Connect & structure

Turn reading notes into synthesis. Use wikilinks, knowledge graph, databases, boards, timelines and milestones.

Markdown · Graph · Database views
04

Write & cite

Insert live Gnosi citations into Word or LibreOffice and generate bibliographies without duplicating libraries.

Built Around Real Work

Notion structure, Obsidian connections and a native research layer

A

Sources become actionable evidence

Reference management, readers, annotations, atomic reading notes and precise highlights share one context.

B

Notes can also be data

Markdown pages gain typed fields, relations, formulas, rollups and table, gallery, board, calendar or timeline views.

C

AI remains accountable

Use local or cloud models to ingest and query material while keeping provenance clear and synthesis human-controlled.
