Features

Everything you need to capture, organise, and compose your knowledge.

Features

Ultrathink is a knowledge capture and organisation system designed for rapid intake and intelligent processing.

Capture

Ultrathink supports multiple capture methods: browser extension, desktop widget, and direct entry in the web app.

Entry types

The system recognises 20+ content types, each with type-specific processing.

AI conversations:

  • ChatGPT (chat.openai.com, chatgpt.com)
  • Claude (claude.ai)
  • Perplexity (perplexity.ai)

Full conversation threads are extracted and stored for AI analysis.

Documents:

  • PDF files
  • Markdown files
  • Microsoft Word (SharePoint/OneDrive)
  • Microsoft Excel (SharePoint/OneDrive)
  • Microsoft PowerPoint (SharePoint/OneDrive)
  • Microsoft OneNote (SharePoint/OneDrive)
  • Notion pages

Media:

  • Screenshots (captured via extension or widget)
  • Images (uploaded or dropped)
  • Video (YouTube, Vimeo)
  • Audio (recorded via widget)

Text:

  • Links (any URL)
  • Snippets (selected text from pages)
  • Notes (typed directly)
  • Ideas (quick thoughts)
  • Paragraphs (longer text)

Email:

  • Outlook (office.com, outlook.live.com)

What gets captured

Each entry can include multiple data points depending on the source.

From the browser extension:

  • URL and page title
  • Selected text
  • Tab group name and colour
  • Page description (from meta tags)
  • Open Graph image
  • Author and publication date
  • Estimated reading time
  • Your notes

From the desktop widget:

  • Typed notes with rich text formatting
  • Dropped files (PDF, images, Office documents, audio, video)
  • Screenshots (full screen or region selection)
  • Audio recordings (microphone or system audio on Windows)

Metadata extracted:

  • JSON-LD structured data (Article, NewsArticle, BlogPosting)
  • Twitter Card metadata
  • Reading time estimate (words / 220 wpm)

Auto-save

Both the extension and widget use auto-save to minimise friction.

Extension popup: 3-second countdown starts on open. Resets on any interaction. Saves when timer ends or popup closes.

Widget normal mode: 3-second countdown with file/note label displayed. Clears content after save.

Widget expanded mode: 10-second background save. Continues editing without interruption.

Organise

Your knowledge base supports multiple views to match different workflows.

Grid view

The default view shows entries as cards in a responsive grid.

Features:

  • Thumbnail preview from Open Graph images or screenshots
  • Type icon indicator
  • Title and truncated content preview
  • Topic and people tags
  • Quick actions (edit, delete, share)
  • Sort by date, title, type, or manual order
  • Filter by type, topic, person, or entity

Density options:

  • Comfortable: Larger cards with more detail
  • Compact: More entries visible, less detail
  • Spacious: Maximum detail per card

Kanban board

Drag-and-drop task management with customisable columns.

Features:

  • Create, rename, and delete columns
  • Drag entries between columns
  • Drag to reorder within columns
  • Sticky column headers with inline scrolling
  • Sort cards by date, title, or manual order
  • Column collapse for focus

Column management:

  • Empty columns show a delete button (no confirmation needed)
  • Columns persist per user
  • Works with any entry type, not just tasks

Work Plan canvas

A spatial canvas for visual planning and organisation.

Features:

  • Free-form positioning of entries
  • Pan and zoom navigation
  • Grouping and alignment tools
  • Connection lines between related items
  • Export to image

Use this for project planning, mind mapping, or spatial organisation of complex topics.

AI Canvas

A multi-modal workspace for AI-assisted composition.

Features:

  • Compose prompts with attachments from your knowledge base
  • Mark bits of entries (text, images) to include as context
  • Adjust reasoning level (none, low, medium, high, xhigh)
  • Adjust verbosity (low, medium, high)
  • Enable web search for current information
  • View and copy AI responses
  • Customise the system prompt

The AI Canvas is designed for research synthesis, report writing, and complex queries that need context from multiple entries.

AI enhancement

AI processing runs automatically when entries are saved. Each step adds structured metadata.

Summarisation

Entries are summarised based on their type.

Images and screenshots: Vision API describes visual content, extracts text, and identifies key elements.

Audio recordings: Whisper transcribes speech, then AI analyses the transcript for key points and action items.

Documents: Text is extracted from PDFs, Word, Excel, and PowerPoint files. AI provides brief, paragraph, and detailed summaries.

Links: Web pages are fetched and summarised, with web search available for additional context. Private domains (e.g., internal tools, login-required sites) skip summarisation.

Text entries: Snippets, notes, and email bodies are summarised into structured sections: brief summary, key points, and action items.

Research notes: Long-form entries get deep analysis with web search enabled for fact-checking and enrichment.

Classification

AI assigns structured metadata to every entry.

Entity type:

  • Project
  • Task
  • Knowledge
  • Unclassified

Category:

  • Work
  • Personal

Grammar correction: Typos and grammatical errors in your notes are corrected automatically.

Due date extraction: Dates mentioned in content are parsed and assigned as due dates.

Topics and people

AI extracts and matches topics and people mentioned in entries.

Topics:

  • Extracted from content
  • Matched to your existing topic list
  • New topics suggested for review
  • Used for filtering and similarity detection

People:

  • Names extracted from content
  • Matched to your existing people list
  • Linked for relationship tracking

Manage your topics and people lists in Settings.

Relationships

AI finds connections between entries.

How it works:

  1. Your notes are scanned for mentions of other entries
  2. Candidates are resolved using fuzzy matching and AI
  3. Confidence levels are assigned (high, medium, low)
  4. Bidirectional links are created

Similarity detection:

  • Entries with overlapping topics, entities, or people are compared
  • Semantically similar entries are linked
  • Up to 5 similar entries are stored per entry

Query your knowledge base in natural language.

Examples:

  • "What notes do I have about the Q4 budget?"
  • "Find everything related to the marketing project"
  • "What did Sarah say about the deadline?"

AI searches your entries (default: 500 most recent) plus org-shared entries and returns an answer with links to matching items.
