An infinite AI canvas for creative planning, where notes, files, images and links sit in one spatial workspace an agent can read and build on.

Key features

  • Infinite Spatial Canvas: A freeform, unbounded board where notes, images, links and files are arranged by meaning, so layout itself becomes the organisation rather than a folder hierarchy.
  • Context-Aware Agent: The AI reads the whole canvas and understands how ideas connect, then answers questions and researches topics with the surrounding board as context.
  • Native Output Generation: Prompts are turned into canvas content directly, with the agent creating notes, files and web-link cards and placing them where they belong instead of returning plain text.
  • Rich File Previews: PDFs, Word and Adobe documents, markdown, spreadsheets, images and video up to 20 MB open fullscreen in-app, and markdown and CSV files can be edited in place and saved back to the file.
  • Dual Text Editing: Quick notes live directly on the canvas while longer pieces open into a full-page editor, both sharing headings, lists, checkboxes, quotes, code blocks, highlights, images and links.
  • Structure Tools: Collections pack related nodes into tidy columns, nested canvases give a sub-topic its own space, and an unsorted tray parks anything not ready to be placed.
  • One-Click Sharing: Any canvas becomes a read-only link that recipients open without an account, covering nested canvases too, and sharing can be revoked at any time.
  • Template Library: Ready-made boards for app flows, app plans, brand research, branding boards, competitor research, onboarding, storyboards, video briefs and plans, website moodboards and website plans.

Best for

  • Product Planning: Map every screen in an app and the routes between them, then keep features, screens and shipping order in one view instead of three separate documents.
  • Brand Development: Collect the brands, palettes and voices you are borrowing from, then settle type, colour and marks in one place the whole team works from.
  • Competitive Research: Put rival products side by side with your own on a single board and find the gap you can actually take.
  • Video and Film Pre-Production: Block out a shoot frame by frame, hand an editor references, tone and deliverables on one canvas, and follow a video from script to final cut with every asset attached to its step.
  • Website Design Prep: Gather reference sites, type and colour a build should feel like, then lay out every page and its contents before the first component is built.
  • Team Onboarding: Walk a new starter through the tools, files and people one frame at a time on a shareable board.

Unstructured

Unstructured

Freemium

Open-source ETL platform that converts complex documents into structured data for LLMs and GenAI workflows.

Key features

  • Multi-format Ingestion: Supports a broad set of input types (PDF, HTML, DOCX, PPTX, XLSX, EPUB, images, emails, CSV/TSV, compressed archives) to ingest documents from varied sources and normalize them for downstream processing.
  • Modular Bricks and SDKs: Provides reusable, open-source building blocks (bricks) and language SDKs to assemble custom preprocessing pipelines for parsing, cleaning, and transforming document content.
  • Pipeline Orchestration & Enrichments: Routes data through dynamic transformation pipelines that perform partitioning, enrichment, metadata extraction, and content normalization to produce structured outputs tailored for LLMs.
  • Layout Parsing & Chipper Model: Includes layout and document structure analysis (layout parsing) to extract tables, figures, headings, and positional context from complex page layouts for accurate content segmentation.
  • Chunking & Embedding Preparation: Implements intelligent chunking and embedding generation workflows to create LLM-friendly segments and vectors, improving retrieval, RAG, and semantic search performance.
  • Hosted API & Local Libraries: Offers a hosted Unstructured API (API keys required) for cloud-based processing alongside open-source local libraries for on-prem or custom deployments, enabling flexible integration models.
  • Enterprise Platform Capabilities: Provides production-grade Platform features—continuous ingestion, monitoring, partitioning strategies, and scalability—targeted at enterprise workflows and compliance needs.
  • File-type Analytics & Metrics: Collects analytics on processed document types and transformation success to help operators measure ingestion quality and pipeline performance.
  • Convert documents to structured data (supports PDFs, HTML, Word, images, tables, graphs)
  • Modular components ("bricks") for building custom preprocessing pipelines
  • Dynamic transformation and enrichment pipelines for routing and improving data quality
  • Partitioning and chunking to prepare content for LLM consumption
  • Embedding support and integration points for vectorization
  • Layout parsing and inference models (separate inference repository)
  • Python SDK and libraries (unstructured, unstructured-api, unstructured-inference)
  • Containerized deployment options (Dockerfile present in repo) and Makefile-driven install
  • Apache-2.0 open-source licensing for core libraries
  • Enterprise Platform for production-grade workflows, continuous automated processing and scaling

Best for

  • Preparing LLM Training & RAG Corpora: Clean, partition, and chunk large collections of PDFs, manuals, and reports into semantically coherent passages and embeddings for retrieval-augmented generation and model fine-tuning.
  • Automated Document Ingestion for Knowledge Bases: Continuously ingest and transform new documents (contracts, policies, manuals) into structured records for searchable knowledge bases and Q&A assistants.
  • Table and Figure Extraction for Data Pipelines: Parse complex tables, figures, and embedded images from financial reports or scientific papers to convert them into structured datasets for analytics or downstream models.
  • Compliance and Contract Analysis: Extract clauses, metadata, and named entities from legal and regulatory documents to populate contract management systems and support compliance workflows.
  • Invoice/Receipt Processing: Normalize and extract line-items, totals, dates, and vendor information from invoices and receipts to automate AP workflows and accounting ingestion.
  • Migration of Legacy Documents: Convert large legacy document collections (scanned PDFs, archived emails, disparate formats) into structured, searchable formats to modernize enterprise data stores.
  • Prototype to Production Pipelines: Use open-source bricks to prototype document parsing locally, then scale to the Unstructured Platform for continuous, monitored production processing with enterprise controls.
  • Preprocessing document corpora to create high-quality input for retrieval-augmented generation (RAG) pipelines
  • Extracting tables, figures, and structured fields from PDFs and scanned documents
  • Continuous ingestion and enrichment of enterprise documents for knowledge bases
  • Generating embeddings and chunked passages for semantic search over documents
  • Receipt, invoice, and financial filings parsing (example pipelines and archived repos exist)
  • Building document Q&A or chatbot applications using cleaned, structured document content
