## Markup: Document Annotation

Markup is an annotation tool focused on one core job: turning free-form text into structured datasets that are ready for NLP and machine learning. Instead of wrangling spreadsheets, you work directly with the document and mark up the pieces that matter, whether that is named entities, fields, relationships or categories. The result is a consistent, machine-readable dataset you can export into a training or evaluation pipeline.

It is aimed at developers, data scientists and research teams who need to build labelled corpora quickly. Rather than forcing everything through a heavyweight enterprise platform, Markup keeps the interface lightweight and task-focused so annotators can move fast, and it leans on AI to propose likely labels and extractions that a human then confirms. That combination helps teams bootstrap datasets far faster than purely manual labelling while keeping a human in the loop for accuracy.

Markup runs in the browser, with an interactive demo available on the site and a sign-up path to create projects. It markets itself as a free, open annotation tool, making it accessible for small teams, prototypes and research work where budget and setup time are limited.

**Pricing & Plans:** Free to use, with an interactive demo on the site and a sign-up flow to start annotating. No paid tiers are advertised.

- **Text to structured data:** Mark up documents and free text to extract names, entities, relationships and fields into clean tabular or JSON output.
- **Designed for NLP and ML:** Built for NLP and ML workflows, so exported datasets plug into model training pipelines without heavy reformatting.
- **AI-assisted annotation:** AI assistance proposes labels and extractions to reduce repetitive manual work, while you keep final control over correctness.
- **Browser-based demo:** An interactive demo lets you test the annotation flow before committing to a full project setup.

**Strengths:** Purpose-built for converting free text into structured, model-ready data; AI assistance speeds up annotation while leaving final control to the human; Simple, task-focused browser interface with an interactive demo; Free and approachable for prototypes, research and small teams

**Limitations:** As an early-stage tool, documentation and community support are lighter than mature annotation suites; Automatic AI extraction still needs human review to confirm labels are correct; Requires JavaScript and a browser session, with no heavy offline or desktop workflow; The interface is designed for focused annotation tasks rather than full project management

## Open WebUI

Open WebUI is an open-source, self-hosted interface for working with AI models. Instead of renting access to a single vendor's chatbot, you run the interface on your own hardware or cloud tenancy, then connect whatever models you want: local runtimes such as Ollama, OpenAI-compatible endpoints, Anthropic, or a mix of local and remote. Everything a team produces — conversations, prompts, models, skills and tools — stays in an environment you administer.

The platform has grown well beyond a chat window. Retrieval-augmented generation, web search, document understanding, voice input and output, and vision are built in, and Python tools, functions and pipelines let developers script custom behaviour and share it. On the operations side it offers enterprise features such as SSO, role-based access control, audit logs, data residency options, and on-premises, hybrid or fully air-gapped deployment for regulated environments. White-labeling and custom branding are also available for organizations that want their own look.

Open WebUI is distributed free of charge under an open-source license and can be installed with a single pip or Docker command, with no account required to get running. A separate enterprise offering is available for organizations that want commercial support, compliance guarantees and managed rollout help, which is quoted on contact. A large community maintains a public hub of prompts, models, tools and functions, so much of what teams need is already shared and ready to install.

**Pricing & Plans:** The core platform is free and open source, installable via pip or Docker with no account required. An enterprise tier with support, compliance and deployment assistance is quoted on contact.

- **Any Model, Any Endpoint:** Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
- **Retrieval and Search Built In:** RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
- **Python Tools, Functions and Pipelines:** Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
- **Enterprise Controls:** SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.
- **Community Hub:** Browse and install prompts, models, skills and tools contributed by hundreds of thousands of community members.

**Strengths:** Free and open source with no account needed to install; Works with local and cloud models through a single interface; Strong privacy posture: your data and models stay on your infrastructure; Extensive enterprise features including SSO, RBAC and audit logs

**Limitations:** Self-hosting requires you to handle servers, updates and backups; Some enterprise capabilities and support sit behind a paid, quote-based tier; Feature depth means a learning curve for non-technical administrators; Local model performance depends heavily on your own hardware
