## Labelbox

Labelbox occupies an unusual position in the AI stack: it does not primarily sell a chatbot or a generator, it builds the environments and data that models learn from plus the agents that take over recurring engineering and research work. The homepage claim is direct — frontier AI labs train on Labelbox environments and expert data, while engineering and research teams hand their recurring backlog to agents running on Recursion. A recent Series E of more than $100 million signals a heavily funded bet on that thesis.,For enterprises, the newer half of the product is Recursion. Agents are triggered by real signals — a failing build, a PagerDuty alert, a new dependency release, a fresh model checkpoint, or a Monday morning schedule — and then work in the background until the job is done. The examples the company promotes are concrete deliverables rather than summaries: a tested pull request with a preview link, a postmortem draft in Confluence with every event sourced, an ablation table naming the changes that mattered, or a patch for each exposed service after a critical CVE. A grader agent scores each run, and the graded session leaves behind memories, notes and skills that the next session reads before it acts.,The original foundation remains the data business: labeling, annotation, curation and model evaluation supported by expert human reviewers, used for computer vision, NLP, supervised fine-tuning, RLHF and red teaming. In practice the two halves reinforce each other, since the environments that produce high-quality training data are the same environments where agents learn to do real work. Pricing is enterprise-style, routed through sales conversations and shaped by data volume and agent usage, with no public self-serve tier.

**Pricing & Plans:** Contact for pricing. Labelbox does not publish self-serve plans or public rate cards; its pricing route instead directs interested teams to talk to sales, and cost is shaped by data production scope, agent deployment and enterprise requirements. There is no published free tier. Prospective customers should request a quote based on their volumes and use cases.

- **Data labeling and expert annotation:** Structured annotation, curation, model evaluation and human-in-the-loop review across vision, language and generative tasks, used to build the training and eval data behind production models.
- **Autonomous agent sessions:** Recursion agents start on their own from builds, alerts, commits, checkpoints and schedules, then work in the background until the task is finished and reviewable.
- **Domain specialists by function:** Specialist agents cover software engineering, reliability, security, ML research, evals, R&D, product and finance workflows, from flaky test fixes to postmortem drafts and vulnerability patches.
- **Graded outcomes that compound:** Every agent run is scored by a grader, and graded sessions leave memories, notes and skills that the next session reads before acting, so quality compounds over time.
- **Native tool and data integrations:** Agents operate against the tools teams already use, including GitHub, Jira, Linear, Slack, Datadog, PagerDuty, BigQuery, Databricks, Vercel and cloud providers.

**Strengths:** Covers both sides of the problem: training and eval data production plus agents that act on recurring work; Backed by a recent $100M+ Series E and adoption by frontier AI labs, indicating real funding and demand; Agent runs produce concrete deliverables with proof — tests, reruns, ablations — rather than unverified suggestions; Integrates with the toolchain teams already run: GitHub, Jira, Linear, Slack, Datadog, PagerDuty, BigQuery and Databricks

**Limitations:** No self-serve pricing or open signup: everything routes through a sales conversation, which slows down evaluation; The platform assumes real engineering and research infrastructure (GitHub, cloud providers, data warehouses) to deliver value; Positioning has shifted quickly toward autonomous agent sessions, so teams wanting only labeling workflows may find it heavier than needed

## 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
