## Appen

Appen is one of the oldest pure-play AI data companies, tracing its roots to 1996 when it began building human-labeled datasets for speech recognition and NLP. Over three decades it supported successive generations of model development — search relevance in the 2000s, machine translation, deep-learning vision annotation, Transformer-era semantics, GPT-3 scale corpora, RLHF for conversational AI, and now agentic and multimodal foundation models.

Today Appen positions itself around six specialised capability areas: Frontier Alignment (chain-of-thought reasoning traces, SME RLHF, supervised fine-tuning demonstrations, adversarial red teaming), Agentic AI (golden trajectories, RL environment design, failure-mode taxonomies, SWE-driven evaluation), Multimodal and Speech AI (multilingual ASR and conversational corpora, expressive TTS annotation, VLM training data, video action labelling), Physical AI (LiDAR point-cloud annotation, multi-camera sensor fusion, robotics demonstration trajectories, world-model rollouts), Model Integrity (hallucination benchmarking, bias detection, regulatory audits and continuous monitoring), and Research Services (context engineering, calibrated LLM-as-a-judge, synthetic data and custom benchmarking).

Delivery runs through Appen's AI Data Platform (ADAP), which blends automation with human oversight, and the company cites SOC 2 and ISO 27001 certification, 500+ global locales, and a client roster that includes major cloud, search, retail and aerospace organisations. Appen does not publish self-serve pricing; engagements start with a scoping conversation and are quoted per project, so cost depends on data volume, language coverage, modality and annotation complexity.

**Pricing & Plans:** Enterprise/contact-for-pricing. Appen does not publish self-serve plans; projects are scoped and quoted individually. Appen also sells off-the-shelf (OTS) datasets and crowd/contractor workforce programs with separate terms.

- **Frontier alignment data:** Chain-of-thought reasoning traces, SME-level RLHF, supervised fine-tuning demonstrations and adversarial red teaming for the most capable models.
- **Agentic AI datasets:** Golden trajectories, RL environment design, failure-mode taxonomies and software-engineering-driven deep evaluation for autonomous agents.
- **Multimodal and speech corpora:** Multilingual ASR and conversational speech data, expressive TTS annotation, vision-language model training data, video action labelling and voice-agent evaluation.
- **Physical AI annotation:** LiDAR point-cloud labeling, multi-camera sensor fusion, robot demonstration trajectories, world-model rollouts and embodied interaction logs.
- **Model integrity and evaluation:** Hallucination benchmarking, bias detection, regulatory audits and continuous monitoring, plus independent model evaluation.
- **AI Data Platform (ADAP):** A production platform that combines automation with human oversight, with SOC 2 and ISO 27001 certification and 500+ locales covered.

**Strengths:** Three decades of annotation methodology, tooling and workforce management experience; Very broad coverage: frontier alignment, agentic, speech, multimodal, physical AI and evaluation in one vendor; 500+ locales and multilingual expertise that most in-house teams cannot match; Enterprise-grade security posture (SOC 2, ISO 27001) and publicly listed governance

**Limitations:** No transparent self-serve pricing; every engagement requires a sales/scoping cycle; Enterprise-oriented contracts can be heavy for small teams or indie developers; Quality depends on workforce management, so results vary by project and locale; Overlaps with many cheaper specialist annotation vendors, making vendor selection non-trivial

## PublicView

PublicView positions itself as a "public company intelligence platform" built on top of SEC filings. Rather than summarizing documents from model memory, every answer is retrieved from indexed filing excerpts and returned with inline citations you can inspect, so the evidence chain stays attached to the claim. The platform supports three research depths — Quick Mode for fast fact extraction, Deep Mode for entity and relationship mapping, and Track Mode for continuous monitoring — letting users match effort to the question at hand.

Beyond conversational Q&A, PublicView structures filings into other views. A knowledge graph maps companies, people, products, ownership and risk into an explorable network with source-linked connections, a relationships table answers "who is connected to whom and how," and a timeline lays out dated events so you can see how strategy, leadership and risks changed across periods. Watchlists add automatic monitoring: when an 8-K, 10-Q or Form 4 is filed, the platform surfaces an AI-summarized alert so time-sensitive disclosures do not slip past a research cycle. An IPO calendar and lifecycle tracker round out the coverage for companies before and after listing.

The product is aimed at anyone who works from filings: allocators tracking risks and verifying management claims, analysts comparing competitor strategy across 10-Ks and S-1s, lawyers reviewing legal matters across multiple issuers, and journalists hunting for connections when an 8-K drops. PublicView publishes a single flat subscription, and the site explicitly notes that the tool is for research only and does not provide financial advice — outputs are expected to be verified independently.

**Pricing & Plans:** PublicView Pro is a single flat plan at $9.99 USD per month, starting with a 3-day free trial that requires a card and can be canceled anytime. The plan includes SEC-grounded AI chat, deep financials, the knowledge graph, company monitoring and filing alerts, and IPO research, subject to daily limits published on the site (5 Quick analyses, 5 Deep analyses, 50 AI calls, 250k charged tokens and one active analysis).

- **Grounded chat with inline citations:** Ask plain-English questions about 10-Ks, 10-Qs and 8-Ks. The assistant retrieves the relevant filing excerpts and streams an answer with citations you can open to inspect the source text.
- **Visual knowledge graph:** Deep Mode extracts entities and relationships from filings and maps companies, people, products, ownership, strategy and risk into a dual-view network where every node links back to evidence.
- **Relationships table and event timeline:** Search extracted connections to answer who is tied to whom and how, then follow dated events across filing periods to see how leadership, strategy and risks evolved.
- **Filing alerts, watchlists and Form 4 tracking:** Add companies to a watchlist and get AI-summarized notifications when a new 8-K, 10-Q or Form 4 lands, with insider transactions organized for quick review.
- **Multi-company research and IPO coverage:** Compare issuers side by side, work across tickers, CIK numbers or company names, and track IPO research and post-listing lifecycle events in the same workspace.

**Strengths:** Every AI answer is tied to filing excerpts with inline citations you can inspect; Covers the whole loop: Q&A, graph, relationships, timeline and alerts in one workspace; Straightforward single-tier pricing at $9.99/month with a 3-day free trial; Form 4 insider tracking and IPO lifecycle coverage extend it beyond standard filing Q&A

**Limitations:** Published daily caps (5 Quick analyses, 5 Deep analyses, 50 AI calls) can feel tight for heavy research days; Free trial requires a card, so it is not a no-commitment sandbox; It is a research tool only and does not provide financial advice or trade execution
