## 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

## Splodge: Paint, Draw & Art

Splodge splits its interface into two clearly separated worlds. The studio side is built for real artwork: hundreds of brush styles with pressure response, layers and layer groups, masks, adjustment layers, perspective and symmetry guides, Quick Shape for clean geometric lines, re-editable text, and large high-resolution canvases with autosave and crash recovery. A photo effects panel can restyle an imported image with looks such as Cartoon, Oil paint, Neon or Glitch, and the effects stay re-editable so the original photo is never altered. A time-lapse feature replays any painting as a shareable video.

The learning side is deliberately oversized, warm and almost reading-free, aimed at younger artists though enjoyable at any age. Learn to Draw walks users through shapes step by step and awards a star for each attempt. The Coloring Book offers hundreds of outlined pictures to tap-fill, after which a "Grade me!" button evaluates how much was colored and how neatly the user stayed within the lines, responding with sparkles, stars and medals. Every finished piece is saved to a personal My Art shelf.

Child safety is treated as a design constraint rather than an add-on: a parental gate guards every exit, setting and purchase, there are no ads and no outbound links. Splodge is free to start, with an optional subscription unlocking the full studio, plus a one-time lifetime purchase. It is published by Toolbone LLP, a Singapore-based developer.

**Pricing & Plans:** Free to start. An optional subscription unlocks the full studio with monthly, 3-month, 6-month and yearly plans, plus a one-time Lifetime purchase. Billing runs through Google Play and everything sits behind a parental gate.

- **Layered painting studio:** Pressure-sensitive brushes with hundreds of styles, layers and groups, layer masks, adjustment layers, selections, transform tools and re-editable text.
- **AI-graded coloring book:** Tap-fill hundreds of outlined pictures, then press "Grade me!" so the app assesses coverage and line discipline and celebrates with sparkles, stars and medals.
- **Learn to Draw guides:** Friendly step-by-step shape tutorials that award a star for every attempt, building real drawing skill without pressure.
- **Re-editable photo effects:** Apply Cartoon, Oil paint, Neon, Glitch and other looks to an imported photo, and change them later without the original image ever being altered.
- **Parental gate and no ads:** Exits, settings and purchases are locked behind a parental gate, with no advertising and no links leading outside the app.

**Strengths:** Equally strong as a real art studio and as a kids' learning app; AI grading gives encouraging, non-judgemental feedback instead of scores; Strong child-safety design with a parental gate and no ads; One-time Lifetime purchase available alongside subscription plans

**Limitations:** Android only, with no iOS release; Photorealistic, professional-grade painting is not the focus; The full studio requires a subscription or lifetime purchase
