## AIPRM

AIPRM installs as a browser extension and injects a prompt library directly into the ChatGPT and Claude interfaces. Instead of retyping the same instructions, you browse a catalog of thousands of prompt templates covering SEO, marketing, copywriting, sales, operations, and support, then apply one with a single click. The company says more than two million users and several large brands rely on it, and each template carries usage counts and community votes so you can judge quality before using it.

Beyond the public library, AIPRM is a prompt management system. You can save your own private prompt templates, organize them into custom lists, star favorites, hide prompts you never want to see, and control tone and writing style through selectors. A Power Continue feature extends the assistant's continue-writing button with expand, simplify, and shorten actions, and higher plans let you customize those actions yourself.

AIPRM also targets teams: multi-seat plans share a private prompt space so everyone uses the same vetted instructions, which helps keep brand voice and output structure consistent across a department or agency. Access is sold as a freemium extension with paid Solo and Team tiers, and the free version can be used indefinitely with lower quotas.

**Pricing & Plans:** Free tier available for unlimited time with lower quotas; paid Solo and Team/multi-seat plans add higher quotas, more private prompt templates and lists, and customization. FAQ pages reference roughly $10 for a Plus-level plan and about $33 for Pro, billed in USD with local sales tax added at checkout.

- **Curated prompt library:** Thousands of community and team-verified prompt templates across industries, each with usage counts and user votes so you can pick proven prompts rather than guessing.
- **Private prompts and custom lists:** Save your own templates for reuse, group them into named lists such as copywriting or legal, star favorites, and hide noise you never want to see again.
- **Team prompt sharing:** Multi-seat plans give a team one shared private prompt space, keeping instructions, tone, and output formats consistent across everyone's AI sessions.
- **Tone and writing style controls:** Selectors let you shift the tone and style of an answer without rewriting the prompt, and paid plans let you define your own custom tones.
- **Works inside ChatGPT and Claude:** The extension runs where you already work, adding the library, lists, and Power Continue actions to the assistant interface instead of a separate app.

**Strengths:** Large, actively maintained prompt library with community voting signals; Private prompt management turns one-off prompting into a reusable team asset; Runs inside ChatGPT and Claude, so there is no context switch; Free tier is usable indefinitely, making evaluation low risk

**Limitations:** Community prompts are not all team-verified, so quality varies; Value depends on using ChatGPT or Claude as your main assistant; Highest quotas and customization require paid plans; all sales are non-refundable

## 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
