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 [Profile (Markdown)](https://openaitools.app/tool/appen-com.md) ## Toki Toki pitches itself as an executive assistant rather than a productivity app, and the framing matters. Instead of an inbox of to-dos waiting for you to triage, Toki connects to your sources, finds the matters that are actually important, and works them. It syncs email, calendars, Slack and devices so it can see the whole picture, then uses that context to decide what deserves your attention today. Interaction is deliberately conversational and multi-modal. You can text Toki as you would a person, send a voice note while walking, or forward a screenshot and have it turned into an event. It can also go the other direction and call you when something is time-sensitive, which is how the Call Me feature is positioned. Over time it builds a memory of your habits and preferences: which meetings you accept, how you like your days structured, what you want protected as deep-work time. Control is an explicit part of the design. Toki proposes an action and asks for approval before it proceeds with anything consequential, so the assistant moves fast without acting unilaterally. The product also handles group coordination through one shareable booking link, monitors prices, flights and news as triggers, and runs across iPhone, iPad, Apple Watch, Mac and Android. Toki's site reports more than 5 million users, a 4.9 app rating and coverage from outlets including Forbes, The Verge, Fast Company and Nikkei. One notable change: the standalone WhatsApp experience was retired after WhatsApp's Business Solution Terms were updated to prohibit standalone AI products, and Toki now points users to its own mobile apps instead. **Pricing & Plans:** Freemium with a free tier and paid subscription plans available through the App Store and Google Play. Features such as reminders and calendar creation are widely used for free, while heavier usage and premium capabilities sit behind in-app subscriptions and trials. - **Matters, auto-discovered:** Sync email, calendars, Slack and other tools and Toki surfaces the tasks and goals that matter instead of waiting for you to file each one manually. - **Voice, image and text input:** Speak, type or send a screenshot. Toki accepts all three, replies in kind, and can phone you when something genuinely needs attention. - **Natural-language scheduling:** Create events, reschedule, block deep-work time and resolve conflicts by describing what you want in plain language rather than clicking through forms. - **Memory of your preferences:** Toki learns how you plan and what you prefer, so reminders sharpen and recommendations fit your working style over time. - **Triggers and monitoring:** Set Toki to watch prices, flights and news and alert you when conditions change, turning it from a scheduler into an ongoing monitor. - **Booking links:** Share one link and let people pick slots that already fit your calendar, with no back-and-forth email chains. **Strengths:** Handles real scheduling work in plain language instead of form-driven UIs; Multi-modal input: voice notes, screenshots and text all create calendar events or reminders; Proactive discovery of important matters across email, calendar and Slack; Approval system keeps you in control of what it does on your behalf **Limitations:** No longer available inside WhatsApp after the platform-wide WhatsApp Business Solution Terms change; Requires installing a mobile app instead of working purely through an existing chat thread for former WhatsApp users; Advanced proactive features work best once you connect several sources (email, calendar, Slack), so value depends on how much you sync; Heaviest value is on Apple hardware; the Apple Watch and Siri experiences have no full equivalent elsewhere [Profile (Markdown)](https://openaitools.app/tool/toki.md) ## Frequently Asked Questions ### How do Appen and Toki compare in monthly traffic?
