## 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

## AskCSV

AskCSV turns a spreadsheet into a conversation. Instead of hunting for the right pivot table settings, you drop a CSV, TSV or Excel file into the browser and ask a plain-English question like which region brought in the most revenue. AskCSV picks the query to run against your data, the database in the tab answers it, and the chart is drawn from the actual result. Every chart also exposes the SQL, so you can audit any figure that matters.

Privacy is architectural rather than a policy promise: the file is read and queried locally in the tab, and the AI never receives the file. It sees only the columns you select, at most ten sample rows, a hundred rows of each result and summary figures. Follow-up questions keep the context of your file and previous answers, so you can narrow things down, switch chart types or ask for totals without starting over.

The tool is explicit about its limits: it handles files only (CSV, Excel and pasted cells), not live databases or Google Sheets, and very large files can run out of memory because everything loads in the tab. You can try it without signing in using free guest credits, then subscribe for a monthly allowance or top up credits as needed.

**Pricing & Plans:** Freemium: $0.25 of free guest credits (about 5 answers) with no sign-in, then $5/month including $5 of usage (about 100 answers), plus add-on credits from $10 for heavier months. Cancel anytime.

- **Plain-English questions:** Ask about your spreadsheet the way you would ask a colleague, and get a chart or a number back.
- **Charts with visible SQL:** Every chart shows the query that produced it, so totals, shares and averages can be checked.
- **Browser-local processing:** The file is opened and queried in your tab and is never uploaded to the service.
- **Multi-turn analysis:** Each question builds on the last, keeping the context of your file and earlier answers.
- **CSV, Excel and pasted cells:** Supports CSV and TSV files, Excel workbooks (every sheet) and data pasted straight from a spreadsheet.

**Strengths:** File stays in the browser; only a small data sample is sent to the AI; Every chart includes the underlying SQL for verification; Free guest credits let you try it with no sign-in; Follow-up questions work without re-uploading the file

**Limitations:** No live database or Google Sheets connections yet; Very large files can exhaust browser memory; The AI can still be wrong, so figures need checking
