Human-in-the-loop AI is an approach that keeps people inside an otherwise automated AI workflow, labelling training data, validating or correcting model outputs, and providing review-based feedback so models can improve. Kenya has become a significant location for this work because it pairs a large, English-speaking, analytically capable workforce with established providers in the global AI data supply chain. This guide explains the services involved, the talent, why worker wellbeing must be central, the cost and the data-protection controls UK firms need.

Key terms
- Human-in-the-loop
- A workflow that places human judgement inside an AI process, for labelling, validation or review, where full automation is not reliable or safe enough.
- Review-based feedback
- Structured human assessment of model outputs used to refine and align a model's behaviour over successive iterations.
What human-in-the-loop covers
Answer: It covers data annotation, validation and human review of model outputs, the points where human judgement keeps AI accurate and safe.
Human-in-the-loop work spans several stages of an AI lifecycle. It includes AI data annotation, labelling raw data so models can learn; data validation, checking that labelled or generated data is accurate and consistent; content review, assessing outputs against policy; and review-based feedback, where reviewers rate or correct model responses to align behaviour. Related delivery includes human-in-the-loop transcription, where AI drafts a transcript and a person corrects it. Across all of these, the human role is to apply judgement where automation alone falls short.
Talent and providers
Answer: Kenya offers a large, English-speaking, analytically trained pool and established providers in Sama and CloudFactory.
Kenya produced 123,366 university graduates in 2024, up 24% on the previous year, including 8,627 in computing and ICT, and data analysts earn around USD 787 a month. English is the official language under Article 7 of the Constitution, with the country ranked 19th in the EF EPI 2025 within the High band. Sama, formerly Samasource, and CloudFactory are major data-annotation and content-moderation employers in Kenya and part of the global AI data supply chain, while CCI Global runs after-school AI training and Zalego Academy provides specialist training. See the Kenya talent hub and Kenya digital economy overviews for context.
Worker wellbeing
Answer: Because some review work exposes people to difficult material, fair pay and mental-health support must be treated as essential and contractual.
Not all human-in-the-loop work is benign: content review and moderation can expose people to distressing material, and the sector has faced scrutiny over wellbeing. A Data Labelers Association (DLA) has formed to advocate fair wages and mental-health support for workers. UK buyers should ask providers about pay, exposure limits, content rotation and access to counselling, and write those expectations into contracts with the right to audit them. The dedicated content moderation in Kenya guide covers the highest-exposure end of this work in more detail.
Cost and compliance
Answer: Human-in-the-loop work is delivered at competitive BPO rates, with personal data requiring the UK IDTA and a Transfer Risk Assessment.
Kenyan BPO work is typically delivered at roughly USD 7-15 per hour, against USD 40-60 or more onshore, and data analyst roles sit around USD 787 a month. The Kenya outsourcing rates guide gives the wider picture. On compliance, Kenya has the Data Protection Act 2019, aligned with GDPR and overseen by the ODPC, but holds no UK adequacy decision, so any personal data in the workflow must be transferred under the UK International Data Transfer Agreement supported by a Transfer Risk Assessment. Where data includes special-category information, UK GDPR special-category handling applies. See the IDTA for Kenya guide.
Key Takeaways
- Human-in-the-loop AI keeps people in the workflow for annotation, validation and review of model outputs.
- Kenya offers a large, English-speaking, analytically trained pool and established providers in Sama and CloudFactory.
- Worker wellbeing, fair pay, rotation and mental-health support backed by the Data Labelers Association, must be contractual.
- Personal data in the workflow needs the UK IDTA plus a Transfer Risk Assessment, as Kenya lacks adequacy.
