Maturity
Pilot
Promoter
Institute of Public Finance (IPF), with Mzalendo Trust, Youth Senate Kenya, and Machakos County Government
Sauti ya Bajeti ('Voice of the Budget') is an AI-powered WhatsApp chatbot built by the Institute of Public Finance (IPF) with Mzalendo Trust and Youth Senate Kenya, in partnership with Machakos County Government, as an Open Government Partnership commitment to make county budgeting more accessible.
Objectives
To let residents ask budget questions in everyday language via WhatsApp — Kenya's most widely used messaging platform — and receive instant, sector-specific figures drawn from official county budget documents, strengthening two-way communication between citizens and government on public finance.
Activities
Beyond information retrieval, the platform lets residents vote on priority spending areas, submit feedback through polls and surveys, and track how their input fed into final county budget decisions.
Conclusions
As of the sources reviewed, the platform was newly launched, with a formal evaluation of citizen engagement and platform effectiveness scheduled for December 2026. No usage statistics, satisfaction data, or budget-outcome evidence had been published yet, and the platform has not been reported as extended beyond Machakos County.
Implementation
Indicative cost
Low (< €50k) — No cost figures published; inferred as low-cost given the single-county scope and reliance on an existing WhatsApp messaging channel built by a civil-society institute — inferred from programme description, not stated.
Time to results
Medium (1–3 years) — Launched 2025, with a formal evaluation of citizen engagement and platform effectiveness scheduled for December 2026.
