Vinsighte's Visis app uses AI-powered OCR and computer vision tuned to African accents to read text aloud for visually impaired students; a UN-documented rollout across 7 Nigerian institutions reports over 90% reading independently.

Context

Founded in Lagos in 2020 by Oluwatomisin Kolawole and Oyolola Caleb, Vinsighte built Visis, a mobile app using AI-powered OCR and computer vision to read printed text aloud and help visually impaired users identify objects, colours and surroundings, tuned specifically to African accents and multiple local languages, unlike most mainstream screen readers.

Objectives

Open printed educational materials to visually impaired students who previously could only access them with a human reader.

Activities

Between December 2020 and July 2023, Vinsighte deployed Visis across seven schools for the visually impaired in four Nigerian states, reaching more than 8,000 people, with support from the ACT Foundation, Merck, the Rotary Club, the Roddenberry Foundation, GIZ, Orange Corners and MIT Solv[ED], documented through the UN's SDG Partnership Platform.

Results

Feedback collected from students and teachers across the seven institutions found that more than 90% of students could independently use the app to read printed educational materials they previously could only access with a human reader.

Conclusions

The reported outcomes are drawn from partner and program self-reporting rather than an independent third-party evaluation, and public information does not disclose total funding raised - a gap that formal impact evaluation could help close as the tool expands beyond its initial Nigerian deployment sites.

Conditions for success

  • AI/OCR tuned to African accents and local languages rather than relying on mainstream (Western-tuned) screen readers
  • Multi-funder philanthropic/development support enabling free or low-cost deployment
  • Direct partnership with schools for the visually impaired for real-world testing and feedback

Common failure modes

  • Reported outcomes rely on partner/program self-reporting rather than independent evaluation
  • Total funding raised is not publicly disclosed, limiting transparency
  • No independent accuracy testing of the OCR/computer-vision models has been published
