One assistant for questions, writing, code, images and documents — instead of a dozen tabs and tools.
Sentra keeps it simple: a clean chat that understands what you upload, searches the web when you need current facts, and gives you answers you can actually use.
Capabilities
Everything you'd expect from a modern AI — in one place
Sentra Chat is live today. Studio and Lab will extend it to design and development.
Ask anything and get clear, well-structured answers — explanations, writing, planning, analysis and math.
Attach images, PDFs and text documents and Sentra reads them to answer, summarize, or pull out what matters.
Turn on search and Sentra brings in current information and cites the sources it used.
Get complete, syntax-highlighted snippets with one-tap copy — and help debugging your own code.
Dictate with your voice, have replies read aloud, and work in a tidy light or dark theme.
Powerful AI that's simple and affordable — built in Ghana, for everyone.
