Inspiration

The idea started as an AI tutor for Nigerian students preparing for local national exams. But the deeper I went, the more I realised the real gap wasn't tutoring, it was access. Most powerful AI tools are built for Western users, priced in dollars, and culturally foreign to African users. I wanted to build something that feels like it was made for us, speaks Nigerian local languages.

As the build progressed, the vision expanded. Why limit it to students? A fresh graduate needs a CV. A founder needs a business email. A developer needs a coding partner. Ace became the answer to all of them.

What it does

Ace is an all-in-one AI assistant that brings multiple high-value tools into a single, unified interface. Instead of switching between different apps, users can handle learning, writing, problem-solving, and productivity workflows in one place.

It can:

Answer questions and explain complex concepts clearly
Generate and refine written content (essays, emails, reports)
Create and analyse CVs and cover letters
Assist developers with coding and debugging
Solve and explain mathematical problems step-by-step

Each capability is designed as a dedicated tool within the same system, backed by shared memory and persistent sessions. Conversations and outputs are saved automatically, and responses stream in real time, creating a fast, continuous, and context-aware user experience.

Ace is not just a chatbot, it’s a modular AI workspace that adapts to different user needs without breaking context or flow.

How we built it

Ace was built in phases over several weeks.

Phase 1

Established the foundation — authentication, chat, and memory.

Phase 2

Added persistent conversation history.

Phase 3

Introduced Nigerian-specific features, including OCR and multilingual support.

Phase 4

Built out the full tool suite CV Maker, CV Analyser, Cover Letter, Essay Writer, Codex, Math Mode, I, Email Composer, and Dojo, each inspired by and benchmarked against the best standalone tools in that category.

Challenges we ran into

Memory

The hardest challenge was memory building an AI that genuinely remembers different users across sessions, which required careful Firestore schema design and prompt injection architecture. Getting it to feel natural rather than mechanical took multiple iterations.

Streaming

Streaming across complex UIs was another challenge, especially in Math Mode, where LaTeX rendering, markdown stripping, and step parsing all occur simultaneously on live streaming content.

Scope Management

The biggest product challenge was scope management. Every week, there was a new tool to add, a new feature to build. Learning to say "not yet" and finish what was started before adding more was a discipline I had to develop throughout the build.

Accomplishments that we're proud of

I built a fully functional, multi-tool AI system that goes beyond a standard chatbot experience. Ace combines chat, productivity tools, and domain-specific assistants into one unified interface.

Some key achievements include:

Designing and implementing a modular tool-based AI architecture
Building real-time streaming responses across all features
Creating persistent memory so users can continue conversations across sessions
Integrating multiple AI-powered tools (writing, coding, math, CV generation, etc.) into one system
Delivering a smooth, app-like experience with fast transitions between tools

What we learned

I learnt that building a real product is less about adding features and more about making systems work together reliably.

Key lessons:

Architecture decisions early on heavily impact scalability later
Streaming AI responses require careful UI and state synchronisation
Memory systems are hard to get right, especially when they must feel natural and consistent
Scope control is critical; focus and iteration matter more than feature volume
The difference between a prototype and a usable product is consistency under edge cases
