CUSTOM BUILDS
Custom AI tools · built, not bought

Stop duct-taping software that still doesn't work.

I build the custom, AI-powered tool that does — so your business stops running on willpower and 40 browser tabs.

What should you build? → 2-min diagnostic · honest answer, even if it's "not yet"
What I solve

Four expensive problems off-the-shelf can't fix.

If one of these is quietly costing you every week, it's a custom build — and it costs less than the workaround.

The Franken-Stack

01

Five subscriptions duct-taped together, leaking time and client data in every gap. Zapier patches the symptom and adds another bill.

Fix:One custom system that does the whole job — no gaps to fall through.

The Brain Drain

02

Your team can't move without texting you first. The "fix" was a Notion wiki nobody reads. You've built a job where you're the walking help desk.

Fix:An internal AI knowledge base your team chats with — instead of interrupting you.

The Blank Page

03

Hours lost turning client notes into custom roadmaps, recaps and reports. ChatGPT gets you 60% there and sounds nothing like you.

Fix:A generation engine tuned to your exact framework — notes in, on-brand deliverable out.

Dumb Data

04

Hundreds of feedback forms, reviews and call transcripts — and a gut feeling instead of proof. CSV exports and pivot tables don't cut it.

Fix:An insights engine that reads it all and drops a 3-bullet brief in your inbox weekly.

Each one is a custom build — and it costs less than the workaround.

01

Content OS

An autonomous content engine. Instead of a template or a VA, it audits posting history, finds the gaps, writes five complete scripts, and delivers them every Monday.

Diagnostic note · 01

"The problem wasn't 'needs more content' — it was a founder spending every week deciding what to post. So I built a system that audits six weeks of history, finds the gaps, and writes five complete scripts every Monday."

Diagnostic note · 02

"Content was being judged by gut, inconsistently, and it ate 5–10 hours a month. Hiring a reviewer would have added cost and more inconsistency. So I built a tool that scores against a fixed rubric instead."

SalesScore

AI content evaluation. It scores every submission against a fixed rubric and returns feedback automatically — hands-off, with none of the cost or drift of a human reviewer.

DuaComposer

Shipped fast, validated faster — idea to revenue in three weeks.

What I'd do differently: tighten onboarding sooner — the early drop-off was a messaging problem, not a product one.

Diagnostic note · 03

"The goal was to validate quickly, not build a cathedral. I shipped a focused MVP with AI at the core and cut everything that wasn't the one thing users needed."

How I decide what to build

Before you spend a dollar, I look at four things.

01Method

Is there a process you already run that's worth systematizing?

02Constraint

Is there a real bottleneck a tool removes — or just a nice-to-have?

03Timing

Is now actually the moment, given everything else moving?

04Ownership

Are you set up to own the thing once it's live?

"If those don't line up, I'll tell you — sometimes the honest answer is 'not yet.' I'd rather lose the project than build you something you'll resent maintaining."

How it works

Three steps. No 12-week discovery theatre.

01

Diagnose

You show me what's eating your time. I tell you honestly whether to build — and what.

02

Build

Scoped tight, built fast — weeks, not quarters. You see it working as it comes together.

03

Hand off

You own it. It runs without me. Stay on retainer if you want it to keep growing.

Who's behind it

I build the thing, not a slide deck about it.

I'm Mujidah — I spent 5+ years as a product manager shipping SaaS at companies like Wandrian (250K+ monthly users, $3M+/mo) and Bankly, then started building my own products with AI tools.

Four apps shipped, real paying users. GrayTop is where I do that for other people's businesses: diagnose the bottleneck, build the custom tool, and hand you something that runs without me.

Not sure
what you
need?

Take the 2-minute diagnostic. It tells you the honest move — build it for you, build it with you, or build it yourself. Sometimes the answer is "not yet," and I'll tell you that too.
