Where we come in

Tools are the easy part.

The tools above are free because they solve one small problem each. The work we get paid for is deciding which bottleneck is worth removing, wiring a system into a process people will actually follow, and being able to prove the output is good.

01

AI Content Systems

Production pipelines that take a brief to a first draft in minutes, with your voice and your facts — then a human edits.

  • Brand-voice prompt libraries
  • Draft-to-publish workflows
  • Localisation at volume
  • Editorial QA checkpoints
02

Conversational Assistants

Support and sales assistants grounded in your own documentation, so answers come from your content instead of the model guessing.

  • Retrieval over your knowledge base
  • Escalation to a human, by design
  • Answer-quality evaluation suite
  • Analytics on what people actually ask
03

AI Search Visibility

Being cited by AI assistants is becoming its own acquisition channel. We structure your content so it gets quoted accurately.

  • Structured data and entity coverage
  • Answer-shaped content architecture
  • Citation and mention monitoring
  • Competitive share-of-answer tracking
04

Workflow Automation

The unglamorous wins: briefs routed, assets tagged, reports drafted, handoffs that no longer depend on someone remembering.

  • Intake and triage automation
  • Asset tagging and search
  • Reporting and summarisation
  • CRM and project-tool integration
05

Custom Internal Tools

Small, sharp applications built for one team and one job — the kind of thing that never justifies a full software project.

  • Internal dashboards and copilots
  • Document and contract review aids
  • Model and vendor selection
  • Cost and latency budgeting
06

Evaluation & Guardrails

The part most agencies skip. If you cannot measure whether the output is good, you have bought a demo, not a system.

  • Task-specific evaluation sets
  • Regression testing on prompt changes
  • Hallucination and safety review
  • Human-in-the-loop checkpoints
How we work with it

Four rules we do not bend.

A human signs off on client-facing output

Generated drafts are drafts. Nothing reaches your customers without a person who is accountable for it having read it.

Grounded in your content, not the model’s memory

Assistants answer from your documentation with citations. If the answer is not in your material, it says so rather than inventing one.

We will tell you when AI is the wrong tool

Plenty of problems are better solved with a form, a rule or a rewrite. We would rather lose the line item than sell you a system that quietly degrades.

You own the prompts, the data and the pipeline

Everything transfers at handover, documented. No proprietary black box you can only operate by continuing to pay us.

Questions

The ones worth asking.

Start a project

Describe the workflow you want to improve and we will tell you whether AI is the right tool — and what it would cost to run. Email hello@vinscreatives.co.ke or book a call.
