Executable expertise
Turn your expertise into executable AI.
Capture your reasoning, methods and decision logic as reusable AI Skills you can run, share, publish and export across any AI model.
Current Reality
Your expertise is trapped — and fragile.
When you build complex instructions, prompts and agent behaviours directly inside a single AI platform, your methodology becomes dependent on that provider.
Model dependency
Models, APIs and platform behaviours change. Workflows built around them can degrade, break or require rebuilding.
Platform lock-in
Your reasoning is tied to one provider's formats and environment. Move platforms and you may need to recreate it.
The Shift
Own your reasoning. Run it anywhere.
Skillsize separates your reasoning from the underlying model and packages it as a portable, executable AI Skill.
You define the reasoning framework. You own the methodology. Run it across AI environments, adapt it as models change, and keep improving it without rebuilding your expertise from scratch.
The model is interchangeable. Your reasoning is the asset.
Product
Build the reasoning behind the work.
Turn complex professional tasks into structured AI reasoning frameworks using reusable actions for analysing, extracting, comparing, evaluating, transforming and producing outputs.
Instead of writing one giant prompt, you define how the work should actually be done.
Drop in a brief. Skillsize reads it, infers the constraints and composes the right reasoning steps.

Examples
From complex work to executable Skills.
These aren’t “summarise this PDF” prompts. These are pieces of professional work.
Leadership Due Diligence
Analyse leadership teams against defined criteria, identify risks and generate structured assessments.
Strategic Workforce Planning
Combine workforce data, business priorities and expert assumptions to identify future capability requirements.
Market Strategy
Assess market attractiveness, competitive dynamics and entry options using a repeatable strategic framework.
Operational Improvement
Identify bottlenecks, optimise processes, and prioritise interventions against business impact.
Differentiator
Built for work that actually matters.
More than prompts. More than automation. Skillsize turns expert methodologies into controlled, traceable AI execution.
Structured reasoning, not one-shot prompting
Break complex work into sequenced reasoning stages — analysis, comparison, evaluation, judgement and synthesis — so AI follows the methodology rather than improvising its way to an answer.
Human judgement, built in
Add human-in-the-loop stage gates at critical points. Review evidence, challenge analysis and approve decisions before the AI progresses.
Designed to reduce hallucination risk
Ground execution in defined inputs, evidence and carefully sequenced reasoning — with validation points throughout the process rather than relying on a single model response.
Traceable by design
See how the work was performed, what evidence was considered and how conclusions were reached. Export documented methodologies and outputs for review, governance or audit.
Sensitive data protected before AI processing
Strip PII and pseudonymise sensitive client information before it is processed by underlying AI models, helping experts use AI on sensitive professional work with greater control.
Model independent
Your methodology shouldn’t belong to one AI provider. Build once in Skillsize and export your Skills across ChatGPT, Claude, Microsoft Copilot and other AI environments.
Work Mode
Put your expertise to work.
Give Skillsize a brief. Work Mode turns your AI Skills into an agentic execution team.
Select the Skills you want to use — or let Skillsize identify the right combination — then execute them together against a real client or business challenge. Skillsize coordinates the reasoning, analysis and outputs across each Skill to produce a decision-ready deliverable in minutes.
One brief. Multiple Skills. One outcome.
You don’t chat with your expertise. You put it to work.
Bring the brief
Upload the question, challenge, documents and supporting evidence.
Assemble the expertise
Choose the Skills you need, or let Skillsize determine the right combination for the work.
Execute the methodology
Skills work individually or together, following their defined reasoning frameworks, evidence requirements and human review stages.
Deliver the outcome
Turn the analysis into a structured, professional deliverable — with the underlying work and methodology traceable.
Portability
Build once. Run anywhere.
Your expertise shouldn’t belong to an AI model.
Build your Skill in Skillsize, then export it for use across ChatGPT, Claude, Microsoft Copilot and other AI environments — or as portable Markdown instructions.
As AI models change, your reasoning framework remains yours.
