What is Skillsize?
Skillsize's official website positions itself as "Turn your expertise into executable AI", with its core proposition being "Generic AI doesn't know how you do the work" — what AI lacks is not knowledge, but your judgment framework, evidence preferences, and decision-making order. It transforms expert methods into structured AI Skills, executes analysis, comparison, and evaluation step by step, and outputs deliverable results. The official states that it is suitable for consulting, due diligence, and professional teams where "the method itself has market value".
Who is it for?
- Consulting and due diligence teams that want to distill consultant expertise into reusable methodologies and reduce repetitive work
- Investment banks, law firms or professional service organizations that have a fixed analytical framework and want AI to execute step-by-step
- Knowledge-intensive enterprises that want to package internal methods into diagnostic tools or decision models available to clients
- Team leaders who need to unify the judgment standards of multiple consultants and ensure the consistency of deliverables
Key features
6Structured Reasoning
The official website states that it breaks complex tasks into sequential steps such as reading, comparison, evaluation, judgment, and output generation, allowing the AI to follow the framework rather than act freely.
Evidence-Driven
The official website emphasizes defining inputs and evidence before execution, with outputs citing sources to reduce unfounded conclusions.
Human Approval Points
The official website states that manual approval can be set at key steps, such as having a partner confirm before finalizing risk conclusions.
Traceability
The official website states that the workflow of each step, referenced evidence and reasoning for conclusions are all on record and can be exported for governance or audit purposes.
Model-Agnostic
The official website states that Skills can be exported to environments such as ChatGPT, Claude, and Microsoft Copilot, supporting SKILL.md and MCP formats to avoid binding to a single model.
PII Protection
The official website states that it automatically performs desensitization and pseudonymization processing before sending sensitive information to the model.
How to use Skillsize
- The official website states that it operates by invitation only with a limited number of spots available each month.
- First, you need to submit an application via Request Access and prepare a statement that explains the value of your methodology.
- Use a real client case (such as leadership due diligence) to clarify the judgment criteria, evidence requirements, and approval points, rather than just providing a description of the methodology.
- First, create a Skill to run through the entire process, check if the output matches the client's final delivery format, and then expand it to other scenarios.
- After being exported as SKILL.md or MCP, it can be run in ChatGPT, Claude or Copilot, and the official website states that there is no need to maintain multiple sets of prompts repeatedly.
- When handling customer data, confirm that PII anonymization is enabled and set clear approval criteria at the human review points.
