Practical AI tools designed for daily use

AI only creates value when it can be used confidently, consistently, and repeatedly in real work.

Lydian Stone’s AI build kits are practical, reusable toolsets designed to support specific workflows across investment, strategy, and finance teams. Each kit is shaped around how work is actually done, ensuring outputs are decision-ready rather than illustrative.


The focus is on usefulness, reliability, and fit - not experimentation for its own sake.

Built on frontier models, shaped for real workflows

What an AI build kit includes

Structured prompt templates

Carefully designed prompts that capture required inputs, decision logic, and output formats.

Workflow-specific examples

Sample inputs and outputs shaped to match existing documents, standards, and expectations.

Model configurations or custom GPTs

Tuned environments that reflect the organisation’s tone, structure, and quality thresholds.

Optional custom tools

Web-based or document-integrated tools built where additional control, automation, or fidelity is required.

Guides and usage notes

Clear instructions, guardrails, and checklists to support consistent use across teams.

Designed for consistency and judgement

Each kit:

Structures information clearly
Makes assumptions and reasoning visible
Produces outputs that can be reviewed, challenged, and refined
Fits naturally into existing decision and approval processes

This ensures AI accelerates thinking without obscuring responsibility or accountability.

Integrated into existing systems

Outputs are generated directly into:

Investment memos and papers
IC and Board decks
Research summaries and reports
Planning, performance, and commentary documents

This avoids manual copy-and-paste and reduces reformatting effort, helping teams move from input to decision more quickly.

From tools to capability

AI build kits are not delivered as static artefacts.


They are tested against live work, refined based on feedback, and adjusted as workflows evolve. Over time, they form a coherent library of trusted tools that support consistent execution across roles, teams, and cycles.
