Technical Specification Generator
Write structured technical specifications, RFCs, design documents, and Architecture Decision Records that align engineering teams and drive clear implementation.
Your Technical Specification Generator results will appear here
Как использовать Technical Specification Generator
- Describe the feature, system change, or technical decision in detail — include the problem, current state, and your proposed approach.
- Select the document type: RFC for proposals needing consensus, Design Doc for implementation plans, ADR for recording architectural decisions.
- Choose your audience to calibrate the technical depth — engineers get deep implementation detail, stakeholders get business impact summaries.
- Set the detail level: 'Implementation-ready' generates specs specific enough for engineers to start coding from.

Советы для достижения лучших результатов
- Include constraints in your description — budget, timeline, team size, existing tech stack — so the spec accounts for real-world limitations.
- For the 'Alternatives Considered' section to be useful, mention any approaches you have already thought about and why you are leaning toward your proposed solution.
- Request 'Implementation-ready' detail level when you want the spec to serve as an engineering task breakdown — it will include specific API endpoints, database queries, and code structure.
- The 'Open Questions' section is valuable for asynchronous review — list specific decisions you need reviewer input on.
Часто задаваемые вопросы
What is the difference between an RFC and a Design Doc?
An RFC (Request for Comments) is a proposal seeking consensus — it presents a problem and proposed solution for team review before committing to an approach. A Design Doc is a detailed implementation plan for an already-agreed approach — it focuses on how to build it, not whether to build it.
What is an ADR?
An Architecture Decision Record (ADR) documents a significant architectural decision — the context, the decision made, and the consequences (both positive and negative). ADRs create a searchable history of why your system is built the way it is, invaluable for future team members.
How detailed should the implementation plan be?
At 'High-level': architecture overview with component responsibilities. At 'Detailed': data models, API contracts, and sequence diagrams. At 'Implementation-ready': specific enough to create Jira tickets — endpoints, database migrations, feature flags, and test plans.
Should I include diagrams?
The generator includes ASCII diagrams for data flow, system architecture, and sequence diagrams. These render in any text editor or Markdown viewer. For formal presentations, you can recreate them in tools like Mermaid, draw.io, or Excalidraw.
How long should a technical spec be?
A Technical Brief: 1-2 pages. An ADR: 1 page. A Design Doc: 3-8 pages depending on complexity. An RFC: 5-15 pages for major architectural changes. The generator calibrates length to your selected detail level.
Can stakeholders understand the generated spec?
Select 'Stakeholders' or 'All Audiences' as the target audience. The generator will lead with business context and impact, use plain language for technical concepts, and include a TL;DR summary. Technical details are still present but clearly separated.
