Pre-build planning

Your project, fully planned before you write line one.

Example outputProject: personal document workspace

1. Discovery question
Who can access a project’s documents?
2. Your answer → planning decision
“Just the project owner. No sharing in the MVP.”
Decision: Require sign-in and check project ownership before every document request.

3. Generated documentation

docs/AUTH.md

## Document access

- Only the signed-in project owner can
  read or edit project documents.
- Verify ownership on every request.
- Sharing is out of scope for the MVP.

The problem

AI coding agents fail when planning is missing.

Every undocumented decision — database schema, auth strategy, deployment target — becomes a broken build discovered mid-sprint. DevDocs AI surfaces every decision before development begins.

✕ Without DevDocs AI

Build me a SaaS app with user auth,
a dashboard, and Stripe payments.

✕ No schema — the agent guesses and gets it wrong
✕ Auth strategy undecided — JWT vs sessions resolved at random
✕ Stripe webhooks break because the strategy was never defined
✕ Three days of rework. Significant token waste.

✓ With DevDocs AI

docs/README.md → 10 files loaded
Full architectural context present.

✓ Schema designed and indexed before a table is created
✓ Auth documented with provider, session, and RBAC decisions
✓ Stripe webhook strategy defined in ENV-STRATEGY.md
✓ Coding agent begins with documented project decisions.

How it works

Four steps between your idea
and an implementation-ready plan.

01 — Interview

The AI asks every question you'd skip.

Targeted questions across 10 planning domains. Architecture, database, auth, testing, deployment, and more. Every question is the one a senior developer would ask before writing a line of code.

02 — Recommend

Opinionated, not neutral.

Based on your constraints — team size, timeline, budget, scale — the AI recommends architecture with justification. It argues for a monolith over microservices when that's the right call.

03 — Generate

Relevant domains, documented.

DevDocs generates the documentation domains relevant to your project type. Each follows a consistent markdown format and remains editable before export.

04 — Export & Build

Drop in. Point. Build.

Download the generated documentation bundle as a ZIP. Drop the docs/ folder into your project root and give your coding agent the decisions captured during the interview.

The output

Ten supported domains.
Your project gets the relevant set.

PLANNING.md

Project scope, MVP definition, success metrics, timeline

ARCHITECTURE.md

Tech stack decisions, architecture decision records, component responsibilities

DATABASE.md

Schema design, migration strategy, indexing plan, soft delete policy

API-CONTRACTS.md

Endpoint definitions, request/response shapes, authentication per route

ENV-STRATEGY.md

Environment list, secrets management, CI/CD gate definitions

AUTH.md

Auth provider, session strategy, token storage, RBAC model

TESTING.md

Testing pyramid, tool choices, coverage targets, CI integration

MONITORING.md

Four golden signals, alert thresholds, error tracking, health checks

FRONTEND.md

Design tokens, component architecture, state management pattern, a11y targets

DEPLOYMENT.md

Hosting platform, deployment method, rollback strategy, scaling triggers

Every generated file is editable in-app before ZIP export.
