# DevSpeak | Stop explaining. Start communicating.

> DevSpeak is an AI-powered technical translation engine that transforms informal stakeholder requirements into formal, audience-specific technical specifications. It serves development teams, technical leads, and engineering managers who need to communicate requirements precisely across different technical roles and seniority levels.

## Key Capabilities

DevSpeak translates informal requirements into five audience-specific formats: Junior Dev, Senior Dev, Tech Lead, SRE, and Data Engineer. Output formats include Technical Spec, Jira Tickets, API Design, RFC, Data Model, Prompt Optimization, and General Optimize. Five technical contexts are supported: Backend, Frontend, Mobile, Data/ML, and DevOps. File attachments (PDF, Markdown, plain text, images) are processed via the Gemini Files API with Firebase Storage fallback. Iterative refinement allows teams to apply feedback to previous outputs for targeted revisions.
