Origo

Origo follows a modern serverless architecture optimized for speed and cost efficiency. The Next.js frontend handles both the guided input flow and brief rendering, with server-side generation for shared brief pages.

The AI pipeline uses Anthropic's Claude API via the Vercel AI SDK for streaming responses — users see their brief being generated in real time rather than waiting for a full response. Internationalization is built in from day one (FR/EN), with locale-aware routing and translated UI throughout.

Key Decisions

• Streaming generation — Briefs are generated using Claude with streaming enabled. Users see content appear progressively, which dramatically improves perceived performance and engagement.
• Local-first storage — Brief data is persisted client-side, reducing server costs and giving users full control of their data. No account required for basic usage.
• Shareable links — Each brief generates a unique URL that clients can view without creating an account, reducing friction in the handoff process.
• Bilingual by default — Full FR/EN support with Next.js i18n routing, reflecting our France-based market while targeting international clients.
