Everything a PM needs. Nothing a PM doesn't.

Purpose-built features that turn scattered product context into delivery-ready artifacts. No bloat. No generic AI chat.

Core capabilities

Talk to your users without scheduling a call

Create evidence-based personas from your interviews, then ask them about pain points, objections, and MVP adoption likelihood.

Generate user personas and have AI-simulated conversations grounded in real interview data.

10 interviews analyzed before your standup

Upload transcripts or audio. Get auto-clustered pain points with severity scores, supporting quotes, and confidence intervals.

Automatically synthesize themes and evidence across dozens of interviews in minutes.

Every claim traced to evidence

Unlike ChatGPT or Claude, every AI output includes inline citations back to your source documents. No hallucination. No hand-waving.

Every paragraph in your PRD links to the exact user quote, ticket, or data point it came from.

The right AI model, automatically

Smart Model Routing picks the optimal model (Claude, GPT-4o, Gemini) based on your query type. Better quality. Lower cost.

Simple questions use fast models. Deep analysis uses powerful ones. You save tokens without thinking about it.

From rough notes to structured PRD in minutes

20+ templates: PRD, Persona, JTBD, Competitive Analysis, Impact/Effort Matrix, Tech Spec, OKR/KPI, and more.

Choose a template, attach your context, and get a structured output in the format your team expects.

Your product memory never forgets

1Brain remembers your roadmap, decisions, and trade-offs across every session. No re-explaining your product.

Context persists across conversations. Your AI copilot knows your product as well as you do.
