1Brain is an AI-native workspace purpose-built for product managers. It captures context from PM tools (Jira, Linear, Confluence, Notion, Slack, Figma) via a Chrome Extension, maintains persistent product memory across sessions, and generates evidence-based PRDs, personas, specs, and roadmaps in minutes. Every AI output includes inline citations back to your source documents.

How is 1Brain different from ChatGPT or Claude?

ChatGPT and Claude are general-purpose AI tools that reset context every session and produce output without citations. 1Brain is purpose-built for product managers: it captures context automatically from 25+ PM tools, maintains persistent product memory across all sessions, generates structured artifacts using 20+ PM-specific templates, and every response includes inline citations to your actual data. 1Brain is the difference between an AI that knows your product and one you have to re-brief every day.

How does 1Brain compare to NotebookLM?

NotebookLM is a document research tool. 1Brain is a complete PM workflow platform. 1Brain goes beyond document Q&A: it integrates with Jira, Linear, and Slack to capture live context, generates structured PM artifacts (PRDs, personas, competitive analyses) using 20+ templates, maintains product memory across sessions, and supports multi-user team workspaces. NotebookLM cannot generate delivery-ready PM artifacts or push to engineering tools.

Can I use 1Brain for user interview analysis?

Yes. Upload audio files or transcripts (up to 20 at a time). 1Brain transcribes audio automatically, clusters pain points with severity ratings (high/medium/low), extracts supporting quotes with confidence scores, and generates a structured interview analysis in minutes. Product managers report this takes minutes instead of an afternoon.

What AI models does 1Brain support?

1Brain supports Claude (Haiku, Sonnet, Opus) by Anthropic, GPT-4o and GPT-5 by OpenAI, and Gemini 2.5 Pro by Google. Smart Model Routing automatically selects the optimal model for each query — fast models for simple questions, powerful models for complex analysis — reducing cost while maintaining quality.

How does the evidence citation system work?

Every AI-generated response in 1Brain includes inline citations [1], [2] etc., linked directly to the source documents, interview quotes, or Jira tickets that support each claim. This eliminates hallucination — every statement in your PRD is traceable to real user data. Unlike ChatGPT or Claude, 1Brain cannot generate unsourced claims when your documents are loaded.

Does 1Brain support my existing PM tools?

1Brain integrates with 25+ PM tools including Jira, Linear, GitHub, Confluence, Notion, Slack, Figma, Google Workspace (Docs, Drive, Calendar), Miro, Productboard, and Zendesk. The Chrome Extension lets you capture context from any web-based tool in one click without copy-pasting.

Is 1Brain safe for enterprise data?

Yes. 1Brain uses zero-retention AI providers (your data is never used to train AI models), AES-256 encryption, workspace-level Row Level Security, and automatic PII redaction before content reaches AI providers. BYOK (Bring Your Own Keys) is supported on all plans for organizations that require maximum data control.

How much does 1Brain cost?

Free is $0 with 1K AI requests per month. Starter is $6.99/month. Pro is $14.99/month with first month at $1.99 and includes all integrations and Smart Model Routing. Ultra is $29.99/month. Annual billing saves approximately 20%.

What are Persona Copilots?

Persona Copilots are evidence-based user personas generated from your actual interview data. Once created, you can have AI-simulated conversations with them — ask about pain points, objections to your product, likelihood of MVP adoption, and more. Every response is grounded in real user quotes so you get realistic, data-backed feedback without scheduling another customer call.

Pain points

Every PM hits the same walls

Context scattered, evidence missing, and specs that teams do not trust.

You spend the first 20 minutes of every AI session re-briefing ChatGPT on your product

Every session starts from zero. By the time the AI understands your context, half the meeting is over.

Your PRDs cite user research that lives in Notion, but the AI you use has never seen it

Context is scattered across 7 tools. Decisions get made on vibes because the evidence is buried three tabs away.

AI-generated docs sound confident but have no connection to your actual user research

Your engineering team pushes back because the spec cites nothing. You spend hours adding the evidence that should have been there from the start.

Workflow

From scattered context to shipped PRD in 3 steps

Connect your sources once. 1Brain remembers context and generates evidence-backed artifacts.

Capture

Upload documents or connect integrations to bring all product context into one workspace.

Chat

Talk to AI with selected sources and get grounded answers with evidence-linked citations.

Ship

Save strong outputs to Artifacts and continue refining decisions with your team.

Core workflow

Context memory

Your context carries across every conversation

1Brain keeps roadmap decisions, prior artifacts, and source evidence in memory, so you do not restart from zero every session.

No re-briefing loop in daily PM work.

Comparison

Why not just use ChatGPT?

General AI is strong for ad-hoc tasks. PM workflows need grounded context, structure, and traceability.

ChatGPT

•Re-brief context every session
•No source traceability by default
•Generic output shape for PM docs
•No PM-native workspace flow

1Brain

✓Persistent product memory across sessions
✓Inline evidence citations in generated output
✓Structured PRD/spec templates for delivery
✓Shared PM workspace with handoff-ready artifacts
