Frequently asked questions

What makes Moss a notes app built for product managers?
Product management lives in documents: PRDs, priority frameworks, competitive analyses, meeting notes, roadmap rationale. Most tools force you to scatter this work across Google Docs, spreadsheets, and Notion. Moss brings it into one workspace where every note is a markdown file on your computer. The AI agent researches, drafts, and organizes inside the document, not in a separate chat window. Ask it to score your feature list by impact, research a competitor's pricing, or draft a PRD section. The thinking and the artifact stay in the same place.
How can Moss help with priority frameworks and feature triage?
Priority frameworks often start as spreadsheets, but the reasoning behind each score lives in your head or scattered across Slack threads. Moss lets you build priority frameworks directly in your notes with inline formulas. Score features on impact, effort, and confidence — the formulas calculate weighted rankings right in the document. More importantly, the reasoning is right there too: the paragraph above the formula explains why you scored mobile onboarding a 9 on impact. When stakeholders question the priority order, you can point to a single document that shows both the score and the thinking. The AI agent can help too: ask it to pull usage data context, summarize customer feedback themes, or draft a RICE score rationale. Your triage document becomes a living artifact, not a static spreadsheet disconnected from the decisions it informs.
Can Moss help me build and maintain a product knowledge base?
Every PM accumulates a personal knowledge base — competitive notes, customer interview summaries, architectural decisions, feature rationale, onboarding observations. The problem is keeping it organized and findable. Moss supports wiki-style note links: type [[Note Title]] to connect related documents. Link your competitive analysis to the PRD it influenced. Connect customer interview notes to the feature requests they surfaced. Build a decision log that references the specs and data behind each call. Moss also organizes notes automatically — tagging related content and surfacing connections without manual filing. Over time, your product knowledge base becomes navigable by topic, by decision, by customer theme. When someone asks "why did we deprioritize that feature?", you can trace the answer through linked notes instead of searching Slack history.
How does Moss help with competitive research and market analysis?
Ask the AI agent to research a competitor's recent launches, summarize their pricing changes, or compare feature sets across three competitors. It searches the web and writes findings directly into your note with sources included. You stay in the document, editing and annotating as the research comes in. The result is a competitive analysis that's written, sourced, and connected to the rest of your product notes. Link it to the PRD where the competitive insight matters, and the context stays connected.
Can I turn meeting notes into decisions and action items in Moss?
The gap between meeting notes and action is where most product decisions get lost. You write notes during the meeting, then the document sits in a folder while the actual decisions get communicated through Slack or remembered imperfectly. Moss closes that gap. Take meeting notes in a Moss document, then use the AI agent to extract decisions, surface open questions, and draft follow-up items — all inline. Leave an inline comment on the section about the API migration timeline to flag it for next week's discussion. Link the meeting note to the relevant PRD so the decision context is always traceable. The meeting note becomes a working document, not an artifact. And because it's a markdown file on your computer, you can share it through whatever channel your team already uses.
Does Moss support data analysis and charts for product decisions?
Product managers regularly need lightweight data analysis inside their documents: calculating retention rates, comparing launch metrics, visualizing a trend across quarters. You don't need a full BI tool for this — you need numbers next to the narrative they support. Moss includes inline formulas and charts. Run calculations on product metrics directly in your note. Build a bar chart comparing feature adoption rates. Generate a line graph showing weekly active users over time. The analysis lives in the same document as the product narrative, not in a separate spreadsheet you have to screenshot and paste in. The AI agent can help too: ask it to calculate a percentage change, summarize a dataset, or build a chart from figures you paste in. The quantitative analysis stays connected to the qualitative thinking.
How is Moss different from Notion for product management?
Notion is a team platform where you build the system: databases, views, templates, integrations. Moss is a thinking tool where the system builds itself. Every note is a local markdown file. The AI agent handles organizing, tagging, and linking related documents. You don't maintain templates or configure views. Moss also includes inline formulas, charts, and web research natively. If your PM workflow is primarily about clear thinking and good writing, Moss gives you that without the configuration overhead.
Can I write PRDs and product specs in Moss?
Yes, and the workflow is better than a standalone doc editor. Start with a rough outline, then ask the AI agent to expand sections: it can draft user stories from a brief description, research technical constraints, or flesh out edge cases you listed as bullets. Use inline comments to leave review notes for yourself or flag sections that need stakeholder input. Add formulas to calculate projected impact metrics. Link the PRD to related competitive research, customer interview notes, and decision logs. The result is a PRD that's connected to the thinking behind it, not a standalone document floating in a folder. And because Moss notes are plain markdown files, you can share the spec through git, paste it into a wiki, or open it in any other tool that reads markdown.
Is Moss local-first? Where do my product notes live?
Every note is a file on your computer. Nothing is sent to a cloud server. No company database stores your product plans. If you use the AI agent, queries are processed by Claude (Anthropic) and nothing is retained for training. Your roadmap stays on your machine. No account required, no vendor lock-in.
Does Moss work offline?
Yes. Notes are files on your computer, so reading, writing, and searching all work without a connection. The AI agent needs internet when you invoke it, but everything else works fully offline. No login required, no sync delay.
Can I use Moss alongside tools like Linear, Jira, or Figma?
Moss is a thinking tool, not a project management tool. It complements your execution stack rather than replacing it. Write the PRD in Moss, then reference it from Linear tickets. Draft the competitive analysis in Moss, link it in your Jira epic. Keep your priority framework and decision log in Moss while tasks flow through whatever tracker your team uses. Because notes are plain markdown files, they're easy to share: paste into a wiki, commit to a git repo, or link from any tool that accepts URLs or file paths. Moss handles the thinking and writing side of product management; Linear and Jira handle the execution tracking.
Does Moss train AI on my product notes or roadmap?
No. The AI agent processes requests using Claude (Anthropic) and nothing is retained for model training. Your competitive intelligence, roadmap priorities, and strategic documents stay private. If you connect Claude Code, the same protections apply.
What happens to my notes if I stop using Moss?
Nothing changes. Your notes are standard markdown files on your hard drive. Stop using Moss and open them in VS Code, Obsidian, iA Writer, or any text editor. There's no proprietary format, no export step, and no data held hostage. Your PRDs, competitive analyses, meeting notes, and decision logs are all just .md files. This portability is especially important for product work — your thinking artifacts should outlast any particular tool.
