The AI product manager for your entire team
Turn a sentence, transcript, or notes into a real PRD grounded in your Notion, Linear, GitHub, and Granola context.
A CPO-level review scores each document on strategy, structure, clarity, and completeness, then offers line-level edits you can accept in one click.
Build a clickable prototype straight from a spec, refine elements by pointing, and share a link the same day—or open in v0, Lovable, Bolt, or Cursor.
Pull context from docs, tickets, code, and meetings, then push finished work to Google Docs, Notion, Confluence, Linear, Jira, Slack, and Teams.
AI diagrams and technical design docs built from your code and systems
Generate architecture diagrams, flowcharts, sequence diagrams, and BPMN from a text prompt, code, Terraform, or an uploaded PDF, Word, Excel, PowerPoint, Draw.io, or Visio file.
Build interactive maps that sync with cloud accounts, repositories, and internal catalogs so the picture stays close to the real environment, with drill-down from org level to a single container.
Paste code or connect private and public Git repositories, Confluence, Notion, VS Code, and GitHub to keep diagrams grounded in actual implementation.
Run the agent toolkit in your own infrastructure under an MIT license and let MCP-compatible clients create, search, update, and export diagrams with OAuth or API tokens.

#1
SpecialistAutomatically embeds visual diagrams directly inside text documents, though it lacks Eraser's specialized cloud architecture focus.
#2Provides extensive drag-and-drop shapes and templates for general diagrams, but weaker automated code-to-diagram capabilities than Eraser.

Agentic product management system for customer-driven roadmaps
Combines team whiteboarding, documentation, and diagramming in one platform, but less tailored for automated codebase architecture.
All-in-one AI workspace that unifies projects, docs, search and agents

Free / Open-sourceOpen-source tool specifically tailored for database schema visualization and ER diagrams, but lacks general system documentation features.


Stronger focus on standard Mermaid syntax and code-driven diagrams, but lacks Eraser's native autonomous architecture doc generation.

SpecialistAI code documentation for any codebase, kept current automatically

SpecialistExcellent for turning cloud architecture directly into infrastructure-as-code, but narrower focus compared to general technical documentation.
SpecialistDescribe your system in words, get a diagram you can edit
Great for interactive chat-based diagram editing from URLs and text, but less specialized for deep engineering infrastructure docs.
