## Eraser

Eraser is a technical design platform aimed at the people who document architecture: enterprise architects, DevOps and platform engineers, consultants, and software teams. The core promise is speed without sloppiness, so instead of dragging boxes for hours you describe the system or point Eraser at a source of truth such as code, a cloud account, a CMDB, or a spreadsheet, and it produces a diagram that already follows sensible layout rules.

Beyond static images, Eraser supports interactive maps that zoom from a company-wide view down into a single service, guided explainers that walk teammates through a system, and AI documents for design docs and technical documentation. Team governance features such as shared style presets, naming rules, and reference architectures keep output consistent as more people create diagrams. An open-source agent toolkit and MCP server let tools like Claude, Cursor, and ChatGPT create, search, and export diagrams programmatically.

Prices are organized in tiers that include a free entry point, paid plans, and enterprise agreements, with multi-tenant, single-tenant, and self-hosted deployment options for larger organizations. Security posture includes SOC 2 Type 2 certification and SAML SSO.

**Pricing & Plans:** Freemium with paid plans and custom enterprise pricing. A free tier and free tools such as DiagramGPT are available, while paid individual and team plans plus enterprise agreements cover advanced governance, security, and deployment options; check the pricing page for current rates.

- **AI diagram generation:** 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.
- **Maps from live systems:** 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.
- **Diagram-as-code integrations:** Paste code or connect private and public Git repositories, Confluence, Notion, VS Code, and GitHub to keep diagrams grounded in actual implementation.
- **Open-source agent toolkit and MCP server:** 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.
- **Team style governance:** Apply presets, naming and notation rules, and reference architectures so every teammate's diagram ships on-brand and consistent.

**Strengths:** Turns prompts, code, and files into properly laid-out diagrams instead of raw box-and-arrow output; Interactive maps and explainers make complex systems understandable to non-architects; MCP server and open-source toolkit fit agent-driven and self-hosted workflows; Enterprise controls such as SSO, SAML, and SOC 2 Type 2 certification

**Limitations:** Heaviest value comes with team and governance features that need setup; Advanced mapping and self-hosted deployment are aimed at larger organizations rather than solo users

## WriteMapper 4

WriteMapper 4 is built around a single, memorable idea: writing and thinking are the same activity, so the tool should let you see your thinking before you commit it to paragraphs. Instead of starting from a blank page, you build a mind map — called a WriteMap — where each idea is a node. That map becomes your outline, and expanding the nodes gives you the draft, all without losing the bird's-eye view of your argument.

The app is a native desktop program for macOS and Windows, available with a one-time-fee license and a fully featured 7-day trial. It is positioned as a private, offline-friendly workspace: WriteMaps live on your disk as regular files, autosave and snapshots protect your work, and the publisher states there is no data harvesting or invasive tracking.

AI is a supporting act rather than the headline. An optional 'Ask AI' feature appears at each phase — ideation, outlining and drafting — so you can kickstart a stalled section or sharpen your structure, but the core mind-map workflow stands on its own. For content writers, authors, academics and anyone who thinks in branches rather than bullets, WriteMapper offers a coherent pipeline from messy notes to exported Word, Markdown or PDF documents.

**Pricing & Plans:** WriteMapper 4 uses a one-time-fee license model: pay once for lifetime access to the current major version, with a fully featured 7-day free trial (no credit card required) available before purchase. Optional AI features and multi-device add-on licenses are sold separately. Exact prices are listed in the official store.

- **Mind-map to outline workflow:** Capture ideas as nodes on a visual WriteMap and watch them convert into a structured outline you can expand into full text.
- **Ask AI at every stage:** An optional Ask AI assistant helps you generate ideas, structure an outline and flesh out paragraphs during writing.
- **Distraction-free node writing:** Double-click any node to write distraction-free with rich-text formatting, Markdown syntax, spellcheck, autocorrect and image support.
- **One-click export to many formats:** Automatically compile your WriteMap into a polished draft and export to Markdown, HTML, OPML, DOCX, TXT, RTF, PDF or PNG, or copy to clipboard.
- **Built for large documents:** Autosave, snapshots and automatic backups, a dark mode, quick search across all nodes, drag-and-drop organization and offline privacy by design.
- **Productivity extras:** Use keyboard shortcuts, dictation on macOS and Windows, color tags and task status markers to move quickly through long projects.

**Strengths:** Turns messy brainstorming into a structured outline without leaving one app; Genuine one-time-fee model instead of a mandatory subscription; Strong export coverage (Markdown, HTML, OPML, DOCX, TXT, RTF, PDF, PNG); Private and offline by design, with autosave and snapshots

**Limitations:** Desktop-only (macOS and Windows) with no browser or web version for quick access; One-time license cost per major version; there is no free forever tier beyond the 7-day trial; Mind-map-first workflow takes some adjustment if you prefer linear, plain-text writing; AI-assisted features require a separate AI add-on/usage beyond the base license
