## 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

## Riter

Riter has evolved from a UX-copy generator into a focused workspace for people writing a book. The product's core premise is that a good book carries a perspective worth sharing, and that generic or unsupported prose weakens it. Instead of flooding a draft with machine-written filler, Riter aims to draw on what you already know — your ideas, voice and experience — and help you develop that original thinking into a coherent manuscript.

The workspace walks through the whole arc of a book project. You begin by building a foundation from author and book interviews, spoken thoughts and selected writing. From there, assistance with outlines, chapters and research helps you develop an argument, a story or the frameworks of a technical book, with every suggested change left for you to review. A chapter workspace puts notes beside your draft, and you can export a chapter or the whole book to Markdown when you want to take it elsewhere.

Feedback in the preview is deliberately honest about its own limits. Voice, originality, accuracy and continuity each have a separate state, and some read as unavailable rather than pretending to be precise measurements. The preview does not compare your draft against your own past writing, and the site states plainly that these checks do not establish authorship, detect plagiarism or verify facts. Under the surface sits an ambitious product vision that includes book design as well as Word and PDF manuscript exports, but the company is explicit that the currently available free writing preview is only a first slice of that larger picture.

**Pricing & Plans:** Riter is listed at a single price of $12 per month or $120 per year with nothing held back behind a higher tier. The site notes that nothing is charged yet during the alpha, and that you will be asked before any charge is made. A free writing preview is available via Google sign-in, with work stored locally in your browser rather than synced to an account.

- **Author-grounded foundation:** Start from author and book interviews, spoken thoughts and selected writing so your manuscript is grounded in your own experience, purpose and intended reader.
- **Chapter-by-chapter development:** Get help shaping outlines, chapters and research trails while keeping every change open to your own review and approval.
- **Drafting and notes workspace:** Work in a browser editor with chapters, notes beside your draft, and a wording review that flags patterns for you to consider.
- **Separate feedback signals:** See separate states for voice, originality, accuracy and continuity, presented honestly as review signals rather than measured scores.
- **Markdown export:** Export a chapter or the entire book to Markdown so you can take your work to other tools or editors.

**Strengths:** Purpose-built for long-form book writing instead of generic content generation; Strong emphasis on keeping the author's own voice and judgement in control; Transparent, honest feedback states that avoid overclaiming precision; Simple single-tier pricing with no feature gating behind expensive plans

**Limitations:** Still in an early alpha phase, and much of the advertised author experience is labeled as product vision rather than shipped functionality; Writing is stored only in the local browser on the device used, with no account-based sync or backup yet; Some feedback states (voice, accuracy, continuity) show as unavailable and do not convert into real measurements; No team collaboration or cloud export pipeline is fully delivered beyond Markdown chapter export in the preview
