## 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

## WriteMyPRD

WriteMyPRD solves a very specific, very common frustration: staring at a blank PRD template. Instead of starting from an empty document, you answer a short form — product name, feature name, a basic overview, a feature list, and any qualitative user feedback you have — and the bot returns a first draft of a Product Requirements Document. It is deliberately built as a starting point, not a finished artifact; the tool itself warns that less input is better, because the goal is to get you moving rather than to over-optimize the prompt.

The generator runs on ChatGPT and was created by the teams behind Olvy (an AI feedback-analysis product) and TheProductFolks, a product-management community. Beyond the web form, there is a Slack bot you can add to your workspace: it introduces itself as your PRD writing assistant, asks what your product does, and helps you kickstart the document inside Slack so the draft lands where your team already talks.

The site also curates external resources for writing better PRDs — step-by-step guides and template collections from Razorpay, Lenny's Newsletter, and Aha! — and links to ProductHooman, a podcast for product builders produced by Olvy. WriteMyPRD is a free, single-purpose utility rather than a full requirements-management platform: there is no database of documents, no stakeholder review workflow, and no version history. You generate a draft, copy it, and continue writing in your own tool.

**Pricing & Plans:** Free to use, with no credit card required. The site lists no paid tiers; WriteMyPRD is a free utility offered by the teams at Olvy and TheProductFolks, with an optional account login and a Slack bot.

- **Form-to-Draft PRD Generation:** Enter your product name, feature name, overview, feature list, and user feedback, then click Generate My PRD to receive a structured draft written by ChatGPT.
- **ChatGPT-Powered Writing:** The generator is built on ChatGPT, so the draft follows recognizable PRD structure and is phrased as editable product-manager prose rather than raw bullet fragments.
- **Slack Bot Assistant:** Add the WriteMyPRD bot to Slack and it will ask what your product does, then help you start the PRD right inside your team's workspace.
- **Sample Requirement Demo:** A 'Try with a sample requirement' button fills the form with an example so you can see the output quality before investing effort in your own input.
- **Curated PRD Resource Library:** Hand-picked guides and template collections from Razorpay, Lenny's Newsletter, and Aha! are linked to help you improve the draft once it is generated.

**Strengths:** Completely free with no signup wall before you can try it; Removes the blank-page barrier in seconds; Slack bot lets you draft inside the tool your team already uses; Companion resource links help you improve the draft rather than leaving you stranded

**Limitations:** Output is only a starting draft; it still needs substantial human editing; Single-purpose utility with no saved document library, review flow, or version history; Quality depends entirely on how clearly you describe the product in a short form
