## 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

## Harold

Harold is built on a simple premise: most document tools extract text, but few make that text trustworthy. Harold extracts data from invoices, receipts, purchase orders and statements, then applies a rules engine to validate it — checking that totals match subtotals and VAT, that supplier IDs are correct and that every line item adds up — before push to your systems.

The key differentiator is where Harold catches problems. Instead of silently passing half-extracted documents downstream, it flags or fixes issues at the point of entry. A supplier mapping feature lets you map document aliases to your internal supplier IDs once and reuse that mapping forever, and output templates let you shape the export to exactly what your ERP, finance team or Zapier flow expects.

Harold connects via Zapier or a ready-to-import file, and supports newer and legacy ERPs including Sage, Pegasus, SYSPRO and WinMan, as well as spreadsheets and inbox ingestion. Pricing is simple and predictable with a £19/month Founder rate, a £29/month Standard plan, a £79/month Premium tier and an Enterprise option for high-volume processing.

**Pricing & Plans:** Harold uses simple tiered subscriptions: a free start to train your first document, a limited Founder rate at £19/month, Standard at £29/month, Premium at £79/month and Enterprise at £149/month, each with set monthly extraction and automation limits.

- **Document extraction:** AI pulls headers, totals, line items and references from invoices, receipts, purchase orders and statements into structured data.
- **Rules validation engine:** IF checks, formulas and conditional logic catch wrong totals, missing fields and bad supplier IDs, or transform data on the fly.
- **Supplier mapping:** Map any supplier alias on a document to your internal supplier ID once, and Harold applies it automatically from then on.
- **Output templates:** Shape exports to match your ERP, finance team or Zapier flow with CSV, Excel, JSON and webhook output templates.
- **ERP and Zapier integrations:** Connect via Zapier or a ready-to-import file to send clean data into new and legacy ERPs, accounting tools, Excel or Google Sheets.

**Strengths:** Validates data before it reaches accounting systems, not just extracts it; Works with both modern and legacy ERPs plus spreadsheets and Zapier; Supplier mapping and reusable output templates cut repetitive setup; Live pricing and a free way to test with your own documents

**Limitations:** Priced in GBP, which may not suit all international buyers; Document box and automation limits rise only with higher tiers; Setup requires training documents per supplier for best accuracy; No self-serve enterprise features without contacting sales
