## 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

## Lemon

Lemon is a desktop AI assistant built around a simple observation: most people speak far faster than they can type. Instead of adding another chat interface, Lemon lives in a small notch at the top of your screen and works at operating-system level, which means it can type into whatever text field you currently have focused — an AI chat window, an email composer, a Slack thread, a CRM note or a document editor.

The core feature is voice-to-prompt. Hold a hotkey, talk through what you actually want — including the messy parts — and Lemon shapes it into a structured prompt with a clear goal, context and constraints. For everyday writing, it also offers straightforward dictation: your exact words appear in a fraction of the typing time, with "ums", repetition and dead ends automatically removed.

Lemon is available for macOS (13 and above) and Windows and is free to start with no credit card required. The company positions it as a speed layer for knowledge work rather than a replacement for AI assistants themselves — you keep using ChatGPT, Claude or Cursor, and Lemon simply gets your intent into them faster and more clearly.

**Pricing & Plans:** Lemon offers a free starting tier with no credit card required, plus paid plans that raise usage limits. Exact plan prices and allowances are listed on the official website.

- **Voice to structured prompt:** Hold a hotkey, speak naturally, and get a well-structured prompt — with goal, context and constraints — typed directly into your active text field.
- **Fast dictation with filler cleanup:** Dictate five times faster than you type while Lemon cleans up filler words and false starts, leaving only your intended words.
- **Writing in every app:** Emails, Slack messages, team updates and notes are rewritten in your tone and matched to the surrounding thread.
- **OS-level, no plugins:** Lemon sits in a notch at the top of your screen on macOS and Windows and works with Claude, ChatGPT, Cursor, Gmail, Slack, Notion, Outlook, Teams and more.
- **Handles messy thinking:** You can ramble, backtrack and change your mind mid-sentence; Lemon still extracts the intent and produces a usable prompt.

**Strengths:** Works system-wide in every app with a text field — no integrations or plugins to configure; Turns rambling spoken thoughts into structured, usable prompts; Dictation mode is markedly faster than typing and automatically removes filler words; Available on both macOS and Windows with a fast two-minute setup

**Limitations:** Requires a consistent microphone setup; noisy environments hurt accuracy; Desktop-only (macOS 13+ and Windows); Free tier usage limits apply, and automated "prompt polishing" removes some manual control
