## 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

## Typeahead

Typeahead takes a deliberately different approach from chat assistants. Instead of opening a prompt box, waiting for an answer and copying it back, it sits at your cursor as ghost text and finishes what you are already writing. You type the facts, press Tab to accept a suggested phrase, use the right arrow to take a single word, or keep typing to steer a new suggestion. The site frames the contrast directly: ChatGPT writes for you in a generic voice, while Typeahead writes with you in your style.

Under the surface, several features make the suggestions feel personal rather than generic. It learns your phrases, so a line you write often can be re-summoned after two keystrokes, and it recognizes names and terms your Mac's dictionary does not include. Screen context means suggestions match the conversation you are replying to, and clipboard context puts what you just copied one Tab away. Writing styles can be set per app, so Mail can be professional while Messages stays casual, and there are sixteen languages that follow whichever one you type.

The privacy story is the headline: the model runs on your Mac, writing is never sent to a server, and the app works offline after setup. Supported apps include Mail, Messages, Slack, Notion, Chrome, Gmail, Outlook, Google Docs and Word, with more listed. The product is Mac-only for now, and the site offers both a direct download option and a waitlist, along with free writing tools such as a word counter, grammar checker and typing speed test.

**Pricing & Plans:** Typeahead is a paid macOS application. Its website offers a direct 'Get Typeahead' option and a waitlist rather than a published price list, so check the site or the Mac app store listing for current licensing and pricing details.

- **Sentence completion where you already type:** Faint ghost text completes the word or sentence you are typing right at the cursor. Tab accepts the entire suggestion, the right arrow takes just the next word, and Esc dismisses it so you stay in control.
- **Private by design and offline capable:** The model runs on your Mac rather than in the cloud. Typeahead never sends your writing to a server and keeps working offline after setup, which makes it suitable for work email and sensitive documents.
- **Screen and clipboard context:** It reads what is on screen and what you copied to the clipboard, so replies fit the thread you are actually answering rather than being generic filler.
- **Per-app writing styles and your own colour:** Set a voice per app, professional in Mail and friendly in Messages, choose from seven color-blind-safe highlight shades, and tune suggestion timing to instant, balanced or only when you pause.
- **Learns your phrases and shows time saved:** It learns your go-to lines and the way you phrase things, including names and terms your Mac dictionary does not know, so two words can bring back a sentence you write often. Insights shows the time saved, with the site citing up to 30% faster typing.

**Strengths:** Completes your sentences in place, so you never leave the app you are writing in or copy text back from a chatbot; Runs locally on your Mac and never sends your writing to a server, with offline support after setup; Learns your own phrases and personal vocabulary, so suggestions sound like you rather than like a generic model; Screen and clipboard context make replies fit the actual thread or document

**Limitations:** Currently Mac-only, so Windows, Linux, iOS and Android users cannot use it; The site still shows a waitlist alongside 'Get Typeahead', which can suggest availability is being rolled out gradually; Because it only completes text where you already type, it will not draft a long document or research a topic for you the way a chat assistant will; Per-app writing styles and learned phrases take a little setup before the suggestions feel genuinely personal
