# GRTforms

> GRTforms is a hosted form builder by GrtLabs Inc.. Create responsive forms with a drag-and-drop builder, collect submissions, export CSV / Excel / PDF, and automate with a REST API, signed webhooks, and an MCP server. Sign in with email and password, or request an email sign-in link.

## Docs

- [Developer API](https://grtforms.com/developers): REST API v1, authentication, curl examples, and webhooks
- [MCP server](https://grtforms.com/developers/mcp): Connect Claude Desktop or Cursor with a scoped API key
- [OpenAPI 3.1](https://grtforms.com/api/v1/openapi): Machine-readable spec for the public REST API
- [Hidden fields and per-field CSS](https://grtforms.com/docs/hidden-fields): Prefill UTM and other values respondents never see. Target each field with a CSS ID or class. Wrappers already include grt-field and grt-field--{type}. Hide the public title, description, or the whole header.
- [Select submissions to export or delete](https://grtforms.com/docs/submissions-selection): Check rows, select the page, or select every match. The selection stays as you page. Export only those rows to Excel, CSV, or PDF, or delete them after a confirm. With nothing selected, export follows your current filters. Exports are logged.
- [IP blocks and abuse alerts](https://grtforms.com/docs/security): Block IPv4, IPv6, or CIDR ranges (including IPv6 /64) per form or across your account. Abuse detection watches spikes, repeat IPs, duplicate payloads, and honeypot hits, then sends one alert and a 30-minute digest with actions to block, turn on CAPTCHA, pause, or ignore.
- [Form access controls](https://grtforms.com/docs/access-controls): Pause a form, cap how many real entries it accepts, schedule open and close times, or require a password. Visitors see a closed or unlock page; submit is blocked on the server.
- [Cloudflare Turnstile CAPTCHA](https://grtforms.com/docs/turnstile): Turnstile on sign-up, sign-in, and public forms. Require it on any form. Verification runs on the server, shows a clear error instead of hanging, and resets so people can try again.
- [Conditional logic](https://grtforms.com/docs/logic): Show or hide fields, skip pages, and choose confirmation copy from answers. Rules stay attached to field ids when you reorder.
- [Calculated fields](https://grtforms.com/docs/calculations): Read-only totals, scores, and quotes from formulas such as {quantity} * {unit_price}. The server recomputes the value on submit.
- [Multi-step forms](https://grtforms.com/docs/multi-step): Insert a page break to split a form into steps. Respondents move Next / Back. Preview and logic skip still work across pages.
- [Signatures](https://grtforms.com/docs/signatures): Drawn or typed signatures with an audit trail owners can export. This is not legal advice.
- [PDF export](https://grtforms.com/docs/pdf-export): Export selected or filtered submissions as PDF, or download one branded PDF per entry. Included on Free.
- [File uploads](https://grtforms.com/docs/file-uploads): File uploads with type and size limits on hosted forms.
- [Ask AI in the builder](https://grtforms.com/docs/ai-refine): Chat-edit an existing form. The model returns a structured patch you can Apply, Discard, or Undo. Submissions are never sent to the AI.
- [Builder Preview](https://grtforms.com/docs/form-preview): Walk through the respondent form, including unsaved drafts, without publishing or storing a submission.
- [Drag and drop fields](https://grtforms.com/docs/drag-and-drop): Drag a field type onto an exact spot, drop beside a half-width field to pair half | half, reorder with a handle or keyboard, and undo without breaking logic.
- [Guest AI builder](https://grtforms.com/docs/guest-ai-builder): Generate and refine a form at /try without an account. The draft stays in this browser until you sign up to save it.
