## David

David is distributed as a Chrome extension and targets a narrow, practical annoyance: filling in the same kinds of web forms again and again. Instead of typing your name, address, preferences and survey answers field by field, the extension detects the inputs on the page and completes them for you.

The publisher describes it as learning and adapting over time, so the more often you use it, the closer its fills get to what you would have typed yourself. Customisable settings give you control over how aggressive the automation is, which matters when a mistake on a checkout page is more costly than a mistake on a survey.

It is a small, single-purpose tool with a very modest install base and English-only interface. If your browser use involves a lot of registration and data-entry screens, it is worth a look; if you rarely touch web forms, there is little here for you.

**Pricing & Plans:** Listed in the Chrome Web Store as freemium. The extension is a free install; no separate subscription price or official pricing page is published.

- **Automatic field completion:** Detects form fields on the page and populates them automatically rather than making you tab through and type each one.
- **Preference learning:** The extension adapts to your preferences and typical answers, so repeated fills need less correction.
- **Customisable behaviour:** Settings let you decide how much the extension does on its own versus how much you review before submitting.
- **Works across registrations and surveys:** Covers registrations, surveys, checkouts and other multi-field web forms rather than one specific site.
- **Lightweight footprint:** The extension is tiny, so it adds negligible browser overhead.

**Strengths:** Very small download (about 61 KB) with minimal browser overhead; Handles the repetitive part of registrations, surveys and checkout forms; Adapts to your preferences so fills improve over time; Settings let you keep control over what it fills automatically

**Limitations:** Only around 20 installs and zero ratings, so maturity is unproven; English-only interface; Stores and reads page content to function, which some users will weigh carefully; No published pricing page or dedicated website, only the store listing

## Instafill.ai

Instafill.ai tackles one of the most tedious parts of paperwork: filling out the same PDF and Word forms over and over. You upload a flat PDF or a .docx template, and the platform's LLM-based extraction engine detects the fields, groups related inputs intelligently, and pulls answers from source documents, emails, or saved profiles. The result is returned in roughly 25 to 60 seconds per form, with a visual editor for reviewing and correcting values before export.

The platform stresses explainability and control. Every filled field can show its source and reasoning, style-replication learns from your corrections so future forms match your formatting, and version-aware prefilling extracts values from an older copy of a form to populate a new one. Large batches are handled with concurrent field processing, and tables and repeating row structures get dedicated structured-data handling.

Security is positioned for regulated industries: field-level AES encryption at rest, multi-provider authenticated login with optional two-factor authentication, complete multi-tenant workspace isolation, and a choice of data residency region. Instafill also ships developer-facing tooling, including a REST API, an MCP server for Claude and ChatGPT, and native n8n and Zapier integrations.

**Pricing & Plans:** Instafill.ai offers a free entry point (sign-up to try), paid subscription tiers, and enterprise plans that require contacting sales. Specific per-plan rates are not published on the homepage, so check the pricing page for current figures.

- **LLM-based field extraction:** Automatically detects and maps every field in a flat PDF or Word form, using semantic understanding rather than rigid templates.
- **Explainable fill results:** Each filled field can display its source and the reasoning behind the value, making verification fast and auditable.
- **Batch and table processing:** Runs concurrent parallel field filling and handles structured row data, so multi-form packets and repeating tables are completed together.
- **Claude and ChatGPT MCP integration:** An MCP server lets you fill PDFs from inside Claude Desktop, Code, or ChatGPT, plus n8n and Zapier automations for wider workflows.
- **Security and data residency:** Field-level AES encryption at rest, optional two-factor authentication, workspace isolation, and a choice of data residency region.

**Strengths:** Works on flat documents, not just already-fillable PDFs; Reports explainable field-level sources for easy review; Batch mode and table handling suit high-volume paperwork; MCP server plus n8n and Zapier integrations fit existing automations

**Limitations:** Detailed per-tier pricing is not shown on the landing page; Accuracy still benefits from human review on complex or ambiguous forms; No native mobile app experience is highlighted; Advanced workflow features target teams rather than casual single-form users
