Tools to autofill long forms

The problem, in plain words: “I need a tool that can automatically fill lengthy web forms with lots of personal, educational, work, and household information beyond just name, address, email, and password fields.”

Auto Filler fits best.

You want an autofill tool that can automatically complete long web forms using stored details across many categories, not just basic identity fields.

What fits

Auto Fillerstrong · 86

It’s an LLM-powered Chrome extension built specifically to scan and semantically match many web form fields (beyond just name/address/password), then fill them using locally stored personal information. It also supports managing supporting documents (IDs, diplomas, certificates, photos) by category, which aligns well with lengthy application forms that require more than basic contact data.

Best for: Automatically filling complex, multi-field application/registration web forms with locally stored personal and background details.

Partly fits

Superfill.aipartial · 62

It focuses on remembering question-and-answer pairs and using AI to match them to form fields, which can reduce repetitive form filling, but it’s less explicitly positioned around broad personal/education/work/household profiles than Auto Filler.

Won’t cover: It’s more about reusing past Q&A answers than about a comprehensive, multi-category personal profile for long forms.

Smart Form Fillerpartial · 56

It extracts structured data from a webpage and uses AI to auto-fill web forms with awareness of field types, but the catalog description emphasizes extraction and AI configuration more than a rich, multi-category stored profile.

Won’t cover: It’s geared toward extracting structured page content and filling from that, not clearly toward multi-category personal data like personal, education, work, and household.

Aiformfillspartial · 52

It’s a no-code extension that autofills forms from copied content and can handle mismatched field names, which can help for long forms, but it’s not primarily described as a stored multi-category identity profile tool.

Won’t cover: It relies on copied content to autofill rather than on maintaining a reusable multi-category profile for lengthy forms.
