How it works
The problem nobody solves
Copying and pasting data field by field, form after form. Generic autofill tools (1Password, LastPass, browser autofill) work with simple forms, but fail on complex portals:
- Non-standard fields: Identifiers like
field_0x3Aorfrm_datos[nif]that no generic autofill recognizes. - Specific codes: Street type codes (CL, AV, PS, PZ), cadastral references, custom numbering systems.
- Chained dropdowns: You select a field and the next one reloads dynamically. Generic autofills don’t wait — Papeleo does.
- Local validation: ID formats, checksums, country- or portal-specific rules.
- Repeated forms across multiple platforms: The same product on Wallapop, Milanuncios, Vinted and Coches.net — each portal with its own form and categories.
- Each portal’s own system: Product categories, shipping options, contact fields — everything different on each platform.
Result: hours wasted filling in the same data over and over.
What Papeleo does for you
Fills any online form in seconds
Works with any web form. Create your own mappings to link each CSV column to the right form field — once configured, fill with one click. Mappings can be exported and imported to share or reuse.
Select and fill
Pick the record, click Fill. Papeleo writes each value into the right field — even on portals with non-standard fields.

Organize your data in collections
Import a CSV of clients, another of products, another of vehicles — each one is a separate collection. Switch records with one click. 2 collections and 10 records free, unlimited with Pro.
Import, organize, configure
Import CSV or XLSX, manage collections, configure mappings and auto-lock — all from the settings page.

One collection per data type
Clients, products, vehicles, children — each collection has its own structure. A seller can have their identity + 50 products. An accountant can have 30 clients + their company data.
Validates before you submit
NIF, CIF, IBAN — automatically verified before you hit Submit. Zero transcription errors.
Your data never leaves the browser
AES-256 encryption. No external servers. No cloud accounts. Everything stays on your machine.
Automatic field mapping
Import your CSV and Papeleo auto-maps columns to form fields. Review, tweak if needed, and you're set.

Three steps to filling
Create a password, import your data, and start filling. No accounts, no servers — everything local.
