Aion is a form-filling tool that automates the preparation of UK visa, settlement, and citizenship applications on gov.uk from a client’s supporting documents.

Key features and functions include:

Document upload and data extraction
Users upload a client’s documents as individual files, a folder, or a .zip archive. Aion extracts identifying details, including names, dates, passport and reference numbers, addresses, and relationship, employment, and travel history, into a single summary.

Caseworker review before filling
The extracted summary is presented for the firm’s caseworker to check and edit before any data is entered into an application, so the information used to fill the form has been reviewed by a person first.

Automated gov.uk form-filling
Once reviewed, Aion fills the corresponding live application on gov.uk in a browser view the firm can observe as it runs.

Stop at Declaration, no auto-submission
The tool halts at the application’s Declaration page in every case and does not submit any application itself; a member of the firm reviews the completed form and submits it.

Missing-information reporting
After filling, Aion returns a report identifying any fields left missing or uncertain, for the review team to resolve before submission.

Route coverage
Aion is described as covering UK immigration application forms published on gov.uk other than asylum, including spouse and partner applications under Appendix FM, settlement and indefinite leave to remain, naturalisation and citizenship, Skilled Worker, family, student, and standard visitor applications.
