How it works
Add your documents
Upload CVs, certificates, transcripts and notes. Group them in folders and add instructions to each folder. Text is extracted from PDF and Word files.
Search for jobs
Search Remotive, Himalayas, Jobicy, Remote OK and Arbeitnow, or the web. Each posting gets a fit score and a one-line reason.
Apply
Cosium picks a CV, drafts a cover letter and answers to screening questions, and fills the form. Each application is tracked on a board.
Features
Browser extension
Adds an Cosium button to pages in Chrome and Edge. It fills text fields, dropdowns, radio buttons and checkboxes, attaches your CV, and answers free-text questions from your documents.
Android app
A floating button over other apps that fills forms using Android accessibility.
Job search
Five public job boards, plus web search through your AI provider for local roles.
Cover letters
Drafted from your CV and the job description. You can edit them before sending.
Chat
Ask about your documents, or ask Cosium to search, save notes or prepare applications.
Your own AI key
Cosium calls OpenAI or Anthropic directly with your key. Usage is billed by the provider.
Private accounts
Each account sees only its own documents, jobs and applications. Password fields are never filled, and automatic submission is off by default.
