About this extension
Save any job posting into Seisin in one click.
Seisin is a free job search manager that runs on your own computer: applications, resumes, cover letters, interviews, contacts and offers in one place, with analytics that build themselves. This extension is how jobs get in without copying and pasting.
How it works
Open a job posting and a small Seisin mark appears in the corner. Click it (or the toolbar icon, or press Alt+Shift+S), check the role and company it found, and click Planned or Applied. That's it: the job is in Seisin with its location, salary, work type and the full job description, which stays after the advert comes down. Add the resume you sent or a note under Add details if you want to.
Seisin closed? Choose "Add it when Seisin opens": the job waits in your browser and goes into your Planned list within seconds of Seisin opening.
Works on any job board or careers page that publishes its job details, including LinkedIn, Indeed, Glassdoor, Hiring Cafe, Handshake, Greenhouse, Lever, Workday and more. Anything it can't find, you type in. Saving is unlimited and free.
Private by design
To show its mark on job postings, the extension checks each page you open for the job details the page publishes, inside your browser. That check sends nothing and keeps no record. Only when you save does it send the posting to the Seisin app on your own computer, and nowhere else: no account, no cloud, no analytics, no tracking. Hide the mark on any site with one click. Your job search never leaves your machine.
Before you start
You need the free Seisin desktop app for Windows, macOS or Linux, from getseisin.com. Click Connect in the extension and Allow in Seisin, once.
