Analytics
See what's actually working.

each application keeps the resume you sent
Documents
Documents that remember where they went.
Import a resume from PDF or Word, choose from five templates and run an offline readability check. Write cover letters paragraph by paragraph, in your own words, with nothing generated for you. Each application keeps a note of the version you sent.

the rounds that follow
Interview Suite
Ready for every round.
Log each round, the recruiter you spoke to and your research notes, keep a question bank, and build STAR answers. A prep checklist covers the round ahead, and every interview, follow-up and deadline goes on one calendar you can export to Google or Outlook.

the people you meet along the way
Network
Know who you know.
Keep recruiters, referrals and everyone else you meet in one list. Seisin points them out when it matters: when you add an application at their company, or start a cover letter to it.

Patterns in your search
See which applications get replies.
The funnel
In this example, referrals get a reply three times out of four, and every job board sits around half. That gap is a good hint about where to spend next week.
Your weekly pace, pipeline health and conversion funnel come straight from the applications you've logged, so there's nothing to set up. How the analytics work

Nothing from your search.
There's no account and no cloud copy, and your applications, documents and notes never leave your computer. The app only goes online for three things: an update check, which you can switch off in Settings, reading a job post when you paste its link, and exchange rates when you ask for them.

What people ask first.
A spreadsheet works for a list of applications. Once you're also tracking interview rounds, prep notes, resume versions and competing offers, keeping it all in one sheet becomes a project of its own. Seisin keeps the application, the interview prep, the resume you sent and the offer you got on one record, and works out the analysis for you, with no formulas.
They're web apps: you sign up for an account, your data lives on their servers, and many of the useful features sit behind a monthly plan.
Seisin runs on your own computer with no login, and the analytics are part of the free app.
Not yet. Everything on this page is free to use today, including the tracker, your full history and the analytics.
A premium version is planned for later this year. It's meant to add more on top of the free app, at a price that works for someone in the middle of a job search.
The free plan does have a few limits. Exporting a resume is 10/month, exporting a cover letter is 3/week, and adding new contacts to Network is 20 in your first 30 days, then 5/month, all of which reset on a schedule. Each contact can also be linked to one application at a time. There are no limits on saving, editing or viewing, and reaching a limit doesn't remove anything you've already made. Settings shows what's left and when each limit resets.
In a local database on your own machine, created during setup. Nothing from your job search is uploaded, and there's no account to create or lose access to.
Yes. Settings lets you export everything to CSV or Excel, or save a full backup, at any time.
Windows, macOS on Apple Silicon, and Linux as either a .deb package or an AppImage.
The installers aren't code-signed yet, so Windows SmartScreen and macOS Gatekeeper flag them by default. Each download page has the exact steps to get past it. It's a one-time thing per install.
