Stay on your mainline.
Your commit history captured the least important half of what you did. Mainline captures the rest — the unblocks, the design calls, the mentoring that actually gets you promoted — so review season finds you holding receipts, not reconstructing six months from memory.
One email when it opens. No spam, and I won't share your address.
You can't remember what you did last Tuesday.
And the work that matters most is the work that vanishes first. The afternoon you spent unblocking two teammates, the design you argued through, the incident you steered — none of it leaves a trace you can find later. Commits get a permanent record. Your highest-leverage work gets nothing.
Then review season arrives, your manager asks for impact, and you're reconstructing six months from a commit history that captured the least important half of what you did.
Capture both halves of the work. Tie them to where you're headed.
Setup takes a few minutes once. After that it's two minutes a day.
GitHub, Jira, and Linear. Read-only OAuth, about a minute. Mainline never writes to your repos or moves your tickets.
Merged PRs and closed tickets pull in on their own. The work GitHub can't see — an unblock, a design call, a mentoring session — is one tap from your phone or editor. Both kinds land in the same place, neither costs you a context switch.
Mainline maps each day to your OKRs and your next level, then says so when nothing's mapped in a week — "three weeks in, nothing you've shipped points at your top goal." It redirects you mid-quarter, while you can still change the outcome.
The honest objection: you won't remember to log it. That's the point. Your PRs and closed tickets pull in on their own — the rest is one tap from the editor you're already in. No new tab, no end-of-week backfill from memory, no doc you abandon by week three.
A generic planner doesn't know what you do all day.
Not Sunsama. Not Todoist. Those organize your hours. And no, it's not a commit-counter either — lines of code were never the measure of impact, and a tool that scores you on them is selling you a vanity metric. Mainline connects the work that actually moves your career to where you're trying to take it.
It captures the work GitHub can't see
The unblock, the design doc, the architecture call, the hour you spent mentoring — your highest-leverage work produces few commits or none. One tap puts it on the record. Commits are one input here, never the headline.
It writes your impact narrative, not a commit log
Come review, promo, or your next 1:1, Mainline assembles what you did as scope, influence, and outcome — the story a packet actually needs — drawn from six months it remembered so you didn't have to.
It tells you when you've drifted
A diary tells you where you've been. Mainline tells you you're off course — "three weeks in, nothing you've shipped maps to your top goal" — while there's still a quarter left to fix it. Forward-looking, not a logbook.
It lives where you work and knows your week
It reads from GitHub, Jira, and Linear — no new tab to forget. And it knows an incident week from a feature week, so a day in the war room counts as the work it was, not a gap in your output.
Stop losing the work that gets you promoted.
I'll send one email when it opens — nothing else. While you're here, one question helps me build the right thing.
// thanks — that helps me prioritize.
No spam. No sharing your address. Just one note when the door opens.
I'm building this because I walked into my own review with half my best work missing — the unblocks and design calls I couldn't reconstruct six months later. Mainline is the tool I wanted that week.
