Sorce for the feed. CoBlack for the pipeline

One built a swipe feed. The other built a sourcing engine.

Sorce (sorce.jobs) turns the job application into a swipe. Backed by Y Combinator and built in 2024 by three college students, it shows jobs as a card feed on your phone: swipe right, and an AI agent submits the application for you, with no form to fill. The app holds a 4.7 out of 5 rating across roughly 32,000 App Store ratings, indexes more than four million jobs, and reports over a million applications submitted for its users (App Store, 2026). It is one of the most polished consumer job apps on the market, and the idea clearly works for people.

What Sorce does

The mechanic is genuinely low friction. Upload a resume, set your preferences, and swipe. The free tier is aggressive: 40 applications a day with full AI submission at no cost. Paid plans raise the daily cap at $14.99 a week or $39.99 a month, with extra application credits sold from $2.99 to $9.99 (App Store, 2026). Sorce submits to major applicant tracking systems, among them Greenhouse, Workday, Lever, Ashby, and iCIMS, plus LinkedIn Easy Apply and company forms. This is real autonomous applying, not a browser plugin that stops at a review screen. Credit where it is due: Sorce and CoBlack both submit without asking you to click send.

What the reviews say

The App Store score is strong and the concept resonates, but the recurring complaints are specific. Reviewers report applications that fail with unclear errors, AI-written answers that come back inaccurate or off topic, and filters that surface roles far from what they asked for. A common theme is uncertainty: applications left pending for months, no way to retry, and no confirmation that a submission actually landed (App Store, 2026). Sorce has no Trustpilot presence, so the App Store is the main public record. An independent review by AutoApplier adds a structural note: Sorce shows roles inside its own feed and misses many jobs posted directly on company career pages, and applications enter a queue reviewed in order of submission, so a late swipe can lose a recruiter's attention regardless of fit (AutoApplier, 2026).

Where the jobs come from

That last point is the real divide. Sorce is a feed. You depend on what the card deck surfaces, and the deck is bounded by the platform. CoBlack is built the other way around. The Kosmos Engine sources directly from employer applicant tracking feeds and verified career pages, the channel a recruiter actually watches. Applications land in the hiring pipeline, not an aggregation layer that can carry expired or already filled listings. When the independent review notes that Sorce misses roles on company sites, it is describing the exact gap CoBlack was built to close.

The work you still do

Sorce automates the submission. It does not automate the swiping. You still open the app and make the call on every job, 40 a day on the free plan, and applications go out only while you are in the feed. CoBlack runs Auto Search, Auto Match, and Auto Apply on the server. Matching is drawn from your Career Capability Map, so the shortlist is built from what you can demonstrate rather than a filter you tune by hand, and each resume is written for the specific opening. There is no daily swipe cap and no credit meter. Because the engine watches for new roles and applies within hours, your application arrives early, near the front of that submission queue instead of the back.

Who each tool serves

Sorce is built for early-career job seekers who live on their phone and want applying to feel like a habit. It delivers on that, and the free tier is genuine value. CoBlack is built for the same person once they care more about where the application lands than how it feels to send one: direct sourcing from career pages, capability-first matching, a resume tailored per opening, no daily cap, and no fee.

Both apps apply for you. The difference is where they apply, and whether the role was ever really there.
