Tsenta waits for approval. CoBlack works hands-off

Broad coverage, but you approve every send

Tsenta (tsenta.com) is a new Y Combinator startup from 2026 that applies to jobs across an unusually broad footprint: it monitors more than 50,000 company career pages and supports 19-plus applicant tracking systems, Workday, Greenhouse, Lever, and Ashby among them (Tsenta, 2026). Its coverage is genuinely wide, and it is transparent by design. But its core design choice is the opposite of hands-off: Tsenta shows you a diff of every change and waits for your approval before it sends.

What Tsenta does

For each role, Tsenta tailors a resume and drafts screening answers in your voice, then presents the changes and asks you to approve or edit before submitting, with a receipt after (Tsenta, 2026). It runs its automation on-device, and reaches you across a web dashboard, a Chrome extension, iMessage, WhatsApp, and even an MCP server and CLI for AI agents, a real and distinctive surface. Pricing is a 25-application free trial, then metered by volume: Starter 19 dollars a month for 600, Pro 39 dollars for 1,500, Power 99 dollars for 4,500 (Tsenta, 2026). There is no ongoing free tier.

An honest read on trust

Tsenta is weeks old, so there is little to review. It has no Trustpilot listing, no G2 profile, and no app store presence, and the only ratings are single-sample aggregator entries (LoopCV, 2026). Its legitimacy is visible, YC-backed, an AI disclosure page, submission receipts, but it has no independent track record yet. We will judge it on its design, and give credit where its design is strong.

Where CoBlack differs

The clean difference is the approval step. Tsenta relocates the work rather than removing it: instead of typing forms, you review and approve every application. CoBlack submits server-side with no review step, so the applying leaves your plate entirely. It is also free with no meter, where Tsenta charges after 25 applications and prices by volume. And CoBlack tailors from a persistent Career Capability Map you have verified, sourcing from validated, ghost-filtered career pages, where the edge is source quality and depth rather than raw breadth.

What Tsenta does well

Fairness matters here. Tsenta's stated ATS breadth is among the widest of any tool in this space, and its agent access through an MCP server and CLI is something CoBlack does not offer. If your priority is maximum platform coverage with a human check on every send, Tsenta is a serious, thoughtfully built option. CoBlack does not contest those points. It makes a different trade.

Who each tool serves

Tsenta suits someone who wants very broad coverage and prefers to approve each application, and does not mind paying per volume on a brand-new tool. CoBlack is for the person who wants the applying to happen without them, from validated sources, tailored per opening, for free. Both apply across the ATS. The difference is whether you have to sign off each time. Targeted applications convert to interviews at roughly 7 to 9 percent versus 2 to 3 percent generic (Scale.jobs, 2026).

Tsenta shows you every application and waits. CoBlack sends them, so the only thing left on your plate is the interview.
