Zinley, which topped Product Hunt's best-of-August-2026 leaderboard, prices access on a credit system from free up to a $200-ish Max plan, while Hey Noah still will not publish pricing. Co-Active Coaching's designed-alliance principle says trust requires explicit, negotiated terms before you hand over calls and email, and only one of these two trending AI representatives currently clears that bar.
My assistant used to be a shared inbox and a lot of hope. Then this month two products landed in my feed within days of each other, both pitching the same unsettling idea: give an AI its own phone number and let it be you on the call.
Zinley is the more concrete of the two. It's currently sitting at #1 on Product Hunt's ranked list of the best products of August 2026, and its pitch is specific: your agent gets its own phone number and email inbox, remembers the people in your life so you stop re-explaining backstory, and reports back in plain language once a task is done. Pricing is a credit system, not a flat fee: free to start with 2,000 monthly credits and one call at a time, the $20/month Plus plan raises that to 4,000 credits and five simultaneous calls, the $100/month Pro plan jumps to 20,000 credits and 100 daily, and the Max plan doubles that again to 40,000 credits with unlimited call length and 20 calls at once. Every action — drafting an email, placing a call — burns credits, so your actual monthly cost depends on usage, not the landing-page number.
Hey Noah takes the opposite stance on almost everything. It pitches itself, in its own Product Hunt launch copy, as "like Tesla Full Self Driving, and not cruise control" — an autonomous EA that manages your calendar, relationships, and follow-ups across email, text, and WhatsApp without you steering each step. Two reviews this year from the AI-assistant comparison site Catch (a competitor, worth noting) both land on the same conclusion: it's a genuinely early-stage product for small teams, and its pricing isn't published anywhere. Its own terms of service reserve the right to "accept, reject, suspend, or revoke access to any user at any time, with or without cause, at our sole discretion" — standard boilerplate for an early product, but not the language of a company ready to tell you what the deal actually is.
The question I actually care about as a coach isn't which one has more integrations. It's Co-Active Coaching's first real test for any relationship where you're handing someone — or something — authority to act on your behalf: the designed alliance. Henry and Karen Kimsey-House and Phillip Sandahl built the coaching model on the idea that a working relationship has to be consciously, explicitly negotiated before either side acts, not assumed. "Power is granted to the relationship, not to the coach," they write — and the same test applies to an AI about to call your vendors and email your clients as you. If you can't name the terms — what it decides alone, what it must ask first, what it costs to run — you haven't designed anything. You've just granted access.
The second cornerstone that matters is what Co-Active calls self-management — "the light should be shining on the coachee, not the coach." A good AI representative should make itself invisible in the outcome: the vendor gets booked, the candidate gets screened, and nobody downstream thinks about the tool. Zinley's product screenshots lean into this — a receipt that reads "two screens complete, one strong yes, one pass, with reasons," not a transcript you have to parse. Hey Noah's positioning does the opposite: it wants you to know it's driving, autonomously, the way Tesla wants you to trust Full Self Driving. That's a legitimate product bet, but it inverts the cornerstone — the light is on the assistant's autonomy, not the quiet completion of your work.
Scoring both against what a designed alliance actually requires, with Catch — an established $99-flat-fee competitor, cited here only as a reference point for a mature, disclosed alliance:
| Criterion (Co-Active Coaching) | Zinley | Hey Noah | Catch (reference) |
|---|---|---|---|
| Explicit, negotiated terms up front | 4/5 — credit tiers published | 2/5 — no public pricing | 5/5 — flat $99, disclosed |
| Self-management (invisible in the outcome) | 4/5 — plain-language receipts | 2/5 — markets its own autonomy | 4/5 — stays in its lane by design |
| Whole-person memory (your people, not just tasks) | 5/5 — explicit relationship memory | 3/5 — claimed, less evidenced | 3/5 — workflow-first, less relational |
| Trust floor (security, revocation terms) | 3/5 — credit costs can creep | 2/5 — revokes access "at sole discretion" | 5/5 — SOC 2 Type II, CASA Tier 2 |
None of this is a verdict that Zinley is simply "good" — a few weeks of public availability isn't enough runway to know how it handles an actually awkward call, and a credit system that looks cheap in the free tier is exactly the kind of thing that creeps once you're dependent on it. What I can say is narrower: of the two most-talked-about "AI represents you" launches this month, only one currently gives you enough information to design the alliance before you hand over your phone number. I wouldn't put either one in front of a client-facing call yet without a human listening to the first ten calls live — the exact review gate I already run with junior human hires in their first month, and an AI doesn't earn a shorter runway than a person would.
Coaching for Performance and Co-Active Coaching both make the same claim in different language: unlocking real performance from any relationship — human or software — starts with explicit terms, not blind trust. Until Hey Noah publishes what it costs and what it will do without asking, it isn't failing because it's a worse product. It's failing because there's no alliance to evaluate yet.
