Synarch vs Slashy
Slashy is the deepest email-native competitor: real per-recipient memory, voice-matched drafts, follow-up and open tracking, meeting prep — inside its own email client at $25/user/mo. But its world ends at the inbox: it clears the email a misaligned meeting generates without ever asking whether that meeting deserved to exist, and adopting it means switching email clients. This table shows the boundary: Slashy does your email. Synarch decides what deserves your time — email included.
Slashy: $25/user/mo · Synarch: $79/mo solo
| Dimension | Slashy | Synarch |
|---|---|---|
| Core job | Clears the inbox: drafts in your voice, triages, tracks follow-ups and opens, preps meetings — all within email, inside its own client. | Classifies all work against your goals, then acts: declines misaligned meetings, sends drafts at earned trust, books deep work — across your existing calendar and inbox. |
| Work-type classification (D/M/E/R) | Not offered (as of July 2026). Classifies by urgency/noise and sender memory, not work type. | Automatic D/M/E/R classification of every activity against your stated goals. |
| Time budget enforcement | Not offered (as of July 2026). Schedules meetings; no evidence it declines them or accounts for where your hours go. | Enforces your Direction / Multiplication / Execution ratio. Auto-declines misaligned meetings; auto-books deep work per OKR. |
| Email triage & voice-matched drafts | Strong: voice learned from full sent history, per-recipient memory that compounds, open tracking, in-thread availability sharing. Requires switching to Slashy as your email client (Gmail only; Outlook coming). | Triage by strategic alignment + sender intelligence; drafts placed in your existing Gmail — no client switch; autonomous send at earned trust. |
| Autonomy model | You approve every draft before send (per their FAQ). "Read Mode" restricts to read/draft only. No graduated path to autonomous action found. | Shadow → Draft → Autonomous ramp over weeks. At earned trust: auto-RSVP ≥80% aligned, auto-decline ≤30%, autonomous send. |
| Trust / safety architecture | Binary toggle (full review vs. Read Mode) plus memory instructions like "never send directly." | Shadow mode default (zero power). 28-day recovery lockdown after surprise. Complacency circuit-breaker. Per-category opt-in with 30-min undo. |
| Weekly accountability receipts | Follow-up and open tracking; no time accounting. | Certainty Score (peer percentile), D/M/E/R ratio audit, hours-reclaimed ledger, every action logged, 12-week archive. |
| Pricing | $25/user/month (no annual plan), 7-day free trial (credit card required). Enterprise adds SSO/SCIM. | $79/month solo (500 actions included), $790/year, 14-day trial — no credit card. Overage $0.10/action. |
Pick Slashy if
- •Your pain is genuinely inside the inbox — drafting, follow-ups, meeting prep — and you're willing to switch email clients to fix it.
- •You want email-native depth (open tracking, in-thread scheduling, per-recipient memory) at $25/user.
- •Your team needs SSO/SCIM and a shared-inbox workflow today.
Pick Synarch if
- •Your problem is upstream of the inbox: the meetings and asks that generate the email were never judged against your goals.
- •You refuse to switch email clients — Synarch is an invisible layer on the Gmail and Calendar you already use.
- •You want autonomy that is earned and audited (trust ramp, recovery protocol, Monday receipts), not a binary review-everything toggle.
FAQ
Slashy also says it "does the work, not just assists." How is Synarch different?
Scope and anchor. Slashy does the *email* work — drafting, triage, follow-ups — judged by urgency and sender memory. Synarch acts on your whole time budget — calendar, inbox, and deep work — judged against your stated goals. Slashy clears the email a misaligned meeting generates; Synarch declines the meeting.
Do I have to change how I work?
With Slashy, yes: it is a standalone email client, so you leave Gmail's interface and live in Slashy's. Synarch changes nothing — it operates through the Gmail and Google Calendar you already use, and you can keep working exactly as before while it earns autonomy in the background.
Can I use Slashy and Synarch together?
Technically yes — Slashy would handle in-inbox work while Synarch enforces the calendar and time budget. But both will draft against the same inbox, which gets confusing fast. If your pain is strategic drift rather than inbox mechanics, start with Synarch.
