# Sintra alternative

*Sintra sells a roster of AI helpers for SMB owners and solopreneurs. Fidelic sells senior agents for hiring managers — with a published constitution, a Day-Week-Month schedule, and a four-tier autonomy gate on every action.*

Looking for a Sintra alternative?

Sintra sells AI helpers (Cassie, Buddy, Penny, etc.) for SMB owners — a roster of personas you can deploy quickly, marketed at solopreneurs and small teams.

## What Sintra does well

- The named-helper format reads as approachable in a category dominated by faceless platforms — Sintra moved early on the persona-first marketing register.
- Lifetime-deal pricing and one-time-purchase structures make the SMB economics straightforward; the buyer doesn't have to forecast spend.
- Strong SMB and creator-economy distribution; the founder content has built genuine community pull.
- The helpers are bounded — each Sintra persona has a clear lane (Cassie for customer support, Penny for finance, Buddy for productivity), which makes the buy decision fast.
- Browser-extension + chat-first interface gets users into the product the same day; no procurement cycle.

## Where Sintra falls short

- The helpers are productivity assistants, not autonomous role-fillers. Sintra is closer to ChatGPT-with-personas than to a hiring layer; the buyer is still doing the prompting.
- No published per-helper constitution or written limit list. The marketing surface lists what each helper does, not what it won't do.
- SMB-owner audience means the brand voice and pricing register are different. A Series-B operations lead asking "who's accountable when this is wrong" gets a different answer here.
- No constitutional gating visible. Fidelic's playbook is to publish a four-tier rule set (autonomous / review-required / escalate / refuse) before the buyer hires; Sintra's surface doesn't.
- Tasks are conversational, not trigger-driven. A Fidelic agent listens to triggers and produces structured outcomes autonomously; a Sintra helper waits for the user to start the next chat.

## Who Sintra suits

Solopreneurs, SMB owners, and small teams who want a fast, friendly persona-driven productivity layer they can use the same afternoon. The buyer is also the operator; the relationship is conversational; the work product is what the buyer would have done in ChatGPT.

## Who Fidelic suits

Hiring managers and founders at Series-A-and-up companies who need the work done autonomously, with a written constitution, a Day-Week-Month schedule, and a published list of what the agent won't do.

## Side by side

| --- | --- | --- |
| Category | AI helpers / personas — productivity layer for SMB owners | AI employment — senior agents you hire by the role |

| Constitutional gating | Not published per helper | Four-tier rule set on every agent: autonomous / review-required / escalate / refuse |
| Buyer profile | Solopreneur / SMB owner who's also the operator | Hiring manager at a Series-A+ company filling a role |
| Pricing | Lifetime-deal pricing on individual helpers / Sintra X bundles | $500 (Professional) or $1,000 (Expert) per month, cancel-anytime |
| Best for | SMBs who want a friendly persona to assist the operator | Hiring managers who want the role done while they sleep |

## Recommended Fidelic agents

- [KORA-01](https://fidelic.ai/agents/kora) ($500/mo) — If Sintra's Cassie-style customer-support helper was the right shape but the work needs to run autonomously — routing tickets, drafting renewal-risk scorecards, escalating before guessing. KORA-01 takes that work end-to-end on a constitution your CS lead writes.
- [VYRA-01](https://fidelic.ai/agents/vyra) ($500/mo) — If Sintra's prospecting helpers were the use case but the inbound queue needs sub-hour response and a published ICP rule on every reply. VYRA-01 runs the inbound surface inside a four-tier constitution.

## Honest note

Sintra wins where the buyer is the operator and the work is conversational — a one-person business that wants a persona to chat with, the same afternoon, for the price of a tool. We will lose those deals; we are not built for that audience. We win where the buyer is hiring an agent to do work that runs while they're not at the keyboard.
