Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Copilotly
- Copilotly explicitly disclaims that its legal, medical, and financial copilots are not a substitute for licensed professional advice, which limits its use for anything requiring accountable expert sign-off.
- The free plan caps usage at 3 copilots and 50 messages per day, pushing most real usage onto the paid Pro tier.
- It relies on third-party foundation models (GPT-4o, Claude, Gemini, DeepSeek) rather than proprietary domain models, so answer quality is bounded by those underlying models.
- There is no published documentation site or API, limiting integration options for developers or teams wanting to build on top of it.
- Safari support is listed as 'coming soon' rather than available, so macOS/iOS Safari users are currently unsupported in-browser.
PromptLayer
- The free plan is capped at only 2,500 requests per month, quite limited for active production use.
- The Team plan jumps to $500/month, a large step up from the $49/month Pro plan.
- Overage transaction fees apply on top of subscription costs, which can make total spend less predictable.
- Enterprise-grade features like HIPAA BAAs and custom deployment require contacting sales.

Answered from the vendors’ own pages
Copilotly: What do you get on the free plan?
Three copilots of your choosing, 50 messages a day, conversation history and the browser extension. No card and no time limit: the 50 messages are a daily cap that resets rather than a total.
SourcePromptLayer: What does PromptLayer cost?
PromptLayer has a free plan, a Pro plan at $49/month, a Team plan at $500/month, and custom Enterprise pricing, with additional usage billed per transaction beyond plan limits.
SourceCopilotly: How much is Pro, and is annual cheaper?
Pro bills three ways: $4.99 a week, $29 a month, or $290 a year. The annual cycle works out at about $24.17 a month, so it is the cheapest of the three.
SourcePromptLayer: Is there a free plan, and what are its limits?
The Free plan includes 5 users, 2,500 requests per month, 1 workspace, 250 monthly eval cell executions, and datasets up to 10MB.
SourceCopilotly: Can I try it before paying, and can I get a refund?
Pro has a three-day free trial and a seven-day money-back guarantee. Subscriptions can be cancelled at any time with no cancellation fee.
SourcePromptLayer: How is usage metered beyond the plan limits?
Additional usage is charged per transaction for requests, agent runs, and evaluation cell runs, at $0.003/transaction on Pro and $0.002/transaction on Team.
SourceCopilotly: Which models does Copilotly run on?
It routes to third-party foundation models rather than its own: GPT-4o, Claude, Gemini and DeepSeek. Answer quality is therefore bounded by whichever of those handles a query.
