The short version

  • Only Copilotly has a free tier, so it costs nothing to try first.
  • Each has a real cost: C3 AI Suite the commercial model bundles software with heavy professional services, so the licence line in the quote understates the first-year cost by a wide margin and budgets set from the licence alone overrun.; 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.
  • They diverge on capability: C3 AI Suite covers Type system, Copilotly covers 131 specialist copilots.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

C3 AI Suite

  • The commercial model bundles software with heavy professional services, so the licence line in the quote understates the first-year cost by a wide margin and budgets set from the licence alone overrun.
  • Applications are written against C3 proprietary types, so nothing built on the platform ports to a generic Spark or Databricks stack without a rewrite, which makes exit expensive after two or three years.
  • Contracts have historically been large multi-year commitments with a small number of very large customers, which means pricing is negotiated case by case and small buyers get little leverage.
  • Skills are scarce outside C3 itself, so hiring an engineer who already knows the platform is hard and the customer stays dependent on the vendor for extensions.
  • Pre-built applications need substantial configuration against the customer data model before they produce anything, so the marketing claim of a packaged app understates the integration work by months.

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.

Answered from the vendors’ own pages

C3 AI Suite: Does C3 publish pricing?

No. Everything is quoted, and the shape of the deal, pilot then subscription, means the first number you see is for a proof of value rather than the platform.

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.

Source
C3 AI Suite: Can it run in a classified environment?

Yes. C3 supports air-gapped and government cloud deployments, including FedRAMP-authorised environments, which is a large part of why defence buyers choose it.

Copilotly: 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.

Source
C3 AI Suite: Do we own the models we build?

You own the models and the data. The application logic is written in C3 types, so the artefacts are portable in principle and impractical to move in practice.

Copilotly: 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.

Source
Copilotly: 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.
