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.

Haystack

Requires Python programming knowledge for advanced customization
Steeper learning curve compared to no-code platforms
Community support only on free tier may limit enterprise adoption
Ongoing maintenance dependency for open-source framework
