AI is increasingly being used to explore thoughts and feelings, find information about mental health, understand symptoms and look for support.

Some people are also turning to AI chatbots as an alternative to speaking to a therapist.

Our 2026 Public Perceptions Survey1 found that 16% of people who had used AI for their mental health had used it instead of a therapist.

But what is different about therapy with a human? Therapy is about more than conversation. It involves a relationship with another person who can listen, notice, understand and respond.

We asked BACP therapists about what happens in therapy that can be difficult for AI to replicate, from the therapeutic relationship and non-verbal communication to professional judgment and safeguarding.

Why the therapeutic relationship matters in therapy

The relationship between therapist and client is central to therapy. It develops within professional boundaries, but it’s also a human relationship.

Counsellor Amanda Macdonald explains:

“The therapeutic relationship is generally considered the most important aspect of what makes therapy successful.”

She adds:

“Within those boundaries, the therapist brings the real sense of who they are, and this is where AI cannot respond in the same way.”

A therapist is also able to notice things that a client may not put into words.

“AI can only experience a reply from the client that the client explicitly provides, so any small indications of incongruence or disagreement will not be communicated. A small frown, or a reluctant agreement will be missed.”

Why human therapists notice more than words

For psychotherapist and supervisor Jeanine Connor, the information available to a human therapist goes far beyond what someone says.

“As a psychodynamic psychotherapist I observe and respond to all forms of communication, including tone of voice, facial gestures, body posture and movement, how a client physically presents and how they move in the space.”

She also pays attention to what might not be said directly:

“I will notice what they say and wonder about what is unsaid, which could signal either conscious or unconscious avoidance.”

Jeanine says that the way a client relates to their therapist can also provide important information about their relationships and experiences.

“I will notice how a client relates to me, how easily they trust me, what their defences are, how they respond to boundaries, which are clues to the quality of their external relationships.”

She adds:

“AI cannot read between the lines; it can only respond to direct written cues which are only a tiny part of communication.”

Therapist Francesca Francis also highlights the importance of body language in therapy:

“It’s important to highlight the importance of body language in sessions. I think this is a key element in therapy and can help a therapist identify unconscious triggers, which can indicate what needs to be explored further in sessions. This is something that is irreplaceable from an AI standpoint.”

Why therapy is more than advice and answers

Therapy isn't necessarily about providing an immediate answer or telling someone what they should do. The therapeutic relationship can also involve moments of challenge, disagreement or misunderstanding.

As Jeanine explains:

“Human therapists aren’t like that – sometimes there are missteps, sometimes there is rupture and repair, sometimes clients need to be challenged in the purpose of helping them to make positive changes.”

These moments can become part of the therapeutic process, giving the therapist and client an opportunity to explore what has happened and what it might mean.

Amanda describes this as an important part of how therapy works:

“In therapy, the change comes from within the client, not from an external expert directing the client to what they should do.”

Why context matters in therapy

Understanding someone's thoughts, feelings and behaviour can involve looking beyond what is happening for them right now.

Jeanine says:

“I believe that current challenges make sense only in the context of personal developmental and family history and within a consideration of biological, social and cultural factors.”

For this kind of therapeutic work, understanding someone's wider context can take time.

“This takes months, sometimes years, to explore but leads to lasting change.”

The importance of professional judgment and safeguarding

Therapists bring training and professional responsibilities to their work. This includes being alert to risk and safeguarding concerns and considering the individual circumstances of the person they are working with. As Amanda explains:

“Well-trained therapists are always alert to risk and safeguarding. We use our knowledge of the individual client’s circumstances to respond ethically and in that client’s best interest.”

Therapists can also draw on professional support when making decisions about a client's care.

“We can also consult with our clinical supervisor and/or professional organisation to support decision making. AI doesn’t know what it doesn’t know.”

Amanda also highlights the difference in the safeguarding framework around human therapy:

“AI chatbots are not offering the same framework of safeguarding as a qualified therapist.”

Can AI be used for mental health support?

AI can provide information and respond to people who are looking for support, but therapists say there are important differences between this and a human therapeutic relationship.

As Amanda explains:

“AI can chat, respond to direct questions and imitate connection. It cannot feel, empathise, use intuition or draw on (and share) human experience.”

She also stresses that people should be able to make their own choices about the support they use, while recognising the concerns around AI.

“It’s important that people have choice, and a therapist should never tell someone they mustn’t use AI therapy. However, there are some serious concerns over safeguarding, as well as the widening awareness of the risks that AI can bring to everyone.”
