If you searched for the best AI therapist, you probably want help that is there when you need it, costs less than weekly sessions, and does not judge you. Those are real needs. The honest answer is that no app can be your therapist. Therapy is a licensed clinical service, and Illinois now restricts AI from providing it. What AI can do is help you think out loud, name what you are going through, notice patterns, practice a coping exercise, and have somewhere to turn at 3am.
We make Vent Now, so read this knowing where we stand. Vent Now is an AI emotional support companion, not a therapist. Every detail about Wysa, Ash, and ChatGPT comes from their own FAQs, app store listings, and help centers, and we say plainly when another tool, or a human, is the better fit.

Vent Now
Everyday reflection and emotional support that remembers your story
Emotional companionText and voiceText Aspen in iMessage
Vent Now is an AI emotional support companion, not therapy. You talk with Aspen by text or voice, or text Aspen directly in iMessage, and Aspen remembers prior conversations so it can connect moods, triggers, and recurring patterns over time. It was built with a licensed therapist on the team, and its content and guidance are reviewed by a licensed therapist, but Aspen does not diagnose or treat anything. In our 2026 survey of 197 users with accounts at least 28 days old, 95% agreed Vent Now helps them notice patterns in their emotions (self-reported by retained users).

Wysa
Structured self-help exercises, with human coaching in some locations
Guided self-helpAI chat and guided prompts
Wysa pairs an AI conversation with self-help tools designed by its clinical team, and talking to Wysa AI is free. A premium version adds more tools, and in some locations Wysa offers human coaching at an additional cost. Wysa’s own FAQ says it is not a substitute for professional medical advice, is not recommended for crisis situations, and is not suitable for people with severe and enduring mental health problems.

Ash
Goal-focused conversations and weekly insights, for adults
AI for mental health supportVoice and text, any time
Ash, made by Slingshot AI, describes itself as AI designed for mental health. You can talk or text with it any time, it remembers what you share, and it builds a personalized program with weekly insights about your patterns. Its App Store listing is candid about its limits: Ash is for adults 18 and over, it sometimes makes things up, it is not a replacement for medical diagnosis or treatment, and it is not designed for use in a crisis.

ChatGPT
Practical questions, like what therapy involves and how to start looking
General AI assistantText, voice, images, and files
ChatGPT is a general AI assistant, not a mental health product. It is useful for the practical side: explaining what different kinds of therapy involve, drafting a message to a therapist’s office, or listing questions for a first appointment. OpenAI says ChatGPT may show a check-in message and localized crisis helplines, such as 988 in the US, when it detects signs of distress. It can make mistakes and is not a licensed professional.
