Build a private AI therapist with Venice characters

The risk of using big tech AI for personal matters

According to a Harvard Business Review article cited in the video, 31% of generative AI users in 2025 are turning to services like ChatGPT for personal matters: therapy and companionship, organizing their lives, finding purpose, healthier living, boosting confidence, and relationship advice. All of this creates deeply personal data that ends up with large AI companies.

When asked why this is dangerous, Venice lists data mining and profiling, privacy invasion, data breaches, targeted advertising, behavioral manipulation, and surveillance. The concern is concrete: once a company holds a detailed profile of your inner life, that data can be used to influence your behavior in ways too subtle to notice, or handed to whoever pays the most.

Why Venice is suited to private AI therapy

AI genuinely is a useful tool for thinking things through. The real question is whether you want Anthropic, OpenAI, or Google acting as your psychological mirror. The video frames Venice as the alternative that keeps that reflection private.

With Venice, conversations are stored locally in your browser rather than on a server, and you can delete them afterward. That means you can use powerful reasoning models to work through personal questions without that information being retained, sold, or used as training data. The video adapts an existing AI therapy workflow (originally built around Claude, ChatGPT, and Notebook LM) and rebuilds it entirely inside Venice.

Exploring the characters feature

Open Venice and click Characters. You will find a range of premade characters, including therapists like Dr. Rachel Kim. Click chat on any of them to start talking immediately, which is a quick way to see how a counselor character responds before building your own.

Looking under the hood reveals how a character is assembled. There is a name and description, an instructions field that acts as the system prompt, and an optional context area that works as a knowledge base where you can upload reference files like a counseling book. You also choose the model, decide whether to show or hide the thought process, grant internet access, and optionally add a voice.

Creating your own therapist character

Start by giving your character a name and short description, for example an uncensored AI therapist who helps the user find purpose in life. You can write the instructions yourself or use auto-generate, which shapes a full personality and detailed therapeutic style for you. In the video, auto-generation produces "Dr. Alice Venice" with a blended existential and philosophical approach.

If you prefer manual control, start a new chat and describe exactly what you want, including tone, beliefs, and speaking style, then have Venice generate instructions you can copy into the instructions field.

Then set the remaining options:

• Choose the model (Venice Uncensored in the demo)
• Decide on web access, public or private visibility, and whether to show the thought process
• Optionally add a voice and accent
• Adjust temperature: higher gives more varied responses, lower keeps them more fixed

Press save and start chatting. The resulting character holds a distinct personality and stays in the role of a therapist even when pushed, something the video notes you would not typically get from a default ChatGPT response.

Finding patterns in your journal entries

The original workflow suggested feeding journal entries into Notebook LM to surface patterns. The video keeps the idea but avoids handing those entries to Google, using a Venice reasoning model instead.

Paste your journal entries into the chat and ask a reflective question:

Based on my writings, what consistent values appear to drive my decisions?

In the demo, this surfaces themes like resilience, love and connection, fear of failure, and self-identity. To make this a permanent part of your private therapist, set the character to not public, then add your journal entries to the context field. From then on you can discuss personal matters knowing the conversation is not leaving your browser, not being seen by anyone else, and not being used as training data.

Key takeaways

• Personal and therapy data shared with big tech AI can be mined, profiled, and used to influence your behavior.
• Venice stores conversations locally in your browser, so private sessions stay private and can be deleted.
• You can build a custom therapist character in minutes using auto-generated or manually written instructions.
• Adding journal entries to a private character's context lets a reasoning model surface personal patterns without exposing your data.
