MindDiary is an all-in-one practice management and between-session engagement platform built specifically for therapists, counsellors, psychotherapists, psychologists, group practices, and therapy clinics.

MindDiary brings the client journey into one connected workspace — from initial enquiry and digital intake through appointments, sessions, between-session work, documentation, and practice administration.

Therapists can create digital intake forms, capture and manage leads, schedule appointments, conduct telehealth sessions, prepare for upcoming sessions using relevant client context, and create therapist-reviewed AI-assisted clinical note drafts.

A key difference is MindDiary's focus on what happens between therapy sessions. Clients can use journaling, mood tracking, guided reflections, homework, and check-ins between appointments. Relevant information can then contribute to session preparation, helping therapists maintain continuity instead of treating every appointment as an isolated event.

MindDiary also provides public therapist profiles and lead forms, client management, appointment reminders, invoicing, and revenue follow-up tools to help practices reduce administrative work and keep important tasks from falling through the cracks.

AI is used to assist therapists rather than replace professional judgement. Therapists remain in control of clinical documentation and how client information is used.

By combining practice management, clinical workflow support, and between-session engagement, MindDiary aims to reduce the number of disconnected tools therapists need while giving them better context for each client relationship.

s3-lambda features and specs

  • Batch processing of S3 objects
    s3-lambda provides a straightforward way to perform batch operations on large numbers of S3 objects, enabling map, filter, and reduce-style processing over entire S3 buckets or prefixes without writing boilerplate code.
  • Familiar functional API
    The library uses a functional programming paradigm with operations like map, filter, and reduce, making it intuitive for JavaScript developers to process S3 objects using patterns they already know.
  • Built-in concurrency control
    s3-lambda handles parallel processing of S3 objects with configurable concurrency, allowing users to control how many operations run simultaneously and avoid overwhelming AWS resources or hitting rate limits.
  • Context-aware operations
    The library provides a context object within each operation that includes useful metadata about the current object being processed, simplifying access to S3 object properties during transformations.
  • Easy integration with Lambda
    Designed to work seamlessly within AWS Lambda functions, making it straightforward to set up event-driven, serverless pipelines for processing large volumes of S3 data without managing infrastructure.

Possible disadvantages of s3-lambda

  • Unmaintained project
    The repository appears to be no longer actively maintained, with limited recent commits and unresolved issues, which raises concerns about long-term reliability, security patches, and compatibility with newer AWS SDK versions.
  • Limited documentation
    The project's documentation is relatively sparse, lacking comprehensive examples, edge case handling guidance, and detailed API references, which can make it challenging for new users to adopt effectively.
  • AWS SDK version dependency
    The library depends on an older version of the AWS SDK for JavaScript, which may conflict with projects using the newer AWS SDK v3 and could miss out on performance improvements and features in updated SDKs.
  • Limited error handling flexibility
    The built-in error handling mechanisms are relatively basic, and handling partial failures or implementing sophisticated retry logic for individual object operations requires additional custom code from the developer.
  • Narrow scope of functionality
    The library is tightly focused on S3 object processing and does not integrate with other AWS services or provide utilities beyond basic map/filter/reduce operations, limiting its usefulness in more complex data pipeline scenarios.

Mind Diary features and specs

  • Mental Health Focus
    Mind Diary appears designed specifically to support mental health and emotional wellbeing, offering users a structured way to track moods, thoughts, and feelings over time, which can help with self-awareness and emotional regulation.
  • Simple Journaling Interface
    The platform likely offers an easy-to-use digital journaling experience, making it accessible for users who want to document their daily thoughts and mental state without complicated setup.
  • Progress Tracking
    By maintaining a diary over time, users can look back on entries to identify patterns in mood, triggers, or behaviors, which can be valuable for personal insight or discussions with therapists.
  • Privacy-Focused Personal Space
    A digital diary format provides a private, judgment-free space for users to express themselves, which can encourage more honest reflection compared to sharing with others.
  • Accessibility
    Being web-based (Irish domain .ie suggests local availability), it may be easily accessible to users in Ireland seeking mental health journaling tools, potentially at low or no cost.

Questions & Answers

As answered by people managing s3-lambda and Mind Diary.

Who are some of the biggest customers of your product?

Mind Diary's answer:

MindDiary does not currently publicly disclose individual customer or practice names.

What makes your product unique?

Mind Diary's answer:

MindDiary connects what happens before, during, and between therapy sessions in one workspace. Alongside practice management features such as digital intake, appointments, telehealth, invoicing, and therapist-reviewed AI notes, MindDiary helps therapists maintain continuity between sessions through client journaling, check-ins, homework, and session preparation. Instead of treating each appointment as an isolated event, MindDiary brings relevant client context together over time so therapists can prepare for sessions with a clearer picture of progress, concerns, and between-session activity. AI-assisted features support the therapist rather than replacing professional judgement.

Why should a person choose your product over its competitors?

Mind Diary's answer:

MindDiary is designed specifically around therapy workflows rather than being a generic scheduling or medical practice-management system. It combines digital intake, client management, session preparation, therapist-reviewed AI note drafting, telehealth, appointments, invoicing, revenue follow-up, journaling, homework, and between-session check-ins in one platform. A key difference is MindDiary's focus on between-session engagement and longitudinal client context. Therapists can use permissioned journal entries, check-ins, homework, recent sessions, and other relevant information to prepare for upcoming appointments instead of piecing context together across multiple disconnected tools.

How would you describe the primary audience of your product?

Mind Diary's answer:

MindDiary is built for counsellors, psychotherapists, therapists, psychologists, group practices, and therapy clinics. It is particularly suited to practitioners who want to reduce administrative work while improving continuity of care through digital intake, session preparation, clinical documentation support, client journaling, homework, check-ins, appointments, telehealth, and practice-management tools. MindDiary currently has a particular focus on therapy practices in Ireland and the United Kingdom, while the platform is designed to support therapists internationally.

What's the story behind your product?

Mind Diary's answer:

MindDiary was created around a simple observation: therapy software typically concentrates on what happens inside the appointment, while much of the useful context develops between sessions. Therapists often have intake information, notes, journals, homework, appointments, invoices, and client communications spread across different systems. MindDiary was built to bring these workflows together and make relevant longitudinal client context easier to use when preparing for the next session. The goal is not to automate therapy or replace clinical judgement. It is to give therapists a better workspace for understanding context, reducing administration, maintaining continuity between sessions, and running their practice.

Which are the primary technologies used for building your product?

Mind Diary's answer:

MindDiary is a modern cloud-based web application built primarily with React and TypeScript on the frontend and .NET/C# services on the backend. Its infrastructure uses technologies including AWS, Cloudflare, PostgreSQL, Stripe, and modern AI/LLM services. The platform is designed with security, privacy, scalability, and therapist control over AI-assisted workflows in mind.
