Sorushi vs ChatGPT for journaling: a general assistant, or a journal that asks first

ChatGPT can be a good place to reflect, and it has memory now. Sorushi is built only for journaling: it asks about each entry without being prompted. Here's the honest comparison.

You can journal in ChatGPT, and for many people it works well. Sorushi is different in one way that matters: it is built only for journaling. It keeps your entries as a dated journal and asks about each one without being prompted. ChatGPT waits for you to ask.

This is the honest comparison. When we asked ChatGPT to recommend an AI journal, it named itself among the options, and that is a fair answer. Facts about ChatGPT come from OpenAI's own pricing page and help center, checked on 26 October 2026. Both products change often.

What each one is built for

ChatGPT is a general assistant. It writes, researches, plans, codes, talks and analyzes. Journaling is one of thousands of things you can use it for.

Sorushi is a journal. You write an entry in your own words. Sorushi reads it, along with a selection of your earlier entries, your goals and recent patterns, and asks about the part you skipped past. Over time it finds patterns, notices goals that go quiet, and writes weekly and monthly reports.

So the question is not which AI is smarter. It is whether you want a tool that can do anything, or a journal that does one job.

What ChatGPT does really well

Some honest credit first, because it is deserved.

It is flexible. You can ask for hard questions, a summary, a reframe, a plan, or a different tone. You decide the format every time.

The free plan goes a long way. OpenAI's pricing page lists unlimited text chats on the free plan, subject to its usage guardrails. Go is $8 a month and Plus is $20 a month.

It has memory now. With Memory on, ChatGPT can use relevant details from past chats, saved memories and custom instructions. You can review a memory summary, correct it, or turn Memory off.

Voice and apps. ChatGPT has voice chats and apps on iPhone and Android as well as the web. Sorushi is text only, in a web browser.

Temporary chats. OpenAI says temporary chats do not create or update memories. That is useful if you want to think something through without it being remembered.

If you already use ChatGPT daily and like setting things up your own way, it may be all you need.

Where Sorushi is different

It asks first. After each entry, Sorushi asks one to three questions about what you wrote. You do not need a prompt or a template. In ChatGPT, nothing happens until you ask.

The past comes to you, on purpose. When Sorushi responds, it reads short excerpts from your latest entries and from around a month, three months and a year earlier. It uses them only when they connect to today. ChatGPT's memory is broader and less predictable by design. OpenAI says it does not retain every detail and looks for past context only when it is likely to improve a response.

Your writing stays a journal. Entries are kept by date, in journals you can search, tag and export. In ChatGPT, reflections sit among every other chat you have had.

Patterns and reports without asking. Sorushi looks for patterns in your recent entries and writes weekly and monthly reports. On Pro, it notices goals you mention and asks about the ones that go quiet.

No training on your writing. Sorushi uses Anthropic's API under terms that prohibit training on your content. OpenAI says it may use personal ChatGPT chats and remembered information to improve its models when "Improve the model for everyone" is on. You can turn that off in Data controls.

Privacy, honestly

Both encrypt your writing in transit and at rest. OpenAI's pricing page describes TLS 1.2 and AES-256. Sorushi encrypts entries at rest with AES-256-GCM.

The bigger difference is training. On personal ChatGPT plans, OpenAI's pricing page says content is used to train its models, with an opt-out available. Sorushi does not allow training on your writing at all, because its API terms with Anthropic prohibit it.

Neither offers end-to-end encryption. An AI has to read an entry to respond to it. If that is a hard requirement, a non-AI journal is the better answer.

Who ChatGPT is right for

ChatGPT is the right answer if any of these are true.

  • You already use it daily and want one tool for everything.
  • You like choosing the format of each reflection yourself.
  • You want to talk instead of type, or use a phone app.
  • You want occasional reflection, not a daily journal.

Who Sorushi is right for

Sorushi is the right answer if any of these are true.

  • You want a journal that asks the next question without being prompted.
  • You want your entries kept as a journal, not mixed into chats.
  • You want patterns, reports and goal follow-ups to arrive on their own.
  • You want a firm no on training, not an opt-out.

If that sounds like you, start a journal at Sorushi. It's free to start, and the first question shows up as soon as you finish an entry of any real length.

Can you use both?

Yes, and plenty of people do. ChatGPT suits open questions, planning and research. Sorushi suits the daily entry and the slow patterns that only show up over months.

The honest bottom line

ChatGPT is a brilliant general assistant that can also be a journal, if you set it up each time. Sorushi is only a journal, and it does that one job without being asked.

If you want flexibility, use ChatGPT. If you want a journal that asks and remembers on its own, choose Sorushi.

Frequently asked questions

Can I use ChatGPT as a journal?

Yes. Many people paste in an entry and ask ChatGPT for questions or reflections, and it does that well. It is a general assistant, though, so you set up the format each time, and your chats are not kept as a dated journal.

How is Sorushi different from ChatGPT for journaling?

Sorushi is built only for journaling. You write an entry and it asks one to three questions about it without being prompted, drawing on a selection of your earlier entries. It also finds patterns and writes weekly and monthly reports. ChatGPT waits for you to ask.

Does ChatGPT remember my past journal entries?

Partly. With Memory on, ChatGPT can use relevant details from past chats and saved memories. OpenAI says Memory does not retain every detail from every conversation, and that ChatGPT looks for past context only when it is likely to improve a response.

Does ChatGPT train on what I write?

It can, on personal accounts. OpenAI says it may use chats and remembered information to improve its models when the Improve the model for everyone setting is on, and you can turn that off in Data controls. Sorushi uses Anthropic's API under terms that prohibit training on your writing.

Which one costs less?

ChatGPT has a free plan, Go at $8 a month and Plus at $20 a month. Sorushi has a free plan that does not expire, and Pro is $8 a month, $72 a year, or $249 once. If you already pay for ChatGPT, journaling there adds no cost.

Can I use both?

Yes. Some people keep their journal in Sorushi and use ChatGPT for open-ended thinking, planning or research. The two do different jobs.
