For people whose files no longer fit in one project
ChatGPT Projects Alternative for All Your Documents and Client Files
Short answer: a ChatGPT project holds 25 files on Plus and 40 on Pro, Business and Enterprise. That is plenty for one task and far too few for ten years of proposals, reports and transcripts. MentalClone is a private library with no cap on how many documents you keep on Starter or Professional. It answers only from those files, in your own voice, and says so when they do not cover a question. From $24 a month billed yearly.
Paste a page from one of your own reports into the box and ask it a question. Three questions, no account needed.

Why people look for a ChatGPT Projects alternative
Projects are a good way to keep one piece of work together: a set of chats, a few reference files and some instructions. The trouble starts when you try to use a project as the place where all of your knowledge lives.
The file cap fills in an afternoon
Twenty-five files is one client engagement. A consultant with forty past clients ends up splitting work across projects and guessing which one holds the answer.
Every new project starts empty
Files belong to the project they were uploaded to. Start a new project and you upload your methods deck and templates all over again.
Your clients do not have ChatGPT seats
A project is shared with people who sign in to ChatGPT. The client who just wants an answer from your playbook cannot ask it without an account.
It fills gaps with general knowledge
Ask something your files do not cover and ChatGPT will still answer from what it knows. Useful for brainstorming, risky when a client takes it as your advice.
ChatGPT Projects alternatives compared on files, sharing and price
US list prices. The columns that decide it for most buyers are the file cap and who can ask the thing once it is set up.
| Tool | Price | Files you can keep | Who can ask it | When files do not cover it |
|---|---|---|---|---|
| ChatGPT Plus, Projects | $20 a month | 25 per project, 512 MB per file | You, and people you share with who sign in to ChatGPT | Answers from general knowledge |
| ChatGPT Pro, Projects | From $100 a month | 40 per project | Same as Plus | Answers from general knowledge |
| Custom GPT | Included with paid ChatGPT | 20 knowledge files per GPT | Anyone with a ChatGPT login and the link | Depends on your instructions |
| Claude Projects | Claude Pro $20 a month, $17 billed yearly | Up to 30 MB per file, bounded by the context window | Your Claude Team or Enterprise workspace | Answers from general knowledge |
| MentalClone Starter | $49 a month, or $288 a year ($24 a month) | No document cap, 100 MB per file | You, plus clients through private links with no account | Says your files do not cover it |
Project file caps from OpenAI's announcement of Projects for all plans (5 Free, 25 Plus, 40 Pro, Business and Enterprise); per-file and instruction limits from OpenAI's file upload and Projects help pages. Claude prices from claude.com/pricing. Vendors change limits often, so check your own account before you decide.
One library instead of a project per client
In ChatGPT you decide up front which 25 files go into which project, and every question only sees that set. MentalClone keeps everything you upload in one library. When you ask something, it picks the documents that actually match the question from the whole archive, reads the relevant passages and answers from them.
It writes in the first person and in the register of your own documents, so a client reading the answer hears you, not a generic assistant. If nothing you wrote covers the question, the answer says that plainly.
- Upload PDF, DOC, DOCX, XLSX, CSV, RTF, TXT, Markdown, EPUB, saved emails, PowerPoint, scans and phone photos.
- Bring a zipped Obsidian, Logseq, Bear or Notion export, up to 2,000 notes per import.
- Revoke any client link in one click when the engagement ends.

How to move your project files in four steps
Keep your ChatGPT subscription while you try it. Most people run both side by side for a few weeks.
Collect the originals
Projects keep your uploads, but your originals are usually still in Drive, Dropbox or a client folder. Gather those, not just the 25 you picked.
Upload the whole archive
Drop in every proposal, report, transcript and note you reuse, up to 100 MB per file. No sorting into projects first.
Ask last week's questions
Run three questions you asked ChatGPT recently. Where the answer says your files do not cover it, you have found a gap in what you wrote down.
Share with one client
Create a private link for a client who asks the same things every month. They ask, you stop answering the same email.
Who switches from ChatGPT Projects
People who sell what they know and have more of it written down than any one project can hold. They usually keep ChatGPT for drafting and use MentalClone as the source of truth.
Independent consultants
Every engagement report and proposal in one place. Ask how you solved a problem before and get your own answer, not a textbook one.
Coaches and trainers
Workbooks, session notes and frameworks behind one private link per client, so questions between sessions get answers in your method.
Agency owners
Playbooks, SOPs and past client deliverables that new hires can question without pinging you, and without each of them buying a seat.
Lawyers, advisors and analysts
Memos and research you wrote, answered strictly from your text, with a clear note when your files are silent on a point.
When ChatGPT Projects is still the better buy
We would rather you keep the right tool. Stay with Projects if one of these describes you.
Your work fits in 25 files
One project per deliverable with a handful of references is exactly what Projects does well, for $20 a month.
You want web search and images
ChatGPT browses, codes, draws and analyzes data. MentalClone only answers from your documents.
You need answers beyond your files
If you want the assistant to fill gaps from general knowledge, that is ChatGPT's strength and our deliberate limit.
Your team already pays for Business
Shared projects inside a ChatGPT Business workspace may cover internal use without another subscription.

ChatGPT Projects alternative questions
What is the best alternative to ChatGPT Projects?
+
It depends on what outgrew the project. If you just want another general assistant with project folders, Claude Projects is the closest match. If the problem is that your documents no longer fit in 25 or 40 files, or that clients without ChatGPT accounts need to ask them, a document library like MentalClone fits better because it has no document cap on Starter and shares by private link.
How many files can you upload to a ChatGPT project?
+
OpenAI allows 5 files per project on Free, 25 on Plus and Go, and 40 on Pro, Business and Enterprise. Each file can be up to 512 MB, and paid plans can upload about 80 files every three hours. When a project is full you have to remove a file before adding another.
Can I share a ChatGPT project with someone who does not have ChatGPT?
+
No. The people you share a project with sign in to ChatGPT to use it. If you want a client to ask your documents without creating an account, MentalClone gives each client a private link with up to 100 questions a day, and you can revoke it at any time.
Is ChatGPT Projects worth it for a consultant?
+
For one engagement at a time, yes. At $20 a month on Plus you get project folders, custom instructions and 25 reference files. It gets awkward once your reusable knowledge spans dozens of clients, because every project starts empty and only sees the files you put in it.
Does ChatGPT use only my project files to answer?
+
Not strictly. ChatGPT reads your project files and instructions but also answers from its general training when the files are silent. MentalClone is built the other way round: it answers only from your uploaded documents and tells you when they do not cover the question.
How much does a ChatGPT Projects alternative cost?
+
Claude Pro is $20 a month or $17 billed yearly. MentalClone Starter is $49 a month or $288 a year, which works out to $24 a month, and Professional is $99 a month or $588 a year. You can ask three questions in the demo on this page before you pay anything.
Can I move my ChatGPT project files to MentalClone?
+
Yes. Upload the original files from your computer or cloud folder: PDF, Word, Excel, CSV, PowerPoint, Markdown, EPUB, emails and scans are all read, up to 100 MB each. Chat history inside ChatGPT does not transfer, but the documents behind it do.
Put every file you wrote in one place you can ask
Upload the archive that never fit in a project and ask the question you could not answer last week.
