About Long Summary
What Is Long Summary
Long Summary is a web tool from the software company MB Skydis that compresses long texts into summaries sized the way you want them. Most AI chat assistants taper off when a document runs to hundreds of pages, and they rarely produce a long summary on purpose. Long Summary takes the opposite angle. You paste a text or upload a file, set how long you want the result to be, and it produces a summary at that length, whether that's a short recap or a detailed breakdown that keeps most of the source intact.
The problem it targets is a real one for anyone who works with big files. Legal contracts, research papers, meeting transcripts and technical reports often run far past what a general chatbot handles well, and a one-paragraph summary of a 200-page document drops most of what matters. Long Summary keeps the detail that a short summary would throw away, which is the whole point of a custom length summary.
Two limits are worth knowing up front. The service runs on the OpenAI API, so the quality of each summary tracks whatever underlying model it calls, and MB Skydis writes in its own terms of service that it makes no guarantees about accuracy. The site also gives no self-hosted option: you work in the browser, on their servers, and the developer API is the only way to wire it into your own product.

Key features
Custom Length Summaries
Long Summary lets you decide how long the output should be rather than fixing it at a handful of sentences. You can ask for a brief overview or a long, detailed analysis of the same source text, and the tool scales the summary to that target. For anyone who needs the middle ground between a teaser and the full document, this is the feature that sets the tool apart from a standard chatbot.
No Input or Output Size Limits
The site states that it has no limits on input and output size, which is the claim behind the name. Where a general assistant might handle a few dozen pages before it starts to lose detail, Long Summary says it can take texts running to millions of characters. That matters for contracts, transcripts and reports that would otherwise need splitting into chunks the tool would summarize out of context.
File Uploads
Instead of pasting text into a box, you can upload the file you want shortened. The tool accepts document uploads and returns a summary at the length you choose, which saves the copy-and-paste step on long files. It's aimed at the everyday case of a report or a transcript you already have as a file and would rather hand over whole.
AI-Powered Accuracy
The summarizer runs on AI to produce coherent summaries that read as connected prose rather than stitched-together fragments. MB Skydis builds the product on the OpenAI API, so the summaries follow the quality of the models that API serves. The company also states plainly in its terms that it makes no guarantees about accuracy, so the output is a starting point, not a verified record.
Developer API
Long Summary offers an API for developers who want to build the summarization into their own applications. Rather than opening a browser tab each time, a team can send texts and files to the engine programmatically and use the results inside a product. The company lists this as a core selling point, aimed at agencies and product teams that already automate parts of their content work.
Privacy-First Handling
The privacy policy says the service doesn't collect or store the content you upload. Text is processed through the OpenAI API, uploaded files are kept only as long as needed for processing and then deleted, and nothing is shared with third parties apart from OpenAI for the summarization itself. Sign-up collects just an email, a name and your plan and credit balance, and payments run through Stripe so no card details sit with MB Skydis.
Pros and cons
Pros
- Summaries are sized to what you need, from a short recap up to a long and detailed one, so you keep the detail a fixed-length summary would drop
- The site advertises no limits on input or output size, which suits very long contracts, papers and transcripts
- File uploads cut the copy-and-paste step on documents you already have
- A developer API lets teams run the same summarization inside their own apps
- The service states it doesn't store uploaded content and deletes files after processing
Cons
- It runs on the OpenAI API, so summary quality depends on the underlying model and can shift over time
- The company's own terms make no guarantees about accuracy, so output still needs a human check
- Pricing for the paid subscription and credits isn't published up front, so you only learn the cost on the site after signing up
- No self-hosted option, which means every document you summarize goes through their servers and OpenAI
