Easy Dataset
Open-source, project-based tool for turning your documents into QA datasets for LLM fine-tuning.
Easy Dataset is a real pipeline, not a wrapper: chapter-aware chunking, the two-level domain tree, and interrupt/resume batch generation are engineering decisions that change your output quality, not decoration. If you have a pile of Markdown documents and a fine-tuning run to feed, the literature-to-QA-pairs path is the reason to use it, and reasoning-model support lets you generate COT answers without hand-building them. Compare before committing: Argilla is the stronger choice when annotation workflow and human review are your center of gravity, and LlamaFactory's own data tooling may be enough if you only need Alpaca output.

Skip Easy Dataset if your work is human annotation and review workflow rather than document-to-dataset generation, or if you need a no-code interface and do not read Chinese.
Generation runs on your own model credentials, so every QA pair you produce is billed by your OpenAI-format provider or consumes local GPU time on Ollama
Easy Dataset is an open-source project, so license cost is not the comparison point — your spend is the model usage behind generation. Teams paying per-token to OpenAI or DeepSeek should weigh that against a local Ollama model, which trades throughput for no per-call cost. Compare total cost of ownership against Argilla (annotation workflow) and LlamaFactory's bundled data tooling before adding another step to your pipeline.

About Easy Dataset
Easy Dataset is an open-source, project-based tool for turning your own documents into question/answer datasets you can use to fine-tune large language models, build RAG systems, and run evaluations. Each project walks a document through a full pipeline: chapter-aware recursive chunking that splits Markdown by structure (with configurable minimum and maximum block length), AI-assisted question generation driven by configurable character density, answer construction that can use reasoning models for chain-of-thought output, two-level domain label generation (for example Sports → Football) with manual correction, quality checks, and export to Alpaca or ShareGPT with custom field mapping. It addresses the problems teams hit doing this by hand: a single giant file produces poor QA pairs, context windows cap how much you can generate at once, and generating in batches produces near-duplicate questions. Easy Dataset answers these with interruptible and resumable bulk question generation, per-question character-density control, and a domain tree that holds duplication down. A model configuration center handles OpenAI-format APIs (OpenAI, DeepSeek, other providers) and local models through Ollama, with a built-in playground for multi-model comparison. A dataset marketplace aggregates sources from HuggingFace and Kaggle to solve the 'where does my data come from' starting problem. It is built for developers, data scientists, and AI researchers who want automated dataset creation with real quality control rather than a prompt wrapper. Note: the project's documentation is primarily written in Chinese.
Behind the Verdict
Most dataset tools fail at the same two places, and Easy Dataset was built around those failures. The first is chunking: hand a single large Markdown file to a model and the QA pairs it returns are shallow and repetitive, so Easy Dataset splits documents with a chapter-aware recursive algorithm that follows Markdown section structure and lets you configure minimum and maximum block length. The second is duplication at scale: because a model's context window limits how many questions you can generate in one pass, batched generation drifts toward asking the same thing twice, so Easy Dataset generates questions per text block by character density and attaches each pair to a node in a two-level domain tree (Sports → Football) that keeps generation anchored to a specific subdomain. That tree is auto-generated and manually correctable, which matters because it is the label your dataset carries into multi-task fine-tuning. Where it earns its keep beyond chunking is the generation and quality loop. Bulk question generation can be interrupted and resumed, so a long run is not a single fragile sitting; answers can be built against the original text block and produced with chain-of-thought output through reasoning models such as DeepSeek-R1; and pairs can be bulk-deleted, hand-edited, or polished by an AI instruction pass. Export covers Alpaca and ShareGPT with custom field mapping and can carry domain labels and COT information through to the training framework. The project-based structure means one project tracks a document from ingestion to export, and the dataset marketplace pulls in HuggingFace and Kaggle sources when you need a starting corpus rather than a conversion. The honest limits: every generated pair comes from whichever model you configured — an OpenAI-format API provider or a local Ollama model — so both quality and cost are a function of that choice, not of the tool. Chapter-aware chunking reduces context-window truncation but does not eliminate the need for a manual pass on very large or badly structured documents. The documentation is primarily Chinese, which is a real barrier for teams that do not read it. And if your work is human annotation workflow with review queues, Argilla is the more natural home; if all you need is Alpaca output to feed LlamaFactory, its own data tooling may already cover you. Easy Dataset is strongest when dataset construction itself is the bottleneck — a research group with domain literature and a fine-tune to feed, or a developer who needs labeled, deduplicated, COT-capable pairs exported to a specific framework format.

Real-world workflow fit
Concrete scenarios for the personas Easy Dataset actually fits — and what changes day-one when you adopt it.
You drop a folder of Markdown research papers into a new Easy Dataset project, let chapter-aware recursive chunking split them by section with a configured block length, then run bulk question generation by character density and build answers with a reasoning model for COT output.
Outcome: You get a labeled QA dataset exported in Alpaca format with custom field mapping, ready to hand to a fine-tuning run without hand-writing questions.
You rely on the auto-generated two-level domain tree (Sports → Football) to tag every pair, correct the labels by hand where the AI guessed wrong, and use batch delete plus AI polishing to clear weak pairs.
Outcome: A deduplicated, hierarchically labeled dataset you can split by subdomain for multi-task fine-tuning.
You search the dataset marketplace for HuggingFace and Kaggle sources to seed a project, then let Easy Dataset generate additional domain-tagged pairs against those documents, interrupting and resuming the batch run as needed.
Outcome: A training and evaluation set built from a starting corpus instead of an empty directory, exported to ShareGPT for your RAG pipeline.
Use Cases
- Convert a set of research papers into QA pairs for fine-tuning a domain-specific model.
- Generate chain-of-thought training data for a reasoning model using DeepSeek-R1.
- Build labeled datasets with hierarchical domain tags for multi-task fine-tuning.
- Export a dataset in Alpaca format for a LlamaFactory training run.
- Aggregate HuggingFace and Kaggle sources into one project before generating new pairs.
Models Under the Hood
as of 2026-10-09
Limitations
- Easy Dataset generates content through external model APIs (OpenAI-format providers, DeepSeek) or local models via Ollama, so quality and cost both depend on the model you configure.
- The chapter-aware chunking mitigates context-window limits, but very large or poorly structured documents may still need a manual pass.
- The documentation is primarily in Chinese, which is a usability barrier for non-Chinese-speaking teams.
- It is aimed at people doing dataset construction work, so it is not a fit for non-technical users who want a no-code dataset builder.

Where the pricing makes sense
The company stage and team size where Easy Dataset's pricing actually pencils out — and where peers do it cheaper.
Easy Dataset is an open-source project, so license cost is not the comparison point — your spend is the model usage behind generation. Teams paying per-token to OpenAI or DeepSeek should weigh that against a local Ollama model, which trades throughput for no per-call cost. Compare total cost of ownership against Argilla (annotation workflow) and LlamaFactory's bundled data tooling before adding another step to your pipeline.
Setup time & first value
How long it actually takes to get something useful out of Easy Dataset — broken out by persona, not the marketing-page minute.
For a developer already holding OpenAI or DeepSeek credentials, first value is quick: configure the model endpoint in the configuration center, create a project, and run chunking plus one question-generation batch inside a single sitting. Teams without API keys need time to stand up Ollama and pull a local model first. Budget extra hours for chunk-size tuning on large or messy documents, and

- →From manual spreadsheet QA writing: import your Markdown documents into a project and let chunking plus bulk generation replace the manual pass
- →From a raw script calling the model on whole files: move to chapter-aware chunking so each block stays semantically complete
- →From HuggingFace or Kaggle datasets alone: pull the source into a project via the dataset marketplace, then generate new labeled pairs against it
- →From another dataset format: use custom field mapping on export to reach Alpaca or ShareGPT
- ↗To Argilla: export your generated pairs, then re-import them as records when annotation workflow and human review become the priority
- ↗To LlamaFactory: export in Alpaca format with field mapping and feed the file directly into its training data loader
- ↗To a custom RAG pipeline: export to ShareGPT and load the JSON into your own ingestion step
