If Claude is your default,docAnalyzer is the workspace around it.
Claude Projects gives you long-form Claude on a small file set. docAnalyzer runs Claude alongside 29 other models, plus the workflows, downloadable files, and citation infrastructure that turn a chat into shippable work.
No credit card. Free tier covers everyday Q&A.
Claude's reasoning is great. The workspace around it is where the work lives.
Claude Projects is a system prompt + a file uploader + Claude. That works for one-shot Q&A or focused conversational analysis. It doesn't work when the deliverable is a structured spreadsheet, when the dataset has 50 documents, or when the cited claim has to open the page in one click.
You don't need to leave Claude to get those things. You need a workspace that runs Claude alongside the rest of the toolkit.
Claude Projects
docAnalyzer
Model choice
Claude only.
30+ models including Claude. Switch mid-thread without losing the active work.
Batch workflows
None. Conversational chat only.
Six workflows run across every source in a dataset and return a structured result.
Reusable file outputs
Markdown answers. No native PDF, spreadsheet, or chart generation.
The model produces real PDFs, XLSX, HTML, charts, diagrams: downloadable as chips, reusable across turns.
Multi-doc datasets
Files uploaded to a single project. No labels, no cross-project organization.
Workspaces with documents, notes, labels. Datasets are built from any combination, persistent.
Citation discipline
Citations are conversational: Claude tells you what it's referring to in prose.
Cited claims are clickable references that open the source at the exact page or section. Enforced by the engine, not requested as a behavior.
In their own words
“Much better than others that specialize in document analysis. docAnalyzer not only allows reading larger documents but also produces broader results. Choosing the model you want is another advantage since each model has its strengths depending on your needs.”
Raul Figueroa (Product Hunt)
What Claude Projects users push on hardest.
Claude's reasoning is the best in the business. Why use anything else?
docAnalyzer runs Claude. You get Claude when Claude is best, and you don't lose your work when you switch to a model better for extraction, structured output, or speed. One plan, every frontier model.
I'm already paying for Claude.ai. I don't want a second subscription.
Many docAnalyzer users keep Claude.ai for general-purpose conversational work. docAnalyzer is the document workspace on top: workflows, downloadable files, citation infrastructure that don't exist in Claude Projects at any tier.
I trust Anthropic on safety more than a startup.
docAnalyzer's per-tenant isolation means your content never trains any model: Anthropic's or anyone else's. The safety boundary is in the architecture, not in the brand.
Claude Pro is $20/mo and I'm already paying for it.
docAnalyzer's free tier covers everyday Q&A; paid tiers run alongside your Claude subscription, not instead of it. The right framing isn't "switch from Claude"; it's "add the workspace Claude doesn't have."
Frequently Asked Questions
Do I have to give up Claude?
No. Claude models are in the catalogue alongside more than thirty others, and you can switch mid-thread without restarting the agent or losing the active work. A Claude Project is Claude only; here it is one option among many.
What does docAnalyzer add that a Claude Project does not have?
Batch workflows that run across every source in a dataset, real file outputs you can download, labels and workspaces that persist across projects, and citations that resolve to an exact page. A Claude Project is a good place to keep files and talk about them. It is not built to produce work.
Do I get files back, or just answers?
Files. A turn can produce a real PDF, spreadsheet, HTML page, chart or diagram, downloadable as a chip and reusable in later turns. Claude Projects returns markdown you copy out by hand.
How is my material organised?
Workspaces hold documents, notes and labels, and a dataset can be built from any combination of them and reused across chats. Claude Projects keeps files inside a single project with no labels and no organisation across projects.
How large can a document be?
Between 20 MB and 500 MB per file depending on your plan, with per-seat storage from 100 MB up to 50 GB. Fifteen formats are accepted, including PDF, DOCX, PPTX, XLSX, EPUB, ODT, RTF, HTML and plain text. The compare plans page lists the figure for each tier.
Are my documents used to train AI models?
No, on every plan including the free one. Documents are encrypted at rest with AES-256, isolated per tenant by row-level security, and deleted when you delete them. The security page sets out who processes what and where.
