Zephior vs Stargazy
Move from provider research to files Ziva can produce.
Choose Ziva when you are ready to have the supplier response made: original buyer documents, calculations and supporting deliverables. Stargazy helps teams discover and evaluate providers. Its directory can inform the purchase, while Ziva performs a different job in the bid itself.
Where Ziva makes the difference
Get more of the work off your team’s desk.
Have the agent produce the actual package
Ziva can fill the original workbook, revise the technical narrative and create annexes or slides. She can change formulas, tables and layout. The result is editable response work rather than another listing or review of tools that might help.
Start with company evidence and a reusable method
Build knowledge from existing documents and diagrams and retain terminology and repeatable preparation instructions with Ziva. The next tender can reuse both company evidence and working standards instead of beginning with another blank assistant session.
Evaluate a produced result, not a ranking
Use the same real tender and compare the files, evidence, review controls and remaining customer effort. Ziva offers source-scoped participation and accepted document history; test those behaviors. This is a Zephior-authored comparison, not an independent ranking of the marketplace.

Follow the work, stage by stage.

Remember
Reuse company evidenceCategory learning differs from your company’s governed bid evidence library.
Turn existing documents and diagrams into reusable company evidence. Select the sources for each bid, review proposed knowledge changes and carry company terminology and working instructions into later assignments.
Respond
Produce the actual filesA provider listing does not itself prepare your tender answers. Confirm the actual delivery provider.
Stargazy third-party managed-services listings(opens in a new tab)Give Ziva the buyer’s original files and the outcome. She can fill workbook cells, revise document content and layout, build calculations and prepare related Word, Excel, PDF and presentation deliverables.
Review and deliver
Move to approved outputAgree final files, approval and submission directly with the provider commissioned for the bid.
Keep source-scoped reviewers, comments and accepted document history beside production. Review and restore prior accepted versions. Zelius can handle separately agreed submission work with customer approval and authority.

Pricing and ownership
Price the work completed, not just the subscription.
Stargazy
The reviewed site advertises a free report and provider listings; no universal fee for an outsourced bid was established. Confirm community or directory access and any listed provider’s own commercial terms separately. A free research resource is not a free managed response.
