Fillwarden vs Conveyor: security questionnaire tools
An enterprise prospect sends your team a security questionnaire. You have answered much of it before, but the responses are scattered across old spreadsheets. Choosing between Fillwarden and Conveyor starts with deciding how much of that process you want software to handle.
Fillwarden reuses answers you already wrote and puts them into the buyer's Excel file. Conveyor presents a broader customer-trust platform. For a founder, CTO or security lead at a small B2B SaaS company, the right choice depends on the work waiting in your inbox.
Atesen Software makes Fillwarden, so this comparison comes from one of the two vendors. We describe Conveyor only from its own website, which we re-opened and checked on 29 October 2026, and we state Fillwarden's limits too.
What each product is built to do
Fillwarden imports completed questionnaires into an answer library in your browser, matches the questions in a new file against that library, and copies the answers you wrote before into the buyer's workbook. It shows the past question behind each suggestion and a match score. It does not write new answers with AI. See the Fillwarden site.
Conveyor's website presents AI questionnaire automation alongside a Trust Center, AI-powered knowledge management and AI RFP responses. Consider that broader scope if your buying decision covers customer trust beyond completing spreadsheets.
| Buying question | Fillwarden | Conveyor |
|---|---|---|
| Where should you begin? | Test reuse of your past answers in a new spreadsheet | Assess the wider customer-trust workflow |
| How are answers produced? | Copied from your own library; a row with no match stays blank | Conveyor describes AI questionnaire automation |
| Is a trust center included? | No | A Trust Center is listed among Conveyor's products |
| RFP responses and knowledge management? | No | Both are listed among Conveyor's products |
| What is the price? | Free plan; Pro is $29 per month or $290 per year, plus any tax | Check current pricing |
These are different scopes, so a longer feature list alone does not decide which tool suits your next questionnaire.
How Fillwarden handles your spreadsheet
Start with a completed Excel (.xlsx) or CSV questionnaire. Fillwarden finds the question and answer columns, and you can change the mapping before it matches. Importing past files builds a library you can search and reuse.
Next, open the buyer's questionnaire. Fillwarden works on spreadsheets with one question per row. It can write a short Yes/No response into one column and the explanation into another. Section titles and rows that already contain answers are left alone. Questionnaires over 5,000 rows are refused rather than cut short.
The review screen separates Strong match, Check and No match rows. Each suggestion shows the past question it came from and a match score, and rows with no match stay blank. You can edit any answer before you download, and by default the answers you type or change are saved to your library.
The download writes into a copy of the buyer's workbook and keeps sheets, formatting, column widths and dropdowns. Charts and macros may not be kept, so keep the original file and inspect the output. PDF and Word questionnaires are not supported, and an older .xls file must be saved as .xlsx first.
Privacy and collaboration tradeoffs
Fillwarden reads and writes your spreadsheets in your browser and stores the answer library in that browser's local storage. Questionnaires and library answers are not uploaded. For Pro, the app sends your license key to check it; payment is handled by Paddle. The privacy policy describes these data flows.
Local storage makes browser housekeeping part of your workflow. Clearing your browser data deletes the library, so export a CSV backup. Teammates can share a library by exporting it as CSV and importing it in their own browser, but Fillwarden does not sync a shared library.
If central collaboration is a purchase requirement, list the exact behaviours you need and verify them during your evaluation. A company licence and a synchronised workspace are different requirements.
Pricing
Fillwarden's free plan has no account and no card. It includes an unlimited answer library and matching and review for every question, but each downloaded file gets only the first 20 answers. Pro writes every matched answer and costs $29 per month or $290 per year, plus any VAT or sales tax Paddle adds. One subscription covers your company and its staff, using the license key in each teammate's browser.
Pro subscriptions renew automatically until you cancel, and every charge can be refunded in full within 14 days under the refund policy. See Fillwarden pricing.
For Conveyor, check current pricing, and compare the package you actually need rather than assuming both products cover the same work.
Which should your team choose?
Choose Fillwarden when you already have useful answers and want to reuse them in incoming Excel or CSV questionnaires. Its source questions and editable suggestions let you inspect what goes back to the buyer.
Consider Conveyor when your evaluation includes a trust center, knowledge management or AI-written answers. Confirm the features, package and data requirements directly with the vendor.
Questions
Can Fillwarden replace an entire compliance platform?
No. It does not provide a trust center, security audit evidence or compliance monitoring. Its job is to reuse your own answers in questionnaires.
Does a strong match mean the answer is still true?
No. Similar wording does not prove that your controls are unchanged. Check every response for accuracy and currency before you send it.
Does Fillwarden use AI to write answers?
No. It compares the wording of each new question with the questions in your library, using a matcher that knows security vocabulary such as MFA and 2FA, and copies the answer you wrote before. If nothing fits, the row stays blank.
