Simplify Copilot is the default recommendation on every "best autofill extension" listicle right now, and for good reason: its free tier is genuinely useful and its brand is well-known among active job seekers. But "well-known" and "best fit for your workflow" are different things. If you have tried Simplify and found yourself hitting walls — the premium price for AI question answers, no place to store your actual documents, no mobile access, or fill quality that degrades on the enterprise ATS systems most large companies use — there are alternatives worth understanding.
This post compares Simplify Copilot with ProfVault across the dimensions that matter most for a high-volume job search: fill accuracy on the big ATS systems, what the free tier actually unlocks, document handling, and platform availability. It is not a takedown; it is a comparison to help you pick the tool that fits your search.
What Simplify does well (and where its free tier actually stops)
Simplify's free tier covers the broadest range of job boards for basic autofill — the extension detects forms on LinkedIn, Indeed, Greenhouse, Lever, Workday, and most others and prefills standard fields like name, email, phone, and address from a stored profile. The job tracker is solid, the UI is clean, and the Chrome rating is high. For job seekers who want to get started quickly and apply volume without paying anything, it is a reasonable first choice.
The gaps show up when the search gets serious:
- AI-tailored answers to custom application questions are behind Simplify+. The free tier fills standard fields but leaves free-text questions — "Why do you want to work here?", "Describe a time you led a team" — for you to answer manually every time.
- No document vault. Simplify does not store your resume, cover letter, certifications, or portfolio. It generates or reformats documents, but the source of truth still lives in your Google Drive or local folders.
- No mobile app. Simplify is Chrome extension only. If you browse job postings on your phone — and most job seekers do — you cannot apply from there.
- Per-ATS fill intelligence is shallow. Simplify fills fields it recognizes by label. On Workday's multi-step wizard or on iCIMS portals that re-ask questions your resume already answered, the fill quality is field-by-field rather than workflow-aware.
- Simplify+ is $40/month if billed monthly. That is not a free alternative with an optional upgrade — it is a free tier with a high paywall for the features that close the loop.
None of these are dealbreakers for everyone. But if any of them describe your current pain point, Simplify is probably not the right long-term tool.
How ProfVault's autofill actually works differently
ProfVault's core bet is that autofill accuracy improves when the fill engine understands your complete professional history — not just a flat profile with name and email, but your full work history, education, projects, skills, languages, and stored documents, all indexed with vector embeddings so the matching is semantic rather than label-based.
When you install the ProfVault Chrome extension and visit a job application form, the extension sends the detected form fields to ProfVault's API. The backend runs those fields through a RAG pipeline — Retrieval-Augmented Generation using your profile embeddings — to find the best match from your actual stored data, not a static form-field lookup table. The result is that fields Simplify typically leaves blank or fills incorrectly (job-specific descriptions, employer names in non-standard label formats, custom screening questions that map to things you have genuinely said about yourself) get filled from what you actually wrote in your profile.
The ATS-specific detail matters on the platforms where fill quality drops the most. Workday, for instance, spreads a single application across five to eight screens with its own navigation model. ProfVault's Workday autofill page explains how the extension handles the My Information, My Experience, and Application Questions steps progressively — each screen is filled as you navigate to it, not in one pass that misses later pages. The same platform-aware logic applies to Greenhouse, Lever, iCIMS, Taleo, and the other high-volume ATS systems where generic fill breaks.
What the free tier covers — and where ProfVault's paid tier sits
ProfVault's free tier includes 5 welcome credits when you sign up, which covers form fills, resume generation, and cover letter generation. The monthly plan is $9/month (or ₹299/month for Indian job seekers, €8/month in Europe), and the annual plan is $49/year — roughly $4/month. There is no equivalent of Simplify+'s $40/month tier; the $9 plan is the only paid plan.
For comparison:
| ProfVault Free | ProfVault $9/mo | Simplify Free | Simplify+ | |
|---|---|---|---|---|
| Basic autofill (name/contact/address) | Yes | Yes | Yes | Yes |
| AI-tailored custom question answers | Limited (credits) | Yes | No | Yes |
| Document vault (resume, certs, portfolio) | Yes | Yes | No | No |
| Mobile app (iOS + Android) | Yes | Yes | No | No |
| ATS-specific fill workflows | Yes | Yes | Partial | Partial |
| Price | Free | $9/mo | Free | $40/mo |
The document vault difference is worth dwelling on. ProfVault's profile is not a form you fill out once and forget — it is a structured store of your full professional history that the autofill engine pulls from at fill time. Uploading your resume to ProfVault parses it into structured experience, education, and skills entries. You can upload certifications, portfolio work, or cover letters and have them referenced during applications. Simplify has no equivalent; it generates documents in-session but does not store the source material.
Platform availability: the mobile gap
Active job seekers increasingly browse postings on mobile. Neither Simplify nor most autofill tools have a mobile autofill story — the Chrome extension model does not translate to iOS Safari or Android Chrome in a meaningful way for form filling. ProfVault's approach here is different: the mobile apps (iOS and Android, both available now) give you access to your full profile, stored documents, resume generation, and interview prep on mobile. The autofill extension is still Chrome-only for the actual form-filling action, but you are not locked out of your profile or document vault when you switch devices.
For job seekers who use their phone to research roles and desktop to apply, this matters: your ProfVault profile is the same whether you add a note on mobile or fill a form on desktop.
ATS coverage: the platforms where it actually matters
Both tools cover the mainstream platforms. The difference shows up on the enterprise and mid-market ATS systems where generic fill breaks most often:
- Workday: ProfVault's fill handles the multi-step wizard progressively; Simplify fills what it recognizes on each step but may leave navigation-dependent fields blank.
- iCIMS and Taleo: These older systems use non-standard field names and session-dependent form state. ProfVault's ATS-specific detection handles the duplicate re-entry these systems force (uploading a resume and then retyping it into structured fields), which is where most autofill tools give up.
- Ashby and Greenhouse: Both tools cover these well. ProfVault's advantage here is answering recurring custom questions (work authorization, salary expectations, "how did you hear about us") from saved profile answers rather than leaving them blank.
If your search is concentrated in startups using Greenhouse and Lever, the difference in fill quality is marginal. If you are applying to Fortune 500 companies using Workday, iCIMS, or SuccessFactors, the gap is real.
Where ProfVault fits in your workflow
The honest framing: ProfVault is not strictly a Simplify replacement — it is a different tool with a broader scope. Simplify is focused on fast, breadth-first autofill across as many job boards as possible. ProfVault is focused on fill accuracy from a complete professional history, with document storage and mobile access as parallel utilities.
If you use both, you would use Simplify for the quick-apply volume and ProfVault for the applications that require a complete work history (large company ATS, applications with custom screening questions, anywhere you want your actual stored resume attached rather than a regenerated version).
If you want one tool: ProfVault covers the autofill use case, stores your source documents, handles mobile, and costs $9/month (or $49/year) rather than $40/month for the features that matter. The free tier with 5 welcome credits is a real trial, not a locked preview.

FAQ
Is ProfVault's autofill actually free?
Yes. ProfVault's free tier includes 5 welcome credits on signup, which you can use for form fills, resume generation, or cover letters. Basic autofill on standard fields (name, email, phone, address) does not consume credits — credits are used for AI-generated answers to custom questions, resume generation, and cover letter generation. The Chrome extension download and basic fill are free without an account upgrade.
Does ProfVault work on the same job sites as Simplify?
ProfVault's extension works on 80+ ATS platforms including Workday, Greenhouse, Lever, iCIMS, Taleo, Ashby, SmartRecruiters, BambooHR, SAP SuccessFactors, Jobvite, and most major job boards. The full platform list includes per-ATS guides with exactly which fields are filled on each system.
What happens to my resume and documents in ProfVault?
Documents you upload are stored in your ProfVault vault and processed by the AI document analyzer to extract structured data (work history, education, skills). The structured data populates your profile, which the autofill engine uses. Your original files are stored and accessible. Simplify does not offer document storage — it generates documents in-session but does not retain your source material.
Will ProfVault auto-submit my applications?
No. ProfVault fills form fields from your profile data, but the submit action is always yours. The extension shows you what it filled before you submit, and you can edit any field before sending. Auto-submission is not a feature any responsible autofill tool should offer — application submissions carry your name and signature.
Does ProfVault work on Firefox or Safari?
ProfVault has a Firefox extension in addition to the Chrome extension. The Safari extension is in development. The iOS and Android mobile apps give you access to your profile and documents on those platforms, though in-browser form fill on mobile Safari is not yet supported.
Is ProfVault's $9/month plan significantly better than the free tier?
The free tier is a genuine trial with 5 credits. The $9/month plan gives you 10 credits per month, which covers roughly 10 full AI-assisted application fills or a mix of resume generation, cover letters, and form fills. If you are running a high-volume search (20+ applications per month), the paid tier makes sense. For a focused search of 5–10 targeted applications, the free tier may be sufficient for several weeks.
