what AI can build
Build or adopt an encrypted vault, generate passwords, and sync encrypted data across devices.
A simple vault is buildable, but matching Dashlane's extension/mobile autofill, passkey support, breach monitoring, sharing, and trust posture is not a casual clone.

the prompt
Catalog estimateBuild me a personal password vault to replace Dashlane. Requirements: - A Node CLI: `vault add <name>`, `vault get <name>`, `vault list`, `vault gen`. `get` copies the secret to the clipboard with clipboardy and clears it after 20 seconds. - The vault is one encrypted file at ~/.vault/store.age, encrypted with age (shell out to the age binary), key derived from a master passphrase prompted at runtime and never written to disk. - Each entry: name, username, password, URL, notes, updated timestamp. JSON inside the encrypted file, decrypted only in memory. - `vault gen` produces a 24-char random password via crypto.randomBytes, plus a 4-word diceware option for passphrases. - `vault backup` writes a datestamped encrypted copy to ~/.vault/backups/ so I can sync it with any file-sync tool I already trust. - Fully local: no accounts, no telemetry, zero network calls. - Out of scope: browser-extension autofill, passkeys, breach alerts, sharing. Do not invent any crypto, use age exactly as shipped. - README: state plainly that KeePassXC or Bitwarden is the sane choice for most people, and that a forgotten master passphrase means the vault is gone.

questions
Can AI replace Dashlane?
Possibly for a narrower core workflow, but this catalog judgment is not a verified build. Expected gaps include: autofill polish, passkeys. Validate the prompt against your own acceptance criteria before committing.
How much does Dashlane cost?
Dashlane is listed at about $4.99/month (Premium, checked 2026-07-30), or $59.88 per year. This is a pricing reference, not evidence of a completed replacement or realized savings.
What do I lose by replacing Dashlane?
Honestly: autofill polish; passkeys; security alerts; account recovery; audited security; sharing; support. If any of those are load-bearing for you, keep paying.
Is there an open-source alternative to Dashlane?
Yes — KeePassXC (Open-source local password manager prior art; not a Dashlane clone but covers the core vau). Using prior art is also a valid exit; the prompt is for when you want it exactly your way.
