Questions people ask most
Do I need an account?
No. Core browser tools work immediately. An account is only for optional synced preferences and favorites.
Are my files uploaded?
Local-labelled tools process data inside your browser. Cloud and hybrid tools explain the transfer before it begins.
Can I request a new tool?
Yes. Describe the input, transformation, and result you need without including passwords, private files, or other sensitive data.
Can I use Toolars from my browser toolbar?
Not yet. The Chrome and Firefox surfaces are in build; the extension page shows the current release status.
Focused tools. Better outcomes.
