Improved validation for attachment uploads is Lovable's Agent feature: Files you attach in chat are now validated against your plan's file size limit up front.
Files you attach in chat are now validated against your plan's file size limit up front. A file that is too large is rejected the moment you attach it, with a message stating the maximum size. Limits are applied consistently across all plans, and Enterprise plans can now attach files up to 1 GB.
Example workflows
Starting points built from this record, not transcripts of a run. Each prompt is written the way it should be sent, as one paragraph, and each is worth editing before you send it.

Decide whether it fits your project
