Know where document processing happens
Trial, Starter, Business and Scale are SaaS plans. Required content may be sent to the configured AI API provider, currently OpenAI API, only to perform the user-requested analysis.
Private/self-hosted AI is an Enterprise option under a separate agreement; that mode can use a dedicated model instead of a third-party GenAI API. NexaFile does not claim that SaaS data never leaves the customer company.
From documents to business decisions
A clear workflow: add documents to NexaFile, extract information with AI, validate rules, complete human review, and export reports.

Case Studies →Scale: buy more AI Credits and paid renewal
Scale supports up to 100 members. During a paid period, when AI Credits are running low the workspace is warned; when there are not enough AI Credits for a task, Owner/Admin can buy more AI Credits to continue. Buying more does not increase the member limit, reset storage or move the original period end.
At the period end, the next 30-day plan period must be paid to continue new AI processing. Until payment is confirmed, new AI processing pauses while existing data and results remain available.
