Question 1

Should I leave Celtx for RivetAI?

Accepted Answer

If you mainly need a writing suite, Celtx may still fit. If you need AI-assisted breakdown plus production scheduling and budgeting, RivetAI is the stronger prep platform - you can import .fdx from your writing tool.

Question 2

Can I write in RivetAI?

Accepted Answer

Yes. RivetAI includes a professional script editor, or you can import Final Draft (.fdx) or PDF.

Question 3

How does pricing compare?

Accepted Answer

Celtx is typically subscription-based. RivetAI Writer and Studio are one-time per project.

Question 4

Is my script used to train AI?

Accepted Answer

Never on RivetAI. Customer screenplays are not used to train RivetAI or third-party models. Our production AI was developed in-house on End Cue's own scripts - separate from customer workspaces. Tools that send your script through third-party AI providers typically process that content in those systems, so you do not get the same no-training guarantee.

Question 5

How does RivetAI handle privacy and security compared with other tools?

Accepted Answer

RivetAI is built for unreleased scripts: workspace isolation, AES-256 encryption, RBAC, MFA/passkeys, scoped share links, and a hard rule that customer scripts never train models - including third-party models. Because RivetAI's planning AI was developed in-house on End Cue data, your uploads are not handed to an outside AI vendor for training. Enterprise adds SSO and security-questionnaire support.

Question 6

Is RivetAI's AI trained in-house?

Accepted Answer

Yes. RivetAI was incubated at End Cue and developed its production planning AI in-house, trained and tuned on End Cue's own screenplays and internal production data - not customer projects. That matters for IP: you are not relying on a third-party AI stack that processes your script in another company's systems. Inference for AI features uses only the excerpts needed for the request you make.
