From first draft to call sheet
Nobody owns the handoff.
That is what this is.
ScriptLock carries a screenplay from the first line you type through locked pages, breakdown, shot division, sides, schedule, budget and call sheets — in any language, on every platform.
You own your script. We never train on it.
No card. No trial clock. The free tier is a plan.
How it works
Writing tools stop at the PDF. Production tools start at the PDF.
In between, a production runs on WhatsApp, Excel and a printout — which is where scripts leak, where two people shoot two different versions of scene 14, and where money goes missing. ScriptLock is the part in between.
Step 1
Write
In your own language, in the right format, with version history and a diff between any two drafts. Offline, on a laptop or a phone.
Step 2
Lock
Scene numbers and page numbers freeze. Revisions go out in the standard colour order with A-pages, OMITTED and asterisks, and page 42 stays page 42.
Step 3
Break down
Sixteen categories, one master element list, breakdown sheets per scene, shots with their lenses and setups, storyboards.
Step 4
Schedule
A stripboard measured in page-eighths, a Day Out of Days that shows what hold days cost, and call sheets that refuse to go out without a hospital on them.
Step 5
Shoot and deliver
Lined script, take log and DPR on set. Subtitles, dub packs, cue sheets and delivery checklists after.
For writers
Free, and not a trial
Three projects, the full editor, every language, PDF and Final Draft export — free, for good. A writer is the only route into a production, so charging a writer to type is charging at the wrong moment.
Your own language
Transliteration for Telugu, Hindi, Tamil, Kannada and Malayalam, switchable mid-line. Ten format profiles, Letter and A4.
Import what you have
Final Draft, Word and Fountain, with the confidence of the import reported rather than assumed — and a warning when a profile looks wrong.
Version history that means something
Every revision carries a hash of its text, the time and who issued it, and you can download a certificate of it. Not a copyright registration, and it says so.
Notes from people with no account
A producer on a phone comments per scene and per line without signing up — so their notes arrive in the tool instead of as a voice message nobody can act on.
For productions
The part that makes a producer stop worrying
Fourteen roles, enforced on the server. An artist gets their scenes and their lines — never the whole script, never a download, and no setting changes that.
A link per person, watermarked
Expiring, revocable, download off by default, their name on every page and an invisible mark tied to their copy. One action turns off every link at once.
You see who read it
Who opened it, which pages they reached, how far they got, how long they stayed — and a keyed hash of their address rather than the address itself.
An artist sees only their sides
Their scenes, their lines, and nothing else. The engine refuses an override that widens it, and so does a database constraint.
Budget that adds up
Globals, fringes applied per person rather than per line, cutoffs, and a topsheet that is the exact sum of its accounts. A writer never sees it; an executive sees the topsheet only.
Call sheets on WhatsApp
Where an Indian unit actually reads one, with read receipts. A published call sheet is frozen; a change is a new version with what changed at the top.
An audit log nobody can edit
Every read, share, export and permission change. Append-only by a revoked database permission, not by convention — including for us.
Languages
Write in your own
Type nenu vastunnanu, get నేను వస్తున్నాను. Transliteration for five Indian scripts, switchable mid-line. Seventeen UI languages. US Letter and A4, and ten format profiles including the Indian two-column.

Subtitle line length is counted in grapheme clusters, not bytes — నమస్కారం is four characters to a Telugu reader and eight UTF-16 units, and a 42-character limit measured the wrong way gives Telugu half its allowance.
AI
AI that reads, not AI that writes
It suggests breakdown tags, estimates a shoot day, drafts a budget from the breakdown and checks continuity. It never writes a scene or a line of dialogue, it never gives legal advice, and nothing you write trains a model — not now, not later, not “anonymised”.
Start with your next script
Three projects free, for good. If a production needs the rest, it pays while it is shooting and stops when it wraps.
