WriterDuet and CineLog get compared because both write screenplays in a browser and in native apps, both let several people edit the same script at once, both lock pages and color revisions, and both import and export Fountain and .fdx. So on the writing side they look alike, and they are alike. What I usually like to do is pick on the shape of the job instead of the feature list, because two writers finishing a draft together and a crew of 25 shooting that draft in twelve days lose things in completely different places, and these two tools are built around those two jobs. So if you got here by searching for a WriterDuet alternative, or for apps like WriterDuet, this is the long answer.
One thing before we start. Everything in here was checked on November 2, 2026. The CineLog side against the app itself, version 1.5.6. The WriterDuet side against their help center, their store listings and the prices their pricing page loads, because the page itself shows no numbers to anything that isn’t a browser. Both tools ship changes every month, so read every number as correct on that date and check again before you decide.
Short summary
CineLog is the pick when the script’s next stop is a set. When the breakdown has to become a stripboard, a shot list and a call sheet in the same project instead of a CSV export. When the crew needs the plan on phones with no signal for days, not an afternoon. When the new draft has to land on the breakdown as a diff instead of a replacement. And when the call sheet has to reach each person as their own PDF with a status next to their name.
WriterDuet is a collaborative screenwriting app, built from the start for two people writing the same page at the same time, and it’s good at it. It runs in the browser, on Mac, Windows and Linux, and on iOS and Android, it imports and exports every format a writer meets, and on the Pro plan its production tools are the real ones: locked pages with A-pages, lettered scene numbers, omitted scenes, the standard revision colors with asterisks, and a revised-pages-only PDF. Premium adds a full edit history and a two-column format. One paying writer can bring in free accounts to edit with them.
Those two paragraphs are the article. Everything below is the reason for it.
Let’s put a real production on the table
So we’re not talking in the abstract, let’s invent one. Let’s call it Harbor. It’s a scripted feature, about 90 pages, twelve shooting days, a crew of 25. Four locations, and two of them are out of town where phones drop to one bar. Six people need to change things in the plan. That’s the director, the first AD, the DP, the producer, the script supervisor and the production designer. The other nineteen need to get a call sheet every night and open it in the morning. We’ll come back to Harbor in every section, because the numbers only mean something on a real crew.
When CineLog is the pick
| Production shape | Why CineLog |
|---|---|
| A script going into production with the same crew, like Harbor | The breakdown becomes the stripboard, the shot list and the call sheet in one project. WriterDuet’s tags filter the script and export to CSV. |
| A draft that keeps changing after the lock | A scene-by-scene diff on every re-import, so the breakdown and the shot list survive. WriterDuet’s import replaces the document or makes a new one. |
| A crew on location for a week without signal | Offline for up to seven days on every device, with everything merged after. WriterDuet writes offline too, with a warning that the longer you go, the greater the risk. |
| A call sheet that has to be confirmed by morning | A personal PDF per person by email, with delivered, opened, confirmed and bounced. WriterDuet has no call sheet. |
| A client who approves the AV script | A client review link on the two-column script. WriterDuet’s ReadThrough is a comment link for any document. |

Six things I compare, in order
There are six things I compare when I look at tools like these, and those are the script and its revisions, the breakdown and the schedule, the shot list and the storyboards, the call sheet, where you can actually use the thing, and who pays. I go in that order because that’s the order a scripted production moves in. With WriterDuet, the first section is most of the comparison, so this time it’s the long one.
The script and its revisions
The first thing is the script, because on a scripted production the script is where every other document starts, and this is WriterDuet’s home ground, so let’s give it its due.
WriterDuet was built for co-writing, and that’s still the thing it does best. Two or more people type on the same page, each in their own color, with text, voice and video chat next to it, and when a partner has been away, their edits come back in red. It imports everything a writer meets, .fdx, PDF, Celtx, Fountain, Word, RTF and text, and exports all of them plus HTML and CSV. On the Pro plan the production tools are the real ones. Lock Pages sends the overflow to a page 2A, and 1AA if you lock again. Locked scene numbers give an inserted scene the letter of the one before it. Omit Scene prints OMITTED in grey and keeps the number. The production revisions run through the standard colors, the asterisk sits in the right margin, the revised pages get a colored edge, and the PDF export has a revised-pages-only option. Premium adds the full history, every change by date and writer down to the minute, and the MultiColumn tools for the two-column formats. What WriterDuet doesn’t do is compare a new draft against the old one when it comes in from outside. The import puts it in a new project, a new document, or on top of the one you have.
CineLog has a full editor too, and it imports .fdx, Fountain, PDF, RTF and plain text. The part I lean on is what happens on the second import, because a scripted production gets new pages every week. CineLog shows the new draft as a diff against what you already have, scene by scene, and you accept what changed. It doesn’t wipe your breakdown and your shot list to make room for the new file. And once the script is locked, it does the same production things. A new scene between 12 and 13 becomes 12A, a new page after 16 becomes 16A, and a cut scene prints as OMITTED and keeps its number for good. Every revision round gets its color, the changed lines get their asterisks in the margin, and you can export only the revised pages on that color, because that’s what goes out to the crew on a Tuesday night. What CineLog doesn’t have is the per-writer edit history, the chat, the Celtx and Word import, or the alternate-line and read-aloud tools.
So for Harbor, where the script gets locked about two weeks before day one and then revised every few days, both hand the AD the pink pages with the page numbers true. If the pages were written by two people at once, WriterDuet got them there more comfortably. The difference is what the pink pages are attached to.
The breakdown and the schedule
Now that the script is in, the next thing is the breakdown and the schedule, and this is where WriterDuet stops.
WriterDuet’s Tagger, on every plan including Free, tags a line or a selected word with a color, nests child tags under it, and filters the script by tag, so you can see every prop in the script in one view. The locations and scenes report prints the locations, the characters, the pages and the eighths as a PDF, and the statistics come out as CSV. That’s a breakdown you read. It doesn’t go anywhere. There’s no stripboard, no schedule, and no export to a scheduling program. Their help center has no article for any of it, and the word “stripboard” doesn’t appear in it.
CineLog does the breakdown by selecting text in the script and picking one of twelve categories, and it marks the page with the underline, the circle, the asterisk and the box that people know from paper breakdowns. The thing I like most is what happens with cast. CineLog tags every character on every line they speak, gives each one a numbered talent slot, and that number sits on the strip, in the shot list’s cast column and in the cast grid on the call sheet. You tag once. It shows up everywhere. The stripboard has day breaks, a boneyard for the scenes you haven’t placed yet, the standard strip colors, and it lets you split a scene across two days. A finished day flows straight into that day’s call sheet, and the board exports as a PDF. What CineLog doesn’t print yet is the day out of days report.
For Harbor, twelve days and 25 people, this is where the writing app hands off to something else, and CineLog is that something else without the handoff.
Shot lists and storyboards
Now that the days are laid out, the next thing is the shot list, and this one is short.
WriterDuet has a list-of-shots report, which filters the script down to its shot lines and their sluglines, and you can insert a reference image on a line. There’s no shot list as a document and no storyboard. Their help center search for storyboard returns the mind map.
CineLog runs two shot lists off the same shots, a linear one in script order and one per production day, with seventeen default columns, your own columns on top, and your own dropdown values for shot type, angle, lens and movement. You can populate the first pass of the list from the script and then reorder by drag, whole scenes at a time. The Cast & Crew column shows the cast by the same numbers the schedule uses, so one look tells you who’s in the shot. Each shot holds several storyboard frames, and the shot list PDF prints the frames next to the rows. What CineLog doesn’t have is a drawing tool. You bring the frames in as images, from a sketch, a photo or a previs render.
For Harbor, the DP wants the shot list on an iPad at the location scout, and the scout has no signal. That’s CineLog.
Call sheets
The next thing is the call sheet, and this is the document the whole crew judges the tool by, because it’s the only part nineteen of our 25 people will ever see.
WriterDuet doesn’t make call sheets, and it doesn’t claim to. What it has nearby is sides: export specific scenes or pages, filter by character, watermark them, and send them to an actor with a ReadThrough link.
CineLog’s call sheet pulls the day from the stripboard and the shot list, so the schedule block is a live copy of the day and not a re-typed one, and the cast grid carries the numbers the breakdown gave the cast. It fills the weather and the sunrise and sunset from the location and the date, it carries the nearest hospital and the parking you saved on each location, and it autocompletes the addresses. It sends a personal PDF to each person by email, and for every person you see delivered, opened, confirmed or bounced. And the night before day five, the sheet for day five starts from what day four already knew.
For Harbor, that’s nineteen people who need a sheet every night, from the same project the script lives in. What CineLog doesn’t cut yet is sides.
Where you can actually use it
Now that we’ve gone through the documents, the next thing is where you can open them, and here WriterDuet covers more ground than most writing apps.
WriterDuet runs in the browser, with Chrome recommended, in a desktop app for Mac, Windows and Linux on the paid plans, and in iOS and Android apps. You can write offline in the browser and the desktop app and it syncs when you’re back, with their own warning that the longer you go without syncing, the greater the risk, and that logging out clears the local changes. Real-time collaboration starts on Plus, and a paid writer can invite free accounts that edit alongside them.
CineLog is a native app on macOS, Windows, iOS and Android, and it also runs in a browser at app.cinelog.com. Every device keeps a local copy of the project, so the shot list, the script and the call sheets open with no signal at all. You can work offline for up to seven days after you’ve signed in, and when the connection comes back, your changes and everyone else’s merge in the background. The people you invite get view or edit rights per tool, so the script supervisor can edit the script and only read the schedule.
For me, for example, this is the one that decides it, because I’ve never been on a location where the signal was good in every room. On Harbor, two of the four locations are out of town for three days each. WriterDuet writes offline there, with a warning. CineLog runs the whole production there, the script, the board, the shot list and the sheets, for a week, and merges it all when the van gets back to town.
Pricing, and who pays for the crew
And the last thing is the money, and the key here isn’t the first number on the pricing page. It’s what the number buys once the script leaves the writer’s desk.
WriterDuet’s Free plan has three projects with one document each, and read-only collaborators. Plus is $9.99 a month, or $7.49 billed yearly, with unlimited projects and real-time collaboration. Pro is $11.99, or $8.99 yearly, and that’s the one with the production tools, locked pages, Omit Scene and the revision tracking. Premium is $13.99, or $10.49 yearly, with the full history, MultiColumn, read-aloud and translation. There’s a 14-day trial, students and educators get half off, and only one co-writer needs a paid plan, because free accounts can edit a project a paid writer shares with them, short of creating revisions. For two writers on a draft, that’s one of the better deals in the business, and I’m not going to pretend otherwise.
CineLog has a free plan with one project, every tool, offline mode, and two collaborators. Filmmaker is $15 a month with three projects and twenty collaborators. Production Company is $40 with ten projects and fifty collaborators. Studio is $90 with thirty projects and a hundred collaborators. There are no seats. The people you invite make a free account and get view or edit rights on the project, based on what you give them, and one subscription unlocks the app on every platform.
So let’s put Harbor on it. Six editors, nineteen readers, one project.
| Tool | Plan for Harbor | Per month |
|---|---|---|
| WriterDuet | Pro for the owner, free accounts for the other five editors | $11.99, for the script, plus a scheduler and a call sheet tool |
| CineLog | Production Company, all 25 on the project | $40, for the script and everything after it |
That’s not a comparison of two prices. It’s a comparison of two jobs. WriterDuet is the cheaper way to write a script with a partner, and CineLog is the only one of the two that takes the script to the set.
What neither of them does
A quick word on what both leave out, because it’s the reason every production I’ve been on still had a spreadsheet open.
The budget. Neither has one.
Drawing. Neither has a pencil. CineLog holds several image frames per shot, and WriterDuet holds an image on a script line.
Post. Both stop before the edit. Review, approval and delivery are a separate tool and a separate bill.
A quick exercise before you pick
So here’s a quick exercise before you move on to a trial.
First, figure out whether this script is going to be shot by a crew in the next six months. If it’s a spec written with a partner, WriterDuet is a very good place to write it. If it has a shoot date, read on.
Second, tag three scenes in each tool and then try to put them on a shooting day. On CineLog the tags become strips. On WriterDuet the tags become a filter and a CSV.
Third, check the signal at each location before you sign up for anything. Both write offline. Ask which one you’d trust with the whole production for a week with no sync.
The bottom line
WriterDuet is the best way to write a script with a partner in real time, with real production revision tools on Pro and a price that lets the partner in for free. CineLog is the pick once the script has a crew, because the breakdown becomes the board, the shot list and the call sheet in the same project, the whole crew is on it for one price, and the project runs on every device with or without a signal. That’s WriterDuet vs CineLog.
Questions people ask
Is CineLog an alternative to WriterDuet?
For writing a script that’s going into production with your own crew, yes. CineLog imports Fountain and .fdx, co-writes in real time, locks scene numbers and pages, colors revisions and exports the revised pages, and adds the breakdown, the stripboard, the shot list and the call sheet in the same project. For two writers on a spec, WriterDuet’s co-writing and chat are its own thing.
Which one is cheaper?
For writing, WriterDuet, at $11.99 a month on Pro with free accounts for the co-writers. For a production with a crew on it, CineLog, because $40 a month covers 25 people and every tool, and WriterDuet covers the script.
Does WriterDuet lock pages?
Yes, on Pro. Overflow goes to a page 2A, scene numbers lock with letters, Omit Scene prints OMITTED, and the PDF can be revised pages only. CineLog does the same on every plan.
Which one works offline on set?
Both write offline. WriterDuet syncs when you’re back and warns that a long gap raises the risk. CineLog works offline for every tool on every device for up to seven days and merges everyone’s changes after.
Does WriterDuet do a script breakdown?
It tags words and lines, filters by tag, and prints a locations and scenes report and CSV statistics. It has no stripboard, shot list or call sheet. CineLog’s breakdown becomes the stripboard and the call sheet in the same project.
Can I bring my WriterDuet script into CineLog?
Yes. Export it as Fountain or .fdx and import it. Re-imports show as a scene-by-scene diff.
Do my collaborators need to pay?
On CineLog, no, and they get view or edit rights per tool. On WriterDuet, one co-writer needs a paid plan and the free accounts they invite can edit, short of creating revisions.
Which one has a two-column AV script?
Both. WriterDuet has A/V templates, with the MultiColumn tools on Premium. CineLog’s AV script has a client review link where the client comments and approves without an account.
Which one runs on Android?
Both. WriterDuet has an Android app for writing. CineLog’s Android app holds the whole project, the script, the board, the shot list and the sheets.
Can I switch from WriterDuet to CineLog?
Yes. Export the script from WriterDuet as .fdx or Fountain and import it. The breakdown is tagged on the page with the cast done for you, later drafts show as a scene-by-scene diff, and CineLog exports .fdx and Fountain if the file needs to go back to a co-writer.
To recap
To recap, in this article we talked about picking on the shape of the job instead of feature count, we walked six things in order, the script and its revisions, the breakdown and the schedule, the shot list and the storyboards, the call sheet, where you can use it, and who pays, and we put a twelve-day, 25-person feature on both. WriterDuet is the co-writer’s editor with real revision tools. CineLog takes the same script to the set, with the whole crew on it, on any device, for one price.
If you want to see the CineLog chain for yourself, the Free plan is one project with every tool, and you make the account inside the app after you download it. So put your own Harbor on it, and then move on to the part that matters, which is the shoot.
