How Langdock builds your files
A bit of context on what happens behind the scenes goes a long way toward getting great results. Generating a slide deck or a Word document is a different kind of task than answering a chat question: it’s a visual output, and Langdock produces it by writing the underlying file code (for example, XML for PowerPoint), rendering it, reviewing the rendered result, and refining it in a loop. Think of it like a designer sketching a slide, stepping back to check it, and polishing — just much faster. Three principles make this process shine:- Iteration is the superpower. Langdock builds, renders, and improves in passes. You can join that loop at any point: a short nudge like “use the two-column layout here” is usually all it takes to lock in the final version.
- Focus beats volume. A handful of slides built with care produce dramatically better results than asking for a full deck in one go. Break long decks into sections and give each one the attention it deserves.
- Your template is the north star. The clearer your template — clean master slides, meaningful layouts, a good description — the more closely Langdock can match your style. Investing a few minutes in the template pays off every time it’s used.
The six-step framework
The best workflow breaks into three phases and six steps. This is the same sequence we use internally to generate the webinar decks shown in our own presentations.Phase 1: Build
- Start from the template. Open a new chat from your template — either click Use Template in the Library, or use the Create document / Create presentation button in a new chat and pick a template there. This gives Langdock the structure and styling to work with from the start.
- Add context and generate. In the same chat, provide the content the file should contain. Reference your Folders, upload documents, or use Web Search and Deep Research to gather what’s needed. You can even ask Langdock to research best practices first (“how should a product launch deck be structured?”). Then ask for the first draft.
Phase 2: Refine
- Iterate slide by slide. Do not try to fix everything in one prompt. Go through individual slides and point out issues: “this slide has too much text, move the detail to speaker notes”, “use the comparison layout with two columns”, “the chart title is cut off”.
- Add visuals intentionally. Visuals rarely appear on the first try. Ask for specific charts, diagrams, or timelines slide by slide. A useful trick: ask the image generation tool to mock up a slide layout as an image, then feed that image back and ask for the PowerPoint version of it.
Phase 3: Polish
- Do a full-deck review. Once individual slides are right, ask for a consistency pass across titles, fonts, and layouts. The model will catch alignment and branding issues it missed during per-slide edits.
- Download and sanity-check. Open the file outside Langdock. If something still looks wrong, tell Langdock exactly what’s broken. Errors opening the file are almost always recoverable with one more pass.
What works well vs. what needs iteration
Word documents are Langdock’s strongest format today — filling structured templates, inserting content, and matching formatting all work very well with minimal iteration. Presentations have more visual variables, so some slide types come out great out of the box while others benefit from a quick iteration pass. For presentations specifically:| Works well out of the box | Needs iteration |
|---|---|
| Matching your team’s template, brand, and master layouts | Complex data charts and tables |
| Structured comparisons (two columns, before/after) | Image placement and custom illustrations |
| Title slides, chapter dividers, section separators | Timelines, process diagrams, and flowcharts |
| Short decks (up to ~10 slides) | Long decks in a single generation |
| Filling placeholder text in existing layouts | Highly custom template masters with many layouts |
For long decks, generate them in chunks. Build the first 5 slides, lock them in, then continue — this keeps each pass focused on quality rather than volume.
Worked example: an invoice template
This is the same workflow used in the webinar demo. It shows the full loop from first upload to a reliable, reusable template.Upload the template
Upload your existing invoice
.docx to the Library. Langdock analyzes the file and drafts a description of its structure (header, line items table, totals, payment details). You can edit this description before saving.Try it with a real input
In a new chat, click Create document, pick the invoice template, and paste in the source data (for example, a customer email requesting an invoice). Langdock reads the email, fills the structured fields from unstructured content, and generates a new
.docx.Spot what's missing
On the first try, some fields may still contain placeholders. Open the file, note what’s wrong (“subtotal and total weren’t calculated”), and tell Langdock directly.
Update the template instructions
Open the template in the Library and sharpen its instructions to cover what was missed (for example: “always calculate Subtotal and Total from the line items before filling them in”). Save the change — the next generation picks up the updated instructions automatically.
Iterating on a template
Templates aren’t set in stone. If the same mistake keeps happening (for example, “field X is always empty”), open the template in the Library and sharpen its instructions directly. Future generations pick up the updated instructions automatically.Templates require Skills to be enabled in your workspace. See Admin: enabling templates.
Things to know
- Results vary by document complexity. Simple layouts and text-filled documents usually come out great on the first try. Custom charts, detailed illustrations, and very intricate template masters may need a pass or two of specific feedback.
- Runs aren’t perfectly deterministic. Two generations from the same template and prompt can differ slightly. Test a template on realistic inputs before rolling it out workspace-wide.
- Template edits currently happen in the Library, not in chat. You can download, edit locally, and re-upload, or update the instructions directly in the Library. Chat-based changes apply to the generated output, not to the template source — editing templates from chat is on the roadmap.
Sharing across your workspace
Once a template reliably produces good output, share it. Two permissions control what users can do:- Share with users and groups: any user can share by default.
- Promote to workspace: admin-only by default.
