Show HN: Rediagram – put the diagrams you have on your brand

Rediagram launched as an AI diagram generator that turns a one- or two-sentence description into one of 53 diagram types rendered in a user's own brand colors, with exports to SVG, PNG, and editable PowerPoint. The tool separates the single model call that converts text into structure from a deterministic layout engine that has no node limit, so the same description produces the same diagram every time and large diagrams keep all their nodes, according to the company. A free account includes 20 credits per draw, and converting an existing diagram is free and requires no account.

Your file is read once to draw the diagram and is never stored. Converting turns on anonymous usage analytics — we never send your file, its contents or your brand URL. What we measure https://rediagram.app/privacy Paste any URL. We read its palette and type and redraw the diagram in them — about a second, no account.

Nothing is saved. Language The layout mirrors and the Arabic type scale applies, free. Translating the labels needs an account on a paid plan. Skin Type Motion Line Depth A bar in relief still measures correctly — the top face sits on the bar's end. A pie does not : squashing the circle makes the near slices read larger than the far ones at the same share.

The description above each one is the whole input. Why these come out different Most text-to-diagram tools hand the whole job to the model: it decides the content and draws the picture. That is why their output has a look, why the same description gives you a different diagram each time, and why a large one quietly loses boxes — the drawing is done against a fixed ladder, and what will not fit is dropped. Here the model does one job — turning your sentence into structure — and our own layout engine draws it. So an architecture diagram with sixty services keeps sixty services, the same description gives the same diagram every time, and what comes out looks like the rest of your documents rather than like something that was generated. - No node limit - Nothing is dropped to make a diagram fit. A subnet missing from a network diagram is not a simpler diagram, it is a wrong one. - Same input, same output - Everything after the one model call is deterministic, so a diagram going into a document under review does not change under it. - Editable when it lands - PowerPoint export carries real shapes and live text. Correct a label in the deck without coming back here. Already have the diagram? Converting one is free and needs no account → https://rediagram.app/convert Questions people actually ask - What do I type? - A sentence or two of plain description — who does what, in what order, and what talks to what. Naming the arrangement you want "one row per team", "left to right by stage" is the single thing that most changes the result, because it is the part a description usually leaves out. - Will it drop parts of a big diagram? - No. The model is only asked to turn your sentence into structure; the drawing is done by our own layout engine, which has no node limit. Generators that redraw with the model itself work against a fixed ladder and quietly drop what will not fit — on a network or a process that is not a simpler diagram, it is a wrong one. - Do I get the same diagram twice from the same description? - Yes. Everything after the one model call is deterministic, so re-running a description gives the identical drawing. That matters when the diagram is going into a document somebody reviews. - Can I change what comes back? - Click any shape to correct its type or colour, restyle the whole thing against your brand, and export to PowerPoint as real editable shapes with live text — not a picture you cannot fix a typo in. - Is it free? - Converting a diagram you already have is free and needs no account. Drawing one from a description costs us a model call per press, so it needs a free account and spends 20 credits from the monthly allowance.
