For architecture practices

The shared board for architects.

Place your drawings and images, calibrate them to real-world scale, sketch in perspective on tracing sheets, dimension and annotate—together, live. And soon, generate images from them with the best AI engines.

What tabello does

All the work around a drawing, together and remotely.

01Place

Your drawings and images, placed on the board.

Drag in PDFs, site photos, references, sketches, renders. A PDF arrives at its true paper size; an image keeps its type—photo, perspective, sketch—and tabello never lends it a scale it doesn’t have.

  • PDFs, images, photos, references, orthophotos
  • Crop, rotate, flip, align
  • Boards with several hundred items stay smooth

Import

02Calibrate

Scale calibrated in two clicks.

Click both ends of a length you know and type its value: the drawing is calibrated. Every dimension updates, and a calibrated scale is never confused with an assumed one.

  • Each drawing carries its own scale
  • An unverified dimension says so (≈)
  • Photos and perspectives: indicative dimensions, no false numbers

Calibration

03Sketch

Tracing sheets, just like on the drawing board.

Lay a tracing over a drawing and draw through it, freehand, with a straight edge, in perspective. Lift it to see underneath, pin it to the drawing it traces: it follows it everywhere.

  • Smoothed linework, with a stylus or a mouse
  • Two-point perspective grid
  • A tracing remembers where you drew on it

Tracing

04Construct

Perspective and axonometric drawing, built in.

Set up a two-point perspective grid, or an axonometric grid, and draw: the pencil follows the receding lines by itself. The grid stays a guide—you see it when you look for it, and forget it as you draw.

  • Two vanishing points, true verticals, adjustable horizon line
  • Isometric axonometry
  • Every line keeps its grid: pick up a sketch weeks later

Perspective

05RenderSOON

Images, with today’s best engines.

Connect a view, materials, a mood and a few words on a render sheet: tabello turns them into an image with the best image-generation engines available, respecting the geometry of your view.

  • Only what you connect is sent to the engine, when you click “Generate”
  • Off by default: the team decides to turn it on
  • The cost in credits is shown before you start

AI rendering

06Comment

Comments followed through to the end.

Place a comment on the exact spot on the drawing. It receives a number that will never change; people reply to it, it gets assigned, and only the person who raised it can mark it resolved.

  • Open, in progress, resolved: one shape per status
  • It follows the drawing when it moves or is cropped
  • Comments report for the minutes

Comments

07Together

Together, live, without overwriting each other.

Everyone sees the others’ cursors and lines as they happen. Undo only reverses your own actions: never a colleague’s work.

  • Every item keeps its author and date
  • A board reopens where you left it

Real time

08Organise

Layers to show what matters.

Organise linework and annotations into layers—structure, services, furniture, client. Hide them for yourself only, or for everyone when that is the intention.

  • Create, rename, sort in a single move
  • What is hidden can’t be erased by mistake

Layers

09Share

Invite a client without opening up your practice.

A link is enough to open a board, and only that one. You choose what people can do there: view, comment, draw or manage everything. Guests don’t take a seat.

  • Viewer, commenter, editor, manager
  • Teams, projects, bin: nothing is deleted in a single click

Sharing

10Anywhere

At the office, on site, on a tablet.

tabello opens in the browser, with nothing to install. On a tablet, the stylus draws, the finger arranges: the palm never leaves a mark.

  • Computer, iPad, Android tablet
  • No action reserved for the keyboard
  • Hosted in Europe, encrypted in transit

Tablet

What you can count on

An architect’s tool, not a whiteboard.

Metric, exclusively

Metres, centimetres, millimetres. An unverified measurement says so, and a photo never invents a scale for itself.

Your drawings remain yours

Data hosted in the European Union, backed up every night. Nothing is resold, nothing trains a model.

Organised by project

The team owns the projects, each project its boards. The bin is the only place where anything is deleted.

Paid per seat, not per guest

You pay for the people who draw. Clients, consultants and contractors come in as guests.

Launch offers

Place your first drawing today.

The free plan is enough to try it on a real project. Paid plans are offered at launch prices.
