FingerCAD vs SessionsAI

"FingerCAD" is the first CAD application for technical drawing with fingers assisted by computer for portable devices. With "FingerCAD" you can draw houses, bridges, planimetry of apartments, mechanical components, geometrical figures, everything that can be designed with a common PC CAD. Useful for the engineers on construction site, for architects, surveyors, designers, students etc.. The design possibilities with "FingerCAD" are endless and all this using only your portable device, during a travel or comfortably seated or standing at work. The ease of use makes it very useful and versatile. The final design can be saved using standard formats (ex. DXF) and can be sent via e-mail or printed. The zoom and pan, the customization of the drawing, the common cad tools, autosaving and the ability to continue operations even in subsequent sessions of use (at boot "FingerCAD" will load automatically the design saved in the previous session of use), possibility to add measurements and free text makes it truly unique. Each CAD object is treated as a separate object; You can then go back in time by removing the objects from last to first (also in next sessions of work), select and remove the undesired parts / incorrect objects. The "automatic acquisition of nearest vertices" facilitates the drawing of adjacent graphics objects and the function "2x" allows you to draw walls (double line) automatically (you can specify the thickness of the wall as desired). The three RGB components, alpha transparency, the freehand drawing, the ability to fill an object with colors, the color palette, the color picker, in addition to the common functions of a CAD give you the ability to add manual graphical effects at the overall design (also using freehand drawing). MODIFY, COPY AND MOVE for CAD objects (also from one layer to another one). AUTOMATIC CALCULATION OF THE MEASUREMENT OF THE AREA OF A GENERIC POLYGONAL 3D SURFACE. Virtual Reality Exploration: you can walk in the 3D model and observe it using first person view (Finger3D + FingerCAD). HIGH PRECISION OF DRAWING: using the “under finger dynamic drawing preview “ you can see exactly where for example the initial / final point of a line will be placed (observing the preview window that shows the area of drawing not visible under the finger). AUTO-PAN for work area: if you reach the border of the screen, FingerCAD shifts automatically the work area so you can continue to draw longest lines - you have not to use the "zoom out" to draw long lines. .OBJ 2D and 3D export routine: export the CAD design for 3D modeling softwares such as Finger3D, Blender, Maya 3D, etc... or print it using 3D printers DXF export/import for AutoCad, qCad, SolidWorks, LibreCAD, ... PDF export. File formats conversions: - from DXF to OBJ - from DXF to PDF - from DXF to IMAGE (JPG,PNG) 3D models can be displayed directly using the "FingerCAD 3D VIEWER". DROPBOX / iCloud Drive file sharing (IN and OUT) Ability to import DXF files from a WEB LINK and/or from an EMAIL ATTACHMENT. Ability to PRINT the design (using AirPrint). Other features: - CAD (computer assisted design) - Walls with adjustable thickness - Snap to control points - Free text - UNDO/REDO for the graphics objects, from last to first - Selection and ability to transform/move/delete selected objects - Autosave - Grid - Snap to grid - Adjustable grid - Labels indicating the finger position on the cad area - Many selectable unit of measurement - Design multi-layer and multi-floor - The selected objects can be moved or copied from one layer to another layer or from a floor to another floor - Preview of other layers in the current layer - Scale and rotate - Extend - Trim - Mirror - Send with an email the generated .dxf, .obj, .pdf files - Ability to share .dxf, .obj, .pdf with other installed apps - DXF part library (architecture, communication, electrical, electronics, mechanical, misc, processing, templates, zipf_libs)

Sessions AI is a private AI workspace that runs entirely on your iPhone, iPad, or Mac. Not just a chat box: it uses real tools, works from your own documents, and creates images—all on device, with no account and no cloud. More than a chat box Most on-device AI apps just run a model. Sessions AI gives the assistant real tools and lets it do the work: calculate, convert units, look things up on Wikipedia, check your calendar, add reminders, search the web, fetch a page, generate an image. Ask for something involved and it writes a plan first—which you can read, edit, and approve before it spends a moment of compute. You see every step it takes. Ask by voice, or from a Shortcut Say "Start a chat in Sessions AI" to Siri and speak your question—it opens the app and lands the answer in a real conversation you can carry on. The Ask Sessions AI action appears in Spotlight and the Shortcuts app too, so you can build it into your own workflows. Ground answers in your own knowledge Give a persona its ownprivate knowledge base—add documents from a file or a URL, including Word, RTF, and PDF. When you ask a question, Sessions AI searches that content on device and bases its answer on it, and shows you which passages it used. Nothing is uploaded; indexing and search happen locally. Personas that keep work separate Set up a persona for each kind of work, each with its own system prompt, knowledge base, and connected tools. Switch per chat. Research stays separate from writing, and work stays separate from home. Bring your own tools (MCP) Connect Model Context Protocol servers and their tools appear right in your chat, alongside the built-in ones. Add custom HTTP headers for authentication, stored securely in the Keychain. It's your workspace—extend it however you like. Create images on device Ask the assistant to draw, sketch, or visualize—and it generates images right on your device, no cloud APIs. Choose from fast models like Stable Diffusion XL Lightning and Z-Image Turbo through to higher-quality ones like FLUX.2 Klein, with larger models such as Qwen Image on high-memory Macs. Watch a live preview as it draws, start from one of your own photos with image-to-image, and reuse the seed shown with each result to reproduce or vary it. Browse everything you've made in a built-in Gallery. Your chats are yours Every conversation is saved on your device as a plain Markdown file you can open in the Files app—no proprietary format, no lock-in, no export button needed. Pin, rename, group, and search across every chat by name or content. Your model, your choice Sessions AIruns open language models in a range of sizes—Gemma, Qwen, Ministral, Mistral, and Ternary Bonsai families among them. Pick a small, fast model for quick answers or a larger one for harder work, and set a different model per conversation. Download only what you need; remove any model to free space. Made for every screen Designed for iPhone, iPad, and Mac, with full Dark Mode support. On iPad and Mac, a roomy sidebar lets you group and pin chats and jump between your models and Gallery; on iPhone, a simple tab bar keeps everything a tap away. Built for privacy Chat transcripts, the knowledge base, and all model data stay on your device. Language models and image generation both run locally—nothing you type is sent to the cloud for AI processing. Calendar and reminder access are used only on device to answer your questions. Web search is optional; when enabled, only the search query is sent to the provider (e.g. DuckDuckGo), not your full conversation. No telemetry, no analytics, no account—just you and your device. Who it's for Sessions AI is for anyone who wants a capable AI workspace without handing their work to the cloud. Whether you care about privacy, work offline, or simply prefer to own your data, it gives you a full assistant that runs where you do: on your own device.
