just build things.

A collection of focused AI tools

just build things. brings media analysis, content generation and AI chat into one website. Instead of beginning every task in a general conversation, you can open a tool for a particular input or output: a PDF summary, an image prompt, a spoken recording or a small web project.

It suits independent creators, students and people who regularly switch between writing and visual tasks. The site also contains ordinary utilities, including formatters and converters. Those utilities are separate from its AI features; a large tool count should not be read as the number of distinct AI models.

Document analysis and visual generation

The PDF analysis tools accept documents for summaries, questions and extraction. Specialized options frame a task around the type of material, such as a research paper, invoice or technical manual. This can make the initial request more specific than asking for an unrestricted summary.

The image generator works from a text prompt, with model, style and image-shape choices. Separate presets organize common visual uses. Describe the subject and intended composition before selecting a preset; a descriptive style label does not establish that the resulting image will contain every requested detail.

The wider collection includes audio and video analysis, speech conversion, writing templates, quizzes and flashcards. These are different tools with different inputs. Choose the relevant tool before uploading a file rather than assuming every screen understands every media format.

Vibe Coder for small browser projects

Vibe Coder creates editable HTML, CSS and JavaScript, with a live preview and copy or download options. Its FAQ describes single-file web projects such as games and interactive utilities. A prompt can specify controls, scoring, layout and the behavior of individual buttons.

That makes a simple demonstration or learning exercise a clearer starting point than an application requiring accounts, persistent records and payments. The presence of generated code is not evidence that a complete production backend has been configured. Inspect the output and test the interactions before using it elsewhere.

Example: prepare an educational explainer

A tutor could upload a short, permitted reference PDF and request its main concepts and definitions. They would compare the result with the source, correct any omitted qualifications and use the reviewed notes to draft a lesson. An image tool could then produce an illustrative scene, while Vibe Coder could create a small interactive example.

Review each output separately. Check the image against the explanation, try the interactive controls and make sure the lesson distinguishes a simplified demonstration from the full subject. This is a suggested workflow, not a report of hands-on testing or a promise that outputs will connect automatically.

Free tools, paid models and practical limits

The homepage distinguishes free access from Premium and Premium+, with more model and generation choices on paid access. Video and music generation appear in the higher tier. Confirm the current billing interval and feature selection before subscribing; a yearly-billed monthly equivalent is different from a month-to-month price.

The PDF FAQ notes that scanned text depends on legibility and that long-document summaries can lose detail. Its image guidance also acknowledges difficulties with precise counts and lettering. Keep source documents and editable originals, check important passages, and treat generated media as material to review rather than a finished factual record.
