## Scribbr

Scribbr was built around a simple promise: help students submit work they feel confident about. The core of the service is human proofreading and editing, delivered by a hand-picked pool of academic editors who go through an in-house training programme before they are allowed to take orders. Documents are returned with tracked changes, in-text comments and a short personal letter explaining the reasoning behind the main edits.

Alongside the human service, Scribbr offers a growing library of AI writing tools. The Academic Check bundles together grammar and language review, citation checking, plagiarism scanning and AI-content detection into a single upload, which is convenient when you want one pass over an entire paper rather than juggling separate tools. Individual utilities such as the citation generator for APA, MLA, Chicago, AMA, IEEE and ACS, the paraphrasing tool and the text summarizer can be used on their own without paying for an edit.

The platform also maintains a large free knowledge base of academic writing guides that has become one of the more popular ways students discover the brand. Pricing depends heavily on document length, chosen turnaround time and add-on checks, so the practical way to get a number is to upload a file and select services in the order flow.

**Pricing & Plans:** Freemium model. Free tools include the citation generator, grammar checker and summarizer. Human proofreading and editing, the plagiarism checker, AI detector, AI proofreader and Academic Check are paid per document, with the final price depending on page count, delivery speed and any add-on checks such as structure or clarity review.

- **Human proofreading and editing:** A vetted academic editor reviews your paper within hours and returns tracked changes, comments and an explanation letter.
- **Plagiarism checker:** Scans your document against a large web and publication database to surface potentially unoriginal passages before submission.
- **AI detector and AI humanizer:** Flags text likely generated by large language models and offers a rewriting mode aimed at making AI-assisted drafts sound more natural.
- **Citation generator:** Creates and verifies references in APA, MLA, Chicago, AMA, IEEE and ACS styles from a URL, DOI or title search.
- **Academic Check bundle:** Runs grammar, citations, clarity, plagiarism and AI-detection checks in a single upload of the whole document.

**Strengths:** Combines human editors with AI tools rather than relying on one alone; Strong editorial vetting process and a large pool of academic specialists; Free citation generator and knowledge base are genuinely useful on their own; Transparent turnaround options starting from a few hours

**Limitations:** Paid services are priced per document, which adds up for long theses; AI detector verdicts can still be disputed by institutions; Some premium checks require you to buy them alongside an editing order

## Thinking Line

Thinking Line is a browser-based creative studio for turning written ideas into visual stories. You enter a topic, pick a style, voice and number of scenes, and the platform generates a hand-drawn whiteboard explainer video with narration. Alongside video, it produces editable SVG graphics so teachers and designers can restyle or extend the artwork. Recent engine updates focus on smoother pen strokes and cleaner labels for a more natural doodle look.

The platform is built around practical use cases: classroom lessons on science, mathematics and biology; corporate training such as warehouse safety and cybersecurity awareness; and creative storytelling. A published showcase library lets you explore generated lessons for inspiration, and a voice library lets you assign different narration voices per request. Native animated scenes — bar charts, pie charts, graphs and cycles — can draw themselves inside lessons.

For developers and teams, Thinking Line exposes an API including a WebSocket generation endpoint, so video production can be embedded into other products or automated pipelines. Pricing starts with a free tier for experimentation and scales through a Pro plan to Enterprise agreements with custom branding, SSO and dedicated support.

**Pricing & Plans:** Free tier available ($0): 4 videos/month, standard voices, 720p export, watermarked. Pro is $29/month: 30 videos/month, premium AI voices including cloning, 4K export, no watermark, commercial usage rights. Enterprise pricing is custom and adds API access, dedicated support, custom branding, SSO and security.

- **Prompt-to-video generation:** Describe a topic and receive a multi-scene, narrated, hand-drawn explainer video rendered in a doodle style.
- **Editable SVG output:** Generate vector graphics you can open in design tools and restyle or extend for your own materials.
- **Native animated scenes:** Built-in bar charts, pie charts, graphs and cycle diagrams that draw themselves within your lesson.
- **Voice library and cloning:** Choose from multiple narration voices, with premium voice cloning available on the Pro plan.
- **Developer API:** Integrate video generation via REST and WebSocket endpoints for automated or embedded workflows.

**Strengths:** Free tier lets you test the full prompt-to-video flow before paying; Editable SVG output is useful beyond videos; Native chart and diagram animations suit teaching content; API and WebSocket access enable automation and integration

**Limitations:** Free plan caps output at 4 videos per month with watermarks; Voice cloning and 4K export require the paid Pro subscription; Enterprise features such as SSO require contacting sales
