SourcePilot is a desktop text editor with built-in AI writing assistance. The company positions it as a personal writing tool you own, with a clean, minimal interface meant to keep attention on the page. The basic editor works without an account or login, while the AI features sit on top and are limited unless you subscribe.
The product is aimed at people who write regularly: bloggers, business professionals and authors. Its distinguishing idea is that the AI works from sources you attach to a document, such as articles, videos and web pages, rather than only from the text on screen. SourcePilot's pages also state that users own all copyright to what they write.
The workflow has three steps on the company's site. You open SourcePilot and start writing a blog post, article or email. When you want help, the AI offers suggestions, improvements and ideas. A third step, publishing, is labeled Coming Soon, so today the product centers on drafting and refining text rather than on getting it out the door.
Context is what shapes the AI output. You can add YouTube videos, articles and web pages to a document as sources, and the assistant uses them along with the surrounding text when it responds. The homepage says AI features require downloading a local model, while the pricing FAQ says AI features need an internet connection. The sources are not fully consistent on this point.
Several AI actions are built around selected text and sources. Select to Enhance lets you highlight a passage and ask the AI to improve it using the selection and your attached sources. Complete with AI uses a slash command to continue your text. Add Citations inserts references to your sources into the text and the document, and lets you ask for an edit tied to a specific citation.
Beyond those, the site lists a general writing assistant for grammar, spelling, style, tone, clarity and readability. Local document management lets you create directories and manage multiple documents, stored on your device. The site also lists a Branching Text feature, though its description repeats the Select to Enhance copy, so its exact behavior is unclear. An AI Slop Detector appears in the navigation.
SourcePilot is a desktop AI text editor with a minimal interface. It helps writers draft and refine text using AI that can draw on sources attached to a document, such as articles, videos and web pages.
Individual plans are Starter at $19 per month, Pro at $49 per month and Ultra at $149 per month. Teams is listed at $99 per user and Enterprise is custom, but both are marked Coming Soon.
The basic editor can be used without an account or login, and the site says AI features are limited without a subscription. The pricing page also has a Download Free button on the Starter plan and a 30-day money-back guarantee.
The site states that users own all copyright to their content, whether it was created with or without AI assistance. SourcePilot says it never claims ownership or intellectual property rights over user writing.
The pricing FAQ says SourcePilot supports models including GPT-4, Claude and Gemini, and can switch between models based on performance. It also mentions custom models that users can train on their own data.
The pricing FAQ says basic editing works offline and documents stay accessible locally, but AI features require an internet connection. The homepage separately says AI features require downloading a local model, so confirm the current behavior before relying on it.
The pricing FAQ lists Windows, macOS (Intel and Apple Silicon) and Linux. The homepage download buttons show Windows and macOS builds labeled beta.
The site targets content creators, business professionals and authors. It suits individual writers who want AI help grounded in their own sources, while team features are not yet available.
