Capture by RATdeck vs Sembly AI: Which Is Better in 2026?

Capture by RATdeck is a free full page screenshot and screen capture Chrome extension that takes a clean, high-resolution screenshot of an entire web page in one click, even very long scrolling pages. It automatically scrolls the page and stitches everything into a single image, so you never have to take and glue together several partial screenshots again.

As soon as the capture is done, a built-in editor opens so you can mark it up straight away. Add arrows, boxes, text labels and numbered callouts to point at exactly what matters. Use the blur and pixelate tools to hide emails, names, prices, tokens or any other private details before you share. Crop the result to the part you need, then copy it to your clipboard or save it as PNG, WebP or PDF.

There is no watermark and there are no ads. Free full-page capture needs no account and no sign-up. Privacy is a core design choice: your screenshots are processed locally on your own computer and are not uploaded to any server.

Who is it for? Capture is built for people who share screenshots for work every day: developers and QA testers writing bug reports, designers giving and receiving design feedback, marketers and agencies sending client updates, support teams writing help articles, teachers and creators making tutorials, and anyone who needs to save receipts, orders, invoices and other records from the web.

Capture runs in Google Chrome and other Chromium browsers including Microsoft Edge, Brave and Opera.

Pricing is freemium. The core full-page screenshot, annotation, blur and export tools are free. Capture Pro costs $3 per month or $12 per year and adds visible-area and selected-area capture, screenshot history and projects, before/after comparison, shareable reports, and a Guide/SOP builder that turns a series of screenshots into a step-by-step guide. Screen recording is available as an opt-in Beta.

If you are looking for a free, private alternative to GoFullPage, FireShot, Awesome Screenshot, Nimbus Screenshot or Lightshot, Capture by RATdeck gives you full-page capture plus a proper annotation editor without watermarks or forced accounts.

Capture is made by Raja at RATdeck, a bootstrapped solo founder in India building simple, private browser tools.

What problem it solves

Taking a screenshot of a long web page usually means stitching several partial captures, then opening a separate editor to annotate or blur private details, and many free tools add watermarks or upload your images. Capture does full-page capture, annotation, blur and export in one private, local extension.

Sembly AI is an agentic AI platform that turns your meetings, documents and background materials into polished, on-brand professional deliverables — proposals, pitch decks, statements of work, status reports and more — in minutes. Rather than a generic chatbot, it's built as institutional intelligence for professional-services teams, standardizing context, brand and workflow across the whole organization.

What is Sembly AI?

Sembly AI takes the raw inputs of client work — meeting notes, documents, CRM records and knowledge bases — and generates finished, branded documents from a single goal statement. You steer and edit in real time as the deliverable builds, and export native, editable PowerPoint and Word files. It centralizes client and project context so the whole team draws on the same institutional knowledge.

Who it's for

Sembly AI serves professional-services teams: consulting and advisory firms, technology-services and IT-outsourcing companies, recruitment teams and venture-capital firms. Across enterprise, SMB and freelancer segments — in management consulting, project management, marketing and product development — it's for anyone who repeatedly produces client-facing documents and wants them faster and consistent.

Key features

• Centralized client and project hierarchies
• Reusable brand packages (logos, colors, fonts, voice)
• Shared institutional context repository
• Integration of meeting notes, documents, CRM records and knowledge bases
• Deliverable generation from a single goal statement
• Real-time steering and editing as documents build
• Outputs: proposals, pitch decks, SOWs, project plans, status and QBR decks
• Native export to editable PowerPoint (.pptx) and Word (.docx)

Institutional intelligence, not a chatbot

Sembly AI's key distinction is that it standardizes knowledge and output across a team rather than depending on how well each person prompts. Context, brand rules and workflow are captured centrally, so every deliverable reflects the firm's institutional knowledge and brand — not one employee's prompting skill. For a services firm, that consistency across many people and projects is exactly what generic AI tools fail to provide.

From meeting to deliverable in minutes

The platform collapses the slow path from a client conversation to a finished document. Feed it the meeting notes and background, state a goal — "draft a proposal for this scope" — and Sembly builds the deliverable, which you refine as it goes. That turns hours of assembling decks and proposals into minutes, freeing consultants and advisors to spend time on the thinking rather than the formatting.

On-brand every time

Because reusable brand packages store logos, colors, fonts and voice, every document Sembly produces is automatically on-brand — no more manually restyling a deck to match the firm's template. Combined with native export to editable PowerPoint and Word, teams get deliverables that look professional and polished but remain fully editable in the tools clients and colleagues already use.

Control and human approval

Sembly AI keeps humans firmly in charge. You have fine-grained control over which source materials feed a deliverable, you steer the document as it builds, and there's human approval before anything reaches a client. That governance — no unsupervised output going out the door — is essential for professional-services work, where accuracy and brand compliance are non-negotiable.

Why choose Sembly AI

For professional-services teams that constantly produce client deliverables, Sembly AI is a powerful, purpose-built choice. Its centralized context and brand packages, meeting-to-document generation, native editable exports and human-in-the-loop control make it a practical way to produce proposals, decks and reports faster and more consistently — turning scattered inputs into polished, on-brand work in minutes.
