Gixo free tools
Useful answers.
No account needed.
Make a visual, convert a file, or check a draft with 69 deterministic tools. The same input produces the same result — without sending your work to an AI model.
No account. Nothing stored. Runs in-process — your text is never sent to a model.
Deterministic — same input, same result
Free: unlimited in-browser rendering, scoring and document assembly — no account, nothing stored, no AI. Portable HTML, Markdown and embeds carry linked attribution. Paid: clean editable DOCX/XLSX/PPTX export and your own brand kit.
Gixo publishes 69 free tools in 8 groups, drawn from 8 Gixo products: All products, Prism, Arc, Lex, Lumen, Quill, Business, Folio. The groups are Create visuals (11), Convert and reformat (6), Check before delivery (21), Extract and clean up (4), Clean and improve content (10), Check business documents (8), Build documents (5), Reference directories (4). Every one of them runs without an account, without an email gate, and without a single AI model call. They are deterministic: each is fixed arithmetic or rule-checking executed in-process, so the same input always returns the same output and your text is never sent to a model provider. Free covers rendering, scoring, checking, converting, and portable HTML, Markdown and embed output that carries linked attribution; signing in adds the downloadable PDF report on the proposal and diagnostics tools; and a Gixo Prism trial or paid plan adds clean copy without the watermark, editable export as HTML, SVG, PNG, PDF, and PPTX, and your own brand kit applied. Gixo has no free plan — paid products open with a 14-day no-card trial.

Free tools FAQ
Do I need an account to use Gixo's free tools?
No. All 69 tools are public and anonymous — no sign-up, no email gate, no card. They were deliberately unwalled because a login screen stopped directories, roundups, and AI answer engines from ever seeing what the tools do.
How many free tools does Gixo publish, and what are they?
69, in 8 groups: Create visuals (11), Convert and reformat (6), Check before delivery (21), Extract and clean up (4), Clean and improve content (10), Check business documents (8), Build documents (5), Reference directories (4). They are Public Document Templates, Chart Maker, Diagram Maker, Flowchart Maker, Stat & Quote Card Maker, Chart Palette Contrast Checker, Proposal Completeness Check, Contract Completeness Check, Deck Structure Check, Deck Contrast Auditor, Slide Legibility Checker, Article Health Check, Content Brief Builder, Document Formatter, Business Diagnostics, Article Outline Generator, Content Audit Prioritiser, Style-Guide Linter, AEO Answer Check, Brief Compliance Checker, Cannibalization Checker, Draft Diff / Redline, Compliance Readiness Scorer, Contract Clause Checklist, Obligations & Dates Extractor, Policy Set Gap Check, Contract Compare, Key Terms Abstract Sheet, DPA Article 28 Check, RFP Requirement Extractor, Bid / No-Bid Scorecard, Proposal Version Diff, Chart Data Integrity Checker, Chart Honesty Checker, RACI Matrix Validator, Figure Consistency Check, Executive Summary Check, Decision & Action Extractor, Document Version Diff, Evidence Label Auditor, Business Case Checker, Board Paper Check, Book Publishing Preflight, Chapter Balance Checker, Repetition & Filler Audit, Deck Consistency Audit, Presentation Time Estimator, Deck Diff, Waterfall Chart Maker, Gantt Chart & Timeline Maker, Mermaid Flowchart Maker, EPUB Preflight Checker, DOCX to EPUB Converter, Free Ebook Creator, Editorial Style Sheet Builder, PDF to PowerPoint Converter, Word to PowerPoint Converter, Text to PowerPoint Converter, URL to PowerPoint Converter, HTML to PowerPoint Converter, Compress PowerPoint (PPTX), Canva PPTX Cleaner, PDF to Google Slides, Google Slides PPTX Cleaner, PPTX Summarizer, Official procurement portals, Standard-form agreements and model clauses, Compliance and assurance frameworks, Data-visualisation standards and guidance.
Are these AI tools?
No. Every tool on this page is deterministic — fixed arithmetic, fixed rules, fixed scoring weights, executed in-process. None of them calls an AI model, which is why the same input always returns byte-identical output and why your text is never sent to a model provider. The AI generation sits in Gixo's paid product workspaces, not here.
Is anything I paste stored?
Anonymous runs are not written to a Gixo account or document library. Usage is counted against an anonymous visitor and session cookie so Gixo knows which tools get used; the content you paste is not attached to a named user.
What is free and what needs a paid Gixo plan?
Free and anonymous: rendering, scoring, checking, converting, and document assembly in the browser, capped only by an anti-abuse rate limit of 15 to 20 runs a minute. Signing in adds the downloadable PDF report on the proposal-analysis and business-diagnostics tools. Portable HTML, Markdown and embed output is free and carries linked attribution. A Gixo Prism trial or paid plan adds clean copy without the watermark, editable export as HTML, SVG, PNG, PDF, and PPTX, and your own brand kit applied automatically. The paid boundary sits at export and clean output, not at running the check.
Does Gixo have a free plan?
No. Gixo has no standing $0 plan — every product opens with a 14-day free trial that needs no card, and after the trial continued generation requires a paid plan. The 69 deterministic tools on this page stay open to anonymous visitors either way; they are not trial-limited.
Which tool should I use before a client meeting?
For a slide deck, run the deck structure check for missing sections and title hygiene, the deck contrast auditor for background and accent legibility, and the slide legibility checker for projected letter size. For a proposal, run the proposal completeness check for RFP requirement coverage and readiness. For a contract, run the contract completeness check for clause coverage and execution readiness.
Can I use the output commercially?
Yes. The visuals you render and the reports you generate are yours to use in client work. Free renders carry a Gixo Prism watermark on the preview; removing it, copying clean HTML, and downloading files require a Gixo trial or paid plan.
Will the same input always give the same result?
Yes, and that is the point. Because none of these tools calls a model, there is no sampling, no temperature, and no drift between runs. A palette that scores 4.7:1 today scores 4.7:1 next month, and a deck outline that flags three missing sections flags the same three.
Need to turn the result into the finished deliverable?
The check is free. Gixo's product workspaces handle generation, collaboration, brand controls, and clean editable export.
