Engineering Changelog

Continuous updates, architectural upgrades, and new on-device tools shipped directly to production.

v2.6.0 September 27, 2026 8 New Tools 574 tools live

AI writing, AI images, keyword research, DNS & SERP — eight new tools

Eight tools that were missing from the suite are live, and every one of them runs its core work on your device: the AI modes are an optional upgrade you switch on with your own provider key, never a requirement.

  • AI Writer: writes a full blog post, article, landing page, newsletter or YouTube script with your own LLM key — or, with no key at all, builds the complete writing plan (title options, meta description, section-by-section word budget, quality checklist and a ready-to-paste prompt).
  • AI Paraphraser: a rule-based rewriter that runs entirely on-device with curated synonym, phrase and contraction maps, shows every substitution it made and reports readability before and after. Creative, academic and humanize styles use your own LLM.
  • AI Image Generator: generates from a prompt through OpenAI-compatible image endpoints or Gemini's image model with your key, and draws deterministic procedural artwork from the prompt and seed when offline.
  • Keyword Generator: expands a seed keyword into hundreds of scored ideas — questions, modifiers, long-tail, comparisons, local intent, alphabet soup — plus n-gram mining from any text you paste, with CSV export.
  • Keyword Clustering: groups a keyword list into topical clusters with TF-IDF vectors and cosine similarity at the threshold you choose, with volumes, intents and CSV export. A browser can finally do this without uploading the list.
  • DNS Lookup: A, AAAA, CNAME, MX, TXT, NS, SOA, CAA and SRV records over DNS-over-HTTPS with automatic fallback between Google, Cloudflare and Quad9, reverse (PTR) lookups for IPs, and SPF/DMARC detection in TXT output.
  • Backlink Checker: audits the export you already own (Search Console, Ahrefs, Semrush, Moz or a spreadsheet) for referring-domain diversity, dofollow mix, anchor over-optimisation, risky TLDs and site-wide links, diffs two exports to show new and lost links, and optionally checks domain authority with a free OpenPageRank key.
  • SERP Checker: parses a pasted results page, finds your position, tests every title and description against Google's truncation limits and lists the terms missing from your own snippet — or fetches the live top 10 plus People-also-ask with a Serper or Brave key.
  • Honest limits, stated in the UI: no tool can read Google's keyword volume or the web's backlink index from a browser, so the tools score what they can prove and tell you where to verify — no fake numbers, no uploads, no account.
  • Wired into the rest of the site: new workflow-canvas templates (keyword → clusters → PDF, backlink audit → PDF, DNS → PDF, rewrite → PDF), accurate offline-level badges (L2 hybrid / L0 live-network) and 574-page sitemap and offline precache.
v2.5.0 September 20, 2026 Offline Reliability 574+ tools offline

Offline mode actually finishes — and heals itself

The background download of all 574+ tools is now resumable and self-healing, so the suite works with no connection instead of only working online.

  • Resumable tool sync: an interrupted download (closed tab, dropped connection, browser suspending the worker) now continues on the next page load instead of leaving a partially cached site forever.
  • Automatic repair pass: a second pass retries anything the first pass missed, so a rate-limited or timed-out file no longer stays missing until the next release.
  • Core shell included: shared files such as js/app.js and the stylesheets are now healed by the same sync, not just tool pages.
  • Visible offline status: Settings → Offline mode shows exactly how many files are cached, a progress bar, and a Download all tools button — plus SarvTools.offline.status() for scripts and tools.
  • Generator hardened: the service-worker build script can only regenerate its asset lists now, so it can never again overwrite the offline engine with an older copy.
v2.4.0 August 22, 2026 Major Milestone 574 tools live

574+ on-device tools & KrutiDev Indian DTP Engine

Milestone release delivering 500 complete on-device tools, legacy Indian DTP font decoding, in-place on-screen typography editing, and full-screen document inspection.

  • KrutiDev / DevLys to Hindi Unicode Engine: Automatic detection and conversion for legacy Indian DTP font encoding (e.g. xq: dh efgek ➔ गुरु की महिमा).
  • Interactive Click-to-Type Editor: Live floating on-canvas typography inputs with arrow-key pixel nudging.
  • Expanded Viewport & Fullscreen Mode: 82vh high-definition container with 2.5x crisp rendering.
  • Multilingual Natural Voice Assistant: Unicode script detection for 11+ languages with neural speech synthesis.
  • Workflow Canvas 500-Tool Palette: Visual pipeline builder supporting full dependency chaining across All 574+ tools.
