The ones people come back for — led by the new Agent that runs the others for you.
Localcraft Agent
Give it a goal and the Agent plans the steps, runs Localcraft tools in sequence and hands you the finished file — files never leave your browser.

Open tool →AI tools
Your key, your device — nothing in between
Localcraft Agent

Open tool →AIAI chat
Chat with OpenAI, Claude or Gemini using your own API key. Your key stays in your browser; requests go straight to the provider.

Open tool →AIReview theme miner
Mine hundreds of product reviews into a theme table with real local counts: what customers praise, what they complain about, and the exact quotes behind every theme.

Audit a product listing against a fixed platform rubric: local hard checks for length, banned claims and keyword coverage, plus a six-dimension scorecard with quoted problems and fixes.

Score a batch of resumes against one job description with a single fixed ruler: per-requirement verdicts, the resume quote behind each verdict, and a defensible ranking.

Turn a meeting transcript into an action list that survives the meeting: tasks with owners and real due dates, decisions, and open questions — exportable to CSV and your calendar.
Open tool →AIContract risk scan
Scan a contract before you sign: clause-by-clause risk findings with quoted text and negotiation asks, a fixed-checklist check for clauses that are missing entirely, and a 0–100 risk score. Not legal advice.
Open tool →AILog doctor
Diagnose a production log without reading it: errors are fingerprinted and counted locally across the whole file, then the top error groups get a root-cause hypothesis and a fix path.
Open tool →AIQuiz maker from notes

Open tool →AITest case generator
Generate a test-case matrix from code or requirements — normal, boundary and error paths — and get a runnable skeleton for Vitest, Jest, Pytest or Go test whose case count is verified against the matrix.
Open tool →AIScript to storyboard
Turn a video script into a shootable storyboard: lines are split and timed locally with a speech-rate model, every segment gets a shot size, visual, B-roll idea and subtitle point, and over-length segments are flagged against your target.
Open tool →AIVideo chapter builder
Build YouTube chapters and show notes from a subtitle file: chapters are named from the real transcript blocks, and every timestamp is validated locally against YouTube rules before you paste it into your description.
Open tool →AIFlashcard builder

Open tool →AIBank statement converter
Convert a bank statement PDF into a transaction CSV with a safety net: rows are extracted locally, unreadable pages are repaired by the model, and the running-balance chain is re-checked locally so dropped rows show up as flagged breaks.
Open tool →AINDA triage
