Simple SoapCalc

Simple SoapCalc

By Redefined Threads

Create freely. Calculate confidently. Soapmaking depends on getting the numbers right. When the math is off, the whole batch is off. Simple SoapCalc takes care of the calculations so you can focus on the craft, not the chemistry. Describe the soap you want to make. Adjust oils, batch size, or superfat as you explore. Simple SoapCalc responds with precise lye, water, and oil amounts you can trust, every time. Try asking: • I want to make a creamy, moisturizing soap for dry winter skin • Create a beginner-friendly recipe with olive oil, coconut oil, and shea butter (500 g total) • What kind of soap produces lots of fluffy lather? You’ll see clear results right away, along with an honest sense of how the soap will behave and feel. Creativity stays open. The calculations stay exact. No spreadsheets. No second-guessing. Just safe, well-made soap — calculated in seconds.

SimpleBackups

By SimpleBackups

SimpleBackups is automated backup management for databases, servers, cloud storage, and SaaS apps like Notion, GitHub, Slack, and Linear. This connector links your SimpleBackups account to Claude so you can check backup health, investigate failures, and run safe operations without opening the dashboard. What you can do: - Get an account-wide health check in one call: how many backups ran, which failed, which have gone stale. - Diagnose a specific failure using the actual console output from the run, not a truncated summary, so you get the real cause (bad credentials, disk full, permission denied, timeout). - Chart run history across all your backups over the last 7 to 30 days. - Trigger an on-demand run, pause or resume a schedule, and prepare a restore that returns a short-lived signed download link or an rsync command you run yourself. Example prompts: - "Did any of my backups fail in the last 7 days?" - "Why did the production Postgres backup fail last night?" - "Show me the run history for all my database backups this week." - "Run the staging MySQL backup now." - "Prepare a restore of yesterday's Notion backup." How it is built: 10 read-only tools and 4 write tools. Every write tool is reversible and requires a Member role or higher on the connected team. No tool ever returns credentials, API tokens, or sensitive data. Restore links are time-limited and expire on their own; SimpleBackups never runs a restore on your behalf from chat. Access is per-team, chosen during sign-in, and revocable at any time from your SimpleBackups settings. Requires a SimpleBackups account on a trial or paid plan.

SimpleSend

By SimpleSend

SimpleSend is the personalization layer for cold outreach. You bring the lead list, Claude writes the emails, and SimpleSend supplies the research each line is built on, then keeps every draft in your account. How it works in Claude: 1. Point Claude at a lead list — one already in SimpleSend, or one it creates in the conversation from contacts you paste. 2. Describe the campaign: what you sell, who you sell to, the ask, and a sequence of up to five emails (intro, value, follow-up, breakup). 3. Give up to five research targets — the specific things worth knowing about each company. Not fixed database fields: you write them. The vendor a company runs on its site, a recent launch, hiring on a particular team, how they describe themselves now. 4. SimpleSend researches each company from public sources and returns a dossier with sources and dates. Claude drafts every email against that dossier, your brief and your signature. 5. Drafts are checked, saved to your SimpleSend account, and exported as CSV for whatever you send with. What is different about it: • Claude does the writing, so there is no per-email AI drafting charge. You already pay for Claude. • Every personalized line traces to a researched fact with a source, or it does not ship. No invented details about the recipient. • You define the research per campaign. Results are cached 30 days per company, so a shared prospect is not researched twice. • Sequences, not single emails: each step knows what the last one said. • Everything Claude makes lands in your SimpleSend account to review, edit and export. Built for founders, SDRs and sales teams sending considered outbound to tens or hundreds of prospects, not thousands. Scope: in Claude, SimpleSend works from lists in your account. Finding and enriching new contacts happens in the SimpleSend web app.
