Mycel
Mycel
Mycel learns a service firm's work from one past deliverable, then drafts every future one for owner approval before it ships.
Key features
- One-Deliverable Onboarding: Upload a single past piece of client work and Mycel infers your firm's format, tone, and structure, so it can draft the next one without a lengthy template build.
- Approval-Gated Output: Every draft waits for your sign-off before it ships, keeping the human as the last pair of eyes while removing the blank-page work.
- Correction Memory: A correction you make once is carried into later drafts, so repeated edits stop recurring month after month.
- White-Labelled Client Portal: Clients get their own sign-in on your brand, with credentials kept separate per business rather than shared under Mycel's name.
- Recurring Desks: Prebuilt loops for accounts receivable chasing, monthly close packs, pipeline outreach, recruiting longlists, and contract redlines run on a schedule.
- Rendered Deliverables: Output is inspected as the real artifact — an actual spreadsheet or document with the exact figures the client receives — not a filename in a queue.
- Job-Based Metering: Volume is counted in jobs (one message answered, sync run, or document produced) with model costs included and no overage charge.
- Apache-2.0 Self-Hosting: The same code can be run on your own servers with your own model key, free and unmetered, for teams that cannot use a hosted service.
Best for
- Agency Deliverable Drafting: A consultancy or SEO agency uploads a past client report so Mycel drafts the monthly version for every account, leaving only review.
- Bookkeeping Month-End Close: Finance-service firms run the close loop and receive a client-ready pack without an owner rebuilding it each cycle.
- Accounts Receivable Chasing: Late invoices are followed up automatically so the principal stops asking clients for money twice.
- Recruiting Longlists: Per-search candidate longlists are screened in writing and returned ready for a recruiter to shortlist.
- Contract Redlining: Incoming contracts come back marked up and ready for signature rather than waiting for a free afternoon.
- Owner Capacity Relief: A founder who is the bottleneck on every draft keeps final judgment but stops being the person who writes the first version.
- Private-Cloud Deployment: Teams with security or procurement constraints self-host the Apache-2.0 runtime inside their own infrastructure.
