The AI teammate
your QA team has been
waiting for.
Tessa AI plans, runs, and reviews testing work end-to-end, across manual execution, automation frameworks, requirements review, and knowledge ingestion. One platform, many specialized agents.
A library that grows
with your team.
Tessa AI ships with a curated set of QA agents, workflows, and skills you can use today, and connects to the tools your team is already paying for. New playbooks land every release.
Plan, dispatch, execute,
all the way to a report.
One conversation kicks off a real workflow. Tessa AI picks the right agents, runs them in the right order, and connects to the tools your team already uses, browsers, mobile, APIs, TMS, knowledge base.
Every phase of the
software testing lifecycle.
Tessa AI doesn't replace one tool, it owns the work that runs across the whole STLC. Below is what it does in each phase, the workflows it ships, and the agents that do the work.
- Phase 01
Analyse user story
Tessa AI reads the story, walks the linked knowledge base, and surfaces the impact: which areas it touches, which existing tests are at risk, which open questions block test design.
- Cross-link the story with existing requirements
- Detect missing acceptance criteria
- Map affected user flows and edge cases
Workflowsimpact-analysisexplore-appSub-agentsanalystresearcher - Phase 02
Review requirements
Two-layer review against your knowledge base: a static text pass plus a grounded pass that quotes the wiki when a requirement contradicts product reality. Critic loop guards against hallucinated findings.
- Clarity, ambiguity, testability checks
- Grounded contradictions with cited wiki evidence
- Risk register + delta against pain-point inventory

Test planning
Tessa AI maps requirements onto a coverage plan: what's already covered, where the gaps are, which scenarios are worth designing first. The output is a coverage map you can show stakeholders.
- Build a requirement-to-test traceability matrix
- Prioritise high-risk and uncovered areas
- Draft a manual scenario when a gap is found

Test design
Generate full test suites from requirements straight into your TMS, or into a shared sheet for review. Every case is traced back to a REQ id so coverage stays measurable.
- Generate test cases with traceable REQ → case ids
- Cover happy paths, edge cases, negative paths
- Push to TMS via MCP, or to a shared spreadsheet

Test execution
Drive the real browser, the real mobile app, or the real CI runner. Manual tests get evidence captured automatically. Autotests get run, retried, and triaged, failures land back as actionable diffs.
- Execute manual cases with auto-captured evidence
- Bootstrap or extend an automation framework
- Run autotest suites and triage flakes

Reporting
Every run produces a publishable report: pass/fail breakdowns, risk register, screenshots, links to bugs. The same artifacts are filed straight into your bug tracker, no copy-paste.
- Compose evidence-rich pass/fail reports
- File bugs to your tracker with full context
- Summarise findings back into the knowledge base

Eight components, one product.
Tessa AI ships as a single web app organised around the work QA teams actually do. Click any component below, the mock cycles through the live UI for each one.
Works with the tools
your team already uses.
Tessa AI plugs into your test management, code, project tracker, knowledge base and chat, no migration, no parallel systems. 14 native integrations and counting.

who own quality.
Stop being the bottleneck.
Hand off the work that drains your week, coverage audits, requirements review, manual regression, framework boilerplate. Tessa AI does the runs, you own the calls.
- Requirements review with risk register
- Coverage audits with full traceability
- Manual tests executed in a real browser
- Automation framework scaffolding in minutes
Ship with confidence, without owning QA.
You don't have a dedicated tester, or yours is buried. Describe what changed in plain language; Tessa AI plans the testing, runs it, and hands you a report a stakeholder can read.
- Plain-language test planning from a PRD
- Impact analysis before you merge
- Manual smoke runs on demand
- PR-ready reports, no QA jargon
Get testing off your plate.
Stop hand-writing test cases for every PR. Point Tessa AI at a diff or a ticket, it generates the scenarios, runs them, and flags real regressions, not flakes.
- Test cases generated from a diff or REQ
- BDD scenarios that trace back to requirements
- Runner that reports failures, never patches them
- Pre-merge impact analysis on touched code
Every job QA actually does,
already a workflow.
One conversation, one outcome. Pre-built playbooks for the work QA teams ship every day, from test design to execution to coverage. Each is a YAML file you can read, fork, and adapt.
Generate a test suite
Turn requirements into a full set of test cases, traced back to every REQ. Pushes straight to your TMS or a Google Sheet.
Run a manual test
Tessa drives a real browser through the scenario, captures screenshots and traces, and writes the report.
Design a manual scenario
Describe the feature in plain language; get back a complete manual test case with steps and expected results.
Audit test coverage
Read-only sweep of your existing TMS against the requirements base. Rebuilds the traceability matrix, flags blind spots.
Map coverage gaps
Analyzes which areas of the product have thin or stale test coverage, and what should be added first.
Impact analysis
Before you merge: which features could break, which tests must re-run, who needs to look at it.
Review requirements
Two-layer review of a SHALL-style spec: clarity, ambiguity, testability, edge cases, plus product-context conflicts.
Reproduce a bug report
Takes the steps from a ticket, runs them in a real browser, captures trace and screenshots, and tells you whether it actually reproduces.
Propagate a requirement change
When a REQ changes, finds every linked test case and proposes the concrete edit, outdated step, broken expected, new gap.
Bootstrap a test framework
Scaffold a new automation framework from scratch, config, page objects, runner, CI hooks, in one conversation.
Add an automated scenario
Turn a single REQ or BDD case into a working Playwright test, wired into your existing framework.
Run the automated suite
Kicks off the test runner, reports failures honestly, never patches a flaky test to make it green.
